DLR – delivery report

Delivery Report

Delivery report (DLR) is a feature provided for MT SMS, informing the Sender of the current status of the message sent. There are various types of  DLRs, varying from the SMSC DLRs, handset reports or simple bind acks. All of those are provided to give the Sender an opportunity of following up on all the MT SMS sent and catch on any issues in the delivery.

All users of SureM service can receive delivery reports for the message they send. We provide both get/post method in passing on the delivery reports to the clients.

There are two types of delivery reports :

  • Handset acknowledgment
    This report will give the clients the exact information whether the target handset has received the messages or not.
  • System delivery report
    This report will give the clients the notification of the transmission of the messages to the SMSC

Whether you choose SMPP, HTTP or any other type of system integration, we can provide DLRs for all message sent by the clients in real time.

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

OPT-OUT

An opt-out is special feature (required in many countries) added to promotional messages, that allows handset users to unsubscribe from receiving any further SMS from the sender.

Typically, there are several forms of opt-out used in SMS industry :

  1. MO SMS – in this case, the handset user may send a message as a reply to the number the original MT SMS was received from, saying something like “STOP”, “NO”, “UNSUBSCRIBE” etc. This type of opt-out is commonly used in China (TD, N, 0), Russia and many other countries.
  2. Auto-response system – this option is used in South Korea. The government implemented a system where any company willing to send promotional messages must include an opt-out via Toll Free number beginning with 080-… The main point here, is that is the handset user is willing to unsubscribe from receiving any SMS in the future, the process of opting-out must be free for them. The companies renting 080 numbers are the ones paying for the service, so everyone (more or less) is happy.
  3. Link in the body of the message  – “to opt-out from receiving any more news from http://www.ournews.com please go to your personal page and choose the unsubscribe box” – this one is relatively popular as well. A lot of companies, especially e-commerce or online magazines / newsletters are bound to use this option simply because people who subscribe to the services are from different countries and following opt-out regulations for each and every one of them is extremely hard. But, in this case the chance of handset users raising a claim with their mobile carrier and the line getting blocked is very high as well.

In the end, the best way to make sure no laws are broken and the local government is not suing your company for harassing the citizens is to be a step ahead and get all information possible before entering any market with your SMS campaigns.

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.
