FAQ: MSG91 vs OnlineSMSService
Is OnlineSMSService cheaper than MSG91?
On published prices (October 2026), it depends on volume. OnlineSMSService charges ₹0.20 per SMS on Starter (up to 10,000 SMS/month) and ₹0.15 per SMS on Business (up to 1,00,000 SMS/month), the same for OTP, transactional and promotional SMS. MSG91 lists ₹0.16–₹0.25 per SMS and ₹0.18–₹0.25 per OTP, depending on pack size. At the Business tier, OnlineSMSService is below the lowest published MSG91 rate; at Starter volumes, prices are similar. MSG91 offers enterprise rates on request, so very high-volume senders should compare quotes.
Does MSG91 charge for DLT registration help?
MSG91 offers optional Premium DLT Support for ₹1,500 + GST, on top of the operator's one-time entity fee (about ₹5,000 + GST). OnlineSMSService includes DLT help at no extra charge. The operator fee applies with any provider.
How long does migration from MSG91 usually take?
For standard API workflows, a few hours to a few days, depending on how many templates you have, your callback logic and how much you test. Your DLT entity, headers and templates stay valid; you only link them to the new gateway.
Can I run MSG91 and OnlineSMSService in parallel?
Yes. Running both in parallel is the safest approach before a full cutover, and it lets you compare real delivery and latency on your own traffic.
What should I test before moving from MSG91?
Test template mapping, delivery-report callbacks, OTP latency at the 95th percentile, and how quickly support responds during your peak hours.
