F.A.Q.
Sideline uses your carrier network. Incoming calls ring like normal with a “Sideline” caller ID. For outbound calls, just open Sideline instead of your native calling app.
This gives you the same great call quality and reliability you get from your regular number.
If you have unlimited minutes on your carrier plan, Sideline calls don’t cost extra. This is the case for most cellular customers in the U.S.
If you have limitations on your carrier plan, know that Sideline uses your calling minutes. Check with your carrier to see if any calling or messaging fees may apply.
Nope. Texts are totally free.
Yes. Sideline calls show up on the monthly statement from your service provider. They’ll appear like calls from your regular mobile number.
Yes. Do what makes you happy. Subscribing to Sideline Pro lets you toggle between WiFi and carrier networks.
