Application for IM, Text, and International Calling.
Free or cheap international mobile calls, texts and IM - EQO
very cheap rates for international calls. uses mobile VoIP with great sound quality. Trial version gives you about 100 minutes, then just buy your airtime. even better if you can get the person you are calling to get the app, you can talk to other EQO members free (it will use airtime, but to call anywhere in the world and use only ur anytime minutes aint bad)
even if you never call out of the country, it will also do Instant Messaging with AOL, MSN, Yahoo!, Google Talk, ICQ, and Jabber all free.
ive tried the application and am very pleased, about 20% of my calls are to Europe and have had no problems.
