Using Your Phone’s SIM Card
Before using your phone’s GSM capabilities, you must acquire and
install a Subscriber Identity Module (SIM) card. This card identifies
your phone to the GSM network(s) in which you are traveling, and
can also store personal data including a phone book that is kept
separately from the phone’s internal Contacts directory.
To order a SIM card:
ᮣ Call Sprint PCS International Customer Solutions at
1-888-226-7212.
