With my employer discount I can get the $70/mo 4G unlimited everything T-Mo plan for ~$65 after taxes. OR I can go with one of the prepaid companies and pay $40-50/mo where they give you very limited 4G and is dropped down to 3G after a low data point is reached. I don't plan on heavy internet usage but it would be nice to have something that runs decently fast when I do use it. I've never really used phone internet before so I have no idea on the actual speed difference between 3G/4G. For network coverage purposes, I'm in San Diego. Is it worth the extra $ to go with T-Mo?
