VoLTE, WiFi calling with the upcoming 3G shutdown - LG V40 Questions & Answers
Visiting the US and trying to find more information on this upcoming 3G shutdown.
From what I have learned from calling/chatting with T-mobile, AT&T, Sprint, Mint Mobile, Boost Mobile, Straight Talk and Consumer Cellular (** all this info is not guaranteed completely accurate as not all cell tech support people actually know everything - not a knock - how could they know everything about 1000 different handsets just saying)
Following anything you see below is certainly without warranty. I am not responsible for bricking your phone or turning it into a coffee maker.
Okay so enough disclaimer. Here is what I think I have learned:
For reference my phone is a V40 ThinQ LM-V405UA. It was manufactured for Sprint - bought it unlocked and refurbished.
AT&T has already shutdown 3G calling and all voice calls are now on VoLTE... but maybe not in all areas??
T-Mobile and it's MVNO's still have 3G operating and plan to shut it down in July.. ish...
Mint Mobile and Boost shows my IMEI to be compatible.
Consumer Cellular show my IMEI to NOT be compatible.
The AT&T store told me in person that I would NOT be able to enable VoLTE on my phone with the network since it was made for Sprint
AT&T Chat - escalated to Technical Support - confirmed that there was no way to enable VoLTE and that it would not function on their network.
Chatted with T-Mobile, Sprint and LG - they could not tell me any service codes or techniques to enable VoLTE. Each did kindly tell me I should check with LG, T-Mobile, Sprint...
*#*#4636#*#* brings up the Testing Menu
Under Phone Info you can switch on "VoLTE Provisioned"... (YES!! - right? ...not sure this does anything)
Below that is a toggle for "Wifi Calling Provisioned" . Mine is grey'd out in the off position
You can set the preferred network type - and mine is set currently to LTE/CDMA/UMTS auto (PRL) - not sure what that means but...
You can enter the "HiddenMenu" by dialing *#546368#*405#
I clicked all around and found only one thing
Click SVC Menu
Scroll down to VoWiFi (Ahaaa!! right??)
Click on Wi-Fi Calling Toggle and change the value to 1 - on
I rebooted and... no change.
I currently have a Mint Mobile sim (T-Mobile towers) and it currently works. Gleaning from what I read somewhere - if you truly have VoLTE activated and configure correctly you should be able to have data to load a web page DURING a call (with WiFi switched off). Mine fails to load during a call.
If you have VoWifi configured and activated correctly you should be able to make a phone call having Cell data switched off and attached to WiFi. Mine can not make a call.
My wife's Xioami phone does all of this and even has little VoLTE symbols at the top of the screen.
Hopefully all of this information helps someone else - but even better yet - hopefully someone can tell me if I will still have cell service in July when T-Mobile is shutting down their 3G service. Are there other tests I should be doing?
Also for fun - pulled my LG-V20 from the drawer and messing with it. It shows that WiFi Calling is WORKING... Battery is bloated but I think I had a successful test with it.
Anyway - that is where I am at. All tips, tricks and ANSWERS are appreciated.
I don't know if flashing it to the AT&T or open market version rom would do the trick but probably would. Note, since it's refurbished you sure it wasn't already reflashed to the open market version rom? If so it should work!
AT&T might have gotten confused by your description...
AT&T whitelisted phones:

