Slow page loading, constant video buffering and errors in sending messages in instant messengers on an Android phone when using the Tele2 network most often indicate problems with the signal level, incorrect APN access point settings or temporary failures in the operation of towers operator.
In this article we will analyze in detail the main factors affecting the quality of connection in fourth-generation networks and newer. You will learn how to independently diagnose the access point settings APN, check the status of the 4G service and optimize the operation of your smartphone for stable data reception. It is important to understand that the problem does not always lie in the tariff plan or the actions of the operator.
Sometimes the culprit is the device software or specific operating conditions. We will look at step-by-step action algorithms that will help restore high connection speeds without the need to visit a service center. Follow the instructions carefully to eliminate the most common technical errors.
Problems with network coverage and signal quality
The first thing you should pay attention to when your Internet speed is low is the signal level displayed in the status bar. Even if the 4G+ or LTEicon is lit on the screen, the actual signal strength may be critically low. Operator Tele2, like other cellular companies, uses towers whose coverage area is limited by physical obstacles.
Thick concrete buildings, metal structures, basements and even dense tree foliage can shield radio waves. In such conditions, the phone modem constantly tries to maintain the connection, switching between towers or lowering the communication standard to 3G or E, which automatically reduces the data transfer rate to a minimum.
It is also worth considering the base station overload factor. During peak hours, when there are a large number of active subscribers in a given location, the channel capacity is divided among all users. This is especially true for public events, shopping centers or residential areas in the evening.
⚠️ Attention: If you are on the move (in a car or train), frequent switching between cells may cause short-term connection breaks and a drop in speed. This is a normal physical phenomenon and not a malfunction of the SIM card.
To check the signal quality, it is recommended to go to the engineering menu or use specialized applications that show the signal level in decibels (dBm). A value above -80 dBm is considered excellent, and values below -100 dBm indicate a borderline coverage area where stable Internet operation is impossible.
Setting up an APN access point on Android
The most common technical reason for slow Internet operation is incorrect access point settings. The APN (Access Point Name) protocol serves as a gateway between your device and the operator’s network. If there is an error in these settings or they were reset after a system update, the phone will not be able to establish an optimal connection.
To correct the situation, you must manually check the settings. Go to the smartphone settings along the path Settings → Connections → Mobile networks → Access points (APN). The list must contain an active profile with the name Tele2 Internet or similar. If the list is empty or the settings look strange, you need to create them again.
In the field Name you can enter any value, for example, Tele2. The APN field must contain the value internet.tele2.ru. Other fields, such as username and password, are usually left blank. The authentication type must be set to PAP or CHAP.
☑️ Checking APN settings
After making changes, be sure to save the new access point and select it by clicking on the circle next to the name. Then hard reset the device to apply the network settings. Often this action instantly restores normal download speed.
| Parameter | Value for Tele2 | Required |
|---|---|---|
| Name | Tele2 Internet | Yes |
| APN | internet.tele2.ru | Yes |
| Proxy | Not specified | No |
| Port | Not specified | No |
| Authentication type | PAP or CHAP | Recommended |
Influence of network type and modem mode
Modern smartphones support various communication standards, from 2G to 5G. Sometimes the device mistakenly gets stuck on an outdated standard without switching to a faster one, even if the coverage allows it. This may occur due to a failure in the network selection algorithms or power saving settings.
You need to make sure that the mode 4G/3G/2G (auto) or LTE/WCDMA/GSMis selected in the mobile network settings. If the “3G Only” or “2G Only” mode is selected, the Internet speed will be limited by the technical capabilities of these standards, which are significantly inferior to LTE.
In some cases, forced mode switching helps. Try temporarily setting the mode to "4G Only", wait a few seconds, and then return to automatic selection. This will force the modem to re-register in the network and receive a fresh IP address from the base station.
If your phone supports 5G, but this network has not yet been deployed by Tele2 in your city, try temporarily disabling 5G mode in the settings. Finding a 5G tower that doesn't exist can drain your battery and interfere with a stable 4G connection.
It's also worth checking to see if Airplane mode is accidentally activated. Sometimes the icon disappears from the status bar, but the radio interface remains locked by software. Turning airplane mode on and off through the notification shade is a quick way to restart the radio module.
Background processes and traffic consumption
Often users do not notice that Internet speed drops due to the fact that the smartphone itself is actively consuming traffic in the background. The operating system Android and installed applications can synchronize photos, download updates, or back up data without the owner's knowledge.
Check data usage statistics in the device settings. Go to section Settings → Connections → Data usage. Here you will see a list of applications sorted by the amount of traffic consumed. If some application uses gigabytes in the background, it can “clog” the channel.
Particular attention should be paid to cloud storage, social networks and instant messengers. For example, Google Photos can start uploading an archive of high-quality images immediately after connecting to a mobile network, if Wi-Fi restrictions are not configured.
