SCH-11 Throttled

[alakadabra]

I have a LC-11 flashed to 3g unlimited, via ebay seller. I've had this unit for about 2 months now and have gotten an awesome amount of use out of it. Steam, torrents, browsing, everything, its my home network. It is essentially my only option as I live in the country, and internet costs about 120 a month for a DSL line. I noticed that my data speed has went from 3mbps, to 2mbps, and now to about .15mbps. I've used a VPN to help prevent verizon seeing my traffic.

I was wondering if it is posssible to enable 4g on the device with unlimited data as the ping time is significantly lower. Also is there any options for unlimited 4g through sprint or att.

Much thanks
