I have a very, very old SIM card. It’s from the 3G era, which means I miss out on my phone’s 5G capabilities. However, when I went to buy a new card I found out you’re required to take a selfie and send to the telecom company alongside your ID and email, which is creepy enough to keep me using my 3G SIM…
Maybe you can request a new card but under the same number? In my country we can request for a new card that way, though we didn’t need to take a selfie when buying a new number, just have to register your name and ID(quite old fashion but the rule is made in pre-smartphone era to combat scammer)
I’d have to go to a telecom store to do that in person, which I don’t really have an issue with, except that it may take a whole afternoon on a queue waiting for my turn.
Anyway, I rarely use mobile internet and when I do, it’s mostly for text messages, so I don’t feel a pressing need to upgrade.
