I am using a Sprint post paid cell phone, its bills costs me a lot. Now willing to change the service and the plan too. I have decided to switch to any cheap per paid cell phone which have the cheapest call rates and free unlimited text messaging services. It will be the best if my plan also provides me some free data usage every month. I can spend up to $ 20 per month for the services on my cell phone. If you are aware of any such plan with any service provider then please do shear with me.
