Burner is an app that gives you extra phone lines on your smartphone. Its core idea is in the name: create a line for a specific purpose — a classified ad, a short project, a first date — and "burn" it when you are done. According to its website, the app focuses on US and Canadian numbers and offers subscription-style plans billed through app stores.
That design is excellent for keeping short-term contacts at arm's length. It is less suited to account verification, for two reasons. First, lines are typically VoIP numbers, which some apps and banks refuse during sign-up. Second, the whole point is that the number goes away — which is the opposite of what you want for an account that may send you a recovery code later. Once a number is released, it can be recycled to someone else (see number recycling).
PhoneBorn offers two separate products for these two needs. A plan gives you a real mobile number that you keep for as long as you renew, with SMS and calls both ways. An OTP number is single-use: one service, one code, refunded automatically if nothing arrives.
