What it is
A temporary phone number is a real mobile number you rent for one job: receiving a verification code. On CoveSMS it stays reserved for you for 20 minutes, the code shows up in your dashboard, and then the number closes.
How long it lasts
Long enough for one code. If no SMS arrives in 20 minutes, the price goes back to your balance. It isn’t a number to keep for months; for that you need a SIM, an eSIM or a paid long-term number.
Which apps accept one
Most apps check whether a number is mobile or VoIP before sending a code. Temporary mobile numbers pass that check far more often than free VoIP numbers. No provider can promise every app accepts every number, which is why getting your balance back matters more than any promise.
What happens to the account afterwards
- You stay logged in on that device
- A new login or a password reset may ask for a code on the same number, which is gone by then
- So add your own email and an authenticator app as soon as you’re in
Good uses
- Trying an app before trusting it with your real number
- Keeping your number off marketplaces, dating and loyalty apps
- Separate accounts for work, side projects or testing
- Verifying while travelling without your home SIM