⚠️ Warning: Some malware or low-quality applications can secretly mine cryptocurrency or send spam using your Internet connection. If you see abnormally high traffic consumption for an unknown application, remove it immediately.
To solve the problem, limit background data transfer for heavy applications. In the traffic usage menu, select the desired app and activate the option Background mode or Saving traffic. This will prevent the application from using the Internet when the phone screen is turned off.
Failure of the SIM card and equipment
The physical state of the SIM card plays an important role in the quality of communication. Old SIM cards that have been used for many years may have worn contacts or may not support modern encryption protocols and speeds used by the operator. If your SIM card is more than 5-7 years old, it is recommended to contact a communication store for a free replacement with a new one with support for 4G. The new card will provide more stable authentication on the network and improve the quality of voice communications and the Internet. Tele2.
If your SIM card is more than 5-7 years old, it is recommended to contact a communication store for a free replacement with a new one with support USIM and 4G. The new card will provide more stable authentication on the network and improve the quality of voice communications and the Internet.
The problem may also lie in the card slot or smartphone antenna. Dropping the device, moisture, or simply a manufacturing defect can lead to poor contact. Try to remove the SIM card, wipe its contacts with a soft cloth and insert it back, making sure that it is firmly seated.
How to check the serviceability of the SIM card?
Move your SIM card to another phone that supports 4G. If the problem with slow Internet persists on another device in the same location, then the problem is with the card or tariff. If the Internet is fast, the problem is in your smartphone.
In rare cases, the problem may be in the radio module of the phone itself. If the device overheats, it can artificially reduce the transmitter power to protect components, which leads to loss of signal and speed.
Features of the tariff plan and service
Don't forget about the terms of your tariff contract. Operator Tele2, like many others, has a fair traffic usage policy. If you have exhausted the high-speed gigabyte package provided in your monthly payment, the speed may be reduced to 64 kbit/s or 128 kbit/s until the end of the billing period.
You can check the rest of the package through the official application My Tele2 or USSD command. Sometimes the speed decreases automatically when a certain consumption threshold is reached, even if visually the package does not seem to be exhausted (for example, due to traffic accounting in roaming or partner services).
There are also options that can affect the priority of traffic. Some unlimited plans have hidden restrictions on Internet distribution (modem mode) or the use of torrent clients. When trying to use these functions, the speed may be reduced programmatically on the operator's side.
⚠️ Attention: Tariff terms and service rules can be changed unilaterally by the operator. Always check the current conditions of your package in your personal account or official application to eliminate financial speed restrictions.
If you suspect that the speed is limited due to the end of the package, you can purchase additional traffic or use the "Unlimited for the night" service or similar options to restore access.
Replacing the old SIM card with a new one in the salon communication often solves the problem of unstable Internet, as new chips work better with modern 4G/LTE encryption standards.
Additional optimization methods
There are a number of less obvious settings that can affect network performance. For example, enabled mode Energy savings may limit the operation of the AC adapter to extend battery life. Disable this mode and check the speed again.
It is also worth clearing the network services cache. Go to Settings → Applications → Show system processes, find services related to telephony or connections (for example, Telephony Service), and clear their cache. This will not delete your contacts, but will clear temporary network errors.
As a last resort, you can reset your network settings. This feature will return all Wi-Fi, Bluetooth and mobile network settings to factory defaults. The path to the function is usually located in the section Settings → General settings → Reset → Reset network settings.
Remember that the phone software must also be up to date. Manufacturers regularly release firmware updates that fix modem errors and improve compatibility with the networks of various operators.
Frequently asked questions (FAQ)
Why is the Internet slow only at certain times of the day?
Most likely, this is due to the operator’s base station being overloaded during the hours peak (weekday evenings). During this time, many people are using the network at the same time, and the bandwidth is divided among all subscribers. This is a temporary phenomenon that goes away at night or in the morning.
Does the case affect the speed of Tele2 Internet?
Yes, it can. Cases with metal elements, magnetic clasps, or very thick rubberized cases can shield the signal from the smartphone antennas, which are often located around the perimeter of the case. Try removing the case and checking the speed.
What to do if changing the APN settings does not help?
If changing the APN does not help, try removing the SIM card and inserting it into another smartphone. If the problem persists, contact Tele2 support to check the line and replace the SIM card. If everything works on another phone, the problem is in the hardware or firmware of your Android device.
Can a virus on your phone slow down the Internet?
Yes, malware can use your connection for its own purposes (botnets, mining, spamming), clogging the channel. Check your phone with an antivirus and remove suspicious applications, especially those that were not installed from the official Google Play store.
Why did the Internet begin to work worse after updating Android?
After a major system update, network profiles may get lost or energy saving algorithms may change. It is recommended to reset the network settings (not a complete reset of the phone, but the network) and re-create the APN access point manually.
