for those of us who have T-Mobile and tired of paying US$0.15 per international SMS, you may consider using the smsbug software.
The may be the alternative for sending Int'l SMS, I got this info from someone in Howard forum and it costs about US 3.75 cents per SMS.
Go to http://www.smsbug.com 1. download it from your mobile phone
2. register your phone
3. they will send you 20 FREE SMS credits to try out the product.
4. you can buy more credits afterward (3EURO for 100 SMS...)
