mobile data from Tele2 on smartphones Samsung usually configured automatically after installing a SIM card, but sometimes users encounter problems: no connection, low speed or errors authentication. The reasons may lie in incorrect settings APN (access points), outdated firmware version, conflicts with VPN, or even in the features of a specific model Samsung Galaxy (for example, Galaxy S23 or Galaxy A54 require separate manipulations with the network mode).

In this article we will look all methods of manually setting up Tele2 Internet from the basic APN configuration to solving rare errors like “No registration on the network” or “Emergency calls only.” You will also learn how to check 4G/5G coverage in your region, optimize connection speed, and what to do if the Internet works, but sites do not open. The instructions are relevant for all modern smartphones. Preparation: checking the SIM card and network coverage Samsung on Android 12–14, including models with support eSIM.

1. Preparation: checking the SIM card and network coverage

Before setting up the Internet, make sure that the problem does not lie in the hardware or tariff. Here's what you need to do:

  • 📱 Check the installation of the SIM card: on models Samsung Galaxy with a hybrid slot (for example, Galaxy A34 or Galaxy S22), make sure that the card is inserted into the slot SIM1 —it usually supports 4G/5G. If you use eSIM, activate it through the app Tele2.
  • 📡 Check coverage area: go to the website Tele2 or the operator's application to check whether 4G/5G is supported in your region. For example, in some areas Tele2 can automatically switch subscribers to partner networks (for example, MTS or MegaFon), which requires separate APN settings.
  • 💳 Check tariff: even if the Internet is included in the package, some tariffs (for example, “My Tele2” or “Everything for 500”) may block access to certain resources or limit the speed after the limit is exhausted.

If the SIM card is new, wait for an SMS from Tele2 with automatic settings (usually arrives within 5-10 minutes). If the message has not arrived, proceed to manual setup.

⚠️ Attention: On smartphones Samsung with two SIM cards (Dual SIM), mobile data can be assigned to only one slot by default. To change this, go to Settings → Connections → SIM card manager → Mobile data and select the desired SIM.

2. Automatic Internet setup Tele2

The easiest way is to let the system configure everything on its own. To do this:

  1. Open the application Phone and dial the combination: *135# → press the call button.
  2. In the menu that appears, select "Internet settings" (or "APN»).
  3. Confirm receipt of the settings - an SMS with the configuration will be sent to your phone. Save it.
  4. Restart your smartphone (required!) for the changes to take effect.

If the Internet does not work after reboot, check:

  • 🔄 Network mode: go to Settings → Connections → Mobile networks → Network mode and select 4G/5G (recommended). On older models (for example, Galaxy J6), you may need to manually select LTE only.
  • 📶 Roaming: if you are on a trip, enable National roaming in the same settings.

3. Manual APN setup for Tele2 on Samsung

If the automatic setup does not work, you will have to enter the parameters manually. Open:

Settings → Connections → Mobile networks → Access points (APN)

Click "Add" (or "+") and fill in the fields according to the table below. Leave those parameters that are not specified blank:

Parameter Value for Tele2
Name Tele2 Internet (or any other)
APN internet.tele2.ru
User name do not fill in
Password do not fill in
Authentication type PAP or CHAP
APN type default,supl (for MMS add ,mms)

After filling out, save the settings, select the created access point in the list and restart the phone. If the Internet does not appear, check:

Is the access point saved as active?

Is mobile data included in the quick settings panel?

Are there any traffic restrictions in Android settings? (Settings → Connections → Data usage)?

Is a VPN or firewall (for example, Avast or Kaspersky) blocking the connection?-->

⚠️ Attention: On some firmware Samsung One UI (for example, on Galaxy S21 s Android 13) after manually entering the APN, you may need reset network settingsTo do this, go to Settings → General management → Reset → Reset network settings.

4. Setting up 5G on Samsung for Tele2

If your smartphone supports 5G (for example, Galaxy S22+, Galaxy Z Fold4 or Galaxy A53 5G), but the network does not catch, follow these steps:

  1. Make sure that your SIM card 5G-ready. Old cards (issued before 2020) may not support the new network. Replace it in the cabin Tele2.
  2. Enable 5G in the settings: 
    Settings → Connections → Mobile networks → Network mode → 5G/LTE/3G/2G (auto)
  3. Check whether the option VoLTE (voice over LTE) is enabled, since without it 5G may work unstable. Path: 
    Settings → Connections → Mobile networks → VoLTE calls

If 5G does not appear, the reasons may be the following:

  • 📍 Lack of coverage: even in Moscow, 5G from Tele2 is not available everywhere. Check the coverage map on the operator's website.
  • 🔄 Conflict with Wi-Fi: turn off Wi-Fi and try connecting to 5G again.
  • 🔧 Firmware restrictions: on Some models (for example Galaxy Note 20) 5G is disabled by default to save battery. Enable it in Settings → Device maintenance → Battery → Adaptive battery mode.
💡

If 5G is unstable, try manually selecting the network band. To do this, enter the code ##4636##in the engineering menu, go to “Phone Information” and select NR/LTE/TD-SCDMA/GSM in the “Set preferred network type” section.

5. Solving common errors

If the Internet does not work even after setting up an APN, here are the common errors and their solutions:

Error Cause Solution
"No Internet connection" Incorrect APN or no registration on the network Check the APN settings (section 3) and restart the phone. If it doesn’t help, insert the SIM into another smartphone for a test.
“Emergency calls only” SIM card is not activated or blocked Call 611 (support service Tele2) or check the balance via *105#.
There is Internet, but sites do not open Problems with DNS or traffic blocking Try changing DNS to 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare) in Wi-Fi/mobile network settings.
Low speed (Edge instead of 4G) Network overload or tariff restrictions Turn on Flight mode for 30 seconds, then turn off. If this does not help, contact the operator.

You can also use the hidden menu for diagnostics Samsung:

*#0011#

The current state of the communication module is displayed here. If the line Serving Cell indicates LTE or NR5G, but the Internet does not work, the problem is in the APN or operator blocking.

What to do if the Internet is lost after updating Android?

After major updates (for example, smartphones Android 12 on 13) smartphones Samsung can reset APN settings. In this case:

1. Delete all saved access points.

2. Request automatic settings via *135# (section 2).

3. If that doesn’t help, reset the network (Settings → General management → Reset → Reset network settings).

6. Optimizing connection speed and stability

If the Internet works, but is slow or cuts out, try these methods:

  • 🔄 Switch network type: sometimes forced mode LTE only (without 3G/2G) gives a more stable connection. Path: Settings → Mobile networks → Network mode.
  • 📶 Disable automatic network selection: manually select Tele2 in Settings → Mobile networks → Network operators. This will help avoid switching to affiliate networks with low speed.
  • 🔋 Check the power saving mode: on Samsung functions like Adaptive power saving can limit background traffic. Disable them in Settings → Device maintenance → Battery.
  • 🛡️ Disable VPN and firewalls: applications like NordVPN or AdGuard may conflict with the mobile data.

To check the real speed, use applications Speedtest by Ookla or nPerf. If the speed is below 10 Mbit/s in the 4G zone, contact support Tele2 —the problem may be on the operator’s side.

💡

If after all the manipulations the Internet still does not work, the cause may be a hardware malfunction of the communication module. In this case, contact the service center Samsung for diagnostics.
