When talking about “2-way solutions”, “virtual numbers” and “MO” it’s all the same thing that is being referred to: A mobile number (or a short code, also called premium number) that is set up with our system where you can receive SMS from mobile subscribers.
For example, when you send out messages to your clients you can use your virtual number as the sender. That way, the recipients can reply to your number from their phones and you will be able to receive their replies. Any incoming SMS will be forwarded to you, either over HTTP or SMPP and you can save and view it in your preferred system.
