Hi Guys - I apologize if this has been discussed over and over. I did a forum search and yielded many older threads from when the Iphone 6 was first launched. I have an unlimited line with an iphone 5 as part of a family plan. My husband got the new iPhone 6 along with a separate individual 2 year contract when it first came out. Now we are looking to do a phone swap. Will I lose my unlimited data plan? It is hard to keep straight the different scenarios. Any advice would be much appreciated!
