The situation when a smartphone running Android suddenly loses mobile data speed from the operator Tele2is one of the most common complaints from subscribers. Users are faced with the fact that the indicator 4G or LTE is on, pages take forever to load, and the video is interrupted at every step. This is annoying, especially if the tariff plan offers high data transfer speeds.
The problem is rarely caused by one single reason. Most often, this is a combination of factors: from incorrect settings of the access point APN to physical clogging of the SIM card slot or temporary overloads of the cell tower in your area. In some cases, the culprit is the smartphone itself, which incorrectly switches between communication standards.
In this article we will analyze in detail all possible scenarios for a drop in speed and offer step-by-step diagnostic instructions. You will learn how to check network parameters, update the modem firmware, and what hidden settings can block full access to the World Wide Web.
Diagnostics of coverage and network type
The first step should always be checking the signal quality. Even if all the signal “sticks” are displayed on the smartphone screen, this does not guarantee high speed. Operator Tele2 The 4G network is actively developing, but in some remote areas or inside buildings with thick walls, the device may automatically switch to an outdated standard 3G or even EDGE.
Check the connection status in the notification shade. If you see the icon H+ or 3G, the speed will be limited by the technological capabilities of this standard, regardless of your tariff. In dense urban areas, a “cage” effect often occurs when the phone constantly jumps between towers, trying to find the best signal, which leads to disconnections.
Sometimes the problem lies in the overload of the base station. In the evening hours, when traffic is at its maximum, the capacity of one tower is divided among all connected subscribers. This is especially true in residential areas and large shopping centers.
- 📡 Check whether the icon 4G/LTE in the status bar is lit.
- 🏙️ Try going out into an open space or going to a window to improve reception.
- 🔄 Restart your smartphone for forced re-registration in the operator's network.
⚠️ Attention: If you are in an area of uncertain reception, the smartphone may waste battery power in attempts to maintain a signal, while the Internet speed will be critically low. In such cases, it is better to temporarily switch to the "3G Only" mode to stabilize the connection for simple tasks.
Checking and setting up the APN access point
The most common technical reason for low speed is incorrect access point settings APN (Access Point Name). These settings tell your device which gateway to connect to the Internet. Tele2. If the settings are lost after a system update or manual editing, the phone may be using an outdated or slow gateway.
To correct the situation, you need to go to the mobile network settings. The path may differ depending on your model Android-smartphone, but usually it looks like this: Settings → Connections → Mobile networks → Access points (APN). Here you should see a profile with the name Tele2 Internet.
Make sure that the value is entered in the "APN Type" field default,supl. If there is something else there or the field is empty, the Internet will be unstable. Also check the "APN Protocol" field - it should be set to IPv4/IPv6 for maximum compatibility with modern networks.
☑️ Checking APN parameters
If the profile is missing or editing does not help, try deleting all existing access points and creating a new one manually. Enter your name Tele2 and write in the APN field internet.tele2.ru. Leave the remaining fields blank or at default, then save the settings and select this profile as active.
After changing the APN settings, be sure to turn Airplane Mode on and off so that the changes take effect immediately without completely rebooting the device.
The influence of the tariff plan and traffic restrictions
Do not forget that the telecom operator has the right to limit the speed based on the terms of your tariff agreement. Many unlimited plans Tele2 contain a fair usage clause (FUP). If you have used up a certain amount of high-speed traffic (for example, 15 or 30 GB), the speed may be reduced to 64 or 128 Kbps until the end of the billing period.
There are also restrictions on using the Internet in distribution mode (modem mode). If you connect a laptop or other gadget to your smartphone via Wi-Fi or USB, the operator can detect this and artificially reduce the speed, even if everything works quickly on the phone itself.
You can check the remaining packages and current conditions in your personal account or through the app My Tele2. Sometimes the speed drops due to the exhaustion of daily bonuses or promotions that were active previously.
| Type of restriction | Cause | Symptom | Solution |
|---|---|---|---|
| Exhaustion of the GB package | End of the monthly limit | Speed drops to 64 Kbps | Purchase an additional package or wait for a new month |
| Internet distribution | Violation of tariff conditions | Sites do not load on the connected PC | Disable distribution or change tariff |
| P2P blocking | Torrent restrictions | Torrent clients do not download | Using a VPN or changing the port |
| Account debt | Negative balance | Complete lack of access or low speed | Replenishment balance |
⚠️ Attention: The terms of tariff plans and traffic limitation policies can be changed by the operator unilaterally. Always check the current terms of your contract in the official application or on the operator’s website before purchasing additional options.
