Hi everyone,
My carrier band is supported on the Mix namely B3 and B7. However, it is not possible to get 4G signal at all on the phone, only 3G.
Any suggestions?
Thanks

Settings/SIM card/preferred network
Or maybe you need to setup APN manually.

Thanks for the suggestions but I have tried that to no avail. I install the LTE discovery app and there is no LTE signal at all.
I also tried flashing the modem file from China dev rom but it is also the same.

So your old phone worked ok? Can you try a different carrier SIM card to check.
What carrier are you on and what are your APN settings?

I'm in Singapore and my carrier is Starhub. The apn settings are auto created and I double checked against other phone it is the same settings.
There is an issue with the latest update that causes the device not to connect to LTE. According to the official forum, it should be fixed in the next update, which is about a week away.
Edit: Some have suggested reflashing your ROM and doing a factory reset as well. Most of what I have seen points to the developer ROM. If you are using the developer ROM, then flashing back to the Chinese Stable and factory resetting the device should solve it. If you are using a vendor ROM, the same is recommended.
Just an update to anyone facing the same issue. This is a bug on the development rom and hence it affects all eu / custom rom that derive from there. Once flash onto the latest stable will resolve this issue.

Hello all,
As always, apologies in advanced if the solution ends up being simple, or that I've obviously overlooked something.
I have a Sprint HTC One. I live in Europe so I have rooted my device and also performed a SIM Unlock.
I was successful and the phone recognized my 3 Network SIM and works fine.
I have tried several different ROMs recently (Cyanogenmod, Carbon, Viper and Paranoid Android) and in each of them I cannot get the phone to switch networks away from SPRINT.
I switch the Network mode to GSM/WCDMA and double check in the phone info menu (*#*#4636#*#*). Reboot, and still no luck.
Oddly, I sometimes receive messages to my phone, but I cannot send any and there are no APN settings whatsoever.
It is necessary to be on stock to perform the SIM Unlock, so does that mean it will not work when I flash new roms?
Is there a setting in Paranoid Android (for example) that I am overlooking?
Thanks.

Thanks for the reply.
Are there custom ROMs for m7spr that could support GSM? Or is it completely non existent?
I have tried stock for several months and would rather not go back.

One of the threads mentioned that you need to be on 1.29 to use sim unlock.
It works for me in Bangalore, India so should definitely work for you as well...you might have to downgrade...
I'm on Viper 1.1.0.

By 1.29 are you referring to the Stock version?
I have successfully SIM unlocked, but all the ROMs tried simply do not pick up a signal.
I will try Viper 1.1.0, perhaps I used a known incompatible version beforehand.
Thanks for your reply.

I am still having trouble connecting.
Can I ask what you did when setting up, did the ROM automatically connect you to your network?

Do you get the message "Switch to global mode" when you rebooted your phone? You have to select Yes to that for the network to be detected.

I was able to use the ViperBoy ROM to stay on GSM with the advent of 4.3 official release I am wondering if the newer ROMS based the Sprint release will cater to GSM w/data cause its quite a bother not benefiting from the other perks
I'm using the "Stock with Goodies" ROM successfully on Vodafone in Spain. The OP is mentioning all AOSP rom's that don't work with a SIM card. Any sense based ROM will work(such as Viper). The only AOSP type ROM that I managed to pick up any signal on was the GE Nocturnal ROM after flashing this zip, https://mega.co.nz/#!dgdmFQbb!ZXw8Q18FwMU0Xn_t3_Prp2dcd9Fn01pdR5s3Ha-_TaI . This GSM patch was very alpha, it had numerous telephony.db force closes and disconnects frequently. The DEV for GEnocturnal said he would try to make the next 4.3 based GE rom internationally compatible so that's our best hope for using stock Android as of yet.
There's a guy using the CM 10.2 rom I built in the android dev forum. I don't know how it's working but it's working for him. He has voice and h+ Data just the signal bars don't show the correct signal.

Hi, Im from Mexico and my note 3 uses a 4glte sim card for Telcel company with my plan, its suposed to work the att version here (1700MHz and 2100MHz) but my smartphone only shows "4g" (+HSPA) even in the areas with lte's support. I even tried many things on the hidden menu *#*#4636#*#* but nothing works even if I choose the lte option.
My note 3 info:
SM-N900A
Android 4.4.2
N900AUCUCN2
Custom rom dynamic kat 6.1
Please help me! Greetings from Mexico!
Don't gona appears "LTE" if your custom ROM use "4G". But no worries 4G/LTE are same thing. You can install this MOD for Xposed anyway and try. Good luck :highfive:
Thanks my friend but I´ve made many tests and I only get +hspa speed, never LTE, I dont what to do

I think you just need to add telcel APN in Settings/Connections/More Networks/Mobile Networks/Access Point Names
Nombre: telcel
APN: internet.itelcel.com
Found here https://www.youtube.com/watch?v=I-N-atXwP_w hopefully that works for you and you won't have to reflash!

