I was told by a BB ATT rep that BB's with OS V4.3 and later have the option to send and receive all MMS formats(pic, vid, etc...) without having a data plan. I have the unlimited txting plan. My phone is up to date, running a version higher than v4.3, yet i still can't get the service books for MMS. I have even tried my sim in a TMO 8100 running v184.108.40.206 (Platform 220.127.116.11) and it works just fine. any help, suggestions, i just can't get this to work.....
With a T-Mobile BB on AT&T you will need an AT&T BB data plan to get the books for MMS. Use the plan for a month and then cancel if you want and the books remain.
