Good Afternoon johnp101,
Thanks for your post on our Community Forum and a very warm welcome to you!
Sorry to hear you've been struggling to activate the SIM card.
Have you been able to solve this since your most recent post or are you still struggling with this?
Can you tell me if you've been able to try inserting the SIM card into a different handset to see if this will help with the activation process?
Kindest regards,
David_Bn
