MMS: Can i make my 2G identify itself to the network as a 3G?

[Moi un Mouton]

I have an unlocked 2G phone that I have put the ActivateMMS2G application on. I am in the UK.

I have tested it with my Tesco pay-as-you-go SIM and it works perfectly for sending and receiving. (Thank you to the application creators! )

However, my main contract is with O2, and when someone sends me an MMS on that, the network sees that the phone is a 2G and generates a text message saying I have an MMS and to go view it on a website. (I can however send MMS on O2, strangely)

So my question is this - my phone is sending an ID to the network that tells it it's a 2G iPhone. Can this be hacked, to make it identify itself as (say) a 3G or as a Nokia? Or is it the IMEI that is being used to identify it?

(By the way, the Tesco service uses the O2 network, it just doesn't block MMS in the same way!!!)

Hmmm I would also like to know this. I called O2 to activate MMS on my account, which they were fine with. All I had to do was send a blank text message to a number and it would be finished. I recieved a text back saying it couldnt be activated because I was using a 2G iPhone

There is User Agent for MMS, you can make it so it will identify as a different phone. I am not sure if it will solve your problem though.

They should be able to turn it on from the office. There should be no reason why you need to send a message. Best thing would be to call up again and ask for it.

Or change to a normal phone, send the text from that phone and then you should still have MMS enabled when you switch back to the iPhone.

I did both those things

1. They just refuse, even when I threatened to cancel my contract

2. I did that, MMS's come through to my Nokia, but not to the iPhone, using the same SIM