My understanding, and it could be outdated, but maybe not, but at&t (supposedly) checks imei, and if it's not one of their phones, there's nothing you can do to make it work. From your description, it *sounds* like they are still doing this.
For VoWifi to work, with my mint mobile sim at least, you have to go to your mint account and turn on VoWifi ability. So not only does the phone need to be capable, the sim needs to be provisioned for it. Many people overlook this part.
There are numerous indicators of VoLTE working. Many times when you bring up the dialer there's a little HD symbol on the talk button. Other times it will give you a little LTE symbol on the status bar when making a call (and it doesn't change to 3G during call), etc.
The VoLTE situation is where 'what rom are u running?' becomes very important. The lte bands that the rom is capable of need to coincide with the carrier you want to use. The 'Open US' roms have the most bands available, and is usually a great choice for T-MO (and mvno of t-mo). Even has band 71 (which is only used by t-mo).
Lastly, for those that may not be aware, after market roms, like lineage, aren't capable of VoLTE (or VoWifi), for most LG phones. that's because LG (and Sammy) both use a 'proprietary' IMS stack, which means those Vo technologies only work on their phones with their roms.
AT&T doesn't care about who's phone it was as long it's imei isn't blacklisted.
What is important is the hardware which can't be changed or the firmware which can be changed.
My guess is the issue is the former. The carrier variant phones can have slightly different hardware configurations.
Thanks gang for the notes.
I'm running stock rom. I'm not rooted nor bootloader unlocked. I'm a bit resistant as this is my daily driver phone plus there doesn't seem to be clear confirmation that cross flashing something will really result in better performance. Add to that I won't be able to reinstall whatsapp nor my banking app etc - since my home country sim and phone number (Colombia) won't receive a confirmation text until I return there in October. Tough situation.
But I've got more test results
@AsItLies - thanks for that - I was able to enable wifi calling in the Mint app. I also called consumer cellular to confirm that my sim had volte and wifi calling enabled on their end. This was all done before testing below.
I found some exciting new settings inside the hidden menu.
Dialing *#546368#*405# choosing: Field test / GPRI VoLTE+VoWifi / IMS / Slot 0
VoLTE was enabled (possibly from steps done above in my first poat?) But I was also able to enable VoWifi ViWifi and ViLTE. I enabled them all.
After making that change I dialed the Testing menu - *#*#4636#*#* - Wifi calling Provisioned and Video calling Provisioned are still greyed out in the off position. VoLTE Provisioned is still on.
Testing - I can make a call using a Consumer cellular (At&t mvno) sim. I can not get cell data during the call though- same results as with my Mint mobile (T-mobile) sim.
I was told that At&t has already shut down all 3G calling so my phone MUST be using VoLTE if the call worked?
I have read unconfirmed reports that not all 3G calling has been shut down since some of the cell towers have not been upgraded yet... so could be I just get lucky.
My wife's phone can make calls with either sim AND get cell data during the call. (so does that prove that the nearest tower must already be upgraded?)
My wife's phone has nice symbols and setting sliders for wifi calling and volte calling - all enabled
I tried running tests with airplane mode on and wifi enabled - but it wont make a call that way on my phone or the wife's phone.
So basically it seems like nothing has changed. I'm still not convinced that I will have a working phone in July ish... Any more tips on testing and verifying that are appreciated.
It's likely running on 4G VoLTE.
This is how my Note 10+ is configured, no changes were needed.
@blackhawk - My screen looks very similar.
My preferred network type is set to - GSM/WCDMA/LTE (PRL).
I am not sure if that was the default or if I fiddled with that... I am going to dink around with that and see if changing that solves my problem. But
But I did some more testing. I was away from the house at the grocery store. I dialed my phone with Mint Mobile sim in and my 4G symbol changed to 3G and the call went through. I did have data during that time - but painfully slow.
Grabbed the wife's Xiamoi phone with her Consume Cellular (AT&T Mvno sim). Dialed and the 4G symbol stayed on and she had data of a reasonable speed.
So - I am believing... not proof... that my phone is still dropping to 3G to make calls and is skating away on the still operating 3G system of T-Mobile. Evidence that I might be without calling in July.
I should test the reverse - and pop the sim out of the wife's phone and try my phone with an AT&T sim and see if I had no calling service.... but she doesn't really like when I pop open her phone in the grocery store. She puts up with a lot - but I didn't have any "geek credits" in the bank so I will have to plan for that later...
Anyway - that is the latest.

