Is Simp really unlimited?

UK data, calls and texts on your UK eSIM are unlimited on Simp+ and Simp Pro, and we never slow you down.

Yes, properly unlimited. UK data, calls and texts on your UK eSIM aren't capped, and they're not unlimited-for-some-apps-only either.

Will you slow me down? Never. We don't reduce your speed at any point.

Fair use. Unlimited is for normal personal use, not for replacing home broadband or running a business. The details are in our terms and conditions.

Abroad it's different. Roaming has its own allowances: see How much can I use abroad?
