Thanks for chatting with me and confirming your details via PM @Emma9212 😊
I have now reset the pin for you, you should shortly receive a text confirming this. Once you get this please follow the instructions to reset this on your end.
As you are also abroad, just wanted to make you aware we have a roaming hub here should you need any questions about using your phone abroad answered.
Let us know if you need any further support, we will be happy to assist.
Regards
Nathan
