MSG91 Opiniones 6

They pushed me to recharge a minimum of ₹5,000, promising they would credit double SMS credits for the first-time recharge. But even after waiting 3 days, they credited only 1,000 credits, which was completely different from what was promised.

At first, my API was manually approved. I used the API only for signup phone verification, and my usage was extremely limited—just a few test messages and only two real user signups.

After about one month, their team started calling me, sending SMS, and emailing me, claiming that all my SMS credits were finished and pressuring me to recharge again—despite the fact that I had barely used the API. When I asked what happened, they told me the credits were used from a Philippines IP/location. On most other SMS platforms, suspicious activity like this is prevented (for example, if too many SMS/OTP requests happen in a short time, the system blocks the IP or triggers security protection). With MSG91, there seemed to be no prevention, and my credits were drained without proper safeguards. As a customer, this made me feel completely unprotected—and honestly, it looks like my credits were taken unfairly.

Instead of properly resolving the issue, I kept getting repeated follow-ups asking me to recharge again. This feels misleading, unethical, and unprofessional.

I am totally disappointed and strongly advise others to be very cautious before using MSG91.

MSG91 can be a decent choice if you need a flexible, feature-rich messaging gateway - especially for OTPs, notifications, and small-to-medium-scale SMS needs. But it's not "perfect": delivery reliability and consistency might vary, and for critical use (e.g. large campaigns, time-sensitive messages), you should test carefully and weigh alternatives.

One thing I especially like is how reliable their message delivery tends to be. For the most part, messages go out quickly, and OTP or alert-type messages arrive almost instantly.

Easy to implement API, Supportive Account manager

Am using MSG91 SMS service for the last 5months but recently I have never seen this kind of worst service and support.

They provided a kind of SDK model so they should update proper documentation and proper updates of each change & should be sending updates to the client also. But They simply made changes and without review they just published.

I faced a lot of issues, the SMS is not working but they return SMS sent successfully but that is not delivered, SMS credit was debited even they log this kind of issue on their side,

I lost many clients due to the MSG91 mistake (worst SMS api), but they simply replied will check and update. Worst service and support.................
