Binge on not working

I contacted Tech support and learned something "new" for those of us with "unlimited LTE plans" binge on helps  somewhat. Apparently when binge on was explained,and as you stated data consumed via a binge on provider doesn't count towards high-speed data allotment this is helpful for plans with fixed 4g LTE data buckets, however for those of us who have unlimited 4G LTE allotments, "all data" is counted towards the 50gb threshold, which is fine, now that I have two phones and based on the prior information I switched my tablet off a legacy plan SC match 5GB for $20 to 6GB $35 with data stash., I was a little upset at 1st because I cut "the cord" and I switched my tablet plan when there was no need too, I just use my second phones' hotspot full time now. I do have a question? why is 3G no longer usable, when 3G was the standard, you could surf and stream with relative ease, now it preforms like dial up sloooooow. I do get it, TMO is a business an needs to turn a profit and having 3g upgrades to LTE upgrades is a source for revenue we get it an despite some TMO does offer the most bang for our buck, even with it's newer offerings "TMO ONE", I can't see myself moving to TMO ONE anytime soon.
