We started Honest because we were fed up with the big networks. There had to be a better way.
Back then, every new customer felt like a huge win. Now tens of thousands back our mission to set a bold new standard for mobile.
And we're just getting started. We won't rest until rubbish signal and expensive roaming are ancient history.

We started Honest because we were fed up with the big networks taking advantage.
Annual price hikes, complicated contracts, not enough sustainability action... the list goes on.
After launching our essential everyday Classic SIM, we knew people still faced two big problems: rubbish signal and expensive roaming.
So we built Smart SIM, our game-changing backup eSIM giving you unbeatable signal and free global roaming.
More than 100,000 happy customers have already joined us. We'd love to welcome you onboard too.
Unlike the big networks, we believe it's time for change.
It's time for mobile done right.
