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?
