A few years ago it was common get truly unlimited data plans when we signed up for new smartphone. That meant you could use all the data you wanted and there was no talk of charging you more or throttling your speeds. As smartphone users that have unlimited data plans originally began to upgrade devices, many were grandfathered in to still get their unlimited data.
Verizon is one of the carriers that used this grandfathered plan and the company is now set to kill that clause 4 the $30 monthly 3G users. As those users of unlimited 3G data migrate to 4G LTE plans they will be forced to move off the $30 unlimited plan onto a data shared plan.
Verizon is obviously afraid that by allowing these grandfathered users to continue unlimited data on 4G plans, the consumers may actually start to use the speedy data. This is bad news for grandfathered unlimited users.
