Sign up with sprint picture mail service. 1ST !
Download the latest app for picture mail from the sprint site that is the default url for Pocket IE and install it.
Sprint does not offer true MMS for the TP.
They essentially let us use an app to upload the pic from our phones to their site, then they in turn take that pic into a queue. They have 1 or 2 modems that grab the pics and phone numbers and send em out through a dedicated modem. They also send it down as a regular email, but the picture app takes the message apart and uses the info in it.
When you go to try to send your first pic after already signing up for picture mail service, you will see a dialog that says "Configuring Your Device", it will run through the process and then you will be prompted with another window to add your recipients. Use an address from the contacts to see how the number should be entered.
Dont send full 3MP "MP=Megapixel" pics. Most carriers set a limit on the receiving side. I know for a fact that verizon does.
My wife cant receive anything above 2MP's on her phone.
Start with a small pic and then work your way up.
Once you get a pic through, test recieving one. you should get a noification icon up in your top notification bar letting you know you got a new picture.
Hope that helps..I know sprint isnt that much help. So I feel for ya.
They really need to open up the old method they had available for Pics back in the days of ArcSoft MMS. That was good pic sending..!
