andyb: ....you have mobile data enabled ?

petinar:

andyb: I suspect it's been rooted, and the rom installed is the issue. If you know someone who knows how, you could install another one, but it's a case of "at your own risk"
Weird that it did work though.

Yes very weird and most annoying now! Any clues as to how I find the telecom one like the telecom guy said?

Are you absolutely sure the APN settings are the same?  Have you tried restarting your phone?

I really, really wouldn't recommend rushing into installing a new ROM especially for a new user.  It's fairly straightforward, but you do run the risk of 'bricking' your phone if you tick the wrong check box.

When you go to Settings - About phone, what does it say?

KevinL: Can you screen shot your APN settings too?

KevinL: Your APN settings look OK.

Have you tried turning off wi-fi?

KevinL: Your phone is running a generic europe firmware, and assuming you purchased it new it won't be rooted, so no need to explore that further.

Can you send MMS messages using your phone?  Have you ever sent MMS messages from your phone?  In some cases you need to send an MMS first in order for the system to recognise that you have  an MMS-capable device (although this was a few years ago).

One other thing I would try is putting the sim card in another phone (preferably the dumbest dumb-phone you have) to see if it can download the MMS (presuming the MMS is somehow corrupted).  Once the MMS is downloaded, put the SIM card back in your Galaxy S2 and try to send it another MMS.

If setting the APN settings with Tweakker, and clearing the data/cache from the messaging app don't work, then maybe I'd try a factory reset - you'll lose your applications/settings/data though (although when you sign back in to google it'll mostly be restored).

michaelmurfy: Actually for what it's worth I am having the same problem with my SIII - APN settings are correct, I am running Cyanogenmod 10 on it but didn't even want to receive MMS on the stock firmware (and even tried the Telecom NZ branded firmware) - My phone is the international model SIII

No matter what I do I can't receive MMS, can send out fine, and believe me when I say I have tried literally everything in an attempt to get them to come through.

tonyhughes: Guys, use the detailed MMS settings further back in this thread, (I.e. Make sure your APNs are spot on), then install Go SMS Pro, then send yourself an MMS (or click download on all your failed ones).
