I love it, and I use it all the time
KeepCalling is an affordable and reliable calling app that I use all the time when calling a friend who doesn't have Interne and so I can't use free calling apps. I gave it 4 stars because sometimes it keeps breaking, even often, but most of the time the call is crystal clean and lasts as long as we want. The main thing is that it's very affordable compared to other companies. Thanks so much!
