I live in Canada, and I am figuring out a way to get a “registered” phone number from a cell company just for SMS verification texts. However, I am wanting to find out if there is a service that would do the same thing (and potentially cheaper: the lowest plan I found from a carrier is CAD$15/mo). I would be using it just for SMS verification texts (WhatsApp, Telegram, etc.).
Tello gives you a real (US though) number, E911 and all, for 5 USD a month. You get an eSIM you can activate from anywhere in the world via Wi-Fi Calling. Send and receive unlimited texts and get 100 minutes a month for the odd service that insists on verification calls rather than texts. I’ve had zero issues.
