vivid lte issues

I have a vivid that I've been through hard times with. Went crazy for ics and bricked it for half a month. Then switched to iPhone.. now back to vivid with ics but no LTE. Originally the problem was that I had iPhone imei on the account but not anymore. Just doesn't work unless I use alternate apn settings. Any ideas?

It is likely that you will have to manually setup the AT&T PTA apn (assuming you are with att as you mentioned Vivid and not Raider). The apn is usually the cause for the problem that you mentioned. Do a search in the forum and it will give you the apn settings that you need.

So I did add the PTA and LTE apps. I'm on stock Rom, ics, AT&T. And no LTE. Still. All I can use is hspa+ .
I'm kind of surprised nobody else has this problem. Stock Rom seems full of bugs to me.

I had this problem before. All I did was set up the at&t apn. Applied then turned on airplane mode then wait a little, turn it off. That didnt work the first time so I restarted. Are you in a LTE area?

yeah dfw. I.will try doing a battery pull.

Did it work?

same issue
I actually just bought my Vivid as well from eBay (supposedly new) and it came preloaded with ICS. I wasn't able to get any kind of internet connection with my old Atrix sim even though it showed 4G in the notification bar.
I went to an at&t store and they gave me a new sim and now the internet works but i'm definitely not getting the 4g lte icon or speeds of that nature via speedtest app.
I've tried both airplane mode and pulling the battery, with no results. I'm thinking of doing a hard reset now. *sigh*

And just to update, a hard reset didn't do anything.
I'm in San Francisco by the way. What's funny is that when i looked at the demo phone inside the at&t store, the icon for LTE wasn't on that screen either. That phone was running ICS as well.

Mine came with ICS & showed 4g lte when it is in range. you do need to have an LTE data plan for the apn to work to connect you up with LTE. I figured that one out the hard way. Call them up or browse online for the LTE dataplan of your liking.

I'm also in the bay area as well, within 2 miles of a LTE signal tower. Did you get a new SIM card when you got your Vivid? Because when I went to an AT&T store to upgrade my phone to Vivid, they had to give me a new SIM, because it was running LTE and that would not work if you have an older SIM, which at the time I had. So make sure you asked them for a new SIM card!
Never mind, just re-read the above post, you got a new SIM card. Sometimes it would happen for any kind of reason, I would just walk back into the AT&T store and ask for a new SIM or new Vivid

Yes, make sure you do have LTE specific data plan, as older data plans while work, will not allow you to connect to LTE data.

Make sure they gave you an LTE sim and that switch over the IMEI because my brothers had the same issue

Can this device the 4G one work on tmobile Hugh speed network?

Sent from my SGH-T999 using xda app-developers app

Probably not. T-Mobile's and ATTs 3g bands were different frequencies (1700mhz vs 850/1900). However, in some places T-mobile has started to use 1900mhz and unlocked ATT devices will work. This seems to be random right now and even T-mobile support may not be able to tell you where.
Or you can do what I did, and get nrvate's CM10 build for the i957 (I'm a noob so no links for me yet) then flash this radio: Tmo_SGH-T989_UVLE1_radio.zip (Google it). I get full HSPA+ and have clocked DL speeds up to 19000kbs. Of course YMMV, and no guarantees that it will work for you, won't brick your tab or kill your pets.

WHOA!, are you saying you are getting HSPA+ on TMobile!?
can you PM me a link how to do this. I have my tab rooted, but no roms installed yet. Do you have the links for the roms? What recovery are you using to flash?
Thanks!

Yeah it works well with the only problem being the power usage is rather high, and drains faster in idle. After looking at logcat I think this radio doesn't go into idle mode properly so keeps sucking power when not in use. Running it's a little less usage (maybe 30 min less) but on idle it drains in 24 hrs. Turning off 3g helps but for me I can live with this to get 20mb down. When ICS for the i957 finally shows up it should be possible to see a better radio get put in CM10 (which is still in early development, but that's what the ROM below is based on).
I'm using TWRP for recovery. After Clockwork being kind of wonky I have seen the light and use TWRP on all my devices. It just works.
The ROM is here: http://forum.xda-developers.com/showthread.php?t=1867579 and go to post#2. There are some issues but it runs remarkably well for being like 3 weeks old.
This is the radio I used from a Galaxy SII. Google Tmo_SGH-T989_UVLE1_radio.zip and get it from Dev Host. I found out about it looking at radios for similar hardware and found that the Note is close so I took a chace and did it. So far so good!

