Hey everyone, I'm new here so sorry if this is in the wrong spot.
So yesterday I got a Blackberry Curve 9300 and as soon as I put in my sim card I set up the wifi. I don't have a data plan and don't plan on getting one. After I set up the wifi I was able to text and make calls and browse the internet, but but when I disconnect the wifi or leave my house I can't send/receive texts or make calls. Why is this? I'm on Tmobile if that means anything.
