"space, time and cost constraints of text messaging. This follows from how early SMS permitted only 160 characters and that carriers began charging a small fee for each message sent (and sometimes received). This, together with the difficulty and inefficiency in creating messages led the desire for a more economical language for the new medium. It also shares some of these characteristics with Internet and Telex speak following from how its evolution is rather symbiotic to the evolution of use of shorthand in Internet chat rooms. Likewise, such a change sought to accommodate the small number of characters allowed per"
"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. Although this may sound complicated, most SMS service providers will have a character counter built inside"
"senders that have a subscription for a limited pack of sent SMS, smartphones should display the number of character used and the maximum number of characters in the composed SMS. When a message exceeds this maximum, the message will be sent as multiple successive SMS containing parts of the message (each one containing a sequence number, which also uses a few leading characters in each part); these parts will be reassembled later by the recipient. Some GSM smartphones will alert the user about the number of SMS messages needed to send the message, when it requires more than one. Since"

Longer messages may be sent, but will require a continuation prefix and a sequence number on subsequent SMS messages (these prefix bytes and sequence number are counted within the maximum length of the 140-octet payload of the envelope format). When there are 1 to 6 spare bits in the last octet of a message, these bits are set to zero (these bits do not count as a character but only"

The message size will then determine the number of SMS messages that are sent, which then determines the amount of money spent on marketing a product or service. Not all characters in a message are the same size. A single SMS message has a maximum size of 1120 bits. This is important because there are two types of character encodings, GSM and Unicode. Latin-based languages like English are GSM based encoding,"

Due to representations received from some of the service providers and consumers, TRAI (Telecom Regulatory Authority of India) has raised this limit to 200 SMS messages per SIM per day in case of prepaid services, and up to 6,000 SMS messages per SIM per month in case of postpaid services with effect from 1 November 2011. However, it was ruled unconstitutional by the Delhi high court, but there are some limitations. A"

Because of the nature of the SMS, the chance that these parts of the SMS message arrive in order is slim and therefore a strategy is implemented in order for the original long message to be reconstructed. One way of sending concatenated SMS (CSMS) is to split the message into 153 7-bit character parts (134 octets), and sending each part with a User Data Header (UDH) tacked onto the beginning. A UDH can be used for various purposes and its contents and size varies"

In some networks, brands are also able to sponsor messages that are sent P2P (person-to-person). A typical MMS message based on the GSM encoding can have up to 1500 characters, whereas one based on Unicode can have up to 500 characters. Messages that are longer than the limit are truncated and not concatenated like an SMS. Good examples of mobile-originated MMS marketing campaigns are Motorola's ongoing campaigns at House of Blues venues, where the brand allows the consumer to"
"electronic communication through mobile phones and the Internet during the 1990s allowed for a marked rise in colloquial abbreviation. This was due largely to increasing popularity of textual communication services such as instant- and text messaging. SMS, for instance, supports message lengths of 160 characters at most (using the GSM 03.38 character set). This brevity gave rise to an informal abbreviation scheme sometimes called Textese, with which 10% or more of the words in a typical SMS message are abbreviated. More recently Twitter, a popular social networking service, began driving abbreviation use with 140 character message limits. In modern English,"

Owing to certain representations by service providers and consumers to increase the limit of 100 SMSes, TRAI had later decided to increase the limit of 100 SMSes per day per sim to 200 SMSes per day per Sim. In July 2012, the Delhi High Court removed the ban on the SMS limit of 200 per day per sim, as it felt that the restriction infringed the"

The Guinness world record text message consists of 160 characters in 25 words and was at that time typed in 25.94 seconds, which corresponds to a speed of nearly 58 words per minute, or 370 characters per minute."
"(UDH) containing segmentation information. Since UDH is part of the payload, the number of available characters per segment is lower: 153 for 7-bit encoding, 134 for 8-bit encoding and 67 for 16-bit encoding. The receiving handset is then responsible for reassembling the message and presenting it to the user as one long message. While the standard theoretically permits up to 255 segments, 10 segments is the practical maximum with some carriers, and long messages are often billed as equivalent to multiple SMS messages. Some providers have offered length-oriented pricing schemes for messages, although that type of pricing structure is rapidly"

At first, the situation was the same as with computers; neither mobile phones nor mobile network operators supported Cyrillic. Although mobile phone technology now supports Unicode including all variants of Cyrillic alphabets, a single SMS in Unicode is limited to 70 characters, whereas a Latinate SMS can have up to 160 characters. If a message exceeds the character limit, it is split into multiple parts. That makes messages written in Cyrillic more expensive. Sometimes ⟨y⟩, ⟨yu⟩,"

In another case, while the standard requires that the maximum size of a Nokia Mail address is 32 characters, some Nokia phones did not verify this standard, so if a user enters an email address over 32 characters, that leads to complete dysfunction of the e-mail handler and puts it out of commission. This attack is called ""curse of silence"".
