What is SMS credit? How many letters can I write in a SMS?

SMS stands for Short Message Service and is also commonly referred to as a “text message”. SMS credit typically refers to the number of text messages you can send or receive using a SMS platform. 
 
The number of characters you can write in a standard SMS message is limited to 160 characters. With a SMS, you can send a message of up to 160 characters to another device or another mobile phone. This limit includes both the text and any spaces or punctuation marks. If your message exceeds this limit, it may be split into multiple messages, and you may be charged accordingly.
 
1 SMS Credit = 160 characters including spaces in English.
 
In newly added *Promotional Route, you can send a message with the length of 360 characters through a single message, but your SMS credits will deducted as per Letters used in the message.
 
The message length allowed for 1 credit message is 160 characters. If the text length exceeds 160 characters, then the message consumes 2 credits. The character length for 2 messages is 306.
