A mobile contract is an agreement between a customer and a mobile service provider, such as Verizon or AT&T, that outlines the terms of service for using a mobile phone. Typically, these contracts last for one to two years and include a monthly fee for voice, text, and data services. Customers may also receive a discounted or subsidized phone as part of the contract. In addition to the monthly fees, mobile contracts often include terms regarding early termination, which can result in penalties if the customer cancels the service before the contract ends. Customers should carefully review the contract details to understand their obligations and any additional charges.
