Besides making calls from the phone dialer screen on HTC Status, you can tap a number in a text message or email to call, or press a single number on the keypad to quickly call a contact.
Most SIM cards come with a PIN (personal identification number) set by your mobile operator. If you’re asked for a PIN, enter it and then tap OK
. If you enter the wrong PIN three times, your SIM card is blocked. Don't worry. Just contact your mobile operator and ask for the PUK (PIN Unblocking Key).
