Hi I restarted my phone and now its asking for my sim card unlock pin I have one more try I have found what I think must be the number. However it has both upper case and low case letters in it how do i achieve this on the keypad.
Is it a new SIM card you've got there? If you've had it recently the default SIM PIN will be 7890. If not it would usually be comprised of numbers and not letters.
Hope this helps but any questions please let me know.
