hi, I had the original unlimited plan grandfathered until recently when at&t first announced the new unlimited plan I switched. I have three lines and would like to keep fast speeds so the unlimited choice is not an option for me. I also have 18% FAN discount so my monthly right now is about $165. My question is this: does it make sense to switch to the unlimited plus plan? It looks like if I do the math correctly it will be $170 / month for three lines with no discounts available. In short it looks like i would gain mobile hotspot for $5 extra a month. Does it makes sense to switch?
