My wife and I are on a BT family Sim contract , we have 3 phones , one each and one business number.
Today I received 2 work related calls meant for my wife’s personal number on my personal phone in quick succession, 10 mins apart. My phone is an Apple , my wife’s is a Samsung. The callers were expecting my wife to answer. Neither caller has my number and never has. There is nothing suspicious about the calls , just work related , but we cannot work out why the calls came to my phone instead of hers ? Different OS , Android and iOS , so no software or app connection. The only connection is the BT family sim contract, can anyone explain this worrying behaviour.
