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.

Korean LMS : similar to concatenated SMS?

What happens when I send a really long message through A2P line? Is it delivered in one piece to cell phone? Or is it cut into parts and delivered as multiple SMS? If so is the order correct?

Every company that needs to send long messages for whichever purpose faces these questions. And truth is – depending on a lot of factors the answer will be different.

Not all countries and networks support the so-called Concatenated SMS (C-SMS, Concats).

Concatenated SMS – a service, allowing delivery of SMS longer than the standard 160 GSM characters in one piece to the handset.

Number of SMS

GSM characters

Unicode characters

1 standard SMS

160

70

2 concatenated SMS

306

134

3 concatenated SMS

459

201

4 concatenated SMS

612

268

Basically, the process involves breaking the message first into multiple parts and then reattached together in the correct order into one message when delivered to the handset.

There is no fixed limit for concatenated SMS, depending on the device capacity it may vary. As for the destination and network – here’s the catch. CDMA networks do not support concatenation. So the messages will be delivered in parts to the handset, which is why for some countries SMS Hub providers always mention that they can not guarantee 100% delivery of the messages over 160 bytes (e.g. USA).

Another case where concatenation is not supported – South Korea. South Korea has a unique service called LMS (Long Message Service). Unlike other countries, for A2P providers Korean message length limit is different :

Message type

GSM characters

Unicode characters

1 standard SMS

90

45

1 standard LMS

91~2000

46~1000

From technical side, the process does not involve concatenation, the message is delivered in one whole piece from the Sender all the way to the handset.

The biggest difference and the benefit of LMS over C-SMS is it’s price. While A2P SMS providers charge the total price as SMS price x (Num. of parts in C-SMS ), Korean providers offer single pricing for LMS. It means, that no matter how long the message you sent is, 200 or 2000 bytes – you still pay the same price, while with C-SMS for really long promotional text you might have to pay 10 x SMS price.

 

Complete Guide to Korean promo / advertisement SMS

In this digital age, more and more people are concerned with the issues of cyber-security and protection of personal information. For companies in the IT-business, as well as any other enterprise, communicating with their customers using the modern technical tools and applications, this subject is extremely hot.

All the countries are introducing strict policies in terms of SPAM prevention to protect their citizens from constant disturbance by the unwanted flood of advertisement messages, and the corporations from highly expensive lawsuits.

South Korean laws (namely, Korean Telecommunications Policy on Spam Prevention, 2014) contain some general guidelines on sending promotional traffic to Korean mobile phone users. The main points to consider are (ref. to picture below) :

  1. Header (광고) – in Korean it means “ad, advertisement” and serves the purpose of notifying the handset users that the message they received is of promotional nature. Whether or not the message itself is written in English, Chinese or any other language – the Header has to be attached by the Sending company in Korean.
  2. Compulsory opt-out – at the bottom of the message, an opt-out option has to be added, so that any handset user could unsubscribe from getting any more promotional messages in the future.

To ensure high delivery rate, the best option is to consult with the SMS provider before sending the traffic. You may contact our specialists to receive full consultation regarding sending promotional messages to South Korea ( and not only)

Sending SMS to Korea

There are three major Mobile Carriers in South Korea : Korea Telecom, SKT and LG U+. These days, following the progress in 4G/5G… development, more and more people rely on various messengers rather than SMS. That is for personal communication.

When it comes to corporate use, SMS is still a very important tool in reaching out to the customers, be it advertisement messages or registration codes for some app or service.

When sending SMS to South Korea, there are certain specifics you should be aware of :

  1.  When sending SMS from abroad, the message length is limited to 90 bytes.그림1
  2. Messages beyond 90 bytes will be delivered in one piece, but not as commonly known concatenated SMS (concat, C-SMS). In Korea, there is a term of LMS (Long Message Service) for messages of 91~2000 bytes.
  3. One of the special headers might be added :
  • [Web발신] (“Sent from Web”), indicating that the message was sent via A2P route.
  • [국외발신] (“Sent from abroad”), indicating that the route used does not belong to a local provider
  • (광고) (“Advertisement”), indicating that message contains promotional information.

IMPORTANT! The first 2 headers are automatically added by the Mobile Carriers and are not counted in the overall byte count. Thus, if you are charged by your provider for adding these extra bytes… Well, let’s say you have a good reason to find a new one!
