Say what a SIM card does
Which part of the phone is carrying your number.
A SIM is a small chip that tells the network which number this phone has, and which account to bill.
Move the chip to another phone and the number goes with it. Photographs stay behind.
Key points
- A SIM is the chip that tells the network your number
- Photographs and messages live on the phone, not the chip
What to remember
- The number belongs to the chip, not the phone around it.
- The SIM carries the number. The phone carries everything else.
Try this
Open Settings, then About, and find Phone Number. Seeing your own number written down is worth it.
