⚠️ Before you start

Only proceed with these steps if you bought your SMARTY SIM through our website smarty.co.uk.

If you received a bonus SMARTY SIM, or bought one in a shop or other retailer, go to smarty.co.uk/activate and tap “Let’s get started” to sign up and activate your SIM instead.

Activate your SIM

Got your SIM? Log in to your account and tap “Activate SIM” to begin your billing month and start using your data, calls & texts.

Activation should happen in just a few minutes, but could take up to 2 hours.

We’ll send you an email and a text to your SMARTY SIM when your SIM is activated.

You’ll automatically get a brand new SMARTY number when you join. You can start using this number as soon as you activate.

You can also activate your SIM and manage your account using our new SMARTY App!


Having issues activating your SIM?

Restart your device, if you haven’t already, to check that everything is up and running properly with your device.

Make sure that your phone is unlocked.

If it’s been more than 2 hours and you’re still having issues, contact a member of our support team via webchat who can help get this sorted for you.

Want to keep your old number and bring it over to SMARTY?

Follow these easy steps to transfer your previous number. We’ll also close your account with your previous provider for you as part of that process.

Want to cancel your old number with your previous provider?

If you’d like to take away the hassle of talking to your previous network provider, we can terminate your previous phone number and your services with your previous provider for you. Simply follow these steps to cancel your previous number. Only continue with this if you’re ok with letting go of your old number as you won’t be able to get it back.

Don’t have a SMARTY SIM yet?

Check out our plans on smarty.co.uk and order a SIM online or purchase one from a participating retailer.
