Check coverage at your address
Because Combo Wireless service runs on the T-Mobile network, T-Mobile's public coverage map is the best way to see expected coverage at an address.

Coverage maps are estimates. Actual signal depends on buildings, terrain, weather, network traffic and your device. Check the places you spend the most time: home, work, school and your commute.
Where we serve
Combo Wireless is an approved Lifeline provider in four states:
5G, 4G LTE and your device
Your device determines which network technologies you can use:

Tips for a better signal
- Restart your phone if the signal seems stuck.
- Toggle Airplane Mode on and off to reconnect to the network.
- Keep your device's software up to date.
- Indoors, move near a window or to a higher floor.
- Use Wi-Fi at home for heavy data use like video.

Coverage FAQs

Can I use my phone when I travel outside my state?
