I bought an unlocked t mobile sidekick lx 2009 and was planning on using it with my rogers pay as you go sim card. I can make calls, and it will connect to the rogers network fine, with 3 to full bars all the time. I cannot send text messages though...whenever i try, i get the message: "youre message could not be sent and cannot be retried." There has been two messages that have sent, though but then it will not send them again! On my pay as you go plan, i have unlimited web browsing, calling, and text messaging. This is really bothering me! Any help is appreciated!!!
