If you don't know what WhatsApp and Signal are they are two ways to send texts and phone calls and pictures and videos around the world for free to friends and relatives

However, WhatsApp is wonderful BUT they sell this information now they are bought by Facebook. So, my older daughter who is very tech savvy wanted our whole family to switch to Signal and most of us have now. So far at least Signal has not been bought by someone who will sell everyone's information around the world like Facebook does. So, even though WhatsApp works better than Signal does still if you want your information more safe and secure then Signal is a better choice for talking and texting with your friends and relatives worldwide for free.
