Please note: Messages longer than 160 characters (taking into account the symbols that count as 2 characters. For more information on symbols that count as 2 characters, click here.) use multiple segments and therefore use more credits. The cost per message is multiplied by the number of segments the message uses. To enable long message support, click here and log in with your WinSMS username and password then click on "My Profile"
Click on the E-mail to SMS tab.
Click on the "Enable Long Messages" button
You are now able to send long E-mail to SMS messages.
Please note that your e-mail signature is part of your message and you should remove it it or turn it off so you do not use unnecessary WinSMS credits.
