Non-Latin based languages, like Chinese, and also emojis use a different encoding process called Unicode or Unicode Transformation Format (UTF-8). It is meant to encompass all characters for efficiency but has a caveat. Each unicode character is 16 bits in size, which takes more information to send, therefore limiting SMS messages to 70 characters. Messages that are larger than 70 characters are also concatenated. These messages can fit 67 characters, and can be concatenated up to 4 times for a maximum of 268 characters.
To learn how your message can be improved, it’s important to analyse the results. Which parts of your message are not performing as well as expected? Is the open rate lower than expected? Or are people opening your message, but not taking any further action based on the contents of the message? Your analysis will tell you which parts of your message can do better and will help you to formulate your goal.  
One key criterion for provisioning is that the consumer opts into the service. The mobile operators demand a double opt in from the consumer and the ability for the consumer to opt out of the service at any time by sending the word STOP via SMS. These guidelines are established in the CTIA Playbook and the MMA Consumer Best Practices Guidelines[17] which are followed by all mobile marketers in the United States. In Canada, opt in will be mandatory once the Fighting Internet and Wireless Spam Act comes in force in mid-2012.

There is no other method that comes close to SMS in terms of reach and reliability. And that goes for their open rates as well. Clients can easily skip over a social media or mobile app push notification that appears briefly on the screen and then disappears. Emails are rarely even opened and when they are, it may be long after the event or promotion you were advertising took place.

Long codes are normal 10-digit phone numbers that can be used to send and receive text messages. They’re the cheapest option for a dedicated number and can be set up in just a couple of minutes, making them a popular choice if you’re on a budget or in a hurry to get started. The biggest advantage of long codes is that they support both domestic and international communications. They’re perfect for global businesses or companies who aspire to be one. However, if the success of your SMS program depends on customers initiating contact with you, you should consider a short code instead.
Mobile advertising has become more and more popular. However, some mobile advertising is sent without a required permission from the consumer causing privacy violations. It should be understood that irrespective of how well advertising messages are designed and how many additional possibilities they provide, if consumers do not have confidence that their privacy will be protected, this will hinder their widespread deployment.[40] But if the messages originate from a source where the user is enrolled in a relationship/loyalty program, privacy is not considered violated and even interruptions can generate goodwill.[41]

These are dedicated memorable shortcode numbers which means that you’ll be the only company that uses the number, allowing it to become synonymous with your brand ensuring consistency and brand recognition. You can either purchase a random short code which means that an available short code number will be assigned to you, or you could opt for a vanity short code which means you get to choose the number you want to use.

For a more cost-effective solution, you can register a keyword on a shared short code, which means you will be assigned a unique SMS keyword but you will share the short code with other businesses. These short codes are great for competitions or lead generation for example, where customers can SMS your keyword and their details to the shared number to enter or request a quote or more information about your products and services.

Marketing through cellphones' SMS (Short Message Service) became increasingly popular in the early 2000s in Europe and some parts of Asia when businesses started to collect mobile phone numbers and send off wanted (or unwanted) content. On average, SMS messages have a 98% open rate, and are read within 3 minutes, making it highly effective at reaching recipients quickly.[4]
Kaplan categorizes mobile marketing along the degree of consumer knowledge and the trigger of communication into four groups: strangers, groupies, victims, and patrons. Consumer knowledge can be high or low and according to its degree organizations can customize their messages to each individual user, similar to the idea of one-to-one marketing. Regarding the trigger of communication, Kaplan differentiates between push communication, initiated by the organization, and pull communication, initiated by the consumer. Within the first group (low knowledge/push), organizations broadcast a general message to a large number of mobile users. Given that the organization cannot know which customers have ultimately been reached by the message, this group is referred to as "strangers". Within the second group (low knowledge/pull), customers opt to receive information but do not identify themselves when doing so. The organizations therefore does not know which specific clients it is dealing with exactly, which is why this cohort is called "groupies". In the third group (high knowledge/push) referred to as "victims", organizations know their customers and can send them messages and information without first asking permission. The last group (high knowledge/pull), the "patrons" covers situations where customers actively give permission to be contacted and provide personal information about themselves, which allows for one-to-one communication without running the risk of annoying them.[45]
By now, you have a pretty clear idea of what you need to improve to reach your goal. But how are you going to do that? You need to form a hypothesis about what you think would work better than the message you have now. You may already have some ideas about things that might work based on previous experiences. Or you may have no idea where to start. You can start with evaluating some email/SMS marketing best practices and see whether these would fit for your business. You will only know whether these are suitable for you once you start testing, but it gives you a solid starting point.
