A SIM card for the phone is like having a small computer in your computer. The SIM card stores a lot of data such as your messages, whether text or pictures, your phone number, reminders, files, value added services etc. What determine the phone number are actually the card and not the phone. In fact the mobile phone company keeps track of all your calls whether incoming or outgoing through your SIM card. They can identify the precise city and country that you have taken the phone to. In this way, the company charges you for the calls.
The SIM card is actually called a Subscriber Identity Module and is the size of a thumb impression. This tiny chip is a small microprocessor, but it packs in a lot of data and information. It?s inserted into the back of the cell phone that one is using and only then can the cell phone be activated. As soon as the cell phone is activated, it?s connected to the network of the cellular phone company. Thus one can start making and receiving calls.
Therefore when you switch over to another mobile company, you need to purchase another SIM card to make and receive calls. SIMS can have a memory of 16kb to 64kb as of today. Of course with convergence happening, SIM may have larger memories to take care of many operations.
There are two types of connections for SIM cards. One is a prepaid connection where you for a fixed calling value, let?s say $10, can get for example 100 minutes of talk time. The second option is that of post paid. After every billing cycle, the cellular company will charge you, dependent upon AA you can run a bill of $100 dependent upon the usage.

Navigating the Maze for Low Cost International Calls
Navigating the Maze for Low Cost International Calls
by: Chris Robertson
I know I'm not alone in feeling as though I'm in the Dark Ages when it comes to figuring out phone services and various calling plans. I'm truly not a Luddite, but with the plethora of phones, phone cards, calling cards, long distance phone service options, and local phone service options available, how is the average consumer supposed to make an informed decision? There are times when I find myself longing for the old days, when AT&T was the only game in town - or the country, for that matter.
I received a call from my phone company about a week ago. It turns out that my DSL contract is up at the end of the month. To be honest, I didn't even know I had a contract for DSL. I thought I just signed up for it - end of story. The sales rep on the phone started asking rapid-fire questions about my current phone service and rattled off different types of phone service and rate...

Motorola Razr for CDMA Users
Motorola is marketing different phones for men and women. Moto?s newest line of pink and blue Razr offspring seems to assume that there are men who will prefer blue and women who will want the pink one. They?re probably right!
The classic Silver Motorola Razr captured the lion?s share of new cell phone buying over the past year or so, causing Motorola to encroach on Nokia?s enviable leading position.
Motorola is planning to cash in on its huge success with the razor thin look and feel of the original Razr v3. The NPD Group, a leading cellular market researcher, found that Motorola cell phone sales accounted for 30% of the 31.6 million cell phones sold in the third quarter of 2005. The Motorola V3i with iTunes software and the Pink and Blue cell phones promise to give Motorola an ever-increasing share of the...

Building Relationships By Phone
by: Rob Brown
The telephone has arguably done more to help sales professionals than any other invention in history. And still it is the most under-utilised tool in your toolbox. Note I don't say under-used, because if you're like most professionals, you are probably on the phone more than two hours a day. The question is, how effective are you at using the phone to move your prospects closer to the sale and going deeper with your clients/customers to generate more sales and cross-selling opportunities?
It's a fact that some people are naturally good on the phone. Others need to work at it. Here are some key skills and qualities you need to be good on the phone. You only need to be weak in one or two of these areas to undermine your performance and stop you getting excited about using the phone.
