Thought I'd post my experience on here just because I know a lot of us are switching over and I must have gone through fifteen different threads to figure out how to get my data, talk, and text working. To start off I bought a T-Mobile nano sim and just plugged it straight into my droid thinking it would all be gravy...nope. This is exactly what I had to do: First, go into your mobile network settings and change to LTE/UTMS/GSM. Second, change your (Select Network) to GSM only. Third, create an APN that is as follows: NAME;T-Mobile, APN; epc. tmobile. com, MMSC; ht tp:// mms . msg. eng. t-mobile . com/mms/wapenc . APN Type; default, mms, supl APN Protocol; ip4/ip6. LEave everything else alone. trust me this is the most reliable way to go about doing the switch over and the data is fast, plenty fast. The phone info . apk app does work but for the ultra its not needed so don't worry with it. HAPPY SAVINGS all you DROID LOVERS.
Thanks for the help. I have unlimited Verizon with my bootloader unlocked, but I have issues with good service here where I live and work with Verizon. T-mobile may be better, so I am considering trying it out soon. I am going to test TMO for 7 days with their free program and see. If it works, I may just follow these directions and use my Droid Maxx.

I picked up a Droid Maxx XT1080M (Not the ultra, but they seem so.. similar....) which was unlocked.
I popped a NanoSIM into it, rebooted, and it took a minute but the device figured out to auto switch to the GSM/UMTS/LTE side of the baseband. After that the only thing I needed to do was add the T-Mobile LTE APN.
I'd check your APN and make sure it's on fast.t-mobile.com. From what I've noticed is that when I boot it up, and WIFI is off, if I am to start browsing it goes from E (edge) to H (HSPA) to LTE in about ... 2-3 minutes of browsing/using data. Then it sticks on LTE. This is not always the case as I've rebooted a few times tonight without it bumping down to EDGE.
Getting 43mbps down and 33 mbps up on LTE, and 6down/2up on UMTS/HSPA. In Seattle... This device hits the sweet spots for T-Mobile LTE bands with 1700/2100. We'll miss out on their 1900 build-out, but should still have HSPA+ on those other bands anyway.
One odd message I get after every reboot is The SIM card is from an unknown source. does not seem to affect anything. Anyone know if this is normal? I've not seen this error before on other unlocked devices.
I am on metro, I don't have that issues at all. I pop in Sim, did a apn n wallah 4g LTE n every work fine took me a hot minute to figure out how to get LTE to work.
The Sim car error is Cuz its a Verizon fone. It doesn't effect the fone at all. Once we get root n we get to flash I know we won't c that no more.

Sadly, my phone seems to have a borked radio.
What happened? So I popped in T-Mobile SIM card, and calling and texting is a charm. (Except for the Unknown SIM issue, of course.) I then found out that I was getting NO data after a factory reset. So then I looked to downgrade OS version, blah blah, flashed radio, did fastboot config carrier, so on and so forth. No joy. Sigh...

Verizon has changed something in the system part of the most recent ROMs to prevent t-mobile use. I had the same issues. For some, I could bypass the block by removing some of the CDMA references in build.prop. For the most recent Verizon ROM, nothing I tried worked.
Luckily, I am unlocked. Moved originally to a ported Moto X ROM, and then to CM12, and everything works fine there.
That's odd, I'm on the latest build and have 0 issues with Tmobile.
I just plugged my T-Mobile nano sim in last night and used the instructions on this thread and a few others around the internet to get T-Mobile 4GLTE or HSPA+ to work. I can text, make calls, and I get all the Edge (shown as an "E") data i want, but It is way to slow to be useful. I have tried it on both my droid maxx phones (one 2013 - 32gb, and one 2014 - 16gb). Both are on latest system version 24.3.7. Any other advice to make data work decent? I can get NO 4G or HSPA+
Does tmo say you have wcdma or LTE access where you are.
I am having the same issues after FDR and data wouldn't work anymore. In my area I am LTE so the droid ultra that worked well in the last 4 months on T-Mobile, I think it is a software problem.
Yes it is software problem. If you can get your phone rooted and bootloader unlocked then reflash the rom it works perfectly. I get LTE on tmobile on the CM rom no problem.
I run LTE just fine.. All I needed to do was add T-Mobiles APN to my phone..

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

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.

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!"

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...

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

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.

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?
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.

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.

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.......

I glad its working now, you can stay on 5.1.1 with the hybrid modem if you got the 4G signal, or return to 4.4.4 if you want. regards.

i think is real, speedtest results are much better using 4G. I got around 40mbps.

i just sintall LTEhybrid33-84 and EnableNexus4LTE with TWRP custome recovery, but apparently without any 4G signal, in the menu mobile networks only i can choose 2G & 3G.... but the baseband does change.....
so, i use the trick hidden menu with *#*#4636#*#* and i choose LTE only, only with this my nexus 4 has 4G signal¡¡¡¡¡¡ but, if i come back to mobile networks, again only i can see 2g and 3g and the little 4G on top disappear.... so i need to come back again to hidden menu....
conclusion, mobile networks menu it will prohibited for me :silly:

