SIM card sizes explained.
When you get a SIM card from us it actually contains all three sizes (Standard, Micro, Nano). You simply choose the size you need, snap it out from the perforated edges, and insert it into the SIM card tray of your phone. Make sure you're certain of the SIM card size before you do this. Check the handset manual if you're not sure.
How to find out your SIM card number.
Your SIM card number is the 19-digit number printed on the SIM card holder, under the barcode.
If you don’t have the card holder any more, don’t worry - the number’s also printed on the back of the SIM card itself. It’s an 11-digit number, and you just need to add ‘89442001’ to the start of it if you need to input it somewhere.
How to get a PUK code and unblock your SIM.
If you enter the wrong PIN to unlock your phone screen too many times, you might block your SIM. If this happens, you’ll be asked to enter an 8-digit PUK code to unblock it.
To request a PUK, contact one of our Live Chat agents.
Be careful when you get it, because if you enter it incorrectly 10 times, your SIM card will be blocked permanently!
