The problem is when a smartphone stops working effectively in modem mode with a SIM card. Tele2, is common and often baffles users. Network coverage appears strong, the 4G indicator is lit, but the speed on connected devices drops to critical levels or the connection is lost entirely. This doesn't always indicate a broken phone or a weak signal in a specific location; it could be due to specific network settings or data plan restrictions.
The situation is aggravated by the fact that modern operating systems Android And iOS They are constantly updated, changing the algorithms for working with network interfaces, and telecom operators adjust their terms of service. When you try to share the internet, your phone creates a local network, but the channel's throughput depends on how the mobile operator handles this traffic. In the case of Tele2 Hidden distribution control mechanisms are often triggered, which lead to artificial slowdowns.
In this article, we'll take a detailed look at the technical aspects that affect distribution quality and offer specific optimization steps. You won't have to wonder why everything worked yesterday but not today; we'll systematize your knowledge of the settings. APN, frequency ranges, and software conflicts. Understanding these processes will allow you to resolve most speed issues yourself.
Technical limitations and traffic throttling
The first thing the user encounters is a phenomenon known as throttling or artificial speed limitation. Telecom operator Tele2, like many others, has the right to limit data transfer speeds when using your phone as a hotspot if your plan doesn't allow it or if your GB limit has been reached. This isn't a malfunction, but a software limitation on the base station.
Often, the restriction takes effect unnoticed: you still see the 4G or LTE icon, but the actual speed drops to 64 or 128 kbps. This is done to prevent network congestion during peak hours and encourage upgrading to more expensive unlimited data plans. It's important to understand the difference between a weak signal and software-based channel throttling.
⚠️ Attention: Tariff terms may be changed unilaterally by the operator. Always check the current terms of your tariff plan in your personal account or mobile app, as data sharing rules may vary by region and connection date.
In addition, there is the concept of traffic prioritization. During periods of high load on the tower Tele2 Traffic from access points (tethering) may have a lower priority than traffic from the smartphone's internet connection. This leads to unstable ping and stuttering when watching videos on a connected laptop.
To diagnose this phenomenon, you can use specialized apps that measure speed at different times of day. If you notice a consistent drop in speed in the evening when you're trying to share Wi-Fi, it's likely due to network congestion and traffic prioritization.
- 📉 Speed drops immediately after exceeding a certain monthly traffic threshold.
- 📉 The restriction only applies to protocols specific to PCs (for example, torrents or game updates).
- 📉 At night (from 03:00 to 07:00) the distribution speed can be restored to full.
Errors in access point (APN) settings
One of the most common reasons for poor distribution is incorrect internet access point settings. In the operating system Android parameters APN (Access Point Name) determines how the device connects to the operator's gateways. If these settings use an outdated protocol or the wrong APN type, the phone may route traffic incorrectly when tethering is enabled.
By default, your phone is assigned an automatic profile that comes with your SIM card. However, it's not always optimized for tethering. It's recommended to manually check and, if necessary, create a new access point. Tele2 The default settings usually look a certain way, but sometimes you need to change the authentication type or protocol.
Pay special attention to the "APN Type" field. If only default, try adding them separated by commas dun (Dial-Up Networking). This setting informs the network that the device is being used for internet tethering, which in some cases helps avoid automatic blocking or redirects to pages asking to pay for the service.
It's also worth checking your IPv4/IPv6 settings. In some regions and on some towers Tele2 Pure IPv4 is more stable, while automatic selection (IPv4/IPv6) can cause routing conflicts when connecting external devices. Switching to IPv4-only often resolves the issue of frozen downloads.
| Parameter | Recommended value | Description |
|---|---|---|
| Name | Tele2 Internet | Custom profile name |
| APN | internet.tele2.ru | Primary gateway address |
| APN type | default,supl,dun | Critical for Wi-Fi distribution |
| Protocol | IPv4/IPv6 | It's better to test both options. |
The influence of frequency ranges and communication standards
The quality of the distribution directly depends on the frequency your smartphone is currently operating on. Network Tele2, like others, uses different frequency bands: 800 MHz (Band 20), 1800 MHz (Band 3), and 2600 MHz (Band 7). Low frequencies (800 MHz) penetrate walls better but have lower throughput, which is critical for distribution.
When you're in an area with poor reception, your phone may switch between 3G and 4G. In 3G mode, the download speed will always be unsatisfactory, regardless of your phone's settings. The problem is that the switching algorithms aren't always optimal: the phone may "catch" on a stable but slow 3G connection instead of the unstable but fast 4G.
To force switching to 4G (LTE)-only mode, you can use the engineering menu or special apps. However, be careful: forced LTE only This can lead to a complete loss of connection if there's no 4G signal at your location. This is especially true for trips out of town or in buildings with thick walls.
