Changing from individual plan to Family Plan
My daughter in Texas (with unlocked iPhone4) is currently on an individual plan w/ texting and data. She is due an upgrade soon.
Me, my wife and other child will move back to the USA this summer.
My wife and I already have iPhone5's, unlocked.
My other child does not now have a mobile phone and will need to get an iPhone as part of the new Family Plan.
So, we'll have 4 persons, all on iPhones and all living in the Houston, Texas area.
My Question . . . what's the best way for us to progress to a Family Plan, buy one new iPhone and upgrade the iPhone4. What are approximate costs for this?
BTW, we use mostly iMessage or WeChat for our messaging, not a huge amount of data.
