T-Mobile is best known for their competitive pricing and their superior customer service. T-Mobile offers superior value plans with no contracts required. While people do not like to sign contracts, there are advantages and disadvantages. The disadvantage is that subsidized phones are no longer offered. Customers with T-Mobile will have to either purchase their phone outright or make a down payment and make monthly installments for over 24 months. Customers who cancel their T-Mobile service will have to pay the outstanding balance on their phones before they can switch to another service provider.
