International SMS Subscription Manager


International SMS Subscription Manager is a WordPress plugin by iGeek inspired by WebAddiCT(s); that allows you to place a widget on your blog where through readers can subscribe/unsubscribe their mobile numbers to receive SMS Text message updates to their mobile phones.

Blog owners have the functionality to send out SMS Text messages to subscribed numbers through the WordPress dashboard and also manage their subscribed numbers and widget options from there.

You can now also send out SMS alert to your subscribers when you post a new blog post.
