The SMSGlobal SMS Plugin allows WordPress Administrators to send SMS to their users through the SMSGlobal Gateway.
I tested SMS to Norway and it works fine - this is the only SMS plugin that works for Norway among they I have tested. Remember the country code. You need an account at SMSGlobal.com. They send SMS to all contries very cheep. The plugin uses their SMS gatway, no other gateway is needed.
Some wishes to improvements:
- SMS notifications about new posts should contain name of website and link to post (for smartphones), not only post-title.
- A widget for visitors to subscribe to notifications would be nice.
