A few things. Make sure you have the proper data package on your plan (4G web / 5GB Premium ulimited data, 2GB unlimited data, 10GB premium unlimited data, etc.).
Then check and see if you have the $14.99 wifi Hotspot on your plan.
If not, call up T-Mobile USA or go into your myTmobile web account and add it there, and you should be in business.
I was under the impression that "Wi-Fi Hotspot" and "USB Tethering" were two different things. (Because they are!) Now they want more money? Please show me in the documentation where these are discussed? I would not have paid $300 for this Samsung Galaxy S Blaze if I had known that was the case. I'm just about ready to send it back and go with Verizon!! NICE FALSE ADVERTISING T-MOBILE!!
Smartphone Mobile Hotspot ReadyUse your device's web connection to connect laptops and other Wi-Fi enabled devices to the Internet.
I see nothing about USB Tethering listed as an extra charge on anything in this phones description?
