I believe O2 used to, believe it used 2-3 of your standard free messages. Not sure if that's the same policy now or not
On my contract o2 take 5 standard messages for 1 picture message (or overseas text) but they dont do it anymore as they have been trying to get me of my particular tarrif for ages!
If you both have data it's probably going to be easier to share with whatsapp
I agree with this. Use Whatsapp.
How does "Whatsapp" work?? Do both the sender and receiver need to have it installed??
Think of it as ICQ/MSN Messenger/AIM etc... works on any mobile OS and is free (for a year) and as it just sends the messages over your data connection they are free too. can be used to send pictures as well as text etc...
