Instant Messenger App

Thanks everyone. She will use the WiFi.

The tip about her using WiFi somewhere is the key. Your iPhones came already with both an instant messenger program called "Messages," and a video conference program called "FaceTime." They both work great, no need to download anything. And regardless of carrier, using Wifi solves the problem.

(Before anybody whines about my assumption that they both had iPhones, I must point out that the OP didn't say what phones were involved, so all I can do is assume -- either that they have Apple phones, or that they don't. I made my choice.)

Depends on how cheap the company is. My DW works for a union hall and has a company phone and iPad both with great data plans.

I will be surprised if the 'company phone' even has data.

connect the limited phone to wifi at McD's, SB's, home network, etc. Use your choice of chat program - Google Hagnouts, Microsoft Skype, Snapchat, etc.

Chats will be transmitted over Wifi and will not cost data.

Two tin cans and a long string. No voice or data charges.

Duplicats deleted. sorry

There are lots of chat clients that will use data instead of text messages. When the device is connected to a Wifi network, the data should not be logged/metered to the carrier's data network.. WhatsApp, Google Chat/Hangouts, Facebook messenger, etc.

Not in those specific words. If this was company business why would the OP be asking?

OP, if you're trying to 'not affect' the company plan, how do you plan on hiding data usage? I don't get it.

The OP didn't say anything about personal usage. Maybe the OP is trying to save money for the friend's company? :W
