It's a lot more complex than that actually. With Signalwire for example you can rent Canadian (and US) numbers at 0.2/m that work well with surprisingly many services, but not all. In a similar fashion you always find the right company to use/abuse any service that asks for a number. You won't get around the internet with a single cheap VOIP number tho. Plus there are providers with more or less perfect Sims but they are expensive. There are also services that are specialized on providing the right number for a one time fee. This usually works well, but more often than not destroys future account security (they all will give numbers out again, not relevant what they claim) I could literally write a book about my life without a 'real' phone number.
