Reducing stars. Sudden increase in fee for no reason. Introduce portability for US number, then will think once again to give you my business. Until then adieu. ##### My review won't be long. In a few words, OnOff is a reliable and cost effective solution to have two or more numbers on the same device. Call transition from app to cellular network is flawless and seamless. Since it uses cellular minutes, its quality is as good as a call made using device sim card. Nothing is free in the world and $1.99 per US number is a steal deal compared to other similar products which charges $9.99 per number. Just one request to OnOff team, please allow us to port in our US number. And keep developing.

I've paid for "TWO" numbers on this site. And every time I try to send a message. Or make a call. It goes to the "We just need a few more pies of information screen. With the "CONTINUE" bar across the bottom. And freezes up there. So for a service that will take your money in 3 seconds! You'd think it shouldn't take ?? minutes to make a call. Or send text!!!! If there was a "0" stars. I would have given it that!!!!!! So purchase at your own risk!!!!!!! TextNow is ""FREE" and runs a better app.

Most of the time it just works fine. If your signal is a bit marginal you may well find that calls fail to connect properly, which is annoying. It's easy to call back a customer but that doesn't look quite as professional as we would like. There is also a bit of a weird pause when answering calls which makes the start of the call awkward. It works for us (friendly local business) but is lacking the polish that some might be looking for.

Very useful application, but the quality is not there. I bought a Belgian number and the calls to/from Belgium were almost every time having low voice quality. The voice mail was sometimes working, sometimes not, as well I had some dropped calls issues. The app would be great if you could improve the routing.

Perfect for me. For 10 euros per month, I get unlimited calls and SMS with voicemail, to/from numbers in the country with which I need to communicate. This takes into account that I already have an unlimited local call plan, as the app calls a local number. App is quite well done, it integrates well with Android contacts although it has some minor bugs e.g. contact list sorting and synchronisation with Google contacts after modification. Voice quality is often good however some hear a very bad echo.

I have this app for a second professional number, the call or message does not go through and most of the time I have missing calls or message appearing when I open manually the app, I sent report and logs and each time they ask me to do the same stuff to check if it is working, wait for an update or just do nothing. If you require a trust of working from this app, avoid it

Absolutely fantastic app so clever and so easy to use... I love it! Well done. ... until now! ... this past month my onoff app won't work and keeps saying it is sending a verification request to my email ... but nothing arrives. I cannot access the app at all .... useless! ... and i have paid for full year on 2 numbers!
