Finance & Data Manager

Hello, we’re Honest. 👋 The clue’s in the name: we’re the network doing mobile right. We’re on a mission to set a bold new standard for mobile (and drag a broken industry into the future while we're at it). It started with Classic SIM, our essential everyday SIM that includes bills that drop, support in seconds, and a shrinking carbon footprint. Thousands of happy customers joined us. But we knew people still faced two big problems: rubbish signal and expensive roaming. So we built Smart SIM, our game-changing back-up eSIM giving you unbeatable signal and free global roaming. Whenever you lose signal or go abroad, you can switch to Smart SIM in just a few taps for 500+ essential apps on EE, O2, Three and Vodafone, plus hundreds of networks worldwide. Now we're proud to have more than 63,000 customers on our journey. We’re also the UK’s first B Corp mobile network, a carbon-negative company and member of 1% for the Planet 🌎
