Which One’s Best for You?

If you’re mainly using your phone for WhatsApp, calls, and a bit of browsing, the 10GB or 20GB deals will do the trick.
If you stream, scroll, and game a lot, step up to 35GB or 70GB.
And if you don’t ever want to think about limits again — just go Unlimited for £17 and relax.

Every plan gives you the same perks: no contracts, no credit checks, and easy cancellation whenever you want.

The Bottom Line

Smarty’s all about doing mobile differently — fair prices, clear terms, and total control.
At Olimit, we’ve made it easy to compare all the best Smarty SIM only deals in one place so you can pick what works for you and get connected fast.
