I was looking at changing to the start unlimited plan. It would save me $5 per line. I have go unlimited now. The only difference I can see is the start unlimited plan doesn't have mobile hotspot. But I was reading the fine print and it said if I have a phone I got with a discount I would be charged $20 extra dollars. Is that right ? I messaged Verizon and they said that was mainly for business accounts Does anyone know about this I don't won't to switch and then get hit with a $20 per line charge
