What do you mean?
Memberships don't need "activation".
What does your My48 account dashboard say about your current membership plan status and expiry date?
What exactly is/isn't working for you?
Connection to the 48 network - i.e. signal bars, incoming/outgoing calls, incoming/outgoing texts, mobile data?
When was everything working ok for you last?
If you need to contact 48 support about this then see the links in my signature below.
