Is sending photos on iphone 4 free? On pay as you go?

Curious

Sending it through text will cost more than the average text.

If you email it using Wi-Fi its free. But if you use your own network internet it will cost u money. And if you use mms for picture msg it will cost you to…
best way is use Wi-Fi and email it to your friend.

Depends how,
Sending it via 'MMS' is basically a normal text message with an inserted picture and costs a little more than your average text price.
Sending it via email is technically free but you have to pay for internet
Sending it via bluetooth is free if you have it but you will have to pair deviceswith the person to receive the picture through their bluetooth code etc.

Merry Chriistmas!

If you send it through mms it'll will cost between 25p and 40p

iMessages are free your iphone will lower the image size to 1mb though

Emails are also free.

Hope this helps
