tiredhhhhhh ,

Works well

Actually got a text from my new number, whereas on the others I didn’t get anything. Easy to use. Only issue is that it’s a fiver to use the number for a one off thing but it works well

Developer Response ,

Thank you !

When placing a call it actually generates a local number you need to call using your normal phone and SIM card, so not only do you have to pay Onoff but you also pay your phone provider for a call - it’s not VoIP and doesn’t use WiFi. If you’re abroad forget it as your phone provider will be charging you a lot for the local call.

Finally they seem to be purchasing (very obvious) fake reviews for this app - some very similar 5 star ratings from randomly generated usernames. Look, if you’re going to buy fake reviews at least try to make them seem legitimate.

The app has been working fine for me for the last few months. Recently my credits disappeared from my account but the issue was resolved through their customer service. I’ve tried all the other 2nd number apps however so far OnOff is the best in my opinion.
