I have an MTN prepaid sim that I use for data in my laptop and it stopped working but there was network issues at the time so I assumed it was related to that. The sim was still dead this morning so I checked the sms's on the sim to see if there was anything there to explain it and it turns out someone ported the number to the FNB network with no input or authorization from me the number owner, how is that even possible?

Because MTN.

If you stick with them, activate MTN secure on the SIM so that you get an SMS (on another number) or email before the SIM swop happens.

So MTN will allow a port on a prepaid number with zero validation that the post was authorized by the number owner?

The only security they appear to have in place was this sms "MTN has received a request to port your number. If this is incorrect, please reply 1 to this SMS within 45 minutes.". A WASP style negative opt-out, which for all intents and purposes is useless, especially if the port is initiated late at night or you are away from the device the sim is in.

They allow this since the original sim could have been lost/stolen/damaged and therefore you would not have been able to authorise

I highly doubt that is the reason, the number owner can first do a sim swop then authorize the port.

My mistake - I confused SIM swap and number porting. Not sure of the rules around number porting.

Call the new guy and give him a piece of your mind.

post the number, we MyBB forumites will subscribe his number everyday to some cool porn stuff :)
Sounds like a fair option :D

I phoned Mtn's porting support desk and they confirmed that Mtn has zero authorisation controls when it comes to porting on prepaid numbers, other than sending sms notifications to the Sim with a negative opt out. Hard to believe that is the case but it is.

They do have a porting reversal process which I have initiated but I'm not overly hopeful.

Is this the same on all networks?

Imagine the lulz you can have with this scenario, you could even hold someone's number ransom, its bizarre there are no controls in place.

The current ICASA regulation is clear. Operators may not delay a port request in any way. The default Port request response is accept UNLESS you reply saying it's not. It's unfortunately not a choice. I have been complaining to ICASA and networks for years now but no one listens.

The port reversal process is simple. You notify your network of the fraudulent port and they reverse it with in 48 hours to the original simcard.

MTN is the only network that actively tries to warn you about the port.

1st notification is a SMS.
2nd notification is call from MTN system saying MTN has received a port request press 1 to cancel the request.
3rd notification is a call from MTN system saying MTN has received a port request press 1 o cancel the request immediately
4th notification is a good bye message wishing you a connected future and the door is always open at MTN to welcome you back. Good luck

After the last message your simcard gets switched off.


Porting fraud happens mainly for 2 reasons. Banking related fraud when sim swap fails and for easy number numbers like 061 333 3333 which was stolen from me. I reversed the port with MTN 27 times and then just gave up and let the number go. Now it's some Pakistani guys number.

Here in the US, you can port over the phone if you want. A PIN is sent to you and without that, you cannot prove ownership of the number. Any further processing stops at this point. You can take a mobile account to the store and use that as proof also.

The problem with the scenario you just painted is that porting can be initiated by anyone and operators have to execute it regardless. The networks seem to think that sending messages saying that something is happening and you not responding is essentially giving consent. This seems pretty stupid to me and this would be the reason fraud persists.

Porting fraud only happens this way because the process has been designed to facilitate it.

Yes agree so ICASA needs to get they act together. MTN is currently challenging this with ICASA to prevent fraud but I read that they say one network is halting any progress by challenging the changes proposed in the courts. My guess would be Cellc or Telkom. They are the only 2 that benefit from easy porting when the clients of the 2 big network get frustrated and change networks.

MTN also mentioned they have no way of verifying who owns a prepaid number as the RICA docs get sent to some government dept so I'm assuming anyone can stake a claim on a number and they'd be none the wiser.