Set it to that setting I'm using.
Clear Sim toolkit data.
Network reset and a reset on AT&T's side too.
The APN profile should ATT Nextgenphone I believe.
@blackhawk - thanks. I have an AT&T sim to fiddle with now (Straight talk this time).
AT&T only gives me 1 bar here in my house.
It seems no matter when I chose as my Preferred network type - I get
Out of service area / Mobile network is unavailable
SIM not provisioned for voice
But I don't have a SIM toolbox on this phone. Can I get that installed without root? Can you point me in that direction. Because maybe that is what I need to do next is clear that - especially since I keep popping in random sim cards.
Thanks again
Oh - skip that - brain dead. I got the sim toolkit cleared...
On with the testing!
Did some testing again with my Mint SIM - i get 4 bars here...
Did you know that you can have the dialer, Testing menu and Sim Toolkit settings page open/split screen or background screens at the same time? Well that saves some time... By the way the HiddenMenu won't stay open as a background page... Just so you know.
So here is my testing sequence: Wifi switched off. Dial the local automated weather number and then switching to the Testing menu to watch the reported "Voice Network Type" . Record results. Enable Airplane mode. Got to Sim Toolbox and clear data. Disable Airplane mode and try a new "Voice Network Type".
Basically all of the settings for "Set preferred network type:" that include UMTS or GSM will work. But the Voice type drops to GSM or UMTS. Data drops to UMTS , HSPAP or sometimes EDGE. 5 seconds after the call ends the Phone Info page reports "Voice Network Type" and "Data Network Type" as LTE.
Any settings like LTE Only or something that doesn't include UMTS in it - the calls just fail. Actually - if the "GSM Service" inside Testing Menu/Phone Info reported "Emergency Calls Only" under "GSM Service" - then you can bet the call failed. Despite really wanting to do complete testing - I did not dial 911 to see if it would work. Just seemed wrong to potentially interrupt a real emergency - even in nowhere USA.
I found some more interesting settings inside HiddenMenu / IMS Setting / GPRI VoLTE / Slot - 0 / Roaming
Inside there are VoLTE and VoWifi - I enabled all the roaming options inside each.
But - alas no change to my tests so far.
I tested the Wife's phone on Straight talk and the Mint sim = VoLTE symbol
So that is one AT&T and one T-Mobile MVNO
Preferred Network Type: LTE/TD-SCDMA/UMTS
Worked great. Testing page showed that the voice call stayed on LTE. I enabled Wifi and tried getting it to transfer to a VoWifi call but - even with 1 bar it wouldn't go. If you have 0 bars it won't initiate a call. Probably a security thing as they don't know if you are a real subscriber??
Anyway - I think that proves?? that my phone is still not doing any VoLTE nor VoWifi calling and will likely fail or have extreme problems as the 3G network fades away.
On my N10+ the hidden menu stays open until I close it. Makes things easier.
Get the carrier advanced tech support to troubleshoot it if possible. You probably know more about than me at this point.
I can highly recommend a Note 10+ N975U1, they run great on Android 9 or 10; Android 11 and especially 12 not so much so. I have two, just bought another new one about 5 months ago.
It's a better flagship Samsung than the ones Samsung released after it in my opinion.
New factory sealed ones are available still for $800 and used ones in "excellent" condition for half of that. In a good case they will easily last 3+ years with only battery replacements. The one in my hand is 2.5 yo and looks/runs like new with zero display degradation. It's heavily used. Current OS load will be 2 yo in June, still fast and stable with minimal maintenance. Supports up to 1tb expandable storage.
Both the N975U (AT&T variant) and the N975U1 (unlocked) run seamlessly on AT&T. There's a 5G variant but it will likely eat more battery.
It's display is one of the best, maybe the best in any smartphone even today It's gorgeous with an exceptional color rendering index and white point. Being 60hz means less power consumption and better color rendering/calibration, great for vids.
It's just a snappy fast fun work horse of a phone that has excellent build quality.
Lately Samsung and Google Android have been subpar... dropping balls.
That is a smoking fast phone! I may have to give this phone up and move on. But that has issues of it's own as I will still have to keep this phone around because there are a bunch of apps I won't be able to install on a new phone because I can't get my sms confirmation until I get back to South America. But not a whole lot of other options.
Thanks again,

You're welcome.
It's a true pain migrating to a new device. I hope you get that one successfully running on VoLTE.
If you like that large of a display, it's form factor is still the best. Better display to bevel ratio too. Lighter and thinner the S22U with better SOT.
Watch this vid where the N10+ literally smokes the S22U after both rams get loaded up with apps. wtf? I'll take the dinosaur Note...

