I have the phone for about a 3 months now. When I first got the phone i was the free $10. I could surf the web, send texts and call. I purchased the $35 card after the free minutes expired. Everything was fine. Then I bought a $15 minute card. After that I cant send text messages at all or post to post to facebook. i have bought the $35 card after that and the phone still wont send messages.
