Why from 2nd SMS credit is counted for 306 characters instead of 320 characters?<\/strong><\/p>\n\n\n\n

To deliver as a Single Text Messag<\/strong>e while combining the multi-part SMS then few headers needs to be combined and takes up the extra 7 characters space from every 2nd message. The same applies with unicode message when you use non-GSM characters set but here it takes 3 characters space from every 2nd message.<\/p>\n\n\n\n

Standard SMS of 1 SMS credit is 160 characters long which includes spaces. Check out our Text Messages Chart<\/a><\/strong>.<\/p>\n\n\n\n

Multi-part SMS Message is defined when you use or send more than 160 characters SMS message. Though credits are counted in multiples, but the SMS Message<\/strong> will be delivered as one single message to the Recipient’s Mobile.<\/p>\n\n\n\n

While sending SMS, GSM 03.38 Character Set is used. GSM 03.38 character set characterizes GSM 7 bit alphabet with extension table and GSM 8 bit data encoding.<\/p>\n\n\n\n

When sending SMS using non-GSM 03.38 characters, the SMS gets terminated as UNICODE Message. Even if you have a single non-GSM character, the whole message gets converted as unicode message.<\/p>\n\n\n\n

For Example: When you use “Hello [Samir] ^_^<\/span>” then the total characters used are 21 with 7 bit encoding.<\/p>\n\n\n\n
