2-way SMS

2-way SMS service – a combination of MT and MO services, allowing the CLIENT to transmit messages and receive replies from the End User.

The service is provided through a virtual number, issued by the provider. Depending on the destination country, virtual numbers can be presented by long codes, short codes or standard phone numbers.

Example:

  1. Short code : 114, 4565,.. (usually up to 5-6 digits)
  2. Long code : 0133-xxxx-xxx (Korea) (special virtual number, does not look like a real phone number; issued by designated entity in each country)
  3. Standard phone number : 7-914-xxx-xx-xx, 82-10-xxxx-xxxx (in some countries Mobile carriers provide numbers similar to standard mobile numbers)

2-way service is widely used for various purposes:

  • Advertisement opt-out (unsubscribing)
  • Customer care lines (*with TOLL-free numbers)
  • Polls and surveys
  • Marketing campaigns

IoT utopia : South Korea

The per-capita penetration of devices associated with the Internet of Things is highest in South Korea, at 37.9 per 100 inhabitants, according to a study on the industrial internet by the World Economic Forum. It’s followed by Denmark, Switzerland, the US, the Netherlands and Germany.

No surprise then, that with the total population of 51.5 mln people, South Korea is getting closer to the figure of 60 mln mobile subscribers (forecast by the end of 2016).

20 years ago you could hardly find a person with a mobile device, today it’s nearly impossible to find someone without one. South Korea, being the country at the forefront of developing new communication standards and optimizing / creating new devices to make “The Fifth Element” a reality, is the very example of modern IoT conception.

IoT

Every device from mobile phone to rice-cooker or fridge in Korea now has its own IP and can accept orders from the owner any time. It can now talk, knows our schedule better than we do and has become a substitute to friends, family, professional maid and what-not for many people.

To keep up with the latest trends and enjoy the advantages of the miracles of computer science to its fullest, at the very least every person must have a mobile device – or in case with Koreans, the average of  1.17 devices per person. And that is smartphones only! In reality, no matter where you go – subway, park, restaurant or a movie theater – people everywhere have devices glued to their hands.

In this era, IT companies, especially the customer support lines of those in telecommunications business, are busier than 911 in case of emergency with the network. Among the variety of services and products, SMS business has now taken a great shift from the prime means of interpersonal communication (P2P) to one of the tools for reaching out to customers with just one click on manager’s keyboard (A2P).

MO SMS

MO (Mobile Originated) – message transmission from a handset device to a client (program) or application.

MO service is often used as part of 2-way SMS service (MT/MO combination).

In this case, companies send MT message first and receive a response from the end user.

Example :

MT : To unsubscribe from this newsletter reply STOP.

MO : STOP  (it will automatically be forwarded to the MT sender)

The service provider is assigning a certain Sender ID (long or short code) and the Client might receive MO messages from the end users, sent to the designated Sender ID. The procedure looks similar to the standard MT flow, only the other way around, with message originating on the mobile device.

The most common cases for MO service usage are :

  1. Talent show voting (“To vote for Kelly send KELLY to 1234”)
  2. “Request a song” shows
  3. TV Homeshopping (“Send us the item number to receive a free consultation”)
  4. Subscribing to newsletters

MT SMS

Basic MT flow

 

In reality though, to be able to send a message between a PC (or other app) and mobile handset, you would need to use messaging service of SMS Gateway Providers. And the overall flow would look a bit more complicated :

The message is sent from the CLIENT’s app or server to SureM’s platform, forwarded then to the respective carrier and all the way to the handset.
