sorry i have been away for a while, i have now had the service for a year and yes i have the lg x charge, i was able to pay just 3.oo for each phone so i purchased three, one for me, one for wife , and one for home/children when they are at dance/soccer/girl scouts. etc.
the only thing that i feel is lacking on my phone is the camera, it takes good pictures but it is definitely not a "high end" camera. does the job for me though.
the service is indeed piggy backed on Verizon, so that was not a big change for us as tracfone was also on Verizon. great calling, texting and data coverage.
as a side experience, i had the opportunity to travel to Germany, Austria, and Italy for a week, ( work sent me.... saying with early retirement i could never afford to go otherwise)
the service while in Europe is .10 cents a minute/ meg of data/ text. that can get really expensive fast. the coverage was great in all three country's! but as in a must-stash fashion i turned my phone on airplane mode and utilized the free WiFi calling/texting of my google voice, which work out better than expected, I found myself able to really enjoy myself in the moment because I was not worried about checking my phone all of the time! (this is another tip I would like to share with everyone! social media is such a burden! I canceled all of my social media accounts and am proud to say that my life and time have done nothing but increased!
I would recommend xfinty mobile to anyone.
another side note, i recommended xfinity to a guy at work, he jumped in and bout the Samsung galaxy... not sure of the model but he has problems with phone calls dropping. he told me that his wife with the same phone also has the same problem, so heads up it may be better not to use it on xfinity.
