If you are constantly on the go, purchasing a 3G wireless card is definitely worth it. Imagine yourself lying on the beach and being able to Facebook and send emails. Can you see yourself being able to check your website, stay in touch with clients and your small business anywhere you go? This is all possible thanks to 3g cards that are now widely available and have made internet connection so much easier.

There are two main types of 3G wireless cards. You can buy a USB wireless card that can you can plug into a USB port and use to access the web. This type of card you can use on both your laptop and PC, because even slightly older PCs have USB ports. The second kind is an internet access card that you can slide into a PC card slot or ExpressCard slot for newer notebook computers. Both types of cards will give you instant internet connection. Get the card that will work best with the type of computer that you have. Also go online and read reviews about different cards and manufacturers and choose the one that supplies a sturdy and durable product that will get you online fast and that you won’t regret buying.

A 3G wireless card has a 3G modem in it that will allow you to connect to broadband internet in no time using your cell phone carrier’s network. This means that you can online anywhere you get mobile phone reception. So for example, while you may be able to access the web from the shore on the beach, you might not if you go out on a boat because usually only satellite signals work out on the water. Use common sense, but most places should be fine.

Although you can get internet connection wherever you would normally get cell phone reception, this doesn’t mean that you can get reliable service and similar speeds everywhere. This will depend on your carrier’s coverage, its bandwidth which is related to the 3G’s high speed WAN interface. For example, if you are in the US, and use T-mobile as your 3G mobile wireless network, you might not be able to access the web, while a Verizon or Sprint subscriber could at the very same location. When looking into 3G wireless cards, ask about the carrier’s network coverage and available bandwidth. Is it extensive? Is it reliable? How well equipped is it with 3G networks?

Many carriers boast about their wireless cards using 3G networks, but in reality, they mostly use GPRS or EDGE technology and only sometimes will you be able to access 3G networks. Most wireless carriers configure their internet so that it can upgrade or downgrade your connection in an instant. For example your 3G wireless card can connect to GPRS if 3G is no longer available and vice versa. This is done automatically, and is very convenient. So, all of this will affect the kind of speed that you will get with your 3G wireless card. You will notice that in some places you will have a lot of bars filled up and sometimes you will only have one, and sometimes you might even get disconnected. This will all depend on the coverage of your wireless carrier, and the type of network that they use.
