So, now that you have bought a new cell phone, you must be wondering what talk plan to choose? With all companies pitching in to woo you, it is important to choose only once you have identified your needs and pocket.
Your calling plan will decide the minimum amount you will have to pay to the service provider in a month. It's like an agreement that you make to use your phone for certain amount of time each month. Keep in mind the options available to you before choosing a talk plan.

In India, we use the digital network specified as GSM 900 (Global Systems for Mobile communications). The digital standard, including CDMA, TDMA and GSM platforms, allows for more callers to at the same time, occupy space on each of a service provider's cells, making it the superior choice for highly populated or metropolitan areas. Disadvantages to digital systems are their lack of unified technology and a small, metropolitan-focused calling area.

Ask yourself. Do you want a cellular phone for emergency use? Will you be using your phone/service around town? Travel a lot? Planning a coast-to-coast?
Whether local, National or International you'll want to choose a calling plan that encompasses the physical boundaries of your calling needs. While using your cell phone on an occasional trip away from home may add extra roaming or long-distance fees to your bill. National plans, are more expensive than local plans,but will give you the freedom to call regardless of your geographical location.

Caller ID, three-way calling, voice-mail, numeric paging, call forwarding and Internet access are just some of the great options offered to calling plan subscribers.

Subscriber Identity Module, or a SIM card is the key to European and Asian mobile communications, the digital equivalent of an ID card. All the information about the service you subscribe to, your plan details, your phone number, etc. are stored in this thin, credit card-like unit. It's placed in the handset to activate the phone and your service.
A SIM card contains integrated chips that extend its intelligence and capabilities by leaps and bounds. Apart from being able to store your entire phone directory, this smart card provides access to a whole range of applications such as short message service, mobile banking, and even the mobile Internet. Your phone becomes personalised and user-friendly.
The big advantage from a user's point of view is the great flexibility of SIM cards. When traveling, you don't need to carry your phone, just take the card. Rent a phone from the airport once you arrive, slip the card in the phone and you are again connected to the world, with the same phone number.
Each card has an authentication code, a password or a PIN, specific to your service provider, which ensures that only you are using the card. GSM's encryption technology is fairly advanced and is considered to be one of the most secure technologies in mobile communications.
PIN / PUK
The SIM Card has a security feature called the PIN / PUK- a four-digit number. You can change this number to any four-digit number of your choice using the handset. Once set, three wrong attempts of entering the PIN / PUK can get the SIM card blocked temporarily. It now requires the Master PIN / PUK number to unblock the SIM. Generally ten wrong attempts to enter the PUK number can get the SIM card blocked permanently and it will require a SIM exchange.

The SIM Card can be permanently damaged, if
