These optional services are paid for by crediting your Wallet in your Mozillion Dashboard.

How can I check my Wallet balance?

What happens when I run low on credit or run out?

We notify you when you reach a balance of 20% remaining, you can select Auto Top-up in your Dashboard so you never run out of credit.

Simply top-up to re-activate these services.

Do I get a new SIM when I top-up?
No you do not, the Wallet is a function linked to your existing SIM card or eSIM to enable out-of-bundle chargeable services?
What are the prices for Out of Bundle services?
View our Price Guide for all out-of-bundle charges.
Can I credit my Wallet whilst abroad?
Yes, simply login to your Dashboard and top-up.
Does Wallet credit expire?
No, the credit added to your Wallet has no expiry date, unless specifically stated on a promotional plan.
What happens to the credit in my Wallet, if I change networks?
We will repay your credit balance by BACS less an administration fee of £5, or the balance of your account if it is below £5.
Why isn’t my top-up credit working?

If credit hasn’t been added to your Wallet, there could be a few reasons for this. Your payment may not have been successfully completed, in which case the credit will not be added. Sometimes, payments can also take a short time to process before the credit appears in your Wallet balance.

If you have Auto Top-up enabled, the issue could also be with how it has been configured, which may prevent the credit from being added automatically. If your Wallet balance reached zero, out of bundle services will also be suspended until you top up again, so the credit may not activate immediately.

Check your payment status and Wallet balance in your Mozillion Dashboard. If the credit still hasn’t appeared after some time, please contact Mozillion Customer Service.
