Wi-Fi For IPhone.

Having access to Wi-Fi on an iPhone allows you to minimize the impact on your data plan and, ultimately, your phone bill. Being able to use Wi-Fi for Internet access when you are near an available wireless network means you can use online services without worrying about how much data you're using up. Accessing Wi-Fi on an iPhone is straightforward, as the user interface is designed to give you control and ease of use.

To find available networks in the current area for the iPhone to connect to, choose "Settings," then "Wi-Fi" and any networks detected will be displayed. Tapping on a network will make the iPhone attempt to make a connection to it. The "Wi-Fi" icon will appear in the status bar when you are connected to a network, with the number of bars indicating the strength of your connection. The connection strength depends on the network itself and on how far you are located from it.


Bluetooth.

Tap the entry for the Bluetooth accessory when it's detected by the iPhone and displayed on the screen. If the accessory requires you to enter a passkey to complete the connection, enter the number when prompted by the iPhone. The iPhone can now use Bluetooth to operate in conjunction with the accessory.

SMS

Cellphones are not really that new anymore, they have been around for a long time and new models are being released weekly, producing something more advanced and capable every single time. sms stands for short messaging service and it is when a text message is sent over a wireless phone system. The message then appears on the recipient’s screen of their cell phone. Normally text messages can go up to 160 characters but that is for a 1 page SMS, you can go to more characters but it is going to cost for every SMS you send. For example, if you send a SMS that has 480 characters, you will be charged for 3 SMS’.

Sending or receiving text messages requires no phone calls and when you receive a SMS, you will not be charged, only the person who sends the SMS will be charged.
