Bulk SMS is the sending of one message, or a personalised version of it, to a large list of mobile numbers at once. Businesses in India use bulk SMS for offers, order and account alerts, reminders and OTPs, because SMS reaches every mobile phone on every network without internet.

A sender ID (also called a header) is the 6-character name customers see instead of a phone number, such as SHOPIN. In India it must be registered on DLT, and the last letter shown (-P, -S, -T or -G) tells customers if the message is promotional, service, transactional or government.

One SMS holds 160 characters in English (GSM-7) or 70 characters in Hindi and other Unicode scripts. Longer messages are split into parts of 153 or 67 characters, and each part counts as one SMS credit. Use our free SMS character counter to check before sending.
