However our tech department today did get a Verizon representative to admit that our corporate unlimited data plan actually does throttle users starting as early as 5 gigabytes. The decision of when to throttle is market dependent. Therefore in crappy little congested markets like mine where there is not a lot of good bandwidth to begin with, throttling can come as early as 5 gigabytes. However in bigger cities, throttling is not likely not to occur until higher data usage has been met. Verizon's corporate unlimited plan is unlimited where you get unlimited data, but after a certain point you can be throttled to unusably slow one x speed. Unlike T Mobile, Verizon does not admit readily that they do this and does not put this on their website. I have to give tmobile respect for being more upfront and honest in the first place about their very similar plans.
Everything from the original thread below is answered in the paragraph above.
So here's my conundrum. I recently had to Oden my s5 back to stock because something went wrong when enabling download booster. After re-installing stock with Oden, doing download booster (no issues the second time) and several other tweaks, including getting SHealth and XPosed to play friendly, removing all the other bloat via the script running around this forum and adding buttons to the notification panel, I have noticed my data is really slow (Data plan only, WiFi is fine).
I know it's not Verizon, as I have two Verizon phones (S5 and Razr M) and the Razr works fine - in fact, multiple speed tests show the Razr M getting speeds 500-1000x faster than my S5. My S5 clocks in at or below 0.1 Mb/S. I didn't discover the problem until leaving the house and realizing that I didn't have enough data to stream Songza or Milk or tunein once I wasn't on my home network.
The s5 shows the 4GLTE symbol and does have a data flowing... it's just like looking at Early Era Dial Up when next to my other device on the same network. The phone itself is speedy and shows no signs of issue. Like I said, I didn't know there was a problem until I finally left the house.
I had noticed that the download booster wasn't useful for me as the LTE speeds were always too slow so it just went with WiFi in my testing, so this tells me that the error occurred very shortly after flashing stock with Oden. The Oden image I used was: ALL_VZW_G900VVRU1ANCG_G900VVZW1ANCG_964333_REV00_u ser_low_ship_MULTI_CERT.tar.md5 I thought this to be the correct one for my phone.
Before the reflashing, my phone was speedy on the verizon network. In fact, I had used it to tether a few times as it was better for streaming the World Cup than Time Warner on ESPN3. FWIW, I am on an unlimited corporate data plan with the S5.
