Which message type to use
How Karnataka senders typically categorise their messages:
| Message | Category & suffix | Channel |
|---|
| Sign-in OTP for a Bengaluru fintech app | Transactional -T | SMS via HTTPS API; WhatsApp OTP fallback |
| UPI debit alert from a co-operative bank | Transactional -T | SMS |
| Hostel allotment for an admitted student | Service -S | SMS; WhatsApp for documents |
| Coffee subscription order shipped | Service -S | SMS; RCS with tracking button |
| Rajyotsava sale from a Mysuru silk store | Promotional -P | SMS in Kannada, 9 AM-9 PM |
| Patient discharge summary ready | Service -S | SMS with whitelisted link |
Keep offers out of -T and -S templates; one promotional line turns the whole message into -P. Compare categories on service explicit vs implicit SMS.

Kannada SMS for customers in Karnataka
Kannada is the official language of Karnataka, and customers outside the tech workforce often prefer it for bank alerts, school notices and offers. SMSGatewayHub sends Kannada Unicode SMS on all routes at no extra language fee, with 70 characters per part and an English sender ID.
Coastal districts also use Tulu and Konkani, which are commonly written in Kannada script, so the same Unicode setup works. For seasonal campaigns, see our Ugadi campaign ideas.
