Clockwork SMS Notfications free WordPress plugin

Free: Send your subscribers SMS messages when you publish a new post via free email to SMS gateways. Many mobile providers throughout the world provide free email to SMS gateways, which this plugin uses to send the SMS notifications. Because the gateways are free, some mobile providers do not prioritise their maintenance or publicise their existence, this plugin uses a central list of known working gateways which is provided by SMS service provider Clockwork as a service to the community. Paid: Send your subscribers SMS messages when you publish a new post through Clockwork SMS. Clockwork is a paid SMS gateway. We charge 5p per SMS in the UK, and deliver to over 900 networks in over 200 countries worldwide. It’s free to upgrade the plugin – you only pay for the SMS messages you send to your subscribers. This also simplifies the widget so that instead of having to choose their country and network, your visitors just have to enter their phone number – and we do the rest.
