Unfortunately, I don't know what the carrier includes with the devices, unfortunately. There is a box contents list, but unfortunately, those manuals aren't available online. While I'm unable to answer the question, A T-Mobile representative would likely be able to assist to see if the cable is included, or if one is available.
Some authorized carrier service centers also have the ability to transfer contacts, pictures and other media from one device to another as well.
I have the T139 phone for T-mobile. I want to upgrade to T349 or T429; however -- The T139 phone does not have a cable to transfer the pictures from phone to computer.
Would anyone know if the T349 or T429 have cables that can transfer pics to the computer? I had a NK 2720 and it had a camera, but couldn't find a cable to fit the model.
I would take the sim out of the T139 and transfer it to the T349 or T429. Thanks for your comment.
