Nexus 4 only work with at&t mexico, no other carrier - Nexus 4 Q&A, Help & Troubleshooting

Hi, i recently buy an used nexus 4 in ebay, simply for nostalgia, so, i´m in Mexico, the nexus 4 that i had 3 year ago, was unlocked, so, i supose this too, when arrive, i connect to wifi immediately without any sim inside, the cellphone request for one upgrade, i accept, after that, i put my sim from Virgin Mobile and the nexus only showed " no simcard inside, only emergency calls.... y try with other carrier, weex mexico (virgin and weex work in Movistar, they are OMV) and the same all.... finally y put a sim from at&t mexico, nothing... with the sim (att) inside, i downgrade to android 4.4.4, when woke up, the nexus 4 with the same result, No simcard, so, the cellphone wasn´t detecting any simcard, after that, it request for the next upgrade, lollipop 5.0.1 that i accept, but in this chance, the nexus with the simcard from ATT showing signal¡¡¡¡¡ the cellphone was working at 100%, i made a couple calls, without problems.
But, i try with the other 2 simcards, and it doesnt detecting, simply show again No simcard, emergency only, so i switch back my Att sim and this is detecting without problems....
I install a rom named Pure Nexus, waiting for work, but the same, only with ATT simcard work, so i downgrade again to 4.4.4 but in this chance with other simcard differnt from AT&T, Virgin mobile.... but nothing, nexus 4 is not detecting any other simcard than at&t¡¡¡¡¡¡
What can i try? could be a nexus 4 locked only for one carrier or what? in google dont appear in blacklist, the imei is good nor corrupted... could be the sim holding?

try going back to stock using the nexus 4 toolkit,then root, and try one of the hybrid models LTE enabler or download the 107-3, if that doesnt work also, then it might be defective.

use this to go back to stock
http://www.wugfresh.com/nrt/
you will get android 5.1.1, you can also install custom recovery and root using it.
then if the sims doesnt work, change the modem using the LTE Enabler you can get it from the Play Store.
it has the modem until version 104-33, but im using another one the 107-33 that i got from
https://drive.google.com/open?id=0B77BTW0zStYCZmpPR0xTaWE5OUU
104 33 and 107 33 are hybrid modems, but you can also install stock modems,
the modem is the one that allows you to make calls and use the data channel in your phone
hope that makes sense, let me know how it goes. regards.

well, i flash EnableNexus4LTE.zip and LTEhybrid33-84 without good news, i have the same issue, only at&t mexico sim is detected and the others no, well, i´m now with 4G LTE but only working in at&t
i don´t know what other things trying in the nexus, seem like only prefer at&t sim and no one else.
Adding information, i have sims from cricket USA and t-mobile USA, i know is not supported in México, but it will be for try to get something like: Sim not activated... or invalid sim, but other different from my nightmare: NO sim, please insert....

SOLVE:
I´ll auto answer... after a lot off attempts, i found the problem is the sim reader, like i posted before, only working with at&t Mexico sim, so, I watch the thickness of this was little bit smaller than others, my "strategy" was try to imitate the fact that at&t sim is making contact gently on pins, i take a 3in1 simcard, and i put the nano sim in micro sim adapter (included in the sim) but not in all (i don know exactly the words in english), so by this waya the nano sim standing on a little bit from microsim adapter.
when i insert the sim by this way an my nexus, and turn on, the cellphone recognize inmediatly the sim, so i found the key of this problem, like i said, the problem here is the sim reader, because, a normal and good sim reader not need this tricks to get signal.......

you should be able to select "LTE/GSM Auto" that way the phone will switch to GSM when needed.
and the option is only visible under *#*#4636#*#* menu, also, we have to switch to LTE/GSM auto, if the phone is restarted. there is a way to make it persistent, but I haven't tried. i'm fine with it since i don't restart the phone too often.
hope this helps, regards.

