Smartphones, tablets, netbooks, readers are portable devices that are practically pointless without access to the Internet. All of these devices have two ways to connect to high-speed Internet - via a 3G device and a Wi-Fi network.
Built-in 3G modem
3G is a 3rd generation cellular connection for high speed data transfer when connected to the Internet. 3G modem is a device for connecting to the Internet in 3G networks. Not all laptop models have this modem built-in.
In Russia, Internet providers in the 3G network are mainly mobile operators of the “big three”: Beeline, MTS and Megafon. Since 2013, the 3G network has been launched by OJSC Rostelecom.
The built-in 3G modem is a module inside the device with an external slot for a SIM card. It is very easy to access the Internet with a built-in 3G modem. To do this, insert the SIM card into the device and activate mobile data transmission. If the Internet parameters are lost for some reason, it is easy to configure them through the menu of the device. In an extreme case, this issue can be resolved in cell phone stores.
Benefits of a built-in 3G modem
Mobile Internet is indispensable in places where there is no access to a Wi-Fi point. The maximum speed in 3G networks reaches 3.6 Mb / s. This speed is enough to watch videos in good quality.
The built-in 3G modem can be easily replaced with an external modem. True, there are a couple of nuances.
First, external 3G modems have a USB connector. Accordingly, your device must have a USB port or an adapter to it. Without these, an external 3G modem cannot be connected to the device.
Secondly, the installation of 3G modems is not particularly difficult, as long as it is not about the Android operating system. The fact is that Android recognizes a modem as two devices: a USB flash drive and a modem. A conflict occurs due to which the device cannot work with the modem. This problem, in principle, can be solved, but you will have to tinker a lot.
Another alternative to the built-in 3G modem is a 3G router. It works in the same way as a modem from a SIM card. The connection between the router and the device is made via a Wi-Fi receiver. The 3G router can work from 3 to 7 hours without recharging. The advantage of the built-in 3G modem over the router is obvious - it is not very convenient to keep track of the charging of two devices.
And one more thing - the built-in 3G modem will never be forgotten anywhere. Internet access is always at hand along with a tablet or other gadget.
Disadvantages of the built-in 3G modem
The main disadvantage of the built-in 3G modem, which also applies to other 3G devices, is the possible absence or weak coverage of the 3G network. This is fraught with low data rates, and sometimes a complete lack of the Internet. Therefore, when choosing a SIM card, familiarize yourself with the coverage maps of all telecom operators in your region. Find out if 3G Internet services are available at all in your locality.
Another drawback is the relatively high price for using the Internet. In large cities, the competition in the 3G network is quite high, which makes it possible to use mobile Internet at reasonable prices. In any case, to reduce mobile Internet costs, it is recommended to use unlimited Internet options, especially if you use these services all the time.
As for the use of the Internet in roaming, this is a separate topic.
In international roaming, it is recommended to disable Internet access via a 3G modem altogether. using native mobile internet abroad can be very costly.
Before you decide to leave your hometown, consult your operator about the cost of traffic and additional services that can reduce the cost of the Internet in roaming.
