If you have an iPhone, you’ll find the SIM tray on the side of your phone (below the lock button). If you have an Android device, the SIM tray may be on the top or side of the phone. You’ll know you found the SIM try when you see a long oval shape with a tiny little hole (about the size of a pin hole).
Have an older model phone? Check behind your battery of the phone for your SIM slot.
If your device can hold two SIM cards, place your new WOW! mobile SIM card into the first tray (it will be labeled as the first tray) to ensure you receive proper coverage.
