You can use your phone to make, receive, and keep track of voice calls, and 

send text messages (SMS, Short Message Service) and MMS (Multimedia

save a new number in Contacts. To access the Phone screen, do any of the 

following:

  Enter the phone number by pressing the keys on the keypad.

Most Subscriber Identity Module (SIM) cards are preset with a personal 

identification number (PIN) that is provided by your wireless service 

provider. You need to enter the PIN whenever you use your phone.

  Enter your SIM PIN when prompted and click Done.  

Note 

If your PIN is entered incorrectly three times, the SIM card will be blocked. If 

this happens, you can unblock it with the PIN Unblocking Key (PUK) obtained 

from your wireless service provider.

You can change the SIM PIN by clicking Start > Settings > Security >

None in the Ring tone list mutes the phone. For more information about 

sounds, see “Choose how to be notified about events or actions”
