Relay 1 (ProWebSms expansion)

This is an expansion app which can not operate without the ProWebSms app. So please install first the ProWebSms app then install as much relays as you need.

Each relay (called also expansion) boosts the SMS sending rate of your main ProWebSms gateway App by:

• 60 SMS / hour on Android 4.1, 4.2, 4.3, 4.4, Android 5 and recent versions

• 100 SMS / hour on older versions of Android.

Without an expansion Relay, ProWebSms is limited to 30 SMS per 30 minutes (on Android 4.1 and greater) to avoid a confirmation popup from showing.
