Received new SIM but shows SIM normt valid when inserted.
Thanks for your post and welcome to our community.
Very sorry that your new SIM isn't working and showing SIM not valid, this isn't good.
It does sound like the handset needs to be unlocked, so we'll see if we can get the unlocking codes and take it from there
So I can do this I'll need to pop you a personal message and grab some details
I look forward to hearing back from you soon.
