The UK's cheapest unlimited SIM. From £10/month

Unlike the cheap “unlimited” deals that turn out to be unlimited-social-media-only with a capped general allowance, Simp is unlimited for everything you actually do on your phone.

Both plans are eSIM only and set up in minutes in the app. Students can claim a discount via Student Beans. 100% 5-star reviews on Trustpilot.

• Cheapest unlimited in the UK. £10/month (Standard, paid quarterly) for unlimited data, calls and texts - unlimited, not a capped or social-only tier.
• Worldwide roaming included. EU roaming plus unlimited 4G data roaming across more than 130 countries, at no daily charge - while most UK networks charge £2 to £8 a day to roam, or reserve worldwide roaming for premium plans. See how roaming works.
• No contract, no price rises. Rolling monthly, cancel any time, and the price you join on is the price you keep.
• eSIM, set up in minutes. No physical SIM; works on eSIM-compatible iPhone and most Android phones. Keep your existing number.
• Rewards built in. Daily Spins tickets and coins towards rewards, plus a referral bonus.

Unlimited UK data, calls and texts on both plans - genuinely unlimited, with a fair-use limit of 750GB a month for normal personal use (it's not a home-broadband replacement). Global roaming runs at 5G speed up to your plan's allowance, then continues unlimited at 4G speeds in the supported countries listed in our terms (up to 10GB of usage).

What is an eSIM and will my phone work with Simp?

An eSIM is a digital SIM built into your phone, so there is no physical card. Simp is eSIM only and works with eSIM-compatible iPhones and most Android phones; check your device is eSIM compatible and unlocked first. You set it up in minutes through the Simp app.
