If you are T-Mobile subscriber, or if you are planning to be a T-Mobile subscriber, you might want to hurry because come April 4th, new T-Mobile customers can expect to see a price hike in their Classic Unlimited plans and will have to pay an extra $5 for the 5GB and 10GB data plans. For those who sign up prior to the 4th of April, you guys will be paying the current prices and will continue paying those prices until you decide to opt out or cancel your subscription. We’re not sure how well new customers might react to the price hikes, especially if compared to their friends using a similar plan at a lower price, but we guess T-Mobile is doing everything they can to keep themselves up and running even after shutting down 7 of their call centers in a bid to save money.
