I was trying to dial *#06# in order to check my IMEI and I keep getting the error "Connection problem or invalid MMI code." I'm currently running the at&t version on Diet ICS 7.11.12. Any idea what's up?
From my understanding, codes don't work on phones with custom software.

Hi,
Just got my S3 yesterday and having issues logging into my samsung account (which ive edited online with the S3 details) but when i enter my username and password, i get "processing failed" - just wondering if anyone else faces this issue and how can i resolve?
I unregistered which solved part of the problem, but I can't seem to access the Samsung Apps store....I am rooted, so does this make a diff?
Thanks
Hi ... only recently my S3 start appearing this message INVALID LONG:"" .... (see attachment)
Not sure what I did or apps I have installed ... but not able to find any news on this error message on the net ....
Maybe someone has encountered the similar problem .... would be grateful for any advice to seek out the problem ....
Thanks.
first off when i input the code i get nothing, nothing happens.
when i call the code this appears "Connection Problem or Invalid MMI Code"
i searched for solutions but nothing
help pls
Codes only work on touchwiz firmware, aka. Samsung stock or modded if I remember correctly.
Also, if you're using other dialer than original you can get same error.

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
