is ur nuraber ported? if so... that's why lol best thing to do is to stop in a corp store and request they file a help desk ticket which will fix your problem in about 3-5 days...make sure to have examples of the nurabers youre trying to send/rcv to/from and what carriers they are with - if you get a good rep they should ask but make sure to tell them that your nuraber is ported and that they include that in on the tck ALONG WITH THE EXAMPLES OF THE NUrabERS, i filled 8 tickets on monday and forgot examples, and looked like a durab *** calling all my customers back cuz their tck was rejected cuz im a ******* haha ... @ least in milwaukee, ALL ported nurabers are having issues with sms and mms so dont feel bad lol