How to enter the Android engineering menu?
Enter the dialer code ##4636##In the menu that opens, select "About phone" and under "Set preferred network type," select LTE Only. Keep in mind that these settings may reset after a reboot.
High frequencies (2600 MHz) provide the fastest speeds but have a very limited range. If the indicator shows 4G but the speed is low, you may be at the edge of the high-speed band's coverage area. In this case, even slightly moving your phone closer to a window can make a significant difference.
Software conflicts and power saving settings
Modern smartphones are equipped with aggressive power-saving systems that can interfere with Wi-Fi tethering. When a phone is tethering, it simultaneously receives data over the mobile network and transmits it over Wi-Fi, creating a double load on the radio module and processor. The system may mistakenly detect this as an anomaly and begin throttling background processes.
This is especially common on shells. MIUI, EMUI And OneUIFeatures like "Smart Tethering" or "Data Saver" can block connections on connected devices if they detect suspicious or excessive traffic. It's important to check the battery settings for system services responsible for networking.
Third-party apps, such as VPN clients, antivirus software, or firewalls, can also cause this. If a VPN is enabled on the phone, it can redirect all traffic through a remote server, which creates significant latency and significantly reduces upload speeds. When a hotspot is enabled, the VPN on the phone itself should either be disabled or configured in split-tunneling mode.
- 🔋 Disable "Ultra Power Saving" mode before turning on distribution.
- 🔋 Check if there is a background activity restriction for Google or iOS system processes.
- 🔋 Temporarily disable your VPN and antivirus to check their impact on the channel.
Overheating is also worth mentioning. When actively broadcasting Wi-Fi, the phone heats up. If the temperature reaches a critical level, the processor throttles its frequencies (throttles), and the modem also reduces its transmit power, leading to a drop in speed and signal quality. Removing the case or using a cooler may unexpectedly improve the situation.
Tele2 tariff plans and hidden limits
The financial aspect of the issue cannot be ignored. Operator Tele2 Implements various monetization mechanisms for internet sharing. Even on plans labeled "unlimited," Wi-Fi sharing is often capped at a certain amount (e.g., 3, 5, or 10 GB per month). Once this limit is reached, the speed is throttled to a minimum or an additional fee is charged.
There are also options that allow you to legally unblock tethering. For example, the "Unlimited Apps" service may not apply to tethering. Users often forget that by updating apps in the background on their tablet, they're using up their tethering data plan, not their main unlimited data plan.
⚠️ Attention: The operator may use Deep Packet Inspection (DPI) methods to determine the type of traffic. Attempts to bypass the distribution block by changing the TTL may be considered a violation of the network terms of service, which may result in the complete blocking of the number.
It's also important to note that some corporate plans or older archived plans may have strict restrictions on the use of SIM cards in modems and phones for data sharing. If you use a SIM card that was previously in a router and have now moved it to a phone, the network may detect the device change (IMEI) and apply restrictions.
☑️ Check tariff restrictions
Diagnostics and solutions
If you encounter a problem, proceed by elimination. Start with a simple device reboot and balance check. Then move on to more complex network settings. A factory reset often helps, clearing accumulated configuration errors.
Try changing your network name (SSID) and password. Sometimes, your access point may have other devices ("neighbors") connected to it, consuming all the bandwidth. Change your password to a complex one and use encryption. WPA2-PSK or WPA3 are mandatory.
As a last resort, if software methods don't help, you can try flashing your phone or updating the base radio system. However, this requires a high level of expertise. A safer approach is to contact your carrier's support team and request an update to the network profile on the hardware side.
It's also helpful to test with a different SIM card (e.g., from a different carrier) on the same phone. If tethering works fine with the other SIM card, then the issue is definitely with the infrastructure or settings. Tele2, and not in the hardware of your smartphone.
Why does the download speed drop in the evening?
In the evening, the load on base stations increases. The operator prioritizes traffic, and dial-up connections often receive lower priority than mobile traffic. Furthermore, Fair Use Policy restrictions may be activated at this time.
Is it possible to bypass the distribution limit?
There are methods for changing the TTL, but they require root access or complex setup and may violate your contract with the operator. The official way is to enable the appropriate option in your personal account.
Does a case affect Wi-Fi speed?
Yes, metal or thick cases can shield your smartphone's antennas, especially if they're located around the perimeter of the case. To test this, remove the case and check the speed.
What should I do if the 4G light is on but the internet isn't working?
Try turning airplane mode on and off. If that doesn't help, check your APN settings. If that doesn't help, the tower may be undergoing maintenance or your account may be out of money.
How do I check who is connected to my Wi-Fi?
In your Android or iOS hotspot settings, there's a list of connected devices. If you see any unfamiliar devices there, change the password immediately and block access.
