Operator frequency range
The technology works both with the ranges of one standard (band), and with several. Not only subnets of different bands can be merged, but also of different standards. For example, in this way you can connect to the FDD subnet of Band 3 and TDD subnetwork of Band 38. But not all devices are able to cope with the task at hand. iPhone won’t work like that.
Four frequency ranges are allocated for fourth-generation networks, each of which is assigned its own number according to the 3GPP classification:
- 1800 MHz. 3;
- 2600 MHz. 7;
- 800 MHz. 20;
- 2600 MHz. 38.
Today, frequency aggregation on Samsung is possible in the following combinations:
- Megaphone. 37, 77, 377;
- on MTS. 37, 338;
- Beeline. 37.
The first devices supporting this technology work with numbers 3 and 7. Another option is 3, 7 and 20. Galaxy S10 supports LTE FDD and TD (Band 1, 2, 3, 4, 5, 7, 8, 12, 13. 17, 18, 19, 20, 25, 26, 28, 38, 39, 40, 41, 32). But the technique works only on the territory of Moscow and St. Petersburg.
What is frequency aggregation?
The technology is a connection mode when a router built into a mobile phone connects simultaneously over several channels. In this case, the powers are summed up. In fact, information arrives and is sent in several directions, which makes it possible to make the LTE connection faster.

Aggregation of frequencies is available only on some Samsung models and top-end modifications of their direct competitors. Basically, these are flagship smartphones. It is also important that the resources accessed by the user can support high speeds. Otherwise, the effect of the technology will be zero, but the battery consumption will increase.
How frequency aggregation works
Mobile operators provide connections in various ranges (Band 3, 7, 20 and others). A separate company reserves a certain limit. As an example: for transmission, signalmen occupy 2500-2570 MHz, and for receiving. 2620-2690 MHz. Within these limits, the user’s modem will operate.
But the amount of resources is limited, and the number of consumers who can simultaneously connect to the tower is also limited. Accordingly, operators are moving to narrower “corridors” (1, 5, 3, 5, 10, 15 or 20 MHz). This increases the number of available connections, but then the throughput of the system drops. Aggregation of frequencies on Samsung and other devices allows you to get one, but wider, and, therefore, faster.
How to enable frequency aggregation on Samsung
Aggregation of frequencies on Samsung allows you to improve the quality of surfing the Internet. So Huawei on the Mate 20 Pro announces up to 1.4 Gbps. The Galaxy S10 promises up to 2 Gbps. Similar parameters are close to 5G, because smartphone manufacturers talk about 4.75G technology.
How to enable frequency aggregation on Android Samsung
Aggregation of frequencies on phones from Samsung and other brands is activated through the setup menu. Here they sequentially go to “Connections”. “Mobile networks”. to the “” or “Additional” tab, and then in the appropriate point the toggle switch is moved to the working position.
Then the preferred network mode is set: “auto LTE / WCDMA / GSM”, “auto WCDMA / GSM”, “only GSM”, “only WCDMA”. The exact value depends on the service provider.
A review of the Samsung Galaxy S10 showed that frequency aggregation would be difficult in Russia. If the described option does not work, then advanced users replace (add) the 00028874 file. Initially, a full EFS backup is performed. Tuning is subtle and can cause serious damage to vehicles.

If you have a working SD card in your phone, you can transfer apps and other data to it. The main requirement for the operating system is Android (not lower than version 4.2.2).
Transferring applications to Android is possible provided:
- They were installed by you personally.
- The developer has taken care of the possibility of transferring software files to another location.
In other cases, it will not work to move the application in a regular way. But there are other possibilities. let’s go further.
The utility differs from its counterparts in the function of mass transfer of installed software. In addition to the transfer of “AppMgr III” can massively for selected applications:
- Clear cached data.
- Stop and hide unused software.
- Inform immediately whether it is possible to transfer software from the list or not.
- Sort installed software by main criteria.
You can transfer data using the buttons in the utility header. Works with Android 4 and higher, but may not be compatible with some OS skins (e.g. Xiaomi).
Transfer via “Settings
On some Samsung models, you can transfer applications to the memory card in the smartphone settings. Let’s see how this is done:
- Go to settings and select the “Applications” section.
- Select the software that you want to save on the SD card through the dispatcher.
- Check the box next to “Memory card”.
- Complete the transfer via “Export Classic” to Samsung.
The Link2SD utility is rather crude, so it can transfer any application indiscriminately. But after the transfer, it is not a fact that it will continue to work correctly. For normal operation of the utility, you need “ROOT”.
- Bulk software transfer to SD card.
- Bulk removal and reinstallation of software.
- Bulk flush cached data.
- Removing or installing the label “system” in applications.
Basic commands can be found under the “Menu” button.
How to move photos, videos, applications and music from the phone memory to the memory card
Hello everyone! How can I transfer apps and other data from phone memory to memory card if my device is running out of space? For smartphones with the Android operating system, there are several solutions to this problem. And we will consider them in detail in the article.
