My wife says i am a tech nerd, probably guilty as charged.
I feel the need to point out that you CANNOT text on wifi.
If, you have an iphone, you can imessage, or facebook message or whatever, but NOT a text message. Not everyone uses apple, so if you or anyone you wish to communicate with is on android, that won’t work.
One easy way to tell is to look at the color of the message, if it’s green, it’s a text, if it’s blue it’s an imessage.
Our burglar alarm for instance, sends text messages for any event, you won’t get those on wifi.
