The presence of a 3G or 4G module on the tablet is a convenient option that allows you to use the device when it is impossible to connect via a wireless Wi-Fi network. However, the price of devices with 3G is much higher than without the support of this technology. Therefore, before purchasing a tablet, you should decide whether you need a 3G module on your device, or you better save a few thousand rubles.
Using 3G
The 3G and 4G module allows you to access the Internet using the data transmission channel of the mobile operator. Thus, a device with a 3G module is able to access the Internet at any point where there is coverage of the selected communication service provider. However, wireless data transmission over a mobile operator's network has a number of disadvantages that may affect your decision to purchase a device.
Network coverage
If you often go to the dacha, to nature, go fishing or are far out of town, the speed of the Internet available via 3G or 4G will be minimal. This is due to the fact that the towers of mobile operators are most often concentrated in the city and when leaving its territory, the connection speed will drop significantly, which in some cases may even lead to complete inaccessibility of the Internet.
If you are often out of town, you should not buy a device with 3G or 4G support - it will be an extra waste of money for an unused function.
Places to use the tablet
If you intend to use your tablet computer at home, in the office or at a party, where there is a Wi-Fi connection, you will not need a 3G module either. The Wi-Fi connection has better stability and higher actual data transfer rate. If you want to go online from your tablet computer outside of a room that has wireless internet, you can occasionally use the Hot Spot function of your Android, iOS, or Windows Phone mobile phone. When the function is activated, the device converts the existing 3G signal from the operator's SIM card into Wi-Fi mode and you can connect to the Internet using a tablet.
As an alternative to a 3G tablet, you can purchase an additional USB router, which will save you on the purchase of a device and will enable you to access the Internet wirelessly if necessary.
Additional expenses
By purchasing a 3G or 4G SIM-card, you will carry out regular top-ups to pay for Internet services. Carriers rarely provide completely unlimited wireless services, and if you exceed a certain limit of traffic, you may need to pay an additional fee to provide more data. Using a SIM card in a tablet can increase your mobile phone bills and become another expense in your budget.
