ALL CARRIERS are compatible with RoboKiller in the US and Canada. Let us explain:
Currently, in the US, Verizon, AT&T, Sprint, T-Mobile, Cricket, MetroPCS, business class C-Spire are compatible with the full-featured version of RoboKiller.
In Canada, Roger, Bell Mobility, TELUS, Freedom Mobile, and MTS Communications Inc. are compatible with the full-featured version of RoboKiller.
In Mexico, RoboKiller is available on Android only. Telcel, Movistar, AT&T Mexico, Virgin Mobile, QBO Cel, Weex, Cierto, Maz Tiempo, Oui Móvil, Flash Mobile, and Unefone are supported by the Basic version of RoboKiller.
If you do not see your carrier listed above, your phone carrier may not offer a feature called "Conditional Call Forwarding". Don't worry! You will still be able to use a basic version of the RoboKiller app which does not utilize the features that depend on conditional call forwarding. This means ALL CARRIERS are supported by RoboKiller.
