When I moved from the UK to USA it was the same in reverse. I had just got a new phone and number and immediately started getting spam calls and texts. I asked my colleagues how I could report or block these and they didn't really have an answer. OFCOM in the UK largely deals with spam and when I've had spam it's usually been that it comes from outside the UK but will still eventually get blocked
