Frequently Asked Questions (FAQ's)
An SMS Gateway allows businesses to send and receive text messages to and from mobile devices through a web platform or API. It acts as a bridge between the internet and mobile networks, enabling efficient communication.
Currently, our SMS Gateway supports sending messages only within Sri Lanka. However, we are actively working on adding international support to our gateway.
A Sender ID is the name or number that appears as the sender on the recipient’s phone when they receive your SMS. It helps identify your business or organization and enhances your brand’s recognition. Sender IDs are customizable but are limited to 11 characters.
The Sender ID is limited to 11 characters. This allows you to use your business name or an identifier within the character limit.
SMS length is typically calculated based on the number of characters in your message. For English messages:
1 SMS = 160 characters (standard)
If your message exceeds 160 characters, it will be split into multiple messages and sent as concatenated SMS.
Important Note: This character count applies primarily to English (GSM-7 character set).
For Unicode messages like Sinhala or Tamil, the character count differs because many Unicode characters (especially in Sinhala and Tamil) are combinations of multiple characters. Therefore, the calculation is done by character count, not by the number of letters or words. This means Unicode messages may reach the character limit faster than English messages.
