A sign-in alert can reflect a new device, browser or session. Location estimates can also differ when you use a mobile network or VPN.

If you recognise the sign-in

Check its time and device against what you were doing. You do not need to share the alert or any sign-in code with support.

If you do not recognise it

  1. Open SimFuse directly rather than following an unexpected message's links.
  2. Secure the sign-in method you use. This may mean your email, Apple or Google account rather than a SimFuse password.
  3. Review purchases and payment activity.
  4. Contact support and describe the unfamiliar sign-in so we can investigate available account-protection steps.

If a card payment may be unauthorised, contact your bank promptly as well. Support will check the records before confirming any purchase or refund outcome.
