Have you ever noticed that in the top panel of your Androidsmartphone, instead of the usual letters 4G sometimes appears abbreviation LTE? Or vice versa - you see both terms in the network settings, but don’t understand what the difference is? This article will once and for all clarify what LTE in the phoneis, how it is related to 4G, and why the speed of your mobile data depends on its correct configuration.
Many users mistakenly think that LTE and 4G are two different communication standards that compete with each other. In fact, everything is much more interesting: LTE (Long-Term Evolution) is the technological basis on which the 4G network is built, but with important nuances in speed and coverage. Without understanding these nuances, you can use a smartphone for years at half its capabilities - for example, not suspecting that your Samsung Galaxy or Xiaomi Redmi is capable of downloading files 2-3 times faster.
In this article we will not only explain the terms in simple language, but also show you how to check support LTE your phone, turn it on manually (if the automation failed), and we will also look at typical problems - from lack of network to “jumping” speed. And yes, you will find out why sometimes it is better to force a switch to 3G, despite all the “advancement” of the fourth generation.
LTE and 4G: what is the difference and why is this important
Let's start with the main thing: LTE and 4G are not synonyms, although they are often used interchangeably. 4G (fourth generation of mobile communications) is a standard that promised theoretical speeds up to 1 Gbit/s. A LTE is technologywhich was supposed to bring us closer to this standard, but initially did not reach the declared characteristics.
Here are the key differences:
- 📡 LTE (up to the Advanced version) is “improved 3G” with a maximum speed of up to
100–300 Mbit/s. This is what smartphones most often show under the sign 4G (marketing ploy of operators). - 🚀 LTE-Advanced (4G+) - this is already real 4G with speed up to
1 Gbit/s, but it requires special equipment from the operator i smartphone support. - 🔄 4G (in marketing) is any LTE, even if it does not reach up to standard. Operators often write “4G” when in fact they are talking about basic LTE.
Why is this important to you? Because the version LTEthat your phone supports depends on:
- 📥 The speed of downloading files (for example, a movie in
Full HDin 2 minutes vs 10 minutes). - 🎮 Ping in online games (in LTE-Advanced it is lower than in the basic LTE).
- 🔋 Battery consumption (the smartphone spends less energy on a stable one LTE-connection than constant switching between 3G and 4G).
⚠️ Attention: If your smartphone was released before 2016, it may not support LTE-Advanced, even if the specifications indicate 4GCheck the chipset model (for example, Qualcomm Snapdragon 400 doesn't work LTE-A, but Snapdragon 820 - pulls).
How to check whether your Android smartphone supports LTE
Before setting up the network, make sure that your the phone is generally capable of working with LTE. Here are 3 reliable ways to check:
1. Through the Android settings
Open Settings → Network and Internet → Mobile network → Network type. If the list contains items like LTE, 4G or LTE/3G/2G (auto) . there is support. If only 3G and 2G your smartphone is outdated.
2. Through the characteristics of the model
Look at the specifications of your model on sites like GSMArena or 4PDA. Look for the lines:
- 🔍 Network:
LTE band 1/3/7/20...(numbers are supported frequencies). - 🔍 4G bands: if the list is empty. — LTE not supported.
3. Through the engineering menu (for advanced)
Enter the code ##4636##in the phone application, then select Information about the phone. data-i="113">there should be options with Set preferred network type there should be options with LTE.
Make sure that there is an "LTE" item in the network settings|
Check the model's characteristics on GSMArena|
Enter the engineering code ##4636## and find the section "Set preferred network type"|
Check the supported LTE frequencies with the frequencies of your operator-->
How to enable LTE on Android: step-by-step guide
If your smartphone supports LTE, but the network does not connect automatically, try turning it on manually. The instructions are universal for most devices (Samsung, Xiaomi, Huawei, Realme etc.), but there may be slight differences in the names of menu items.
Step 1. Open the mobile network settings
Go to Settings → Network and Internet → SIM cards and mobile networks (on some phones the path may be Settings → Connections → Mobile networks).
Step 2. Select network type
Find item Network type, Network mode or Preferred network type. Here you need to select one of the options:
- 🔄 LTE/3G/2G (auto) —recommended mode (automatic selection of the best network).
- 📶 LTE only — forced connection to 4G (may not work if the coverage is weak).
- ⚠️ Only 3G —use if LTE is unstable (for example, in metro).
Step 3. Save the settings and restart the phone
After changing the network mode, reboot the device - this will help avoid connection glitches. If LTE does not appear, go to the section “Why it doesn’t work.” LTE."
If your region has weak 4G coverage, but stable 3G, select the 3G/2G (auto)mode. This will save battery power, since the phone will not constantly search for LTE-signal.
