Just imagine I found a service that can port your phone number to my computer and all I'd need to do is tell a cheeky little lie to gain access to all your text messages and be able to send text messages without you even knowing I've done it .. I ' d be able to get inside any accounts linked to that number if I tried hard enough including apps like Whatsapp .. What would I see and what would I do if I had access to your phone number ?
