Try whatsapp family and friends will have to download it 99 cents but works on 3G and wifi and sends photos no problem.
Best part is it works international at no cost
There's superior and less dodgy security-wise than WhatsApp for free (there's a raft of reasons why I won't touch WhatsApp and never recommended them - just do a general search for "whatsapp security" in your favorite search engine). Everything from
Kik to
Nimbuzz to
XMS to working off of a straight up
XMPP IM account with
Talkonaut, etc., etc., are available though. No shortage of fragmented and diversified methods of swapping text and images on smartphones.
MMS is still the way to go if you just need it to work across all phones, though, and OneMoreBike already got that squared 25 minutes after his first post two months ago.
also note that with prepaid on T-mobile you can turn on unlimited use for only days for which you need it. Since I'm around wifi all day, I use skype and free texting apps on most days. Then I turn on unlimited calling/texting/web if I go to some place unfamiliar or need to coordinate with a group. This brings my total bill to $60 for unlimited skype w/ voicemail + $70 for mobile everything or $130 **yearly**.
You might have more flexibility and possibly save a touch more money going the
Platinumtel route.
