[Q] Unable to Register on any network Please help.

I just sold my i9003 to my friend. When he inserts his airtel sim or any other sim and give a network search and click on airtel (or corresponding network) he gets the error message 'Can't connect to this network right now. Try again later' several times in two days we have tried and still get the same error.
Ref: My original sim in the phone :Airtel
My rom : cm 10.1 alpha 9 (Dhiru)
I have tried reinstaling the Rom to no avail. Please note that this problem is only recent. I have been using this rom (cm10.1 a9) ever since its release with no issues, the issue occured only when I changed to a different sim. However, it still works on my sim.

SIM not working

Greetings!
I bought Magnus last November and everything seemed to work fine until now.
The phone is now not recognizing both SIMs simultaneously.
First I thought it might be a hardware problem with the SIM slots but have made sure that both the slots are working fine and so are the SIM cards.
I found out that the SIM 2 gets activated only when I turn SIM 1 off in the SIM Management settings, otherwise there is no network recognition.
I’ve also tried removing recently update apps etc but alas!
Any ideas or anyone went through the same before?
Thanks in advance!

Thanks
I am giving some shots at home before I go to the service center, its horrifying!
Last night I did a factory reset on the phone but alas the problem still persists.
Before flashing it, can I try Hard Resetting it? Will it make any difference?
Thanks in advance!

Working link for the Stock ROM?
I hope it will not be different from the one that is pre-installed.
Another strange behavior which I noticed today:
(Original SIM Cards: SIM1 : Vodafone, SIM 2 :Reliance)
I swapped the SIMs just for the sake.
But this time instead of SIM 2, SIM 1 is showing the same problem which is Reliance in this case.
Can there be a problem with the Reliance SIM Card?
Will be testing it by replacing a 3rd SIM soon.

Bro Bro listen......
I think there is problem with your Reliance Sim card..Phone is working fine...IF there were any fault in the Phone in the SIM 1 then it wouldn't have detected the Vodafone Sim...
BTW try With a new Sim..Until then no need to flash the stock Rom...
If the problem persists then just comment here..will try my best to guide you

I tried another SIM as SIM 2 & Vodafone as SIM 1. It worked fine & the original Reliance SIM is working fine on another phone as well.
I called up the Reliance Service Centre, told them about the probelm & they said that this is some network issue & my complaint will be resolved within 3 days!
Now the problem is beyond my understanding, as I swapped the Sim cards again, Vodafone as SIM 2 & the other one as SIM 1
& to my surprise it is not working and showing the same behavior although it was working fine before!
The original Reliance SIM is still working fine on a separate phone!
Now what bothers me the most is, Is that even possible to be a network error?
But I can now give a try to flashing the stock ROM, but I need to be assured that it'll be the original ROM and will not void my warranty.
If so, then please provide me a working downloading link for the same as I have already downloaded SP Tools!
I just came across this post in the forums:
" Try downloading mmx canvas stock recovery from below link and follow steps.
http://forum.xda-developers.com/atta...1&d=1370782052
Put file recovery.img in your root of sdcard
Use MTKDroid tools to flash it instead of MobileUncle Tools"
Will this help or the original ROM?
Thanks in advance.

Abhinav

SOLVED
Sorry for being a little late.
The problem was with the Reliance network!
When I called them up they said they will look into it.
And weeks later they called back and said that this is a very common problem which has now been solved and they refer to it as
" Cross Connection Error "
I don't know what the hell is wrong with them!
Anyways, thanks a lot for replying.

Either your SIM has a problem or the ROM has a problem.
1) Check if SIM works in other phone.
2) Flash a different ROM and check again for network.
3) Check if another SIM works in the Nexus S.
4) If none of the above work then may be your SIM slot has a problem.

XT1033 - Sim card 1 problem (don´t make calls, only internet)

A few days ago the sim card 1 began to get strange behavior and I have not changed anything on the device and even crashed or something. The device detects the sim card inserted, connects to the network and to the Internet but does not make calls (MSG: Call ended)!
Inverted the sims and the problem persists. When I put the sim card in slot 2 it works normally.
I called the operator and has no problem in the network of the region.
It will be a problem on the device?
Attempts made: hard reset, reinstall the rom, rom exchange ..
Phone: XT 1033 - Rom Android6.0.1_NX_R10.1

dude, have u tried 5.1.1 based rom? I have xt1033. this problem I've faced on every MM based rom (yah I've tried all rom). I've wrote on several post, no one answered me.
problem is weak network signal, call drop, signal lost frquently, non stable connection.
only working MM rom on dual sim model xt1033 I found just "Aosp/caf by flashhhh".

My RN7 Pro is stuck on EDGE network. PLEASE HELP. Tried most of the settings.

Hello people, i need some help with my Redmi note 7 pro..
(I'm from INDIA)
Here's the Problem:
I'm not able to use 4G network on my RN7P. I'm stuck on EDGE network. My Sim card is 4G and I've checked almost every settings available normally on my device to help myself.
This problem came after a soft reset (i did that from the settings, not the recovery) .
And here's the twisted part, sometimes I get the 4G network without doing anything, but that happens like once every 2-3 months. And as soon as i restart my device or shut it down, I'm again stuck with EDGE network.
important points:
1. 4G network works fine on my Sim card on other devices (tested). I'm using Airtel.
2. I've checked most of my settings. (Including APNs)
3. I have tried to again reset my phone. Unfortunately it didn't help.
4. I haven't rooted my device, didn't unlock the bootloader and neither installed any custom rom.
5. I'm running MIUI 11.0.2.0 on top of ANDROID 10.
6. Please help me, I'M a student and its getting difficult attending my online classes because of this network problem.
7. Signal strength is always around -51 dbm 99 asu
Some questions:
1. HOW DO I FIX THIS!!????
2. WILL FLASHING A CUSTOM ROM FIX THIS ISSUE?
Okay, so I'm very new to XDA forums, i created my account only a few minutes ago. But i used to visit this site for Downloading custom roms.
Please help me out
