What are some reliable SMS providers for OTP and alerts besides Twilio?
Asked by

I'm looking to roll out OTP logins and some automated system alerts for a mid-sized organization. We've been using Twilio, but the costs are adding up, and their support hasn't been responsive when we've faced delivery issues. So, I'm curious about what other sysadmins are using for: - Fast OTP delivery (latency has been noticeable lately) - Solid uptime and reliability - Helpful reporting/logs for troubleshooting. I'd really appreciate any recommendations before we commit to a long-term solution.

We switched from Twilio for the same reasons—high costs and slow support. We started using Signalhouse.io, and it’s been a game changer! OTPs deliver almost instantly now, and their logs provide useful error codes, which helps a lot with troubleshooting.

If you're in the EU, give Retarus a shot; they have services in other regions as well.

Another option to consider is Telnyx. They've worked well for others.

When you mention OTP delivery, are you talking about shared logins? If so, you might want to look into TOTP seeds in your PAM solutions like Bitwarden for real-time access and better audit capabilities. Also, for system alerts, PagerDuty often comes highly recommended.

I've heard great things about Courier. It's a solid option that also lets you coordinate email and push notifications. They have a decent free tier if you want to try it out first.
