If your SIM has been lost or stolen, then don’t worry, we’ve got your back. We know that stuff happens from time to time, so let’s get you back up and running asap.

All you’ve got to do is click on the link below, fill in the short form and we’ll send out a replacement SIM to you:


We’ll then block your lost SIM straight away.

When your SIM has been blocked, this essentially freezes your service with us temporarily for your security.

You won’t be able to use SMARTY until you’ve received and activated your new replacement SIM, so this form should only be used if you no longer have access to an active SMARTY SIM. 

Please don’t use this option if you’re still waiting for your first SMARTY SIM card, or if you’ve changed your device and just need a different type of SIM.

Got your replacement SIM?

Next you need to activate your new SIM.

Activating your card is really simple. Just pop your SIM into a device, log into your SMARTY account and follow the on-screen instructions.

SIM cards should be activated immediately, but it could take a while longer, so please leave your new SIM in a powered device for 2 hours during activation. 

You might also have to restart your device before activation is completed. Don’t worry though, we’ll send you a text when you’re all good to go. 

Got an issue you need help with?

Web chat is available 8am-8pm, 7 days a week (excluding Bank Holidays). 

If you need help outside of these times, you can still submit your question via web chat and leave your email address or mobile number. We’ll reply as soon as possible.
