That is, the driver supplied support for OS Windows XP and Windows Vista OS. Installation is not complicated and rapidly detected by the computer when the pull the pair.

2. Modem warranty.

Do not forget this one thing. Some shop modem makes no warranty, so choose a store that provides a guarantee of modem you buy. Generally there is a guaranteed modem 6 Months to 1 year.

Choose a feature-rich modem, for example support with speed 3.6 Mbps and 7.2 Mbps. Can use the Micro-SD Card slot. USB Extension. Features Wireless Lan (Wifi). GPS features. Support External Antenna Indoor and Outdoor, etc..

But sometimes these features can lead to other problems on your modem, for example, the modem is always automatically connect to WiFi than the GSM. So if you're not too familiar with the extra features which I suggest should be given only the standard modem select.

4. Modem Model.

Do not be fooled by the petite and beautiful modem. Not all modems in the form of pretty good quality. Also avoid modem that can be folded, because the connector is more easily damaged USBnya.

5. Modem Software.

All modems come with software to configure your internet settings. Some modem software has a complete Internet setting. There are also some that can not be modified anymore settingannya (Modem Locked). Choose the modem that is easy and does not terlock settingannya by certain internet providers.

1. The price offered.

Important determining factor in choosing the internet provider. Today many scattered Internet package offered by the provider. Also do not be fooled by the lure of low prices. Because the typically low-cost internet packet network quality is also cheap. It never hurts to spend more money to get a good internet connection. Rather than spending time waiting for loading a web page.

Do not be surprised if you find a bad quality internet network in your home, but even your good friends at home. The point is, not all places have network coverage HSPA / UMTS good. Generally, the modem automatically lose your connection type from 3G to 2G 2G when the signal is much stronger case than 3G.

3. Internet package users.

Some of your friends might say that the internet package "A" is good. Maybe some of your other friends even said internet packet "B" is good. It can not be used as a benchmark. Because whether or not an internet connection is also influenced by the number of users (users) internet in the area. A tower (BTS) internet network GSM is generally only able to accept 40 simultaneous users at one time. So if your area booming internet users certainly affect your own so go get a slow internet network.

4. Speed ​​internet.

Modem in the market have a data transfer rate between 3.6 Mbps to 7.2 Mbps. This means that the transfer speed modems and base stations is 3.6 or 7.2 Megabytes per one second. But do not immediately get me wrong if you simply download speeds of about 256Kbps only. Transfer speed of your modem is true 3.6 or 7.2 Mbps to the BTS, but generally limit the speed of your internet provider of base stations to the Internet, so you get less speed.

Modem - (7.2Mbps) -> [BTS] - (256Kbps) -> Internet
