Straight Talk Wireless Forums

Hello, I recently purchased a new straight talk byop plan. I have a metro pcs samsung galaxy avant that I network unlocked with the carrier code. I used the term Mobile sim card, because I thought I had to since metro pcs phones run off to mobile networks.I'm moving, and will have no coverage, unless I switch to AT&T.
I lost the AT&T sim that came with the byop package. So my question is, can I use a different AT&T sim card, or how else can I switch carriers from t mobile to AT&T?
