As a result of the confinement, the need to communicate with our friends, family and co-workers using alternative methods to traditional calls has increased, and we have started using apps to call for free that do not generate additional costs on our bill.
From ANOVO we have wanted to compile the apps to call for
free most used by our technical team, which have the advantage of being
available for both Android and Apple iOS smartphones.
But before starting with this list remember that if you are
not using a Wi-Fi network at the time of using the apps that we mention below,
they will consume Megas of your data rate, so we recommend that you take a look
at our post about which video calling app consumes the least data?
Let's start with our list of the 7 apps to call for free
that we recommend:
1 - Google Duo
•This app has been developed by Google and claims to be
optimized for low-bandwidth connections.
•It allows you to switch between data and Wi-Fi signal
automatically without dropping the call.
•It can be used in smartphones, tablets, computer and, in
addition, in Google Home smart speakers, which is a great addition.
•It can be used as a video call app or as a voice call app.
•Use your phone's address book and specify that the users
you call are registered in Duo.
•It can work using a WiFi connection or our operator's data
connection.
•Allows up to 12 users to connect to the same call.
•It has a "Knock Knock" function, so before
picking up the call you can see a small live preview of the person calling you
to see who it is.
•It has an “answering machine” function, so if the person
you are calling does not answer the call, you can leave them a video message.
•From Google they ensure that the messages have end-to-end
encryption to increase the privacy and security of communications.
