I'm not sure if this is a network issue or a phone issue. I just got a replacement phone from Google. Popped in my sim 2 days ago and it was working fine, OTA 4.4.4 updated the same day. Came to work today and it was working for about an hour, and now it says there is no connection. I go to the "network operators" list and I only see ATT on there, which doesn't work for me since I'm on T-mobile. Other people in my building have T-mobile too and their phones work just fine, so I'm guessing it's not a tower issue.
I've tried restarting the phone as well as taking the sim out and reinserting it. Anything else I can try?
Phone is stock, not rooted, not flashed with a new rom.

My MyTouch 4G slide has been sitting for a month or two after previously working fine. Now it powers up however it can't get a signal with my T-mobile SIM (or my wife's). I'm concerned that somehow the radio might have gotten fried. So far I've reflashed it back to stock, unrooted, and hard reset it a few times, nothing has worked.
If I go into Wireless & Networks, drop down to Mobile Networks, Then Network Operators, and "Search Networks", it takes a few moments and finds AT&T & T-Mobile (I'm in an area where my devices normally get full T-Mobile service). However when I try to connect to T-Mobile, I get a message saying "Your SIM card does not allow a connection to this network". Same SIM works fine in a G2, connected to T-Mobile.
Anyone have a way to test the phone radio, or perhaps have an idea on what it's issue is?
I have had this exact problem, and attempted the same solutions, but without success. Was working fine, and then 1hr later quit working and was not able to repair even after return to stock/deroot, etc. Doing warranted return, and just got replacement phone by mail for swap out from t-mo.
am a little worried about reroot and rerom in case I have another problem.
My device is doing the same thing. Not sure when it started... I havent used the MT4GS in a few weeks, picked it up and reset it back to stock everything, and it's not getting any service from any of my SIM cards. I unlocked it a while ago to use on AT&T prepaid SIM, and not even that will work... Any advice would be helpful...

I've used Z-Device Test by Zausan Innovacion Tecnologica to test just about everything on my phone.
I'm having a similar issue on mine after trying jupoeanutbear and failing. I have signal but data craps out at random times now.

My phone HATES my SIM CARD, First off i rooted my phone, its fully unlocked and has been just fine for over a month. I'm using FIDO but its an unlocked Rogers phone. (SGH-I727R model) and original FW and everything. made a couple of phone calls in the morning and the when i got home i noticed that my phone displayed "unregistured SIM" so i tried reloading sim card, reboot and so on over and over again. and it didnt work. so put the sim card in my 4year old phone, and it worked.
try calling fido aswell as rogers.. they said, sim card might be old and there is a conflict with the NEW phone. so i went to futureshop talked with the dude got the NEW sim card and tested it out with no success. again tried it with old phone, WORKS..
now you think maybe the phone might be locked somehow... NOPE. i even tried dude's sim card and he is on another network. (NOT rogers or fido) WORKED with his sim, proof my phone is totally unlocked to any carrier.
NEW SIM Card Doesnt work with my phone but worked perfectly with buddies SIM CARD on another carrier?!?!... lol
and now it shows "no service"
PLEASE HELP.
Update
i have just formatted, cleared cache and factory reset and it still says the same ****. no service... anyone help? i'm dead in the water here..
I had the same problem, I had to switch carriers then my phone started working properly, Honestly I think its the company...
Update
well, it looks like i hit rock bottom. i even installed the new ics rom and its still doesn't take my SIM card. I'm pissed. i need to dump this phone and get a working one. I can't switch over to rogers, I hate them. and when i go on vacation this phone will be a brick if i cant insert everyone elses sim cards around the world.
and i dont think its the company's fault. i have a feeling its because its rooted or something along those lines.
maybe i will wait for the new galaxy sIII and dump this ****. $$560 wasted. i feel soo stupid for getting this phone.
hi,
What have you used to unlock sgh-i727? I have one and need to unlock it so can switch to other provider then ATT.
when i bought the phone it came unlocked. you must goto a website and give them your imei # that is on your phone. and they will sned you a unlock code upto 2 hours later.. DONT try and guess the code. and you will have to pay a fee but it will be minimal. $3-10
Final UPDATE, i went to rogers and got the phone on a contract for $50 and now i think i will give this to my mother to use for pics and ****. i have not a clue what to do with this thing.
And now it works
How reliable is that, i went out and bought a second phone from rogers and after a couple of days of my old phone not working with any sim card, Now it works with both rogers and Fido. Now i am stuck in a 3yr contract and have 2 of these phones. anyways i will try and get rid of my stupid contract. its only been a couple of days and "buyers remorse" law states that you can get out of any contract within 15 days of when the contract was signed.
Same Here
Strange - I had the EXACT same thing happen to me as well. Funny thing is it happened the same day as your first post about this issue on Jan. 25. I am on FIDO as well and had a working, unlocked i727R I bought off eBay from Basatne Electronics.
It was unrooted and working perfectly for a month and a half. All of a sudden I got ‘no service’ and sometimes ‘unregistered sim’ when I rebooted. I tried 6 different sim cards from FIDO and Rogers that worked on other phones and same thing. I cleared cache and did a reset. Same thing. I brought it to FIDO and Rogers and tried their demo sim cards in it. Same thing.
Finally I called Samsung to sent it back to them for ‘repair’. They sent me a UPS label and I sent it to Service Absolut, Samsung’s repair subcontractor in Montreal. It was there for over a week now. Their communication is terrible – it just says ‘open’ or ‘close’ on Samsung’s tracking website, so I called Absolut themselves yesterday asking for the status/tracking number. They said they were going to ship it yesterday even though my repair ticket online said ‘close’ since last wednesday.
I find this really strange, especially since your phone seems to have done the same thing as mine right around the same time. I figure it was Rogers/Fido that messed up their network somehow. Two working Rogers sims didn’t work in it either. My sim card was working on my old blackberry still. My IMEI didn’t appear in any blocked IMEI lists I looked up.
I just got my phone back today 10 minutes ago and it works again. It says 'full software upgrade and reset' on the repair list I got back, although I didn't mod my phone in the first place. At least I had my backup blackberry. Still pisses me off – I spent hours trying to figure out what was wrong with it and I wiped all my apps when I did a reset, so I’ll have to load them all up again and set up my phone.
Just weird.
And Again...
Well, it seems it just happened again.
After a month and a week or two of working perfectly (same length of time as last time), my i727R now says 'No Service' again for some reason on FIDO network and won't connect to anything except through Wifi.
I didn't install any new software or change any settings when it happened.
It was working one minute, put it in my pocket and a couple minutes later it says 'No Service', even though I have always had service before in the area I am in right now.
Does anyone have a clue what can be causing this?
Network, Software (some kind of timer somewhere that would shut off connection), Malware?
This is driving me nuts - I don't want to have to send it back to Samsung again.
Last time Samsung said they reflashed the software when I sent it back.
I don't know why I would need to do that since it was working just fine and I wasn't messing around with any settings before it started saying 'No Service' - same thing happened last time.
Hi,
Been with Straight Talk since August 2014 with this phone. No problems until 2 weeks ago when my service suddenly stopped. They replaced the SIM card, and it still doesn't work. Everything is fine on their end, they suggested it might be a phone issue. Anyone else have this problem, or does anyone know what I can do to fix it? Phone works great otherwise on wifi. It recognizes local cell networks, it just won't connect, even when I try it manually. Thanks!
Has anyone had this error message with their Z3? I have searched the web, and all that I can find is that Tmo needs to send an update to the phone to fix. Called customer service, waited for the update, restarted phone, and nothing. They then said to switch out the SIM card, and that did nothing either. Any others?
Yup, the same exact problem, they sent a sim update, new sim card, hell I even had them send me a new phone. Same thing. E911 is also set up correctly, lol they know where to send the bill. My daughters all have the one touch fierce and their WiFi calling works perfectly. My wife's m8 also works fine. What's the freaking problem.
I had that for a day and it dissapeared, my dad's M8 had it too and it went away somehow in a day or two.
This has been going on for 2 weeks now and no one seems to have an answer
I guess mine was slightly different.
Apparently TMO has to send you an OTA update. Also make sure its enabled in services in your MyTmobile account under services if not just tick the box and enable it.

