Just a thought as I play on a desktop.
Are you actually connecting straight to verizon, or are you using a home wifi router at home to connect, or using hotspots. If that answer is yes you might try rebooting your router. Also you might reconnect to internet or wifi on your device.
Also, is it only this game your are having problems with, if that answer is no, see above.
I know at times I might have to reboot either my cable modem or router, or both due to slowness, on either download or upload side.
But then again, I don't use the wifi of my router for the computers, hard wired, wifi is only for my wife's kindle. And maybe for future smart phones. Don't need them now, we wanted cell phones for phones. Us old farts are like that.
