If you don't absolutely need this to originate from a mobile subscription with your name on it, you can for far less money get a DID ("direct inwards dial"; the term colloquially means a virtual mobile number) with any of the numerous VoIP providers out there. Most of them not only provide in- and outbound calls on those DIDs, but also ditto for SMSes. The interface for voice calls is almost exclusively SIP, and for SMSes it's usually an HTTP-based API.

If you go this route, make sure you absolutely know how to, and that you absolutely lock this down. SIP toll fraud is still a problem and if it happens to you, it can get destructively expensive.

Common sense obviously applies. With a cell phone, don't call back to unknown numbers ringing once or twice ("wangiri"). With a SIP trunk, don't allow remote anonymous access.

Yeah I suppose it's really easy to call this common-sense, it probably should be common-sense.

Yet at the same time, if it were common-sense in practice, I probably wouldn't have a job.

These services are great, except for the sites with mandatory sms 2fa that refuse to send to voip phone numbers (I'm looking at you, Apple).
