Ask HN: How do you handle SMS and MMS?

Twilio is famously good at SMS/MMS

(disclosure: I work there)

Checkout RingCentral's offering (API's) for both SMS and MMS. They also have a web app that you can use without needing to write code to send SMS https://developers.ringcentral.com/api-products/sms

Does anybody know a programmatic VOIP provider that will appear as a standard mobile number? I've got a voip.ms number that cannot text with some other providers (like xfinity phone service), and website snake oil auth doesn't like it either. I've got another number with Google Voice that hasn't had these problems (I think because it looks just like a Project Fi number), but the lack of software choice sucks. I'd love to move away from Google, even if it means paying a bit, but the number has got to work as a general number.

I've got a plan to set up a fixed cell modem with a cheap SIM for snakeoil auth, etc, but that won't help for keeping a long term well-known number.

You'll need some service provider that will route your messages for you. Twilio is the probably the biggest, but my recommendation would be Telnyx.

voip.ms has worked well for my needs. As BruiseLee stated, Twilio is probably the largest and most integrated.

Some folks I know use this to help test MMS on the Pinephone.

I imagine it'll do what you want.

Been using twilio for over 4 years. 300-500 sms per day. Never a single issue, I don't recal having to adjust code in a few years. Couldn't be happier.

I am using Inteliquent for my start up. I believe they are behind Twilio, telnyx and Messagebird.

Twilio or MessageBird are worth a look at.