Nexus 4 - No Service with specific carrier

Hi,
I have Nexus 4 for about 3 months, and I was using it fine with my SIM cut as micro sim in my carrer.
On Friday night, I put it into airplane mode and went sleep. On the morning I disabled airplane mode but the carrier signal didn´t came back.
I tried then put my micro sim into another phone, and it worked fine. I other carrier micro sim in my phone (also cut from normal SIM) and it worked just fine !
I already tested 2 micro sim from my carrier and all of them gets the same, N4 says 'No Service | Carrier name' but with another carrier, it works fine (tested with 3 different micro sim, from this same other carrier).
I called to my carrier asking if there is something blocking my phone, but they say everything is fone every time. (Btw I discovered that my sim was blocked for some reason, but it is now unblocked - so I´m thinking if they did not blocked my IMEI, but they say no every time).
If I go to the Mobile Networks -> network operators and choose my carrier from the list, it says 'Selected network (XX) unavailable'. If I choose automatic, it does not give me any error, but the 'No Service' text...
I already tried factory reset, reboot, airplane mode, flashed google factory image, flashed radio .33, .48 and .54, flashed CM 10.2... nothing...
My question is, is any way, techinical way speaking, that my phone has 'broken' something that avoid me to use only a specific carrier? Because my carrier adivce me to take it to repair, as it is the guilt on the history, but I´m thinking it is very strange that it work for another carrier but mine...
Is that even possible ?
Thank for you help !

I'm having the same problem here, I've tried to flash back 4.2.2 ROM and then 4.3 stock but still no better. please any1 help us :crying:
Have you checked APN settings? I've seen it sometimes default to the wrong one if there's multiple in there. Who is your carrier?
It happens to be in my case, a problem with the carrier itself. I tried others SIMCard from same carrier, and got the same issue. Tried from a different carrier and worked just fine.
After a long fight if the carrier, I found out that my IMEI was on blacklist only for that carrier and after another long fight, I could get it unblocked and everything got back as normal...

They have a lot of reasons to do that. In my case I believe that the cause was my phone got stuck with something and start to consume a lot of 3g data. As my plan do not allow tethering, they identify this high usage as tethering and blocked both my simcard and my IMEI (even that at first they swear my IMEI was not blocked, but after I opened a ticket in government regulations, they fixed it).
If it works with 2 other carries, do not work with other sim cards from your carrier and in past it worked fine, it is 99% sure that your IMEI is blocked at the carrier, I would say

VS980 on GSM Question

I bought a VS980 (The Verizon G2) because they come unlocked and it was cheapest. I use Net10. The sim card works within the phone, however it constantly shows that i am roaming, i dont get hspa+ (4g) anymore. Also it shows the sim card icon with a question mark on it. Could i possibly flash AT&T firmware onto it to fix that? I mean, what could i do? What specific things would i need to change?
Thanks a lot!

i also face same problem always showing roming icon when i use any gsm sim card on it...
I have the VS980 and it works great on T-Mobile, I get GPRS, EDGE, 3G, HSPA+, and LTE. I never tried it with AT&T or another GSM provider though.
When you use the stock ROM it will have issues like you listed, however if you install another ROM it should work fine. I believe I was running Malladus 4.2.2 at the time which removed the ? icon, and I didn't have to enter any APN info. I also ran it when on a 4.4 AOSP ROM.
so do i have to downgrade the bootloader or what? I'm actually trying to get a verizon vs980 on cricket (aio wireless/at&t network) and can only get H speeds. not bad and i can stream HQ youtube videos without buffering but would like faster. any input?
I met this problem, too. Is there any solution so that I can get my 4G back?
Please help.

