Yes, you can! If your new phone is unlocked and compatible with US Mobile just move the SIM card from your old device to the new one.
If the SIM card size is different you can easily adjust them up and down using the size adapters that were included with the original SIM. If you haven't kept that, no worries. Just reach out to us and we'll send you another one.
The video below is an example of how you would insert it into a Xiaomi Mi Mix but the principle is the same, no matter what phone or other connected device you have. If you run into any problems call in or chat with us and we'll help you out.
