Hi, I want to block text messages on ios 9.3 from someone who sends group messages to my ATT iphone 6s+. Since they have Android or dumb phone I am getting charged due to overages on my text plan. If I set "block this caller" in my contacts are the texts being rejected and not count towards my total text messages? Or is iphone just deleting incoming text messages but ATT is adding 1 text message to my total count for each time this person sends? i have a 200 text message plan and only reserve it for emergencies for green bubble friends. Most of the people I know use imessage. Thanks.
