Almost all countries require official authentication to activate a SIM card. This seems to me as a huge privacy problem, if the country can track sim cards across cell towers and connect them to a person. It seems like a dystopian system, that we litterely can not hide from our governments without turning off our smartphones. It seems incredibly unnecessary to me and just sets up the system to be abused.
Or do I understand something wrong?
What can we do against this? There are some sim cards that can be bought second hand, but they will not be a long term solution.
I think it’s actually the other way around. BECAUSE phone numbers are linked to our accounts and identities, it makes us vulnerable to SIM swapping. They should only be used for calling and texting people, nothing more. But nowadays we need to link our personal details to them, our accounts, which introduces this vulnerability because then it creates this incentive for an attack
If you live in a country where carriers are required to identify phone numbers and do identity checks for SIM swaps they’ll never, ever, allow someone to get a SIM with your number without providing valid govt ID. That’s why it solves the issue and its safe. Just look at the numbers / stats and you’ll find that the SIM swapping attacks happen on countries where no identification is required.
