I took my sim card out of my at&t pantech pursuit and cut it into a mini sim with one of those tools that you can buy online. I have been using for these last few months and it's great, but yesterday I was in the car with my brother and all the bars disappeared and it said no service, so I restarted it because it does that sometimes, but now it refuses to connect, it doesn't even recognize my number anymore, I put it back in my pursuit and it works fine in there, but whenever I try to switch it back that iPhone won't connect. Any ideas? Do I need to restore it?
