Very disappointed that the App will no longer work. It has been useful to use when abroad to keep in touch with elderly relatives who don't have smart phones or internet and for whom phrases like Dataplan, WhatsApp, Skype and Viber are totally incomprehensible. Also useful if there is a wifi signal, but no phone signal.
Smartcall was a superb app for me, as i live in a area that as next to no mobile signal.Seems that Virgin are hell bent on saving money at our expense. This may turn out to be a expensive exercise in the long run.
