through which provider you’re calling.
SIM card:
A SIM (‘Subscriber Identity Module’) is a
small card containing a chip. The phone
number is programmed in this chip and it
also allows you to store several numbers
and messages, so you can take this infor-
mation with you when you install the SIM
card into another phone.
SIM cards can be supplied with the phone
or you can purchase them separately. SIM
cards are provider-specific.
