iPhone Calling

Have people asked you why you're blocking your phone number? The iPhone can automatically turn off your caller ID when dialing out. Chances are, if your iPhone number is blocked on other people's phones this setting is engaged. To show others your phone number follow these steps:

1. Navigate to Settings -> Phone -> Show My Caller ID
2. Select ON

Now when you call, devices capable of reading the caller ID will display your number instead of a "Blocked" message.

Wideband audio was announced at Apple's iPhone 5 media event, and 20 carriers are expected to support the technology at launch. Unfortunately for US customers, the major carriers AT&T, Sprint and Verizon are not included in this list.

Remember people with Nextel phones, beeping everywhere and chatting just like they were using a portable two-way radio? Now you can simulate this fun with your iPhone thanks to a variety of apps.

Push-to-talk (PTT) capabilities are possible using many apps, including the following software available on the App Store for free:

1. HeyTell
2. iPTT push-to-talk

Dialing an international number on the iPhone requires the "+" symbol ahead of the phone number. The Contacts app can store these numbers so they can be dialed automatically.

Create a contact or navigate to an existing contact and select the phone number field. To add "+" when storing an international phone number, touch the button in the lower left hand corner of the keypad marked "+*#". This will switch the number keypad over to symbols and the "+" sign will appear where the 0 (zero) button was.
