We were fed up with roaming fees and dead zones

So we decided to build something better.

Smart SIM works alongside your main SIM, giving you hundreds of essential apps with free global roaming and on major US networks. Just switch in a few taps whenever you travel or lose coverage.

No more expensive day passes, clunky SIM swaps and unreliable coverage.
