The growing business needs demand businesspersons to travel to various countries. If you are a frequent traveler, you might have already experienced huge phone bills after calling your overseas friends. Hundred dollar bills for a few minutes of overseas calling are not something new if you are using the same local card in another country. International phone cards help you to call any country at low prices. Rather than paying one dollar or more for a minute, you will be charged two or three cents a minute using international phone cards.

Need for international phone cards

The common SIM card you use in your GSM has a microchip, enabling connection between the caller and the called person. The geographic locations and the call duration are tracked by this card, and it is sent to the mobile service provider. If you call an overseas number, you will be charged heavily per minute. If you take this mobile to another country, you are entitled to pay heavy roaming fees and the call rate is also high. Some people may advise you to buy a SIM card from the local country. This is unsuitable for a person who travels frequently to various countries. You cannot hold different SIM cards for different countries. International phone cards provide a solution to these problems with the single card for all countries.

International phone cards mimic the same technology used in your local card, but they are available as prepaid cards. This means that you will not get annoying bills at the end of the month. You know how much credit you want, buy the credit, and use it whenever you want. The prepaid cards can be topped up at any time from any place using the online top up feature. You have to login into your account and use the credit card to make the payment. Instantly, you will receive an e-mail indicating your purchase and the credits will be added to the phone card.

You can use international phone cards in any country provided the telecom company provides service in that country. This eliminates the need to buy separate SIM cards for different countries without compromising the low price advantage. You will always have a single SIM in your mobile, and you can use it on the go. Before visiting any country, check with the service provider if service is provided in that country.

The contact number remains the same irrespective of the country. The call rate is also low in comparison to the normal local cards you use. Your contacts don’t have to be confused with the number to contact you. With the same number, you can travel to almost all the countries in the world.

There is no hassle if you want to buy an international phone card. Many telecom companies sell international cards at affordable prices.

The use of various electronic devices is increasing in the modern world. Every home has devices such as telephones, modem, computer, printer, thermostat, and refrigerator and others. These devices have their own functionalities. It is not possible to invent a new device which performs all these functions but there are ways to connect these devices. Ubiquitous network connectivity has found ways to connect these devices. The devices can be interlinked, and they can be controlled from outside. These devices cannot be made to communicate with each other, but a centralized control system can be used to control various devices. This is the concept behind trivergence.

What is Trivergence?

Trivergence is an architecture which organizes several devices and networks. The latest networking technology can connect many different devices. Trivergence believes that the control of these connected devices can be found on the network apart from the device. This makes the stand alone devices to interact with each other using the available components. With a new control device, you can expect to control all your home appliances when you are away from your home. The users are frustrated with several devices for several purposes and they love centralized control minimizing their efforts. Many companies are working on trivergence concept to bring about a super device which can control many devices.

Examples of trivergence

Trivergence concept has been applied differently in several small devices. For instance, consider the latest model cell phone which has the capability to play music and video like a media player, take pictures like a camera, store messages and pictures like a computer and enable web browsing like internet browser. With a single cell phone, you can avoid many devices because you have all the features. The latest model cell phone is an excellent innovation, but it is not the ultimate device.

Apple uses buttons on iPod to buy and download music without using a computer connected to web. You can access a playlist in your computer if your computer and iPod are connected. TiVo allows the viewers to select shows from a web browser and view those programs in their television. The buttons on TiVo box enable a user to do this. The VoIP communication allows you to make calls to phones using web interface.

All these developments require buttons to be placed on the device. To use the networking advantage, the user has to use the buttons on these devices.

Future of trivergence

Trivergence architecture foresees to operate multiple devices without button pushing. The soft panels introduced by Accenture can be used in cars to control devices. The customers wanted super soft panels which can operate automatically controlling an array of devices. They wanted their car GPS to turn on the thermostat when they are close to their home. Such expectations are logical and with the evolving trivergence concept, these dreams will become true one day. Many new trivergence devices with capabilities to control many old and new devices will be available in the future. In the upcoming years, customers can control all their devices using a super soft panel as many companies are seriously working on trivergence.

Phone cards date back to the mid 1970s, when they were used in Italy for the first time. Two broad types of phone cards exist: prepaid phone cards and credit phone cards. A prepaid system is the most popular phone card system in use today, which does away with the need of billing after a phone call, as users can make phone calls within the stipulated value that the phone card carries until the balance amount is exhausted. These phone cards are disposable, and the user simply discards such a card after use. Reusable or rechargeable phone cards allow users to add value to their original phone card after successive exhaustion of the balance amount, so you can reuse such a card even after you have made calls worth of the initial prepaid amount.

Today phone cards offer the user a world of discounted rates when it comes to international calls as well as domestic long distance calls. Apart from this, there are a wealth of schemes that the user chooses from, which ensures a further reduction of calling rates. International prepaid phone cards are very useful for frequent travelers, who need not bother about carrier rates of the country they are traveling to, and use a phone card of a selected carrier. Prepaid phone cards are found at stores around the world, so you can just about pick one that suits your requirements best quite easily.

Most phone cards use a multiple step initiation of the call, which includes keying in the access codes, and destination number. There are variations in this, with some international phone cards requiring a sequence of numbers to be keyed in before the user actually gets through the call. Although this is supposedly a confusing process, you have to keep in mind the following when buying and using a phone card:

1. Always buy a phone card that you will find useful; there is no point paying for features that you will not use, or you might not be a frequent user of the same.
2. Obtain your PIN number and access codes either physically from the card, or via email.
3. Dial the Local Access Number or equivalent
4. Listen to the instructions
5. Enter your PIN number
6. Listen carefully for the balance and available call time information
7. Enter the number you wish to call

International phone cards tend to be continent or country specific. So, if you buy a UK calling card, then you can make calls to UK numbers alone, and cannot use it to call telephones in say France. Country specific phone cards allow for heavily discounted rates, and often bypass local telecommunications carriers to use their designated pre specified carrier. This is advantageous for people who want to avail of cheap rates and not the usual rates offered by the operators in that country, when calling from the same to another country. Students, travelers as well as local residents alike can take advantage of such a convenient phone card system.
