I am using a post paid cell phone from AT&T network, being a post paid plan I do not get any idea about the calls in a month and have a heavy cell phone bill at the end of month, which gives an extra pressure on my pocket. So I have decided to switch on prepaid cell phone plan so that I can have control on my cell phone bills according to my budget. Please you do suggest any prepaid cell phone plan which have attractive offers as free text messaging, more number of free talking minutes and data usage at very cheap rates.
