This cant be done in single call. You can use hidden button in each row with some command name.
Through javascript call each row button click asynchrounously.

You have to
No of sms send = no of calls to server (asynchronously)
Use Page method to call server side functionality

Do following steps
1.loop through gridview

2. Use page method for send mail