This is great to hear. I am going to hold off for now, as I would have to open a TMobile account, and I really dont NEED to have this until I start traveling in a few months.
Now what would be AMAZING, is if somehow this tablet could work on verizon. I have a huge corporate account with them and it would cost me next to nothing to add the tablet to the account, assuming it would work. I didn't think it was possible, but then again, I didn't think TMobile high speed connection was possible either.
Any idea if there is a way to get this working on verizon? Or if anyone is even trying?

I can tell you that is impossible. T-Mobile uses GSM and Verizon uses CDMA. You can only put a SIM card device on GSM carriers (TMO and ATT).

I could not tell you as T-Mobile doesn't have LTE yet. TMO will use a band that the i957 can support, but it will probably take another radio (if any) to work. I've seen 21mb down from HSPA+ so even if I never see LTE I can't be too disappointed

Yes it is. The device was locked at ATT and AFAIK there is no other way other than going through a unlock service. I used cell​unlocker.ne​t. $25 and your IMEI gets you a code in a few hours.

As I said that is impossible because the carriers use incompatible setups. SIM card carriers (GSM) will only work with other SIM card carriers. Verizon uses CDMA with no SIM cards. The networks themselves are completely different and hardware cannot be hacked to work. Most of the world uses GSM with SIM cards and if you travel overseas, you'll need a GSM device to use unlocked devices on any networks. Blame Verizon for picking a standard that 80% of the world doesn't use

Has anyone tried flashing the tmobile high speed radio but on the current rooted stock ICS rom instead of the cm10 rom?
In other words, i have a stock rooted sgh-i957 on samsungs ICS rom and i want to be able to use tmobile high speed network (HSPA+). Does anyone know if thats possible?

3g on. Verizon

Do I have to keep my connection on global if I get to an area that my LTE drops off to get 3g? I had it set to LTE but got the roaming so I put it on global got 3g then got LTE when I got service back. Is this the normal process? I just got nexus 6 and wasn't sure if this is normal. Running cm12

Set it to Global if your outside of US territory LTE (Recommended) if you're within the US. Always remember to enable Airplane mode or Reboot when making the changes as a precaution.
Sent from my Nexus 6 using Tapatalk

Global and LTE are exactly the same if you are using a Verizon sim card. Global just allows you to use a GSM sim (typically for overseas travel).

Ok so I noticed if it drops I don't get 3g so is their a way to get 3g. My situation is when I put my phone in my locker it loses 4g and would default to 3g now I just get a ! On the network signal. So did I lose ability to get on 3g. I think I read on here that can happen
Yes surely lost 3g cause if I switch to 3g it gives me the !. So how do I restore 3g

I had same thing. Turned on Allow Roaming Data, and it goes into 3g. I'm assuming that since I'm in my home area, this won't cause me incur roaming charges.

Anyone figure out a solution for this yet?

Mine will get 3g just have roaming enabled. With the way big red is kinda makes me nervous. Do you need roaming enabled to get 3g?

My roaming is off and mine will go between 3G and LTE with no problems. It does that a couple times a day at my work.

I found that on stock ROM it switched 4g to 3g fine. On aosp Roms I need to have roaming data enabled to get 3g and it says I'm on network 0000000.

I remember santod040 fixing that issue on HTC one m8 or was it digitalhigh I don't remember.

Can you people who are claiming that phone switches to 3g confirm that you are on Verizon? I was not aware that that this phone works on Verizon 3g since it is CDMA technology.

