setting a pin or password to protect against Sim card swap attack

Just type “talk to a person” (several times), to avoid the 24/7 chat-bot and speak to an adviser, @Daves.  

Thanks Rookie

I’m sorry your answer doesn’t help on this occasion.

Tom this is what I am trying to do because of this threat. If the pin you provided for telephoning your staff is enough then fine if not how do I set this up?  Your website doesn’t cover this as far as I can ascertain. Thought this would be a known issue by idmobile but it’s proving to have taken a lot of my time and having spent an hour the other day on chat it seems quite difficult or impossible to find a solution.

Protect yourself from a SIM card swap attack

• Set up a PIN or password on your cellular account. This could help protect your account from unauthorized changes. Check your provider’s website for information on how to do this

I still don’t quite understand. The information came from Malwarebytes monthly newsletter. When I got that I wrote to idmobile and whilst the guy was very helpful he gave me a link to a site which just stated exactly the same as the message above. So I gave up with idmobile and thought I would try the forum as I thought I might get someone who knew about the issue to tell me how to set it up.

i do have a customer service pin on my idmobile account and I want to know if this is what the recommendation is on Malwarebytes instruction or do I have to do something else to prevent against this fraud method?

If you want to enable the SIM PIN then on iOS all you need to do is the following:

Settings > Mobile Services > SIM PIN > Enable > Enter default SIM pin.

On Android, the process varies depending on the Manufacturer.

But this is not what you’re asking. What you’re discussing in your original post is the ability to set a PIN on your iD Mobile account preventing anyone from ordering a replacement SIM without first entering or confirming the PIN. This is not possible with iD Mobile.

STOP!!! Your service PIN is not a SIM PIN!

I can’t remember what the default SIM PIN is for iD Mobile as it’s been a long time since I changed mine. It was either 0000 or 1234. I forget which.

Before you try again, you need to request a PUK code from customer services. If you enter a SIM PIN incorrectly 3 times, the SIM gets blocked, and you need to enter the PUK code to unblock it, and then you can reset the SIM PIN to one of your choosing. A PUK code is unique to each SIM, so only iD Mobile can provide you with it. Enter an invalid PUK code 10 times and the SIM is permanently blocked and will have to be replaced.

Make sure they give you a PUK code, the agent might get confused. A PUK is 8 digits in length. e.g. 12345678

FYI - When I asked for one a few years ago, the PUK code they gave me never worked and the SIM got blocked so be careful.
