Your carrier should not be charging you for inbound SMS, changing SMS enablement providers can usually be done in a few minutes.

I would encourage you to look at Teli, Telnyx & Signalwire, iirc they all support blocking texts from a particular number. Avoid Bandwidth.com unless you want to deal with a long sales funnel and chasing them for API keys they never provide.

Agreed!

Thank you, a quick glance seems to indicate they do not charge for inbound SMS on local numbers.

Teli has treated us well for years, they use some small cell provider in the midwest for SMS/MMS enablement. Signalwire is essentially Bandwidth.com without the sales funnel.

FWIW, I looked through the APIs and while I did see mechanisms for rejecting phone calls and faxes, I did not see a way to block specific numbers from sending you SMS. Not that it matters, free inbound more or less solves the problem. Thanks again.

Hrm, it looks like its a documented endpoint: https://apidocs.teleapi.net/api/my-phone-numbers/block-inbou...
