I have an international unlocked GT-i9250 that seem to connect to any of the networks. It was working fine until I decided to flash a ROM.
I have tried various SIM cards of different networks. It seems to detect the SIM card though. When I pull down the notification drawer, it shows "Emergency Calls Only - Airtel". So it is able to recognize the Airtel SIM card inside. But it wont connect to the network at all, either automatically or manual selection.
When I manually search for networks and select the right network, it comes up with a message it wasnt able to connect to the network at that time.
I have flashed all the factory images starting from 4.0 to 4.3 and a couple of other custom ROMs and none of them seemed to have helped. I also tried extracting only the radio from the images and flashed them using fastboot and that was uselesss too.
EDIT: Yesterday, I flashed the stock ROM using Odin as well. Still no luck.
Is there anything else that I can try?
Nobody? :-/
Same Problem
I registered on the site just to say that I have the same problem .
my nexus 4 was working fine like 1 year untill we cut off our mobile carrier ,
now , when we enabled the carrier back on (sorry for my bad English , I hope u'll understand me)
the nexus 4 seems to recognize the sim since it writes : EMERGENCY CALLS ONLY | MY CARRIER (012 MOBILE)
but i cant get it to work with the sim , the sim works perfect on my moms iphone so its not a problem with the sim .
the sim wasnt cut or anything . and it was working just fine for 1 year . I tried flashing google stock 4.4.4 with a toolkit ,
didnt work . Still getting the same EMERGENCY CALLS ONLY | MY CARRIER (012 MOBILE)
and when i tried to select my carrier manually , like the thread opener did ,
I got the cannot connect to this network . try again later massage .
I honestly tried everything I know .
Im starting to think its a problem with the device and not the operating system .
since i flashed a brand new stock image and it didn't work !

At dialer press "*#*#4636#*#*" then phone information and press top right three dots. There is an option for area band. Choose your area. I'm not sure if this will solve your problem but try it

Flash twrp recovery and flash either the stock rom or custom. Just google for the links. If your bootloader isn't unlocked you will have to wait 14 days. Hope it helps
i have sent the phone back to lenovo service center .. i just got the phone 8 days ago
Im having this issue after flashing the stock rom, besides the phone goes off and doesn't wake up after 5 seconds standby, but i really want to focus on signal problem before fixing anything else.
imei numbers are fine (this phone has Dual Sim) i checked them after flashing but the issue is still there. the phone recognizes sim at both slots, but no signal.
I tryed to search networks and always says error while searching, so i think modem file which came with the rom isn't compatible with my carrier bands. in fact, it cant even get other bands from other carriers from my country.
i thought i might could use some files from other roms of same brand and proccessor which could recognize the bands from here, but didnt work, when i flashed them the phone didnt even recognize the sim ( and it could do it before) so i flashed previous files.
i've been looking for the really stock rom of my phone (Which is a090L, but i flashed a090) throught most of google, but i could not find anything.
if you guys know any way that at least the phone can see my bands i would be really grateful
if you need any file from the phone just request it i will upload it as fast as i can
Hi everyone.
Recently I have had some issues where sim cards are not working on my phone. At first I thought it was an issue with the sim cards but when I tried the sim in a different phone, it worked fine. I tried numerous restarts, taking the sim out and placing it back in (in case there was an issue with the contacts/sim tray) but this has not solved the issue. By chance I was looking at the phone identity menu and noticed that the IMEI and the IMEI SV fields both say unknown but the device serial number is fine.
I restarted the phone into download mode and checked the System info menu and IMEI number is displayed there but for some reason it is missing in the actual android OS hence I cant connect to the mobile network to make calls etc.
This all started recent after I had come back from abroad (had been using a foreign sim) and tried to use my UK sim. Up until that point, the phone worked fine with the UK and foreign sim. After inserting my UK sim, there was no signal. I got home and tried the sim in my other phone and it worked fine.
I have not modified the phone in anyway (other than flashing an official RUU to fix a boot loop issue - see here ) and it is boot locked and not rooted. After fixing the bootloop issue, I have applied all available OTAs that my phone detected automatically which upgraded the android version to 7.0 (OS 4.28.401.3).
I have tried factory resetting using the menu (not recovery mode) and this has not solved the issue. Any ideas as to how I can fix this IMEI issue?
Many thanks
Rob
Have you checked the apn settings are correct?. Have you checked other UK sim cards in your device that are known to be working?. Do you use a simcard adapter?.

Yep.. tried other simcards thats work in other phones but they wernt working on my phone.. most likely due to the missing IMEI. I also noticed that the colour of the icons on the pulldown tray were red instead of blue and the phone was sluggish when toggling wifi on and off or entering/leaving Airplane mode.
I managed to fix the issue in the end by downloading an RRU and flashing it from SD card. Everything works ok now.
Thanks for your contribution :good:
