I am having a lot of unusual activity on my cellphone, double debits on the bank accounts etc. Its a mission to sort out but easier to pick up with this SMS notifications facility. Then it occured to me I show my cell number on all my E mails, any docs I fill out, in fact the whole world knows my cell number & thats the one I use to get the notifications & codes when I want to do account maint, change limits transfers etc

. So its easy for the fraudsters to pick up on my cell number & do the SIM swap, change my limits, open beneficiaries & transfer my life into the blue yonder.
So softness

says in her infinite wisdom, why not send all the notifications etc to a mobile number that is ONLY used for that purpose. Only the bank knows that number and because its an old sim card from a year ago no one else knows it exists. If there is fraud it must come from the bank.
SO I now have a notification number NO one else knows....
Makes you think doesn't it? Just my ZIM 2c worth
