In 2017 I purchased a phone with GiffGaff. I have gone to Top Up and it says the SIM needs to be activated but has previously been working fine. Please can somebody help me with this issue. We have a voucher ready to top up the account. 

I have entered the 13 digit code from the SIM card and it doesn't work.

Hi @martinradford try dialling 43430 or using the giffgaff app to redeem your voucher.


Otherwise please try using another browser or device.

Hi, the 43430 number doesn't work as I have no network?

Have you used the SIM within the last 6 months for an outgoing call or text, or a mobile data connection?

I do not work for giffgaff, so cannot check anything on your account. This is a public community - please do not post any personal info.
