Ive only tried sending one MMS and it didnt go through, But i was using ChompSMS and i heard it doesn't support them. Not really had a look at that half of the phone yet

 

Check the APN settings:

~Settings > Wireless & networks > Mobile network > Access Point Names

Once you're here click on whatever carrier you're using and then check the settings for the server/password etc with T-mobile settings.

 

Have you tried sending yourself an MMS?

I know when my DHD arrived I couldn't send or receive MMS messages until I sent myself a photo via MMS, from my DHD to my DHD. This sorted it all out and worked within minutes for both sending and receiving.

 

I would contact T-Mobile again. I had the exact same problem with my DHD on T-Mobile and had to speak to a couple of people before they talked me through configuring the correct data service. The sending a MMS to myself method did not work for me until they gave me the correct APN settings.

 

when mine arrived it had a note from tmobile saying they are experiencing problems with mms and an a OTA update will be available in the next few weeks

 

The update that fixes MMS issues is already available for non-branded handsets so if your handset isn't branded try a software update.

 

Branded = A handset that has been altered (vandalised) by a network service provider to run on their own version of the original software.

If I turn on my HTC Desire HD I get the original software but someone who buys a DHD from Three in the coming weeks now they have their branded handsets on the way will get a three branded handset. It will look slightly different and take longer to get updates, sometimes months and on some occasions - never.

Branded phones in my view are a nightmare and should be avoided at all costs.

 

Yep, that's a common problem with branded handsets. You have to wait a while for updates that the rest of us with non-branded handsets get straight away.

 

same for me too. tried to phone t-mobile earlier but offices were closed.
had phone a few weeks now. never knew i had a problem till i recieved a pic message earlier and had to view it online, not ideal.
get the finger out t-mobile!!

 

anybody on tmobile had any joy with this?

 

I'm on TMobile and have a DHD.

Picture messages send fine to and from my handset.

I have an unbranded handset, not sim locked.

 

No. It depends where you bought your handset from.

If you bought from Carphonewarehouse for example, they sell their DHD handsets on TMobile unbranded. If you buy from TMobile directly on the website or via a TMobile shop then it's branded.

There are huge advantages to having unbranded handsets over branded ones.

 

Hi. Having problems only sometimes with mine when sending mms.
Did you have to do a backup before the factory reset?

Cheers
