The evolution of tablets has taken a significant step forward. Modern devices have more and more functions, and often users want to see support for SIM cards in their tablet. How to choose a quality device that can make calls?
Display
Choosing a 7-inch Lenovo tablet, first you need to sort the devices according to the merits of the screen. Despite being the same size, displays can vary greatly between devices.
First of all, you should pay attention to the installed matrix. Lenovo most often uses IPS technology, but lower-quality displays can also be found among the products. For example, the image of a tablet with a TFT matrix will be much worse. The use of IPS technology will allow the device to have not only large viewing angles, but also increase the brightness of the image.
When examining a Lenovo 7-inch tablet, you should definitely study the resolution characteristics. Most of the company's devices have a minimum for this screen size of 1280 by 600 pixels. It is desirable that thisparameter was higher. High resolution will greatly improve the image and make the pixels invisible.
Pay attention to the protection of the display. A poor-quality coating will collect scratches and fingerprints. Reliable protection will allow the screen and its sensor to work as efficiently as possible.
Appearance
It is important that the "Lenovo" 7-inch tablets with a SIM card are assembled with high quality. Almost all devices hide slots for cards behind a special panel. If the assembly is not conscientious, the fasteners can quickly loosen. As a result, the Sim card will be left without proper protection. The mechanism of the fasteners and the quality of the material should be thoroughly checked.
Tablets weigh significantly more than phones and are more difficult to hold with one hand, so you should pay attention to the coating of the case. A heavy and slippery device can fall out during a call. It is advisable to choose a device made of matte plastic or with a corrugated panel.
Communication
Special attention should be paid to the quality of the device's antenna. The connection and operation of the tablet with cards depends on it. Some manufacturers, unfortunately, do not give a damn about this parameter.
When purchasing Lenovo devices, the owner will not worry about the antenna. The company pays enough attention to this detail. It should be noted that Lenovo 7-inch tablets with 3G cannot always make calls. In models such as the A3500, this feature is limited. Usercan send and receive messages, but calls are not available.
Many Lenovo representatives have as many as two card slots. However, not many devices can boast of having several radio modules. Accordingly, when you call, the second SIM will become inactive.
By choosing a 7-inch Lenovo tablet, the user will also receive many useful functions. In addition to Wi-Fi, the company's devices have smart GPS. Also, the owner will have access to GPRS-connection, which will allow you to connect to the Internet anywhere.
Autonomy
When buying a 7-inch Lenovo tablet phone, it is important to choose a model with a powerful battery. Since the device, in addition to the usual tasks, will also perform the duties of a smartphone.
Representative of the A3000-H company with two SIM cards has a battery of only 3500 maH. This is enough for a tablet to work, but not enough to play the role of a phone. When making calls and working with the Internet, the device will last a little more than two hours. This indicator will not particularly please the owner, which means that you need to choose a device with a more powerful battery.
Hardware
It must be remembered that, in addition to having a SIM card, a 7-inch Lenovo tablet must have a good filling. Fortunately, among the devices that support cards, there are many advanced devices.
The vast majority of Lenovo devices are powered by an MTK processor. Only its model and the number of cores differ. The A3300 tablet might be a good solution. This device supports SIM cards and has an impressive filling.
The "Lenovo A3300" has a familiar MTK processor, which has 4 cores with a frequency of 1.3 GHz each. Enough and RAM - a whole gigabyte. In addition to the ability to make calls, the user will receive a very frisky device capable of performing a lot of tasks.
System
The manufacturer does not particularly shine with a variety of platforms for devices. The company's tablets use exclusively "Android". Only the system versions differ, and this is very important for the device. The new version of the system allows more efficient use of the Lenovo 7-inch tablet. In addition to a well-designed and enhanced interface, the owner will receive a lot of useful programs and entertainment.
Price
The company can offer both budget and expensive options for devices that support SIM cards. The price of a 7-inch Lenovo tablet depends on the filling, functions and communication features.
One of the cheapest is the A7 model, its price is approximately six and a half thousand rubles. This is quite a budget and quite attractive option.
Representative of the flagships RV1-770M is much more expensive. The price of this incredibly powerful device is 24 thousand rubles. Quite an impressive amount, but it's a tablet and a phone rolled into one.
Package
Standard set of devices is rather scarce. In addition to the tablet, the user will receive a USB cable,adapter instructions. Together with more expensive representatives, a headset sometimes comes along. Having bought a cheap model, the owner will most likely have to purchase additional headphones.
A smart choice would be to purchase a protective case for the device. This will help not only protect the removable panels, but also avoid unwanted damage and scratches.
Emerging Issues
Describing the tablet "Lenovo" 7 inches reviews notice several significant shortcomings. One of these problems is the blocked call function in some models with 3G.
Also, budget devices sometimes have problems with the light sensor. Cheap tablets can't automatically adjust screen settings, which is pretty frustrating.
The system of devices also makes itself felt. Most tablets with a card have an "Android" "telephone" interface. This affects the adaptation of some games and programs. Apps have difficulty adjusting to display size.
A very common problem is the battery of the device. Batteries have enough capacity for the functions of the tablet, but the communication support spoils everything. In call mode, devices run out incredibly quickly, so the battery should be given due attention.

It is also important to study the features of the connection of the apparatus. Otherwise, however, the tablet selection method is the same as for smartphones.
