Does TickTalk work with Verizon or Sprint?

At this time, TickTalk is not compatible with Verizon or Sprint, but it is compatible with GSM carriers like T-Mobile and TickTalk Wireless. We recommend using the included TickTalk Wireless SIM on either AT&T's network or T-Mobile's network for an affordable, pay-as-you-go, no contract option for U.S. customers.
