2-Way SMS Messaging

2-Way SMS Messaging allows to send and receive SMS through a web messaging paltform with the help of APIs or complete solutions. Two- Way SMS incorporates outbond Mobile Terminated (MT) and inbound Mobile Originated (MO) SMS.

2-Way SMS messaging is done with the usage of short codes or virtual long numbers known as virtual mobile numbers. The main differentiation between short codes and long numbers in 2-way SMS is the length of the number; while virtual mobile numbers look like a common phone number, short codes have between 3 and 6 digits and user is able to remember it faster.

Short codes are used only on a national level because different countries have different regulations and requirements concerning them.