Why LTE doesn't work: 7 reasons and solutions
You turned on LTE in the settings, but the smartphone stubbornly shows 3G or H+? Here are the most common causes and ways to eliminate them:
| Problem | Cause | Solution |
|---|---|---|
| No LTE icon | SIM card does not support 4G | Replace the SIM with USIM (check with your operator) |
| The network “jumps” between 3G and LTE | Weak 4G signal | Turn on the mode Only LTE or change operator |
| LTE is available, but the Internet does not work | Incorrect APN settings | Reset APN to factory defaults or configure manually |
| Low speed in LTE | Base station overload | Switch to 3G or wait for a less busy time |
| LTE is available, but the battery drains quickly | Constantly searching for a network | Disable automatic mode and select LTE only |
Additional checks:
- 📵 Make sure mode flight is off.
- 🔄 Reboot the phone - sometimes this resets communication module failures.
- 📡 Check the coverage of your operator on the map (for example, Yota, MTS, Beeline or Tele2 provide such services).
⚠️ Attention: If you use dual-SIM phone (for example, Redmi Note 10 or Samsung Galaxy A52), remember that LTE can only work on one SIM card at a time. In the SIM settings, select the priority card for 4G.
How to speed up LTE on Android: 5 working methods
Even if LTE connected, the speed may be disappointing. Here are proven methods for increasing it:
1. Forcefully enable LTE-Advanced (if supported) Some smartphones (for example, those with chipsets
Some smartphones (for example, on chipsets Qualcomm Snapdragon 8xx or MediaTek Helio G90T) can aggregate several frequencies to increase speed. To enable this feature: LTE-frequencies to increase speed. To enable this feature:
- Enter the engineering code
##4636##. - Go to
Phone information. - In the section
Set preferred network typeselectLTE onlyorLTE/TD-SCDMA/GSM auto.
2. Update the firmware
Manufacturers regularly release updates that improve the performance of modems. Check the software is up to date in Settings → System → System update.
3. Reset network settings
Go to Settings → System → Reset → Reset network settings. This will delete saved Wi-Fi networks and mobile data settings, but often solves problems with slow settings LTE.
4. Use applications to optimize your network
apps like Network Signal Speed Booster or Internet Booster & Optimizer help clear the DNS cache and optimize traffic routing. However, don't expect miracles - the speed increase is usually 10–20%.
5. Change location
Speed LTE highly depends on the load on the base station. If you are in the city center during rush hour, try moving closer to a window or outside - sometimes this increases the speed by 2-3 times.
The most effective way to speed up LTE is to use frequency aggregation (LTE-Advanced), but it only works on modern smartphones and in areas with good coverage.
LTE vs 5G: is it worth switching to the new generation?
With the advent 5G many users they wonder: is LTEoutdated? The answer depends on your tasks:
Advantages of 5G over LTE:
- 🚀 Speed up to
10 Gbit/s(in theory) versus1 Gbit/sy LTE-Advanced. - 🕒 Lower latency (ping up to
1 msagainst20–50 msto 4G). - 🌐 Ability to connect thousands of devices at one station (important for “smart” cities).
Disadvantages of 5G today:
- 📡 Limited coverage (in Russia 5G tested only in a few cities).
- 🔋 Increased battery consumption (modules 5G consume 20–30% more energy).
- 💰 Expensive tariffs (operators often charge for access to 5G above the standard package).
Conclusion: if you live in a metropolis and are willing to pay for speed, 5G may be justified. In all other cases, LTE-Advanced (aka 4G+) remains the optimal choice at least until 2026-2026.
When will full-fledged 5G appear in Russia?
The official launch of commercial 5G in Russia is planned for 2026–2026, but full coverage outside large cities is expected no earlier than 2030. So far, operators are testing networks in Moscow, St. Petersburg, Kazan and Sochi.
Frequently asked questions about LTE on Android
My phone shows the 4G+ icon, but the speed is the same as 3G Why?
Most likely, your operator is using a marketing trick: the icon 4G+ appears during frequency aggregation, but if the base station is overloaded, the actual speed may be lower. Check the coverage on your operator's map or try changing your location.
How can I find out which LTE frequencies my smartphone supports?
Look at the model specifications at GSMArena or enter the command ##4636##, then go to Phone information. The section Network will indicate supported bands (for example, Band 3, 7, 20).
Can I use LTE without a SIM card?
No, to connect to LTE an active SIM card with 4G support (preferably USIM). However, some operators (for example, Yota) offer virtual SIMs for tablets.
Why does LTE quickly drain the battery?
If the phone is constantly switching between 3G and LTE (for example, in conditions of a weak signal), this increases energy consumption. Solution: force select LTE only or Only 3G in the settings.
How to disable LTE if you don’t need it?
Go to Settings → Mobile network → Network type and select 3G/2G (auto) or 3G onlyThis will extend the battery life, but will reduce the Internet speed.
Now you know about LTE v Android-smartphones. All that remains is to put this knowledge into practice: check your network settings, optimize speed and enjoy stable Internet without any slowdowns. And if there are any nuances left, write in the comments, we’ll figure it out together!
