So I've been unlocked on Sprint galaxy s8 plus Sm-G955U and switched to MetroPCS. I flashed this root firmware from this forum for root. https://forum.xda-developers.com/ga...root-g955u-g955u1-snapdragon-sampwnd-t3658911 . Did the mps code. My service was working had to reset my network many times but I had service. Now for about three days I get emergency calls only in top left corner . I try to make a call and it says not registered to network. I have signal bars . My number reads. My sim is working in different phone. I checked my imei number it's original. I tried air plane mode , LTE to 3g/2g, checked a website to to see I was blacklisted it was clean. I switched firmwares. My voicemail pops up when I insert my card but I can't call it. Tried MetroPCS US LTE and MetroPCS apn can't connect to t mobile network operators. I'm lost. Is there a repair network for this device? Does anyone know how to get my MetroPCS service working again or why it's saying emergency calls only and I can't register to a network? Please help. I checked blacklist because I bought this phone someone and thought maybe that was the problem. https://imei24.com/blacklist_check/

Can anyone help me please?
If reflashing the firmware didn't help, you may need to search for someone to use a box to repair your network. A quick Google search showed me that there are options available. Just search "repair network SM-G955U"
Good luck!

Hi Guys,
My friend has asked me for some help with his x10i.
He's purchased it from a market, and it was locked to T-mobile.
Its since been network unlocked by a local store, in theory to allow use of any network sim card.
However when you boot the phone with a sim card in, it comes up on the notification bar
"Phone Not Allowed MM#6"
It will show the little signal bar full.
Checking phone status it shows
Service state - In service
Mobile Network State Disconnected.
It appears to register onto a network, be that orange o2 ect.
But we are unable to make outbound calls, receive calls.
Yet browsing via gprs is working.
I have checked the IMEI with the T mobile. They advised that the phone is clean and not barred.
I have Tried different Sim cards i know are working.
I have Flashed the Firmware back to Stock, Tried the Latest Firm and a few other different combinations.
I am now Stuck.
Any suggestions?
Thank you
Bump......?

did u try calling the network provider your sim card is with? they usually may have to program the network with imei number of the phone
u can also try going to network settings, search networks and choose the one u r on.
Woke up this morning with everything working. Got out of bed and place my phone on my desk and turned on my computer. I then looked back at my phone to see i had not service. Confused, i restarted my phone to see if that worked and it didnt. I tried another sim and it didnt work either. i then put both of the sims in a iphone and it worked there. I restored the phone to stock and 2 other roms and it still isnt working. The weird part is when on stock i get signal bars even when their is no sim. When i try to dial out i get "Not Registered on Network"
Any help is great help
Wrong section, ask in the general or Q&A.

Have you checked your Settings? Still got IMEI? ([Settings] [About Phone] [Status]) Phone connected to correct Network Operator? Access Point Names has correct data in it? [Settings] [More Settings] [Mobile Neworks]
Thanks for the responses. I had a rom running on it for a little bit over a week and didnt make any changes since. I also do have an Imei and an apn

It doesnt even show my network operator, thats the weird part it only shows rogers and when i put a sim in for fido (Rogers>Fido) i got service but no h+ even with the correct apn i only got edge
My Network operator doesn't show as a normal either - I do a Search and get (after a wait) Telstra, Optus and Voda - choose Telstra and it pops up a 'Registered on Network' msg.

yeah when i search i only get rogers???? This is the single most awkward thing ive ever seen
EDITTZ Found the problem. The phone switched itself to only look for one band not all. +_+ dont know how it got their and how it pertained through all the wipes but got it working DDDDDDDD
i had the same very exact problem..and yes when its in auto mode it only detects gsm signal so the data is slow signal is E.
i usually use the wcdma only option so that the phone on searches for 3g h and h+ but now when i select that option it only gives me
not registered on network..and no data signal at all.. and also the weird thing is that there is a signal bar on it plus when i scan for
network it searches the other two carrier brand on our country not the sims own carrier. help anyone

