Unit 14 D2
To send a contact from one phone to another you need to select the contact that you want from your contact list, you can then send it via Bluetooth. To do this you need to go onto the contact, go into options and select 'send' and then 'Bluetooth.' This will take you to a list of every Bluetooth device in the area you select the one you want and it will begin to send. The good things about sending things in this way are that its is quite fast, free and easy to use. The negative things are you have to be in range of the person who you want to send things to sometimes it doesn't work if the devices aren't compatible also using Bluetooth can be dangerous because people can access personal files on your phone if you aren't careful. Another way you can send a contact to someone is through messaging you just have to attach the number to a message, this can cost but you can send it to anyone by using a message not just people in close range.
Excellent comparison of the protocols. D2 achieved.