Urbane 2 LTE not working
Hello All I purchased a refurbished Urbane 2 LTE (W200A) from here . I put in a T-Mobil SIM but it will not work, under SIM status says out of service, T-Mobil checked the IMEI # and says it is fine but might be carrier locked? Any thoughts/ideas on this issue? Cheers,

Cheers, Click to expand... Click to collapse Welcome! I've had mine now about 2 weeks. I bought an UB2 which was unlocked. I had the same problem. Reboot the watch made it work in my case. I have a T-Mobile and ATT SIMs. The ATT SIM worked right away, the T-Mobile would not work right away but rebooting the watch made it work. Now that could have been coincidence, say T-Mobile takes a while before it lets an unknown IMEI into its network? Hopefully that fixes it for you. Next, I spent a time experimenting, moving around with the ATT and T-Mobile SIMs. I found the lack of the lower frequency bands meant it often ends up easily offline, not even 2G, that problem was more common on T-Mobile than it was on ATT. I also found when using LTE the battery is pretty bad, whilst BT or Wifi tethered to the mobile I lose about 5% an hour, so does a reasonable job of lasting through the day, on LTE I was losing 25% an hour so 4 hours. Once I learned that, meant I'd not really be away from my phone for long periods, so I now know its more for brief periods when not having the phone is helpful. The classic use case would be running,, or short bike rides. Therefore I'd be really using it in case someone was to phone me (I use Google Voice), so given the ATT network benefit, I got a Truphone SIM which is free for incoming calls, and I use Hangouts for texting which uses less $ than sending a text. I also after having the Truphone SIM for some days learned the UB2 easily often loses the BT and Wifi signal and goes to LTE and so I was being charged for "accidental" use so I disable UB2 cellular altogether and enable when I deliberately are going without my phone. $190 + shipping is a little high, you normally can get in the $180-$185 total including shipping on ebay. There is one for $172 but they charged state tax making it nearly $200, but I got this one for $185 and worked fine looks as-new in a slightly tatty box.

Click to expand... Click to collapse $169, excellent, just the link you gave says $190 now. So I'd say from my experience where I live (northen California) that ATT would be a better bet for the UB2's bands. It may be the case T-mobile's frequencies in your area are not overlapping the very limited bands of the UB2. T-Mobile's primary band is 12 which the UB2 doesn't have. In my case if i were outdoors i could get LTE but indoors it would go to 2G. ATT however tended to stay on LTE more often when indoors. The other option is yours is locked. I don't know how to tell if its locked. What does SIM status (settings, cellular, SIM status) say? My working UB2 shows Network: Truphone (what I have inserted presently) Signal strength: -112dBm 29 asu , Network type: LTE , service state in service,, roaming: not roaming, network state disconnected (as I'm on my BT to my phone). When I swipe down from watch face it shows as 1 or 2 LTE bars. When I came across some lower priced units they were in fact locked, I saw units for $170 but in fact locked, and I was told you could buy an unlock code on ebay. A quick search now indicates you can buy for about $8
I've yet to actually see a LGU2 that is locked. Some sellers assume they are but they usually aren't. I purchased mine directly from AT&T and it was never locked. The same for the Sport. Others have purchased from AT&T and used them on other providers. I guess it's possible for used watches that were activated on AT&T to be locked? Not sure though. As far as battery usage on LTE, could it be a weak signal causing the problem? Without cellular on I use about 3%-4% an hour and when it's on I use around 5%-7% an hour. Of course if I take calls it will drain faster, but just idling doesn't affect it too much. I also set my preferred network to 3G because HSPA speeds are plenty fast enough for me and more readily available with strong signals in my area. I only exceed the 25% drainage per hour when I'm tracking runs with GPS. I have 3G on, bluetooth headphones for music and GPS tracking during runs. I can use 35% an hour running. I only use 3G when I run so I haven't tested the data usage when i'm connected by BT. Most of the time 3G is off. I don't have GV and forward my calls to the watch during runs. I don't give out the watch's number so I don't have a reason to leave it on.
OK I have this working now, I had to mess with settings a few times and disconnected BT for LTE to come up. Now the only issue is when making calls now, if I try to make a call via watch, the call drops almost instantly, the cellular connections drops and I have to reboot to watch to get LTE to work again.

