''Use it or lose it" is my experience.
Having previously had a UK credit card account closed by the provider due to lack of use despite being in credit !!! i now use my CC a couple of times a year here in Thailand. Prior to use i inform them online of my intended travel to Thailand despite the fact that i live here, that ensures they don't decline the transaction.
I have no intention of informing them that i live in Thailand and thus giving them the opportunity to close the account. I use a UK address that i used to own but is now owned by my son.
My new cards are sent to my son's address in the UK and he sends to me by secure post.
