C900 SIM Card
A SIM (Subscriber Identity Module) Card is a portable memory chip used in cell
phones that operate on a GSM network. If the SIM card has been activated by the
service provider, the customer only needs to insert the SIM card into their phone
for use. SIM cards hold information, such as cell phone number, phone book
information, text messaging and other data. SIM cards can be easily transferred
from one mobile to another.
Note: Some SIM cards operate on a pre-paid plan and minutes may need to be
purchased.