I bought my mother-in-law this same phone (as I already have the D6616). Her phone had the same problem as you. Took me awhile to figure what happened, but like others have said, you need to contact T-Mobile and give them the error code. (I did this over T-Mobile chat) They in turn will push out a quick OTA update (can take up to two hours). Bad thing is I never received notification that it had updated, and I even asked the T-Mobile rep if I will see the update, and she stated yes. So, after two hours, and you still don't see the update, go ahead and restart your device. Once it reboots, your wifi calling feature will be updated and will then work. Oh, MAKE SURE YOUR WIFI IS TURNED OFF and WIFI CALLING IS TURNED OFF AS WELL! Your device will not update if you are not on the T-Mobile cellular network (as needed to push out the OTA). Be sure to turn on wifi calling once phone restarts and then you’re free to also turn on wifi.

U need to setup "e911" information with your service provider.
I've got a Verizon HTC M8 running DigitalHigh GPE 5.0.1 12/21 build, stock kernel.
I've had 4g issues with the phone since the first time I ever flashed away from stock. And the whole RUU back to stock and factory reset thing has never worked for me. The phone simply refuses to stay connected to 4G...
The first time I had the issue and I couldn't resolve it I called Verizon. Was sent through to tech support, who "opened a ticket" and told me I would hear from them once it was resolved. Never heard from them, but the issue did go away on it's own and the phone connected to LTE once more on its own. I was running BoneStock ROM at the time (this was back in August 2014).
Fast forward to November and I decide to switch to GPE and I start seeing 4G issues again. My phone would connect to LTE at first boot but once my Sim "activated" it would only connect to 3G from there out. I tried everything to get it back. I did RUU back to stock and factory reset, I flashed new radios, etc...
Finally I activated a new SIM that I had laying around and BAM! LTE service again.
... For a few days. And then back to 3G only.
I used an app called 4G switcher to force my phone to connect to a 4G signal and when I did that it showed that I was roaming... So I would dial *226 and update my roaming list and it would no longer say I'm roaming and would say I'm connected to LTE... For about 10 minutes and then back to 3G only.
I went to the Verizon. Wireless store today and they gave me a new sim and told me to call prepay customer service to see if I can get a warranty replacement. The new SIM instantly connected to LTE and has been connected for almost 6 hours now.
Is there something wrong with my phone that it keeps frying the SIM or could there be an issue with my account on Verizon's end, maybe something telling it to reprogram my SIM to not connect to 4g?
I have used my phone overseas for a month with a European SIM and a service that was only 3G, not sure if that would be relevant at all.
I'm fairly sure your problems aren't on Verizon's side. From reading over the thread, the GPE ROM certainly appears to cause some folks issues regarding LTE service. GPE wasn't designed to run on Verizon. It might be a good idea to stick with something built from a Verizon ROM.
Its a Lollipop thing. Happens on gpe, and Aosp 5.0 ROMs. Just wait till official gets out and they should figure out a fix.