Click to expand... Click to collapse I think T-Mobile and UB2 aren't good bed fellows. I'm thinking you drop down from LTE when making a call and its really reluctant to go back to LTE. What happens if you change from LTE preferred to say 2G or 3G preferred?
Got T Mobile APNs loaded?
Yes but is works but very sporadically, according to seller below, anyone have there phone working with add on account? "The issue is not with the device it’s trying to use the device with Tmobile’s wearables add on. The device can be used as a standalone device as a new line with t-mobile, but if you are trying to use the wearables add on plan that won’t work.."

Click to collapse That sounds fair. If it was a specific wearables T-Mobile plan you'd have to get a specific T-Mobile device. Mine worked on T-Mobile when move the SIM from my phone to the UB2. What I'm finding is the UB2 drops BT and then tends to go to LTE before Wifi and it pulls some data when no good reason, so disable cellular and enable cellular when standalone, lowers the bill. I did phone up T-Mobile about wearables, I was considering the Samsung Gear S3, but it was plain bad value, they wanted $15/month to add a wearable, well the UB2's capabilities struggle to pull more than a few MB/day because otherwise it drains battery too much and it gets very hot and disconnects too often to use it for many calls. There are much better plans out there. I'm on Truphone which is based on ATT and mostly disable cellular when have my phone with me and enable when I leave the phone. I'm extrapolating about $5/month.

AW2 has its weakenesses now but not expect after a couple of performance tuning releases it will improve the standalone capability, of which one of which is a backup phone if you phone breaks//lost so having a PAYG sim to fall back on is a useful safety net.
Actually seal is just like any watch, keep it lubed with silicon and replace it every year or 2 depending on climate. What is this other carrier you using ? I do like the idea of a back up, just not for more than $5 a month.

I do not think its any issue with the wearables thing on Tmobile. Not with this device at least. I'm all good here with mine , I did encounter this issue but it was a galaxy tab S Lte that was mobile data only , no calling / Sms features or radio so it would not connect to Tmobile.

VOLTE T-Mobile, not working (WORKING as of last update)
I'm experiencing issues with VOLTE on T-Mobile. My phone switches immediately from an LTE+ DATA connection to HSPA the moment a call is placed. Of course, VOLTE is enabled on the settings side. I'm running an unmodified system, upgraded to PIE. I've been on the phone with T-Mo to make sure the APN is correct (nothing special to mention here). I've also tried different connection combinations using the *#*#4636#*#* with different results but, even though the phone connects really fast to DATA (LTE+), I cannot get VOLTE to function in any case. On the other hand, WiFi calling works just fine. On a chat with Razer, they just told me that VOLTE is unstable with T-Mobile and, to disable the function altogether from settings. Before I give up, I'm asking the geniuses here for ideas or experiences? Any ideas anyone?

