A 15 yr old granddaughter on my Family Ties account consistently uses the bulk of our 15 GB monthly data allowance which threatens overages if I don't turn off her data usage and carefully monitor what the rest of us are using. I have reviewed her usage details and find that most of her transactions are IM text messages (nearly 3,000 for the past 3 week period). She does use "mobile data" some too, but at times when her phone should be connected to WIFI at her residence.
I am getting mixed feedback about the amount of data an IM vs regular text message uses.
Can anyone provide more information please?
Thanks
