Apple Music on Android Phone

I'm trying to use apple music on my new android phone. Everytime I try to sign in a report comes up on my iPad saying somebody is trying to use my account in Sunderland. I'm in Gloucershire! I then go through a process which ends up in asking me to confirm my credit card details which but it accepts my card no. epiry date but not my 3 digit security no. Which it says is not valid. Frustrated!! Any ideas.