[Q] Phone stuck on 3g. have to force it to LTE>

Been running CM 10.2 nightlies for a few weeks and everything has been smooth except the phone is stuck on 3g. If I go into mobile networks and network mode it was set to "CDMA + LTE/EvDo". Tried "Global" and still the same thing. The only way I can get it to work is if I choose "LTE" (and I did confirm it was running at full LTE speeds) which then makes calling impossible.
Not sure what to do, have played around with APN's but haven't found anything that works yet.
Also, tried updating to the latest radio and that didn't help.
Any ideas?
Follow my thread . I just went through the same thing. Short answer: new sim card

I saw your thread but I don't understand how I would be able to get LTE service (through forcing by selecting LTE only) if my SIM card was somehow fried. You would think if it was a bad SIM it would be more than just that. Also, both our cards "failing" in the same way.
I do remember dialing *228 a while back as I was having some connection issues but can't remember if I saw LTE before doing that. Almost think its Verizon's way of sticking it to those that unlock and flash roms (when you *228 you have to come replace your sim and get "outed").

One possibility is if you ever messed with *#*#4636#*#* & did anything to 3 dot menu band, you can have a hosed radio partition. Rsd restore is only fix.
Vzw does indeed want us not rooted as (edit)a lot rooted users cause them BIG headaches.

Can't make calls when on LTE mode

I have n9005 rooted TouchWiz stock on 5.0,
when my phone is on LTE mode i'am unable to make/receive calls.
Kindly help me solve this problem.
Is the phone set to LTE only? If it is, does the carrier support VoLTE?

LTE/4G is a Data-Only network. To make calls over it your carrier needs to support Voice Over LTE, or VoLTE for short. Which is the mobile equivalent of VoIP.\
If your carrier does not support VoLTE, and your device is only allowed to access LTE, you can't make calls. Change to 'LTE/WCDMA (Auto)' (4G/3G) or 'LTE/WCDMA/GSM (Auto)' (4G/3G/2G) mode so the phone can automatically change to a network that supports voice codecs.

Not receiving incoming calls on AIRTEL 4G LTE
Iam facing peculiar problem with the phone. Need help with the problem.
I am using samsung note 3 LTE. When ever some one tries to call me, my mobile is Not reachable or out of coverage area even when my mobile is in my hand , perfectly working with the second sim. outgoing calls are working fine. Again, when I am in call, then if any one tries calling me, then I get call waiting. So incoming call waiting is working for me. But incoming calls are not able to connect. LTE data is working fine though incoming calls are not working. 
Tried the following but no luck. Problem still persists:
1. Reset phone and erase all data
2. Hard reset phone (volume down + poweroff and clear all data in drive)
3. Tried changing SIM to second slot
When I switch the sim back to 3G mode or 2g mode , incoming calls are working perfectly fine . I googled it and found that most people had same issue and was resolved on switching back to 3G or 2g . 
But I need to use 4g . Please tell me a solution.
I had that same issue until I took my note 3 to Rogers and they said that the note 3 doesn't support Lte
Your rom must support VoLTE.
I would unroot and go back to stock firmware, and see if problem still happens,? if it does ,its most likely the sim card.sd card reader slot, (flex cable),my Galaxy s4 had the similar symptoms , but LTE would work with a custom rom, but not if I used stock firmware, replacing sim card reader flex , just google your mak and model and search ebay. mine cost a few pounds for a decent quality part, so dont go rushing to buy the cheapest. No problems since replacing that part, even after resetting phone 3 times to see if it was a fluke. I know its a bit late for a reply, but this actually worked , I am 99% sure it would work for anyone else who has this problem with lte not connecting when 3G, and 2g do connect. If you have tried swapping sim cards, putting sim in another phone,, etc,etc. this part mentioned(sim card/sd card reader) is your culprit. Took me just over 5 hours of testing to find the solution. thanks and fair well android users
---------- Post added at 06:49 AM ---------- Previous post was at 06:24 AM ----------
For many people having issues with LTE not connecting and diverting to voicemail on android, I am here to offer a solution to your woes. I have a Samsung Galaxy S4, GT-I9505, and recently in in 2018 in July, I had the same problem, phone calls connected on Gsm, Wdcma, BUT when I tried LTe mode, NOTHING, WENT STRAIGHT TO VOICEMAIL.Anyway I tried almost everything mentioned on certain websites and forums, with some luck, Changing LTE mode to GSM worked, and I could receive and hear phone calls. So I investigated further, I tried re flashing stock firmware, factory resetting phone.(nothing worked). I then rooted my phone and flashed a custom rom (do not try this) as it could damage your device if flashed wrongly. Yeah, so I flashed a custom rom, and low and behold problem disappeared, so I used my phone on LTE for 2 days, with no problems, I then decided to go bacjk to stock firmware, ...problem came back, not connecting to LTE mode..........being as patient as I can be, never gave up, and had a spare phone which was dead, just laying in the drawer, ..so ,I took phone apart and thought, it must be where simcard contact make contact with sim card reader contacts ( broken sim card /sd card reader part, and was I wrong, no, it actually was the sim card reader part which coonects with th motherboard, Voila, I am 99% sure if anyone else has this problem with any android that has LTE capabilities, and you know its not the sim card, then try this fix first, MAKING SURE YOU GET SOMEONE YOU KNOW TO HELP YOU , IF YOU ARE UNSURE OF WHERE TO BUY AD HOW TO FIT. hope this has helped,and I know it is a long thread, but hopefully it will be a solution that works for whoever reads and trie this, over and out. yours in sincerity, Tech82, from Surrey, England.

