Hello,
I have a weird problem after I replaced my USB port chip. I'm in India and my carrier is Airtel. When I turn the phone on, I get Emergency calls only and when I try to call anyone, I get Not registered on network. The weird thing is that SIMs from other carriers are working fine in the S2 and the Airtel SIM itself is also working fine in my other phone. When I look for networks, the phone shows all available ones but not the Airtel network.
I've tried flashing a couple of ROMs, including the latest one in the Stock official thread (unbranded of course) here on XDA to no avail. Have not wiped anything yet though. Help please!
EDIT: I have checked the keystr file and my IMEI is fine too.
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.
Hi all, I recently got a weird and strange issue out of the blue 2 days ago. No update/changes made just before issue, no playstore update done too for at least 4 days before issue popped up.
Sim Slot 1: Airtel 4G
Sim Slot 2: Idea GSM
Android Version: 6.0 (Moto's OTA official release)
Baseband Version: M8916_2020629.41.03.21.51R SURNIA_EMEA_DSDS_CUST
Kernel Version: 3.10.49-g4979ca4 [email protected] #1
System Version: 24.51.39_SURNIA_retasia_ds.retasia all.en.03 retin
Build Number: MPI24.65-39
Unrooted and Locked bootloader
Issue: 1 SIM doesn't connect to network
1. Airtel was receiving 4G signals without any problem for weeks, however 3 weeks ago, it showed only "H" which is fine with me and working decently well.
2. Was watching a YouTube video, the Airtel network on SIM Slot 1 goes off. Searched for network, gets message "Error while searching for network", Idea on SIM Slot 2 works fine.
3. Airtel SIM is fine, both SIM Slots on Moto E2 are fine. Tested different combinations with my other SIMs and handsets.
4. Did airplane mode few times, no go, did radio turn off and on in *#*#4636#*#* . Gets lag there. Turns off on touchwiz but inside 4636 still shows on button to turn " off" radio, also selected LTE/GSM(PRL) in preferred network ther.
Played a little and found 2 temporary workarounds.
Workaround 1 : (Fixes problem for 5 minutes or so)
Disable SIM in Slot 1, Switch mobile data to Slot 2, enable SIM in Slot 1, gets network, switch mobile data to Slot 1, gets "H"... Slot 1 at "4G recommended" by default, 5 minutes later, network goes off. Search for network, mostly get "Error searching for network", randomly, Slot 1 detects Airtel network, when connected, says " SIM doesn't allow connection to this network", back to square one...
Workaround 2: (Has been fine for past half hour while I am typing the issue here using the problematic connection)
Set Slot 1 to 3G as soon as it gets working network with working 3G, after doing exact same steps as in Workaround 1.
To be noted: 4G/3G Airtel Network is fine in area, Airtel SIM is fine, SIM Slots are fine, other Idea SIM in Slot 2 doesn't show any problem at all and connects to internet too just fine on EDGE ( as it's a 3 yr old sim) , numerous restarts done, app cache cleared.
I am a Noobie, so please bear with me, I posted all the relevant details I could think of, as detailed as possible. Phone is 2 months old only, came with lollipop, upgraded to marshmallow through Moto's OTA update, never rooted or played around with ever.
This is driving me crazy, I could logically only think of some problem in the OS causing this issue without any warning or apparent reason... Tried different forums, no one posted about facing similar issue in India anywhere yet.

I haven't seen this issue on my phone either. I have the Indian 4G Variant as well (XT1521). I would Recommend u to go to recovery mode and wipe data and cache (This should completely erase ur phone and hopefully fix ur issue). If this doesn't work I'd recommend u try and unlock ur bootloader and flash CM13 and test if this issue persists. If this issue persists I believe it's a hardware problem. Don't worry unlocking ur bootloader will void warranty but relocking it is extremely easy which will prevent ur warranty from being void.
Best of luck[emoji2] [emoji2]

Thank you for suggestions
Hi All,
Just to update, my workaround 2 has been working so far without any problem for the past 1 week, I can put airplane mode on and off and it comes back, I restart too and get proper network on both sims and the 3G mobile network of Airtel. Scared of putting recommended network as 4G for Airtel or playing around with it more for now fearing I may lose it again. If I have to do in future, I'll post the outcome..... :laugh:
I've wiped the cache though from recovery mode as suggested... don't know if it changed anything... Also did all playstore updates without problem.

I couldn't see any posts about this for over 20 pages, I apologize if this is a known solution.
I just fixed, and bypassed FRP on an Honor 5X at work and I started using it all day with my AT&T SIM card. When I got home, it says "network unavailable" where the carrier name should be on the top left and it leaves me with absolutely no connection to the network. It does, oddly enough, register the phone number so the SIM card is being read. I tried the APN settings and nothing.
I have not rooted it yet, there's no TWRP files, just a stock phone. And yes, the SIM card does work in the Galaxy S5 Active it's in right now. Any idea how to fix this?
It isnt working in those two phones if am not wrong !!
Hi,
I purchased a USED Galaxy A7 2018 dual sim F variant. When I first inserted my SIM card, it was working fine. 4G and calls, all were working.
But after I factory resat it, mobile network stopped working or even detecting. SIM card is still detected and I can see it in "connections" under SIM cards in settings app on my phone. But when I try to dial a number it says "not registered on network". On lock screen, it says emergency calls only. When I go to "mobile networks" in settings app and tap to select network automatically or manually, it gives error that unable to find/connect to a network.
I tried three different sim cards yet same thing happens. SIM cards work just fine in other phones. Also, it is not a problem with sim tray on phone as sim card is detected and shown and as I said before, mobile network was working fine before resetting the phone.
When I purchased it, there was a custom ROM installed on it and OEM Unlocking was ON. I installed latest stock ROM from Samsung plus a couple of stock ROMS but same thing happens with every ROM.
I am out of ideas on what should I do now. I would really appreciate any help anyone can give.
Thanks.
Finally found a solution.