Yes am on vzw can get 3g without enabling roaming on stock rom, on custom roms at least the ones I've tried roaming needs to be enabled to have phone switch between 4g and 3g. N6 has only two variants us and the rest of the world. The us version has a cdma radio don't know about the other. Also on verizon there is no voice and data at the same time... yet may have it in the future.

Used Verizon G2 questions

I just picked up a used verizon G2 to use on the Straight Talk service. First issue. I pulled the sim card from my old straight talk phone and put it in the G2. It instantly said unknown sim but, when i restarted the phone i had service. Problem is, i still have the unknown sim icon and cant seem to use LTE. Second issue. im stuck on 4.4.2 because it will not allow me to download any system updates. Im hoping there is a way to manually update. Any help would be greatly appreciated!

If you want to update hook up the phone to a windows pc and install the verizon software updater that is built into the flash memory when you plug it in. It will download and apply the Lolipop update. You should figure out what straight talk sim you have because it could be a verizon one, but most likely it's an at&t one so you'll need to edit your apn settings.

What provider is your Straight Talk SIM running off of? T-Mobile? AT&T?
The Verizon G2 only has LTE bands 4 and 13. B13 is Verizon-only, while B4 is used by multiple carriers.
If T-Moible, B4 is the primary band, but if you are in a rural area that TMO refarmed, LTE will be on B2 instead.
If AT&T, their primary LTE band is B5, but there are some select areas that have it on B4 also.
The "Unknown SIM" icon is because the Verizon ROM detects a non-Verizon SIM card. I'm sure there are ways to get rid of it via rooting, or just flash a custom ROM. If your Straight Talk is going through T-Mobile, there's a T-Mobile ROM in the dev forum that adds some TMO functionality like Wifi Calling.

I was able to upgrade to Lollipop using the verizon software and my pc so thanks for that!
The sim I am using is an AT&T straight talk sim. Do they have a sim just for verizon LTE networks?

For new lines, you can stick your phone's IMEI into ST's BYOP checker and if it checks out, you can order a Verizon LTE SIM. For existing lines, probably easier to just call up CS and ask.

I just ordered a verizon LTE sim card from straight talk. They transfered my number to a new sim once before, I'm sure they can do it again. If not, I can live with a new number to have a working phone again.

I am reading all kinds of conflicting stories. Some say it'll work, but 3g speeds only. BUT, it appears that MAYBE the VS980 can now use verizon 4g towers . . maybe in the last few months. Can you confirm? THANKS in advance. I have a rooted Verizon LG G2 (VS980) that I LOVE .. but i would really love to save a few $$$ and use Straight Talk. Thanks again.

I am using the Straight Talk CDMA service on a few of my phones at the moment. I usually use a Nexus 6 but I had to send it in for a problem and have a Verizon LG G2 and a Verizon HTC M8. The sim card works on both of these phones at LTE speeds. At least in my area, Verizon still seems the most reliable for me. It might not be the fastest service but I don't have issues with missed texts and dropped calls like I do with some other services I have tried.
Hope this helps.

Cricket, Att Will this work?

Hi all, will this phone work on ATT and or Cricket? Is it a GSM phone? Will it get 4G if so? Thanks!!!

i have the mix on Cricket since December, it's on H+ most of the time and some times 4g depends on your location I guess, so it works on cricket and I'm not complaining on internet speed

I use it on Straight Talk (the AT&T sim). I live in Springfield Missouri and normally get LTE everywhere I go. The only real issue I have is when I do happen to lose LTE (receive/make a phone call, lose LTE in one particular room at my work, etc) it will stay on H+/3G until I go into settings and toggle between 3G then back to LTE again. Sucks, but not that big a deal since Straight Talk basically caps speed around 7-10 megs and H+/3G pretty much handles that speed anyway. But I haven't really had that many issues.

Mine is on Cricket and running fine in the Des Moines, IA area. I have a few hiccups here and there, but nothing drastic.

I have it with Att and works great always on Lte (tucson,Az). I get the hd voice and video calling as well. Only complain is I cant wait for mix 2 lol.

Straight talk ATT sim LTE all the time I live south of Chicago
