Good question. We’ve always done things differently at Honest on our mission to build the best mobile network on the planet.
After introducing Classic SIM to thousands of happy customers, we still felt signal and roaming could be better. So we developed Smart SIM.

We love your enthusiasm, but it’s a no. You'll need your main SIM for calls and texts, social media and streaming, and web browsing.

No, although this might change if enough people want it to. We created Smart SIM as a second SIM – as most phones only have one slot for a physical SIM, it’s eSIM only for now.

Just make sure your phone is eSIM compatible before ordering.

No, and you don’t need to. Smart SIM is a VPN by default and fully secure. Think of it as a digital fortress for your data 🔒
Afraid not. To keep Smart SIM affordable, we’ve limited it to apps that don’t gobble up endless data. That means social media and streaming are off the cards (for now, at least).
On the flip side, you have more than 500 apps (and counting) at your fingertips, whether you’re on the train, on your travels or out on the town. Plus, it’ll give you a break from all that doomscrolling 😉
