member49467 Hi Wes. When was that SIM last used? If it hasn’t been used for 6 months, that SIM will have been deactivated, hence the activate SIM message on-screen. Please view the article below to find out how to keep your SIM card active and how to avoid SIM card deactivation.

If your SIM has been used recently and is still working, do you have more than one giffgaff account? If you do, perhaps you are trying to log into the wrong account?
To avoid any doubt, please view the information listed on giffgaff’s lost password page to help you obtain your correct account login details.
- If you have forgotten your member name (or you’re in any doubt), text membername to 43430 and giffgaff will text it right back to you.
- If you can’t remember which email address you used when you joined, text forgotten to 43430.
