If you are on a Cricket unlimited plan, you can have high-speed data in Mexico and Canada. The data speeds in Mexico and Canada are subject to the capabilities of the local service providers, your plan, your location, and the type of device you are using. If you are not on an unlimited plan, once you go above the high-speed data allowance included in your plan, the speeds are reduced to a max of 128Kbps for the rest of your monthly plan cycle.
