Not happy with your mobile phone service? Sprint (NYSE: S)is about to make it much easier and much cheaper to change your mind and your wireless carrier.

The Overland Park, Kansas-based wireless phone carrier Sprint is planning to begin a money-back guarantee offer for all its new customers who are opening lines of service. The new guarantee will reimburse any dissatisfied customers for nearly all charges they have paid or accumulate within the first 30 days of a new contract with the wireless carrier.

The Sprint Free Guarantee will start tomorrow for all customers that contract new lines of service with the company. If customers should change their minds during the first 30 day period, Sprint will accept their wireless devises and issue a refund without charging a stocking fee. They will also waive the early termination fee and customers will get a refund on any recurring monthly plan charges, activation fees, and all relevant taxes and surcharges from Sprint. Customers would only be responsible for paying any fees for use of their device not covered under their monthly plan, including services like downloaded content, international calls and any applicable taxes related to those services.

Most wireless carriers already forgive many charges or fees if a customer is dissatisfied with service within the first month. However, some wireless companies will still charge rates for phone use during that time as well as charges for activation and restocking fees of the devices returned.

Sprint is hoping to attract more customers with the Sprint Free Guarantee program and the company’s consumer services President Bob Johnson stated that the plan reduces ‘the anxiety subscribers may have about changing wireless providers’. He goes on to say ‘This guarantee is a strong statement about our confidence in the improvements we have made in our network, customer experience, rate plans and handset lineup’

Sprint has tried many strategies to increase its amount of new service subscribers and reduce the loss of customers to competitors like AT&T Inc (NYSE: T) and Verizon Wireless (NYSE: VZ). Television advertising for the new Sprint Free Guarantee program will begin running Thursday and will feature Sprint CEO Dan Hesse, said the company in a statement.