Im waiting for my Razer 2 phone delivery and also on T-Mobile. What OS are you running? Android Pie?
Yes, I'm on Pie.
Good news! with today's update (3-20-2019), my phone is using VOLTE technologies to connect audio calls. Phone calls sound immensely better now (the "HD" icon shows up during the call and the "LTE+" connection indicator in the status bar remains through the call).
Unlocking LTE bands on a US Cellular LM-V405UA that is now on Google Fi?
TL;DR: USCC -> AT&T -> Google Fi -- Any way to get 4G/LTE on these carriers? Hey all, I haven't been very involved in the rooting/flashing/whatever scene since the Gingerbread-KitKat days, so my apologies for what might be a noob question, or if it even is the right question to ask. A bit over a year ago, I switched from US Cellular to AT&T and brought my V40 with me. Despite some IMEI issues (was only 14 digits instead of 15, which messed with some online forms), I eventually managed to get it transferred. However, there was one big issue: I was only getting 3G/HSPA+ service. I imagine this would've been a deal breaker for most, but since I only really use my phone data for music streaming and Google Maps when I'm driving, it wasn't that big of a deal for me. Then, recently, I switched to Google Fi to save money. I knew that the V40 didn't support the fancy carrier-switching stuff, but I didn't care as long as I had some sort of service. The same problem still persists, however: I only have 3G/HSPA+ service. When I briefly looked into this last year, I remember seeing something about flashing some firmware that'd unlock the non-USCC LTE bands, but I'm not sure if this was valid (could be misremembering). Would flashing some sort of firmware on my phone allow me to have 4G again, and if so, what would I flash? The generic US unlocked firmware? Also, not sure if this matters, but GSMArena and LG's own website both seem to state that the US Cellular's V40 model is the LM-V405UA0, but my model number according to Settings is LM-V405UA (no zero at the end). My phone worked fine on US Cellular, so I'm not sure what difference there is between the two models, if any. edit: Messing around with my phone settings, I was actually able to force a 4G LTE signal from T-Mobile (Google Fi's primary network iirc) under Settings > Network & internet > Mobile networks > System select and flipping the Network mode option between "Global" and "LTE/GSM/UMTS". Going from the latter to the former will switch me to 4G/LTE from 3G/HSPA+, but going in the opposite direction keeps me on 4G. To revert, I have to go further into the GSM/UMTS settings and select "UMTS/HSPA/HSPA+ only" in the Network submode option. Both the 3G and 4G options had about the same (slow) network speed of 2mbps down, and according to Signal Spy, the LTE was probably using band 4 (it had a question mark beside it, implying it wasn't very certain). I don't know if it's a band issue or a location issue, but since I'm on WiFi most of the time nowadays, I'm not that pressed about it... maybe I'll back things up and flash the US Unlocked firmware as a weekend project sometime.
Question Data not connecting on ATT since "3G switchoff"
So on Monday ATT decided to deactivate my sim card because they believe my phone is incompatible with their network now. All my bars went to 0 with an x on it and I couldn't do anything on the phone. I went to an ATT store, got them to give me a new activated sim and I put it in my phone and all my bars came back. My phone says VoLTE again too by the signal bar area. I also tested a text and it went through fine. I received a phone call and while it works fine, it sounds like junk now. Like it is no longer actually using VoLTE like it always has. My phone doesnt seem to have any data however, when it should have LTE just fine. I also cannot make any calls, even though it says VoLTE on the phone, it just re-routes to ATT customer service instead of going through with the call. When I go into the network area in settings it says no IP address either. I looked and my APN is set to nxtgenphone, Preferred Network Type selected on LTE. Before ATT deactivated my sim card LTE has always worked fine, and LTE should still work fine. It is only the 3G network being shut down. Also given the fact I have the VoLTE icon the phone is apparently connecting somewhat to an LTE network. So does anyone know how to fix settings to get data working again? Is it just an APN that needs to change? What is everyone else doing with the network shutdown and has anyone else had issues like this?
I had the exact same issue, your issue is in fact APN settings I'm having them as well. Try deleting your current APN and putting in a new one. Once I got a new sim my APN reset I could call but no data and no text. I have half of the APN information in place and have data and basic text, but once I input the MMS port the APN data disappears still trying to figure that out. Not sure if anything I typed is helpful but at least you know your not alone with a mi11 on ATT and it can work EniGmA1987 said: So on Monday ATT decided to deactivate my sim card because they believe my phone is incompatible with their network now.

