Coverage

The network you pick can affect how good your coverage is, especially in different types of areas. Our Warp 5G network is a bit better in rural areas, but in bigger, busier areas, both GSM 5G and Warp 5G are about the same.

You can see which network works better where you live by looking at the coverage on the 'Networks' page. If you have any questions, you can talk to us using chat, email, or phone!

Device Compatibility

Because of recent changes to our GSM 5G network, devices need to have "4G" or "LTE" capability and also support VoLTE/HD Voice/Enhanced Calling to work with it. The requirements for our Warp 5G network are a bit different, so we have a tool on the 'Networks' page to check if your device is compatible. If you're unsure, feel free to ask us, and we'll assist you in finding out. The majority of recent devices from brands like Apple and Samsung are compatible with both networks.

If your phone doesn't work or you want a new one, we offer affordable unlocked devices in our store that can be used with either network.

If you're wondering whether your IoT devices like alarms, GPS trackers, or smartwatches will work with our service, you can contact us through chat, call, or email. We're here to assist and will try our best to answer your questions.
