The current low security procedure should have a longer hold time. I did say that the mobile networks should introduce higher security processes for those wanting better turn around times.Who are you to decide that my number must be unavailable for so long?
(not that my SIM is linked to my primary banking at all)
No, the solution is to not keep your savings with the same bank/institution as your transactional account (unless very secure online, like Capitec, and even then, don't keep the savings in your cards account , rather in a sub account, then nothing much can happen even if they steal/rob/swipe your card and pin).My solution have always worked well for me. Never have any money to steal. There problem solved.
No, you won't. There will be investigations and legal process where you can prove your innocence.If your SIM is swapped and then used to call in a bomb threat to parilment, to set off a cellphone bomb, or to download child pr0n, or any other illegal activities YOU will be guilty of it.
Banks who do check IMSI, like ABSA, get the IMSI from the MNO when you respond to the push USSD message. This is functionality that exists on all MNO's, they just don't all pass the IMSI to the bank. AFAIK there is no way using standard USSD or SMS that the MNO would get your IMEI as wellBanks already pair your phone and app with your internet banking service. Why not use the IMEI and IMSI when processing USSD prompts?
