i have a straight talk account. up until yesterday i had at&t based straight talk sim on my 3gs. everything worked great. Yesterday I switched to Tmobile based sim card and I am using a tmobile phone. I can make and receive calls, access 3g data, and send texts to anybody, but i am unable to receive texts. I can only receive texts from another tmobile number or my own phone.
There is also a thread at howardforums where people are having the same issue.
Please help
