Check your destination before you fly.

Every country your FlexiFone SIM works in, what the data cap is, and whether calls and texts are included. Search once β€” the answer for your SIM is on one row.

Which countries work depends on which SIM you have β€” V1, V2 or V3. Find yours in the FlexiFone app or My Account under Home Screen, then pick it below.
