Too Buggy to bother

They should not release something that can’t do the fundamentals!

Everything is buggy - even calls don’t work - it hangs up after 2mins all the time. Can’t past numbers into the dial screen. App freezes and resets. Deleting and downloading fresh didn’t solve anything.

Bane of my life

I’m a new business owner and use BOnline for VOIP calling. It’s been a disaster and I would in NO way recommend it.

Really Bad nothing works properly

Really Bad nothing works properly, most of the the time calls are not available, when is finally available calls keeping dropping and bad quality to hear, most of the time if someone call me the app doesn't ring at all, so overall we are losing customers as a business using this service, The technical department needs to wake ups and start to take a serious action to get this issues sorted out ASAP.
