UK 2016: https://www.theguardian.com/money/2016/apr/16/sim-swap-fraud-mobile-banking-fraudsters https://www.theguardian.com/money/2016/apr/16/sim-swap-fraud... >When Sims rang EE, it soon emerged that someone posing as his wife had managed to persuade the mobile network to activate a new sim card >Sims says that when he contacted his bank, Halifax, the call centre told him it is handling hundreds of sim scams every day, making it the fastest growing fraud in the country – although Halifax later disputed this figure. On the other hand I'm sure I saw something about banks etc being able to subscribe to services that would give them background information about a mobile number (ie if the number has been recently ported).
