Buna andreea, so, as you need free International sms service i will recommend you those which really worked for me, here are few sites..
1. http://www.fastsms.name/index.go?re… in this site when you register you get 10 sms free as credits for international service sms, but after registering go to option > win free credits < in this you get a link give them your friends and when they register through that link, you can earn unlimited sms with that. this service really great and it give you delivery reports too.
2. http://www.wadja.com… in this site when you register you can send many unlimited international sms to your friends but disadvantage is that, it let you write just 1 and half line, this service not that good, but works for some extent.
3. http://www.ammas.com… < yes this site in which you written your question. when you register this site, you get 2 international sms free. And go to Mobile/sms option and click earn AA$ and free sms for inviting your friends when you click that, you can login your yahoo, msn, google and you can give invitation to your friends if 100 accept this you get 100 free international sms. Or if you give answers to the questions here and ask questions you earn AA$ and you can conver AA$ for free sms.