Moto E xt1526 - use GSM SIM, going round and round

Greetings fellow telephony addicts - purchased a Boost Mobile Moto E w/5.1 (xt1526) because of apparent ease of ul'ing bl and rooting. True enough --
However since then I've been trying to get the device to allow use of a GSM SIM (USA/att.) Recently did it on a vzw (xt1528) no problem following instructions found here bit the xt1526 has beaten me senseless, going so far as to install cm13 in a totally illogical move. It works beautifuly, if you don't need calls or mms. Searched the crap out of the E forums with a couple of tips that did not pan out.
Anyone give me any hints /tips or even a nay as in "you dummy you can't to that!"
TIA,

Boost / sprint xt1526 are locked so that us domestic GSM Sims are not recognized. To my knowledge, no one here has yet gotten around this. I switched from a sprint branded one to a USCellular, which is fully SIM unlocked out of the box, bootloader unlockable, and supports att LTE. Using it right now with my postpaid ATT SIM

Only thing I can think of is to flash the RADIO from a variant that isn't SIM locked and seeing if that works. It's a risky experiment tho... it could definitely brick the device in terms of ever being able to connect to a cell tower again.
Closest match is the USC 5.1 stock ROM's radio, which has the same model number XT1526, and is CDMA compatible, but that phone is also known to work on domestic GSM networks.
Double Thanks - Phone is useless to me as is so it's worth a go. Will report the results here.

Weird - I installed the complete USC 5.1 stock ROM - Everything seems to work fine, but the system version and the broadband version coming up as Sprint. US cellular is not a Sprint MVNO I don't think, but it seems to be kind of a hybrid in terms of networks? No option for switching the network to GSM/LTE in the settings that I can find.
Not sure what I'm going to try next...

Weird - I installed the complete USC 5.1 stock ROM - Everything seems to work fine, but the system version and the broadband version coming up as Sprint. US cellular is not a Sprint MVNO I don't think, but it seems to be kind of a hybrid in terms of networks? No option for switching the network to GSM/LTE in the settings that I can find.
Not sure what I'm going to try next...

