even though i dont like typing a lot of sms's,they are charged a lot in my country...i send basically 50 sms's for a month and i want a app that will work with wi-fi and to send free sms.but not like "viber"an app that only sends sms to phones that have that app installed,i want an app that will send sms no mater if the other party is connected to the internet or have that app installed...
