WhatsCall is an internet calling app and it also provide the facility to make calls to a number which is not connected to internet by using the available credits. The app is useful only for the first few days and soon you are ran out of credits. The calling experience is not at all good, your voice echoed and sometime the voice comes breaking from the other end. Overall I haven’t had a good experience with this app. It may have a million downloads in the playstore but that doesn’t mean that everyone is using the app happily. Some apps are downloaded to be uninstalled and this app is one among them. Do not waste your time, make calls from your service provider.
