Modern tablet computers are equipped with many means of communication, including work in 3G networks. There are several ways to check for this option.
First, you need to carefully study the instructions for this device. At the very beginning, the technical specification of the tablet computer is indicated. If the declared function is absent, then it does not support work in 3G networks. It happens that 3G is declared in the technical characteristics of the device, but in fact it is not. This is a reason to contact the store with a demand for a refund for the sale of low-quality products.
If there are no instructions, then you need to carefully study the device case. It must have at least 1 slot, which must fit a SIM card. It is similar to that used in cell phones and communicators. With this connector, the tablet is able to access the Internet and even support calls. But this does not mean that the tablet supports the 3G standard. To make sure that the tablet still works on the broadband Internet, you need to turn on the tablet with the inserted SIM card and look at the network indicator. It is usually located in the far right corner of the screen. The abbreviation 3G may appear next to the network bars, or the Latin letter N.
If one of the indicators is on the screen, then this tablet supports 3G network. The letter H means that the tablet is using the HSDPA data transfer protocol. This protocol is based precisely on 3G networks. It happens that the SIM card does not support the specified standard. It can be replaced free of charge by the mobile operator in the office. All you need to do is bring your ID with you.
In order for the tablet to work in 3G networks, you need a SIM card that works with this standard. If there is none, then it is enough to contact the cellular operator to purchase it. It is worth choosing a suitable unlimited tariff in order to minimize spending on the Internet. The best unlimited mobile Internet tariffs on the Russian market are offered by Megafon, MTS and Beeline. The first one compares favorably with all the others, as it is a pioneer in the implementation of 3G networks in Russia. Also, under the brand of this cellular operator, a whole line of tablets that support 3G is produced.
Since March 2013, the active introduction of 3G + cellular networks has begun in Russia. The tablet computer market reacted violently to this event and launched many devices on the market that support 3G + SIM cards.
