Effect of Photocopying on SIM card

Since I tend to move from country to country quite a lot, I have SIM cards from 3 different countries. At any given time I have one of them in my phone, depending on which country I’m in, and I use some sellotape to stick the other two to the back of my passport. That way I’m sure to never lose any of my SIM cards, and since I always travel with my passport it means that I can stick the relevant card in my phone whenever I’m in a new country.

So anyway, lately I’ve been doing quite a lot of paperwork and that has resulted in my passport getting photocopied quite a lot. I’m wondering, is there anything a photocopier can do to the SIM cards that are stuck to the back of my passport? Will I lose any data or will they stop working?

No - it’s basically just light - it will not have any effect on your SIM card.

I’m assuming you mean laying it flat on glass - not having attached to a piece of paper that gets fed through rollers into the copier mechanism.

I now have 3 SIM cards–1 for China, 1 for Hong Kong, and 1 for South Korea. At any given time, I have two of them in my cellphone.

Huh? How do they fit in the phone?

Anyway, DataX has answered my question. Cheers!

Dual SIM phones are quite common here in Asia. You put one SIM in one slot and the other in another slot.