Hardware problems and condition of the SIM card
The physical condition of the SIM card plays a critical role in the quality of communication. Old cards of format Mini-SIM or Micro-SIMthat were cut by hand or simply worn out over time may have oxidized contacts. This results in lost data packets and slower speeds.
Also, if you have recently changed your phone, make sure the SIM card is inserted into the correct slot. On many dual-SIM devices, only the first slot (SIM 1) supports full operation in 4G/LTE networks at high speed, while the second slot can be limited to the 2G/3G standard for voice calls.
Try to remove the card, wipe the contacts with a soft cloth (without alcohol or aggressive chemicals) and insert it back until it clicks. If the card is very old (issued more than 5-7 years ago), it is advisable to replace it with a new one at a communication store Tele2. This procedure is free and saves your number and tariff.
How to check the SIM card version?
Insert the SIM into the phone and dial the command *155*00#. The reply SMS may contain information about the card status. However, the most reliable way is to visually inspect the chip: if it is severely scratched or the contacts are darkened, replacement is required.
Android system settings and background processes
Sometimes the problem lies not in the operator, but in the device itself. Background applications can consume the entire available communication channel. System updates, synchronizing photos in the cloud, downloading large files in instant messengers - all this creates a queue for data transfer, which is why the browser does not have enough (bandwidth).
Check the traffic saving settings. There is a feature that can aggressively limit background activity and speed for some applications. Go to Android there is a function Saving traffic, which can aggressively limit background activity and speed for some applications. Go to Settings → Connections → Data usage and look at the statistics: is there an application that has eaten up several gigabytes in the last few hours?
It’s also worth paying attention to the settings development. If you have developer mode enabled, check the "Background process limit" setting. Sometimes users accidentally set a restriction that interferes with the normal operation of network services.
- 📱 Disable Saving traffic in the network settings.
- 🛑 Close all applications running in the background through the multitasking menu.
- ⚙️ Reset network settings:
Settings → General settings → Reset → Reset network settings.
Resetting network settings will not delete your personal files or applications, but it will forget saved passwords for Wi-Fi and pairs of Bluetooth devices. Be prepared to enter them again.
The influence of VPN and third-party software
The use of block bypass services (VPN) is a common cause of slow speeds. Free VPN services are often overloaded, have narrow communication channels and route your traffic through servers in other countries, which inevitably increases ping and slows download speeds.
Even if you didn't explicitly run a VPN application, some antiviruses or "optimizers" may have built-in traffic protection features that work like a proxy. Try to completely disable all such apps and check the speed through the service speedtest.net.
Malware (viruses, miners) can also use your Internet channel for their own purposes. If your phone gets hot, slows down, and quickly discharges when the Internet is on, run a full scan of the device with an antivirus.
⚠️ Attention: When disabling VPN, remember the risks of accessing blocked resources. If speed is critical for your work, use paid, proven services with servers in your region, rather than free analogues with an unknown reputation.
Frequently asked questions (FAQ)
Why does the speed drop only in the evening?
This is a classic sign base station overload. In the evening hours (from 19:00 to 23:00) the load on the network is maximum, since most subscribers are at home and consuming content. The operator cannot instantly expand the channel, so the speed is divided among all users of the tower.
Will changing the phone's IMEI help speed it up?
No, that's a myth. Changing IMEI does not affect the prioritization of traffic by the operator Tele2. Moreover, changing the IMEI is illegal in many countries and can result in the device being blocked from the operator's network if it is detected as a clone of another phone.
How to enable 4G Only mode on Android?
Usually this option is hidden. You need to go to the engineering menu by typing the code in your phone ##4636##. Select "Phone Information", find "Set up preferred network type" and select LTE Only. Remember that in this mode, incoming calls may not go through if VoLTE is not enabled.
Does the case affect the Internet speed?
Yes, it can. Cases with metal inserts, magnetic clasps, or too thick a layer of plastic can shield the smartphone's antenna. Try removing the case and performing a speed test - if the result improves, the reason has been found.
What to do if nothing helps?
If you checked the APN settings, replaced the SIM card, rebooted the device and made sure there are no tariff restrictions, but the speed remains low - contact technical support Tele2. Perhaps maintenance work is being carried out in your area or there is an accident on the line.