Did you flash the Radio/Modem too? If not, that's why the baseband comes up as Sprint.
Dial *#*#4636#*#*, phone info, change "CDMA/LTE" to "LTE/GSM/CDMA auto (PRL)". If you can't do that, follow the 5.1 instructions here: http://forum.xda-developers.com/moto-e-2015/general/how-to-verizon-moto-e-2015-gsm-network-t3098953 (change the 9 to a 10 for LTE/GSM/CDMA)
This will allow you to change the phone to LTE/GSM/CDMA mode.
Isn't the NON-HLOS.bin file the modem file? I did the keyboard commands and got the phone info and was able to change it but it didn't change anything, live or after a reboot - same thing. did the adb shell commands and the same
thing, cellular network settings grayed out. I put back the sprint SIM that came with the kit and it was fine and the network settings are available...hmmmm.
I greatly appreciate the suggestions. I'm gonna leave the battlefield and get dinner or my wife will call me mean geeky names

Putting this thread to rest
Spent the last couple of days flashing the E with rom after rom, particularly of GSM phones, ATT, TM, etc and their respective radio files. And not to my surprise the phone works fine with every one of then regardless of model XTxxxx anything, phone runs flawless, except for the network of course, which always remains Sprint.
I have to conclude, unless someone can prove otherwise, that the phone network part is either embedded in the chipset as hardware or a combination of hardware and software, or the modem files are somehow protected from being overwritten.
Was interesting and educational.
Thanks to those who gave ideas or suggestions, especially you Mr. President

Boost / sprint xt1526 are locked so that us domestic GSM Sims are not recognized. To my knowledge, no one here has yet gotten around this. I switched from a sprint branded one to a USCellular, which is fully SIM unlocked out of the box, bootloader unlockable, and supports att LTE. Using it right now with my postpaid ATT SIM

Ok –*question. If I put Cyanogenmod 13 (Lollipop) onto the Moto E 1526 (U.S. Cellular version) –*will GSM work on it? I need to buy my grandma a GSM phone who doesn't live in the States & I want the GSM card to be easy plug in play for her.
I know that the U.S. Cellular version is the best because it is unlocked for GSM as well, but I believe XT1526's default radio is CDMA.
Maybe I should get a GSM sim card here in the States and switch it to GSM on CM13 (if this is possible) –*that way all my grandmother has to do is put the sim card in without any hassle.

The device does do funky things with the radio on first boot on a new rom. I've run several CM based marshmallow roms. There's no real issue, but you need to go through the non-adb method (using the network app) to get GSM working on every new clean flash. Typically this means pulling the GSM SIM before initial boot (when I don't, the radio keeps cycling through modes making initial setup very difficult), do setup on Wi-Fi, turn off radio, insert SIM, then do the process.
I definitely would not give the device to a non tech savvy person before doing this on a clean flash. Once it's done, you can remove and reinsert Sims without issue.

Thanks for the info and advice. Much appreciated.
Btw, when you say turn off radio –*you mean by using network app right? And you'r ereferring to these instructions from: http://forum.xda-developers.com/moto-e-2015/general/help-confirm-5-1-how-to-verizon-moto-e-t3264258 ?: "Switch Sims
switch to settings -> cellular networks
Pull down notifications-> Airplane mode ON
Network App -> GSM / LTE (close app)
switch to settings
verify 4g (I always click on it, still shows CDMA)
NEtwrok app -> Turn on Radio
Settings -> click on CDMA -> Select 4G
Airplane Mode OFF"

Yep, you got it. Actually, I don't think it's too picky about the order of operations as described in that thread - I've done this many times without referring to the thread so have likely done it "wrong" at times, and it still works. Basically, radio off (either via airplane mode or network app), switch modes, radio back on.
Just don't clean flash a rom without either access to Wi-Fi, or a locally installable copy of the network app.

Hey .. i am in Karachi Pakistan ...
i have seen this phone workingperfectly with gsm network until someone makes a factory Data reset ..
still not found out the solution ..
the devices arrived from china in working condition ..
FYI - US Cellular was bought out by sprint last year, so they are now a sprint mvno.
Did you try flashing the stock 6.0 ROM?
