I think TextNow offers a better solution and I've been using it to do this for quite some time and it doesn't require any kind of forwarding. I can send/receive calls and messages directly from within its app and recycle numbers at any time - all for free (ad supported). Calls are of great quality too and it even includes voicemail. If I really like a number and want to lock it (to also receive 2FA codes), it's a yearly $7 fee. Works with area codes in US and Canada.

I think there are other options like Fongo and probably a dozen other similar services that already have been doing this for some time. Not really seeing the value proposition of going with the Mozilla option here. Am I missing something?

I silently miss so many incoming calls with TextNow and from reviews it seems I'm not the only one, but I don't really know another option for a Canadian number.

I have heard similar things from friends that use it on iOS but on Android, I haven't missed any call I was expecting. Even when I've lost connection to data (e.g., in an elevator or something) and a call was made, at least I see the missed call notification after my data was restored. Fongo is another option for a Canadian option.
