Can you suggest an alternative to Voice? I need SMS and voice, and prefer data being optional (Voice can forward to a dumbphone, or even a landline). Happy to pay, just haven't found an obvious direct competitor.
Perhaps I'm missing your actual requirements (based on what's been suggested below), but I've been using voip.ms for years now. They support voice and SMS, and even my bank's SMS "2FA" works with them now. They don't support MMS, however (though you may have meant that when you said SMS).
SMS is available as a FLOSS app (I use the F-Droid voip.ms app), or through another portal - able to be sent/received through email, another number, or a web interface.
I honestly have only good things to say about them (despite being a consumer of their seemingly B2B product). As a disclaimer, I don't work for them, have no affiliation with them, and made a point of not using any kind of referral link.
I like the Unlisted app https://www.unlistedapp.com I got it a few years ago and haven't had any problems. I think it might be iOS only. There are plenty of other burner phone number apps which work on both Android and iOS.
Thanks for using and recommending Unlisted! We added an Android version last year and both apps are under active development. I'm happy to answer any questions (or receive feedback about what we could do better) - erik@unlistedapp.com