Hi. I'm currently on CM12 and I have been facing this problem(?) for a while now. Back when I was on stock 4.4.2, most of the time my phone is stuck on EDGE when I'm using my primary sim card (network A). In order to get 3G/4G signal, I have to explicitly choose a network operator. After a while, it reverts back to EDGE so I have to do that again. However, using my other sim (network B) doesn't have this problem. Now that I'm on CM12, I'm still facing the same issue. I can't use that fix since I think there's a problem with the rom itself when choosing the network. I'm thinking either this is a network error or a problem with the modem itself. I'm currently on NF1 and I'm wondering how to upgrade my modem to the latest one. Thanks!
Why switch modem if you think it's an issue with ROM?
Prerequisites to CM say nothing which modem you must have or that any of them are not good. CM don't change either bootloader, GSM or LTE modem.
CM provide RIL to communicate with modems.
QualComm based CM hasn't been able to manually search carrier since Aug 2014 https://jira.cyanogenmod.org/browse/CYAN-4902 and perhaps the decision to de-unify S4 CM can resolve this for Lollipop within a time frame of 3 months. [emoji12]
Please inform if you can find any chance log of what's fixed for different modem versions.

As I've said, this issue is also present when I was still on touchwiz/stock rom. And as you said, CM doesn't change the modem so the issue might be with the modem itself so I'm planning on upgrading to the latest one. Problem is, I don't know how to.
Just to be clear, I'm on EDGE most of the time on Network A on both CM12 and stock touchwiz rom. On Network B, I normally get HSPA+.

You should use the modem based on the country that you are using the phone as the bands available in each country and those included in the modem differ else you may have network issues, for more info refer to this post

Thank you! One question though, should I flash NI1_AUT_wifi_150107.zip as well? I'm not sure if that only applies if I'm on the WizCyan rom.
Just in case something wrong happens, if I go back to the stock rom using odin, will it revert back to the original modem?

Yes, the zip file applies to WizCyan ROM.
If you flash firmware the modem is included so yes it will revert to the modem in the firmware

Thank you so much! Will update if it works.
Edit: Successfully flashed the modem but I'm still stuck on EDGE. Oh well. At this point I don't what's the problem; is it my phone or the network?

Hi members!
I own an officially unlocked SM-N910T mobile (updated to latest MM 6.0.1) and currently using it in India. I can use 4g LTE for data but VoLTE doesn't work on my phone.
My network operator JIO provides LTE/VoLTE on Band 3, 5 and 40. I have enabled VoLTE from Settings > Calls > Call settings but no joy
VoLTE is enabled on my SIM and I can use it on another mobile.
I have been trying to understand what could be the issue over last 2 weeks but without any satisfactory answer from anyone.
So, I am wondering:
1. Is it because I don't have Indian CSC on my T-mobile phone? Is it even possible to flash Indian CSC on this device?
2. Is it because my device IMEI is 'NOT -INDIAN IMEI" and hence not supported? Customer care gives me more confusing answers - sometimes they say my phone is compatible for VoLTE and some say only Indian devices are supported.
3. Is something still locked to TMOBILE even after the official unlock?
Any answers are really appreciated from the any of you!
Cheers and thanks in advance!

After RAM Rom installation you can flash INU CSC, Dr Ketan uploaded it in some threads which i forgot.
for IMS apn , you simply create new APN with name and type as IMS and save it. It may not be listed or need not be selected in APNs list. but you could see the VoLTE in status bar after creating it. Also ensure that you create jionet APN first to get LTE access instead of using default jio APN settings.

Hey guys,
I bought an used Mi Mix and can't get LTE te work, band 7 (2600) which is used by my provider and should be supported on the Mix. When i'm in the center of Amsterdam, where i always had LTE with my Redmi note 3, it stays on H+, never ever does it switch to LTE, even if i force it to (xposed module). I changed the tcp/ip to ipv4 in APN settings (and switched between ipv4/ipv6 etc between roaming and normal), notinh helps..
I've read that it is possible to "upgrade" the modem/baseband but I can't find where i read that and/or if it helps. Do you guys have any idea?
I'm at Epic Rom 7.11.2 with twrp and xposed.
Thanks in advance,
Don

Need a new SIM mate, this my answer to everything. Can say it's probably ROM related or cernol
It's modem/baseband driver problem. A while back there were some issues with those. Updating or installing EU Tom doesn't update the modem drivers, an official fastboot flashed ROM does..
Some modem drivers (Indian phones I thought) don't support 4g for some reason, only 3g/HSDPA+. Either one can be solved by installing official ROM. Sadly you have to unlock bootloader again etc.

But you don't have to unlock bootloader again as long as you uncheck relocked bootloader, Twrp install again yes
I probably accidentally locked the bootloader..