I tried deleting the MMS port and also the proxy just now and data didnt come back. I will try searching around for more APN info for how phones are supposed to connect now and see if I can find anything.
It looks like from what I could find that it is due to an IMEI whitelist ATT has, blocking data connection on any device not in their whitelist. The solution seems to be to root the phone and change your IMEI to a whitelisted model.
While my phone is rooted my IMEI is not cloned I definitely would not share my IMEI with ATT. When I got my sim card yesterday I had the attendant activate but I did not provide my phone so he did not get the IMEI from my phone. If you got a sim and they input your IMEI that could be a problem possibly. Just a suggestion to try and get a sim activated at a store without your phone.
I had also heard that most ATT MVNOs were not having the device whitelist forced on them yet, so I went and tried 2 different ones yesterday. Both failed to get the phone working on their network with their sims. Before I went through the hassle of rooting (and most likely losing payments) I tried ATT again anyway. I used their online customer service chat and the first person I chatted with said he could help me with the lte data problem and the IMEI issue. I was skeptical, but he actually did fix it all up. He just needed my sim ICCID and my phones IMEI1 and he submitted the info to their backend people for adding to their system. It took almost an hour and a half for it to get added, but overall it was a pretty painless process and I was browing the web most of the time while waiting in chat. I now have LTE data again, VoLTE again, and "5G" too (which ATT 5G is really just one or two more features than normal LTE and is no faster in speed and uses LTE data bands). I attached a screenshot showing the data and VoLTE working on my phone. The first signal is ATT, the second is TMobile (which has always worked and never had an issue, their 3G network shutdown is going on for another 4-5 months)

Click to collapse Happy you are back up and running and I'm glad that you found someone at ATT to do the fairly easy work of getting your IMEI cleared. Lots of people have been worried about devices not working on ATT because of this whitelist issue glad to see there are workarounds just wish ATT didn't make it so convoluted.
Enhanced 4G LTE Mode "in" Mobile Network setting, and CDMA-1xRTT instead of LTE in Mobile voice network type in SIM Status
So, my wife and I have had two of these phones, Moto G6 phones, for about 4 years. And in that time, they've worked great using the Straighttalk (verizon) network. Recently though I switched to the Mint network because they said my phone was compatible ... even though it looked to me that they were a GSM. They also indicated I was in a great 4G coverage area. But, Coverage was terrible. I couldn't place calls in MANY of the neighborhood locations I used to be able to with straighttalk. And, other people said they would call me and they would never hear my phone start to ring. Nor did mine ever show I missed their calls. It was difficult but I finally got my phone switched back to straighttalk. But ever since then I have found that I can't place a call or text out in places I used to be able to. This has been going on for a few months. Recently I was comparing my phone screens to my wife's and found two items that are different, when I think they should be the same. In mobile network settings my phone does NOT show Enhanced 4G LTE Mode whereas my wife's does. It's simply not on my screen of information. Also, in my SIM Status, my phone indicates the Mobile voice network type is "CDMA-1xRTT" whereas my wife's simply says LTE. Are either of these two settings responsible for my not getting good calling service, and if so, is there a way to change my settings to hers? There is nothing I can see anywhere that I can change in all my settings that seems to effect this. Do you think doing a factory reset my get me back to Enhanced 4G LTE Mode? I vaguely recall that the Mint sim was making some kind of changes to my phone. Any other ideas?
Mint is obviously a GSM network since it's based on T-Mobile, and it works quite well on my G6, unlocked and bought from Motorola directly. If you have a Verizon phone (which that CDMA-whatever talk sounds like), then you're going to need to stick to Verizon most likely. I have no idea if there is a Verizon specific G6, but I bet there is. RedPocket has Verizon options also if you are looking at cheap MVNOs. And of course, using an MVNO you need to make sure your APN is right.
