MNP

Mobile Number Portability (MNP) is a service that allows you to switch over to another mobile service provider while retaining your existing mobile phone number.

Mobile number portability is implemented in different ways across the globe. The International and European standard is for a customer wishing to port his/her number to contact the new network (recipient), which then sends the number portability request (NPR) to the current network (donor). This is known as “recipient-led” porting. The UK and India are the only exceptions to implement the donor-led system. The customer wishing to port his/her number is required to contact the donor to obtain a code (Porting Authorisation Code (PAC) in the UK and Unique Porting Code (UPC) in India) which is then given to the recipient network. The recipient continues the porting process by contacting the donor with porting code. This form of porting is known as “donor-led” and has been criticised by some industry analysts as being inefficient, though prevents MNP scams. It has also been observed that it may act as a customer deterrent as well as allowing the donor an opportunity of “winning back” the customer.

South Korea introduced MNP more than 10 years ago, in 2004.

To know if your country has the MNP implemented, the easiest way to check is ask your mobile providers. MNP gives mobile carriers a good opportunity to lurk in more customers, as retaining one’s mobile number while switching to a better option of service is indeed very attractive.

Here are some of the websites you may use to know about different countries’ policies on MNP:

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.

Auto-Calling System (ACS)

Auto-Calling System (ACS) – a type of voice call service, automatically dialing the end user and playing the provided record of the message.

ACS service is widely used :

  1. To cover the areas, where SMS reception can not be guaranteed
  2. When the end user is in roaming
  3. For users with disabilities, preventing them to read the messages

In general, ACS is a good way to improve delivery rates if used in combination with SMS.

Below you may see the flow for ACS service at SureM

Benefits of ACS

  • A subscriber can still receive the verification code when a text message cannot be delivered.
  • A subscriber is given a choice to make to receive a voice call instead of a text message.
  • Speech can be recorded in different languages to suit the recipients that makes it much easier and more convenient for the recipients.

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

70

2 concatenated SMS

306

134

3 concatenated SMS

459

201

4 concatenated SMS

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)
