I had horrible issue with my StraightTalk sim card.
Had to transfer my number, which worked.
Texting and data both didn't work. And the customer support was not helpful.
Then I went to ST facebook page and their Florida office phone. Facebook was useless.
All of them kept saying that simcard/phone is fully provisioned and all 3 components of calls/data/sms should work. They also said that "service is not guaranteed".
Florida Tracfone office called in some techsupport and they submitted Level 2 (L2) ticket. Their backoffice DB had only call record, but not data or text. WTF. They finally fixed it in next 5 days.
The whole nightmare took two weeks.
I have data working, MMS working, SMS working.
Beware of not going over 2GB limit. ST can cancel your contract and you will lose your phone number.
But for unlimited calls and text and some data - 45 is a good price. Beware!
