Sim not working?


Our Customer Services team will be in touch to confirm that your bill limit has been reached, and advise on next steps to get your tariff reactivated and working as normal.

Please contact [email protected] to request a replacement sim.

Once your sim has been shipped, a link will be provided for Royal Mail so you can track delivery.

If there is an issue with your delivery, please contact [email protected]

If your delivery has been lost, we will send a replacement sim via next day delivery.

If your delivery has been delayed, we will ensure that this is reflected in the go live date.

Restart your phone.

Go to Settings > Mobile Data > Mobile Data Options > Voice & Data > VoLTE

You can then check that 4G calling is enabled.