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.
I know this has other threads, but I wanted to post something that helped me get VoLTE working that none of the other threads addressed.
Quick background: new to TMobile, new to the 1+ brand. Rooted, stock. I could get LTE, but I kept getting kicked to roaming AT&T H+ or 3G, couldn't get VoLTE, and very slows speeds even when on LTE. Tried every APN combo, network settings reset, factory phone reset, tried every *#*#4636#*#* preferred network type...nothing. Chatted in to 1+ asking if I could speak to technical support. The response was the only way to fix it was to factory reset (which I had already done) and downgrade OOS. The newest OOS has the T-Mobile optimizations, so downgrading makes no sense! Needless to say, the whole 30 min chat was a waste of time and just a bunch of weak canned responses with no attempt to really help or figure out how to escalate me to someone with some knowledge of the APNs and settings needed.
Out of desperation, or since I had tried every other possible trick, I went under my T-Mobile SIM, Network Operators, and toggled Auto Choose and manually chose TMobile 4G.
Boom, full bands 4, 12 and VoLTE, and normal speeds! Carrier aggregation is even working sometimes.
I don't know why Auto Choose doesn't know how to grab 4G permanently, but everything is working!
Does anyone have any idea why this fixed it? Since I choose 4G, will I lose my ability to get 3G in rural areas? I don't feel like there was much info on how VoLTE is provisioned on the phone.
What's everyone's experience with the preferred network settings? I'm currently in LTE/UMTS, and I don't have the LTE/GSM option that apparently everyone else has...?
Also, does everyone else have as sporadic speeds as I do? One moment it'll be 40 down, next it'll be 6? I know it has to do with bands, but should there be a way to even that out a little?
Sidenote: I really like 1+ mentality about rooting and software, since I have to have a rooted phone, but this experience really soured my first impression. Plus their 1+5 is a major letdown to me. I don't think I'll purchase anymore 1+ products.
Feel free to correct any misinformation in my post.
I also have noticed when I try streaming, webpages or speedtests the little LTE+ carrier aggregation kicks in to combine band 4 and 12 and I get pretty good speeds. See screenshot
My speeds do definitely vary on Tmobiles network. Isn't an issue for me, everything streams fine, also i haven't had an issue with VOLTE since I got the phone in February..
I noticed when I'm in a roaming area, instead of roaming now, I completely lose service. I believe this is because I manually selected TMobile 4G as my operator instead of auto, which would allow the phone to jump to AT&T. Any ideas?
So still having problems, but only when traveling. If I have network operator on "auto" it'll select AT&T roaming, but then it'll just stick then and never switch back to TMobile, even in full strength band 4 or 12 areas. I have to reboot, and toggle auto for it to grab a T-Mobile signal. Very irritating. This also kicks the phone off VoLTE, and I've yet to get it back. Not sure if this is TMobile or the phone's fault. Tried everything I can think of. Any ideas?

Excuse my ignorance, but what would a new SIM accomplish, technically speaking that is?
FYI, my wife's HTC 10 does the same thing. That would make two bad SIMs unlikely?

I've had same problem as yours, I went to T-Mobile store and told them what was going on. They switched my SIM card and problem fixed. I was told because my SIM was too old (4 years at least) that's why i was having such issue.

Gotcha thanks, I'll give it a try! What's weird is our SIMs are only weeks old....

That's what I've been thru and got fixed. Hopefully it'll work for you too
New SIM, no change
This phone has the features I want, and T-Mobile has the speeds I want, but this is frustrating to be kicked to roaming and no VoLTE....

Sorry to hear that it didn't work out for you. I attached couple of screenshots just to show you that it's been working good for me after I switched SIM card.
Edit: have you tried to create a new APN instead of using the default APN?
Edit 2: I can show you my APN if you want
Sorry, must have not been clear. I can get LTE, just not automatically after going into a roaming area. It just sticks on AT&T roaming until I manually go back in and select TMobile 4G. The problem with that is when I do need roaming to work, it won't because I have TMobile 4G manually selected.
Another problem is that I can't get VoLTE to stay very long, in fact i haven't had it for a couple days, despite me being in a very strong LTE area.
I appreciate your help
Edit: yes, if I could see your APN that'd be great!

Just create a new APN exactly as mine and see if it works
Hmm yeah that's the one I have too....
Btw, maybe I just needed to wait,, but VoLTE is working again, and it's reporting the correct IMEI (it wasn't before but TMobile told me that wasn't a big deal...I beg to differ because now my TMobile app is working whereas before it wasn't) Fingers crossed the new SIM did the trick! I'll know tomorrow when I commute to work and it starts roaming whether it'll reacquire T-Mobile and VoLTE
Quick update: I definitely have noticed an improvement in jumping off AT&T roaming back onto TMobile LTE. AND VoLTE is now sticking. But... I'm inclined to think it's something related to me not having my second Verizon SIM in. I have a company work number on a Verizon SIM that enables me to text and call from that number. Obviously data doesn't work but that doesn't bother me since I have TMobile unlimited on my personal SIM. When I insert my Verizon SIM in the second slot, my IMEI number changes in the testing menu, but not my settings info! What the heck? The IMEI number identifies the phone and shouldn't change...I thought? Very confused why part of my phone retains the correct IMEI and the testing changes. I instantly lose VoLTE and my TMobile app fails to authenticate.
What is going on???
UPDATE:
I popped my Verizon SIM in again (slot 1) and it's reporting the xx...15 IMEI (correct one on my T-Mobile account) and the T-Mobile SIM (slot 2) then drops to xx...07! I'm so confused! I thought the IMEI is NOT supposed to change because it identifies the device?? The ICCID is the SIM number? Why is Verizon SIM screwing this up?
