Hi! I'm thinking about getting the T-Mobile 4G Mobile Hotspot plan for $20/month, but I don't want to buy their hotspot devices. Instead, I was wondering if I would be able to use my Galaxy Nexus as a wireless hotspot and use wi-fi tethering. I really don't want to spent over a $100 dollars on those devices. Is this possible? If so, what speeds would I get on my Galaxy Nexus? Would there be any additional monthly charge? I am currently on T-Mobile's family talk/text plan with no data. Thanks a lot!