Hey xTristinx, glad you got your phone working.
I have the same problem on my Galaxy S, my SIM wouldn't register a network on it but it worked on a different phone. My Galaxy S still gets a signal but always says "out of service". I think this might be a problem because my friend used his SIM card in my phone and it f***** up the bands. Could you give me any suggestions on how you fixed your problem?
Thank you.
Hey guys
my SGS3 GTi9300 suddenly does not detect any mobile network. I cannot make or recieve any calls :crying::crying:
I have tried using a different sim card and same issue. No Service.
My sim card in a different phone works properly.
Manual searching of the network does not work.
reboot, airplane etc does not work.
My IMEI and everything is proper I havent made any changes in the phone. A very Spontaneous problem.
everything else works fine. wifi bluetooth etc.
I am from India on LiquidSmooth v3.2 rom. Android 4.4.4.
Network provider Reliance.
Please help
Try a different modem.
The one you WAS using will work but do you know what one it was or have a back up of it? I'm from the UK so I don't know what modem you would use. Also check apns as this happens with that to. All this fails go back to stock and test. If that is still a fail it time to check if imei is blocked by provider . I belive India networks now block imei that have been reported.
Solution
Surprisingly changing the network mode from 3g to 2g worked. Now I have network.
My service provider sent me the settings again maybe they got deleted or something.
Hello. I have an SM-G925F which I bought from Telekom Macedonia and I am still using my number from there also but I am currently in the US and would like to use it on T-Mobile USA.
I know that the device supports all the same bands as the SM-G925T model.
The problem I am having is that when my phone is set to LTE/WCDMA/GSM in the Network Mode settings, I do not have any data connection at all, only when I make a call, I start to get a data connection but only 3G/H+. If I switch my setting to WCDMA/GSM, then I get a data connection at all times like normal but it still is only 3G/H+. I have tried two different APNs and different settings in the APN but I still cannot get a data connection at all times on the LTE/WCDMA/GSM setting and I cannot get LTE/4G at all.
After contacting T-Mobile, all they came up with is to try to have the same software reinstalled on my phone. Does anyone have any experience with this and can anyone help me?
Anyone?
Call Tmobile and have them input your phone's IMEI in their system. Ask for the APN settings as well. I am on the same boat and one call to ATT got me from H to 4G. Your phone will just show 4G, not LTE but you will get LTE speeds regardless.
I tried doing that too. I called T-Mobile a few times and they confirmed my IMEI number being on the account but still no luck. It's really weird..sometimes I get 3G/H+ on the "LTE/WCDMA/GSM (auto connect)" network mode setting on the phone but most of the time, I get NO DATA connection at all..only the signal bars.
Any Update
Did you finally figure it out? Is LTE working now?
Alright, so here's the problem:
I've had my Samsung Galaxy S6 Edge for around 4months now, having no problems with it what-so-ever.
The other day (Tuesday) having waking up, my mobile wasn't able to send or receive phone calls or SMS messages, but it was still connected to my providers internet.
I can still browse the web using my provider, giffgaff, under 4G internet but when I try to send a text or phone anyone it says: "Not registered on Network".
I've contacted my network provider and they are adamant it's nothing to do with my network, also tried my sim in another phone and it works.
Now, I checked my IMEI and it was unblocked.
Tried rooting, factory resetting my phone and putting different roms on, nothing seems to be working. My internet still works on my phone, just my network is unable to connect.
When I manually search for network I find: Vodaphone, O2, EE, 3 Network. Having tried to load it up on O2 (Giffgaff uses O2 and my network provider asked me to do so) it says it's unable to connect.
I'm just wondering, is there anyway to resolve this?
Also, my signal bar is full, and the local reception for my Network is "excellent".
Hello, i've been having the same problem and couldn't resolve this with my network provider aswell i can get connected to the network but soon as it registers to 3g it kicks me of my network operator the only temp fix i could find was go to settings, mobile networks, network mode, gsm only, then register to network to receive and send calls and texts, i've tryed everything and it's the only thing i can suggest as a temp fix .:good:
