Trying to decide whether it makes sense to switch to the Edge plan. Currently we have 3 iphones (2-4s and 1-5). I am due for an update now and will get the iphone 6 tomorrow. Wife's upgrade date is not until 9/14/15 and daughter's not until 6/28/16. My son will likely be getting a phone next summer, say 7/1/15. My understanding is that you cannot get onto the Edge plan until you purchase a new phone so based on our current update dates we would not have all 4 on the Edge plan until 2016. Is this right? It seems like the Edge plan makes the most sense when you have 4 people on the plan and your line access drops to $15/phone + 10 GB of data for $160. Is there anyway to get everyone onto this plan sooner?
