First, for some context (I'm adding this as representatives always look at me like I'm crazy when I say, "No, I don't want the ONE plan, and yes, I know it's unlimited"):
I'm debating going from the Simple Choice North America 10 GB plan (with data stash) to the new ONE plan (the basic one). With all the promotions over the years, going to the ONE plan would cost more, so I left it alone. My current plan is $120 for 6 lines, unlimited everything, with 10 GB/line LTE, taxes excluded..., and a tablet at $25 with 6 GB -- everything with taxes is $177 while the ONE plan would be $200. None of my current lines ever go above 10 GB of data usage (thanks to BingOn!), so staying with my current plan is ideal as I have fast tethering with that data stash bump when I need it, after that I would just hit the current ONE's restrictions.
So, the game changer is the new military discounts. My plan could go from the $177 to about $140, and the Netflix rebate adds another $10 in savings (even if it doesn't last) for a total of about $50/month. The only thing I lose is fast tethering for those times I need it. I'd have to use my LTE devices for the big data items instead of not caring as it didn't really matter before. If I needed to download something big, such as a large ISO, I could download it to my LTE device first, then transfer it locally to my computer, so not a big deal there. But, I do use tethering for work sometimes and this is the largest variable.
Now, the question is, how fast is the 3G tethering? I've been looking and looking, but can't find anything that actually says, it is xxx kbps. I've seen non TMobile sites claim it's at 512 kbps and others that say 128 kbps. I've seen on T-Mobile's site that wearables are maxed at 512 kbps and tethering in foreign countries is maxed at 128 kbps, but tethering is just "3G". I can determine if the speeds will be an issue using rate limiters on my firewall, so I just need to know T-Mobile's theoretical 3G speed. Is it 512 kbps or 128 kbps or something else? Outside of tower congestion and going over 50 GB and being throttled, what are the actual throughput speeds (taken in the best of conditions of course, such as near a tower and not where there isn't any coverage). Can someone provide a link on the T-Mobile site that says the speeds in numerical format? And can someone provide actual speed test results while tethering while using the ONE plan?
And, just to put it out there, I'm not looking for ways to mask tethering (that's easy) - if I was going to go that route, I wouldn't be asking my question.
Thanks in advance!
