Open Settings in the SimFuse app to view your account and available preferences. Controls can differ between the app and website.

Sign-in and email

Use the sign-in method linked to the account, such as Apple, Google or an emailed sign-in link. There may be no SimFuse password to change.

A receipt-email or purchase-linking option is not the same as changing your sign-in address. If you need to change an address and no option is offered, contact support before creating another account. Keep your current session if it contains purchases you cannot otherwise access.

Currency

Choose your preferred currency, then check the final checkout currency and total before paying. Existing purchases keep their original currency.

Language

Choose the app language in Settings. The help center has its own language selector. If a support reply is in the wrong language, tell us which language you want to use.
