The phone says No service and has the little 'X' above the signal. It can't detect the sim either. I can't change IMEI either.
I have rooted the phone and have factory reset it before.
If you could tell me how to turn the Cell Radio on, that'd be great. (CDS Info says it's off)

ive been using the phone for a few weeks now and it was fine until today, i cant connect to the internet via edge . ive tweaked with all the settings but nothing seems to work. everything else is fine . ie i can make calls and send text's but i cant connect to the internet. i checked under the status and it shows the mobile network state is disconnected. i have no clue as to wat this is since im new to android.
pls help!
Have you turned MOBILE DATA off via the power on/off menu .
jje
ive checked that too.
Go to Settings- Wireless and Network- Mobile Networks- Access Point Names and see if the APN is ticked or not or the correct APN is ticked.
everything is back to normal again,it connected to the internet, by itself . must be a random bug in the os
problem solved. peace
I have experienced the same thing with my phone, except that it shows "activated". After a while it just started working again.
I've had the phone for a couple of months now and everything has worked fine till now, a little bugs here and there but no issues. A few weeks back (on android 2.3.3) I was unable to make or receive calls, but surprisingly was able to make text messages. I tried everything, turning flight mode on/off; the phone on/off; etc. I was on the verge of contacting Samsung but then suddenly the thing started working once I came back home from the office.
There has been no problems till then but today suddenly (now on android 2.3.6) the outgoing calls no longer work, same for outgoing text message; but I still get incoming calls and messages.
Just to be sure that this wasn't a SIM or service issue, I tried changing SIM's (different SIM did not work on the phone) and used my SIM on different phone (where it worked).
Also 3G doesn't work as well, but connection here is spotty so I wouldn't trust that. The only message I see different on the 'About Phone' tab is 'Mobile State-Disconnected'. I have full signal strength and all that.
My thoughts are that it was, or rather is a phone specific issue and would appreciate someone else's thoughts on the matter. As to my problem I assume it will sort itself out in a little while.
FYI: Samsung Galaxy S2; Android 2.3.6; NOT rooted; Indian version; On Airtel Mobile Network.
Mobile network state disconnected.
Hi guys, I have the same problem with my network connection also my 3g does not work anymore, I`m play with some secret codes like a ##72786# on my epic 4g touch sprint phone flashed to metro pcs and now I have no 3G service. In the setting menu under network status say Sprint. How can I get my 3g back?. The mobile net. 3G is on and the wifi is off. I need to change the network to metro pcs in the status setting and how can do that? Thanks for your help and sorry for my bad English.
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

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.
phone says no sim card and i don't have data, still able to use sms and phone calls when I'm around wifi even if wifi is turned off. In settings/status under service state it says voice: in service / Data: in service. Under cellular network state it says disconnected. It recognizes my network: sprint and my cellular network type : lte and my phone number as long as I'm around wifi even if it's turned off. As soon as I get out of range for wifi all of that data in settings/status is "unknown" until i find wifi again and reboot. Was told to call the carrier and get a PIN to unlock my sim card but it didn't work. Any help please?
Since you're in the Sprint forum, and there's no official Sprint Lollipop ROM, I assume you're running an unofficial AOSP ROM. If so, the traditional sprint fixes (update profile / PRL, for example) won't work. If you have a nandroid of an official Sprint ROM, you might try restoring to that, updating Profile & PRL, enter ##72786# in the dialer (the phone will reboot a couple of times--that's normal) and then reinstall the AOSP ROM.
That may not help, so I'd suggest asking in the thread for the ROM you're running.
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!
