Hi RBear,
Thanks for your comment, I'm sorry to hear you are also having a few issues with your new SIM and when you tried to contact us regarding this. The last thing we want is to cause any stress or upset with the rollout of our new SIMs.
It seems strange that you were prompted to enter the unlock code again after rebooting your phone. I just want to double check that you were not asked to input a SIM pin, rather than an unlocking code?
If you have misplaced your new SIM card, I can certainly arrange for a new SIM to be sent out to you. Kindly pop me over a private message at the purple envelope with your account details and I'll get that sorted for you.
Many thanks,
Beth
