Your post was blank @StephenO2900 and the subject line doesn't really explain your question/issue clearly.
If you want assistance from the Community Forum then you'll need to provide more details and context than that and explain/describe your issue/question clearly and in detail.
Did you successfully activate your SIM?
Is it installed and working in your phone and you're getting a connection to the 48 network - I.e. signal bars?
What exactly is/isn't working?
Incoming/outgoing calls?
Incoming/outgoing texts?
Mobile data?
What happens when you try to use outgoing services?
Any error messages?
What exactly do you mean by "not able to activate plan"?
Monthly membership plans don't need activation - you just buy one and it starts working.
If you need to contact 48 support about this then see the links in my signature below.
