Sorry my late response to you.
That activation process did,nt activate even after 24 hrs.
You advised l do a sim swap,which l followed up but that failed too.
This was on 26/04/19.
Luckily on this same day a Friday,l received a used phone sent from a friend.I performed a sim swap and it activated about 10 hrs later that day.
The other failed phone a Nokia 3310 which l purchased from giffgaff has a 12 month Warranty.I am intending to return this rubbish phone to the manufactorers,l,m still under warranty.
Besides the activation failures,this phone is also useless receiving Internet.
Thanks all your good advice.
