Coverage

There are minor differences in coverage depending on which network you choose to use. Our Warp 5G network has slightly better coverage in some rural areas. However, GSM LTE and Warp 5G are almost equal in larger, more densely populated areas.

You can use our coverage built into the ‘Networks’ page to check which network has better coverage in your area. In case of any questions, you can also reach out to us via chat, email, or call!

Device compatibility

Due to recent changes to our GSM LTE network, for devices to be now compatible, they must come with "4G" or "LTE" capability and also have VoLTE/HD Voice/Enhanced Calling. The requirements for our Super LTE network are a bit different, so we also have a handy compatibility checker built into the ‘Networks’ page. If you need help figuring out whether you can bring over a device or not, please reach out to us, and we can help confirm that for you. Most Apple, Samsung, or other newer devices are compatible with both of our networks.

If your phone isn’t compatible or you need a new one, we have a selection of inexpensive and unlocked devices in our store, which are compatible with both of our networks!

If you want to know whether our service will work on your IoT devices like alarm systems, GPS trackers, smart-watches, or other related equipment, please reach out to us via chat, call or email with any questions you may have, and we'll try our best to answer them for you.

We're around 24/7 and love helping people tailor our services to their needs.
