SIM cards are to phones, what keys are to a car.
All looks fine from the outside, but you won't be getting far without them!
The main thing to remember when removing your normal SIM card when using a local SIM, is not to lose it!
Three great ways to keep track of your SIMs:
Most of the time I put the SIM in a crevice in my wallet - sometimes between to business cards taped together for more security.
Most of the SIMs I send out come with a normal unused postal envelope, this is a great place to store your SIMs while not in use, but remember not to chuck it out :-)
A SIM card holder
Yes these do exist. There is actually a few different types out there (see attached pic).
They normally have a few different slots to keep all sizes of SIMs, pins and adapters safe.
Some even have slots for your SD cards.
My favourite is the aluminium one.
What is your way of keeping your SIMs and cards safe?
