I am using Samsung Galaxy Chat B5330 (officially upgraded from 4.0.4 to 4.1.2). It used to work fine, but since a few days I am not able to call or send sms or use any network related services. It gives me error : "Not Registered On Network". I tried applying manual network settings. At first it gives a pop up : "Registered on Network". But as soon as I try to make a call, the same error : "Not Registered On Network".
Also I haven't yet rooted my phone.
I thought that factory reset would have been the solution to my problem, but unexpectedly , this too did not work for me. Please help.
Check if your IMEI is intact (by dialling *#06#)
If it's good, make sure it isn't a network problem or server error from your carrier itself

i have tried checking the imei and serial number. They are fine.
Also no problem with network provider because other phones with my simcard are able to use the network.
No problem with my sim card because it works on other phones.
Also my phone is able to use simcard of other phones.

Hi, I recently pruchased a Samsung Galasxy S6 Edge and bought a unlock code from eBay. When trying to enter USSD codes I get the same error everytime 'Connection Problem or Invalid MMI Code'.
I have looked online and tried the common fixes but no joy. Even trying to run a basic *#06# gives the same error. I have tried using a combination of + and , etc before the first digit and after the whole string but still get the same error.
Any ideas? It's driving me mad.
Cheers

With some carriers external codes wont work, so which network is the phone locked to? Contact whoever it is and get it unlocked that way.
Good luck
Hi Duncan, many thanks for your reply. I didn't realise that, I will contact Vodafone in that case. Many thanks.

No worries dude and dont feel you got ripped off, its just some external codes dont work.
Im 99% sure when you buy from the network its locked to (in your case Vodafone) you'll be unlocked and happy days

Hey there!
From one day to another my phone stopped working. I did NOT modified in any way, always used offical firmwires.
It says only emergency calls, and when i call someone it says "not registered on network".
I did soft reset/hard reset and also firmwire update, no success. Tried every single soultion in settings (setting only GSM ect ect).
It can
-see the sim card (others too, also sims are working fine in other phones)
-has signal all the time
-see every other phone network (when i try to choose any it says the same "not registered on network" message)
-IMEI and SN number exist not empty or null
I bought it from a supermarket years ago out of the box, factory SIM free, not reported stolen, have my IMEI number when i type *#06#, BUT when i enter the service mode (*#0011#) it says:
CS: reg_denied
MM state: nocellavailabe
PS: reg_denied
GMM state: GMM_noservice
IMEI CERT: FAIL
Support net block : 1
What can be the problem and how could i fix without taking it to a service shop? Any idea/post appreciated.

CS: reg_denied
MM state: Attempting ToUpdate
PS: reg_denied
GMM state: LimitedService
IMEI CERT: PASS
Support net block : 1

Sent it to Samsung service and they repleaced the motherboard and a few other stuff, but the main problem was that. I have no other info about this issue, working since then.
What about the IMEI?

IMEI number, other serial numbers pretty much stayed the same, never lost them. The only thing changed is the date of manufactoring since it has a new motherboard. It was free tho, I managed to get extended warranty, motherboard + service charge overall can go up to 100-150€ /don't take it as a fact/.
Service mode looks this now:
CS: reg_roam (roaming at the moment since on holiday)
MM state: NormalSrv
PS: reg_roam
GMM state: Registered
IMEI CERT: PASS
Support net block : 1
I want to change csc code by dialling *#272*IMEI# but I get a message saying "connection problem or invalid MMI code" everytime.
I have a dual sim Samsung Galaxy A50 SM-A505FN.
Does anyone have a solution to this?
