Keep your phone bill within the budget
Before selecting any talk plan try to estimate the requirement. If it is a family phone, try to take the economy plan so that you can manage to enjoy the maximum flexibility. Install a timer in the LCD of the handset, so while talking you can have a look on the time and accordingly finish up your conversation.
Do not keep the option of Internet on the same phone and always try to cancel or restrict the facilities like call forwarding, call diver facilities that simply add some extra amount to your monthly phone bill. Ask for the itemized bill so that you can have a look on the calling habits of you household members.
