1 ★ Utter scam!!! No stars fro scammers. It offers only 1 choice of country and when you chose the number it counts down 5 minutes within which you can not do anything as there is no interface to carry on then after 5 min it says you were too slow to select your number and removes all options to get any number or from any other country too as it never even gives such choice available. Utter scam!!! Is this what should be allowed on google play? Does google have any control and check over google play
1 ★ I travel a lot so I've been using OnOff for years to receive texts when I change SIM cards when traveling. It's been working great for me. Support is friendly and responsive. Edit: Huge price increase.
3 ★ 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.
4 ★ 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.
3 ★ 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.
1 ★ Impossible to stop the subscribtion and they take more money. All the system is build to take money as much as possible.
1 ★ I will give 5 stars when my issue is ameliorated .I've been using this app for years with different cell phones and I've paid for year long contracts with phone numbers but I can use none of the ones I've purchased. Suddenly there's a button that says "validate" and gives loose instructions on how to which do not work no matter what I do. The last time I had an issue with you all you wanted me to send a copy of my.passpirt to your company in France, which I am not doing now as I did not do then.
4 ★ I've had this app about 3 yrs using a Galaxy Note 4, then 9 on Android.. sends texts and calls seem to work fine but can take a few frustrating seconds to answer..ince in a while one can't answer so I have to call them back so then using my credit which is just 30mins Voice, a month which can go very goes fast. Why not roll over the non used voice calls and texts? But overall it has worked well as my non important 2nd number.
2 ★ Dropping from 4 stars to 2 stars because the app just sits on loading signal and I have to open chrome and use the OnOff Web client in order to access my calls & texts. App worked fine up until about 3 months ago. Running Android 11 - HD1925. App just stays on startup screen with the circle spinning and never loads login portal.
5 ★ After using it for a while I had to port the number to another carrier, but I was charged anyway. I contacted the guys, they did a quick check and I got a refund immeditely. They're really professional, the app continues to be perfect even after you stop using it ;-)
1 ★ 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
5 ★ Please guys make this work all these cook features are so promising 😭 and please allow them for cad sim cards too, Also thanks for your response, being able to access to numbers in canada like that while calling through the samsung phone app, is almost the equivalent of having a dual sim card phone its genius. If this app runs properly I'm sure you guys would go through the roof
1 ★ on the app after payment it kept saying insufficient funds and refusing so i had to pay by credit card and then i see they also charged my playstore balance! on top of that the service does not work the only number i wanted to call says cannot be called by the app. and customer support just says payments are not they're problem and do deal with playstore directly...
1 ★ Terrible experience. Never works, no notifications ever even when activated. No communication about the billing. When you ask for a refund they don't do anything. 10€ for what they "offer" is a complete rip off. And they make their consumers feel stupid.
5 ★ The app is doing good but needs more improvement, it's always difficult to validate am expires number
