Gonna wait to offer judgement...and here it is:
Had a suweet old plan in which I had unlimited DATA for three smart phones, but I was buying data for two iPads.
The sales staff was able to get us moved over to a plan that included data for the two phones, add another iPhone and three iPads for the same cost as the original plan!!! And to be clear, I am saying we bought the third iPhone...bought three iPads...and added data for those 4 new devices AND keep data for the two existing iPads...ALL FOR THE SAME PRICE AS THE ORIGINAL PLAN! All of these devices collectively use less than 10 gigs monthly.
Customer service was excellent.
