Verizon to T-Mobile

I live in southern california and am seriously considering switching my 3 lines of service over to T-Mobile. I am hoping some of you can help me with a question I have. Ive been playing around building plans and Ive noticed that only the unlimited plan mentions the ability of using hotspot, which has a 5GB limit. Now I was thinking of going with the 3GB plan for my line, would I be able to hotspot? Or do I have to have the unlimited plan? Also if I cant with the 3GB plan, how stiff are they with enforcing the hotspot data? My Verizon plans have always included it and when I had Sprint and ATT I could just root or jailbreak and they didn't notice or care.

Thanks in advance for your help on this. Also if you have made the switch how are you liking it? Im looking forward to the phone selection and the savings!
