Not Very Good At All! Incredibly temperamental and very frustrating! I installed the App, and it's been nothing short of useless! I've had to uninstall, reinstall, and now it won't accept my mobile number, club card number, nothing!! I've reported thus issue 3 times, sent emails, sent screen shots, last time at 10.33am this morning, and I'm still stuck waiting and hoping for it to be sorted, so no.. I'm one very unhappy customer! 😒

Have been using this as alternative to Lyca. It's been pretty good as I don't need to have dual SIM nor a secondary phone to call outside the UK. The is one frustrating problem though. The audio quality seems to drop drastically on international calls for some reason, even when connected to a strong WiFi signal. I need to literally shout down the phone to be heard. Any ideas why this is the case as this does not happen with any other VoIP services I've used.

Terrible! I've tried to top up with my credit card several times. The app is so buggy. It had trouble saving my initial details like name and club card details. Then after I inputted that several times, I could finally add credit card payment details. Then after passing that frustrating hurdle, at payment details it errored another 4 times. So I've still not been able to top up! I give up!
