Imagine if every time you lost signal you could just hop onto another mobile network

(We’re Andy and Josh by the way, Honest’s founders 👋)
We built Smart SIM to make that a reality
It works alongside your main SIM to provide unlimited data on 200+ apps across three major UK networks, plus free roaming in 180+ countries.

So when your signal drops or you go abroad, you automatically connect to another network. Keeping apps like WhatsApp, Google Maps, Uber and Monzo at your fingertips, with unlimited data to boot.

Fed up with bad signal, dodgy wifi and expensive roaming? It’s time to get a Smart SIM.
