Love your phone but want smarter wireless? That’s BYOP. Bring your own compatible phone — like most unlocked GSM ones, or those from AT&T or T-Mobile — and hook it up with Straight Talk's awesome service.

The quickest way to know if your phone is a match is to use our online compatibility checker. Just enter your phone's details, and we'll tell you right away.

Once you've confirmed compatibility:

2. You can activate at Walmart Stores or head to our website to follow the simple steps.
