If you don’t have another SIM card from a different network provider, you can also check by going into your phone’s settings.
Yep, simply contact your previous network provider or text ‘PAC’ to 65075 to get a code which will allow you to bring your current number over to your new SIM. This won’t disrupt your service either. Find out more about how to keep you current mobile number.
