Xiaomi smartphone owners often face a situation when, after installation, SIM-Maps or changing the region of access to the network through mobile data becomes impossible. Phoenix is no exception, and the correct operation of tariffs often requires manual registration of access point parameters. Automatic settings may not come or be incompatible with the current shell version MIUI or hyperos.
Competent network configuration provides stable connection, high download speed and no breaks when switching between 3G and 4G standards. In this article, we will discuss in detail the process of creating an APN profile, check the modem settings and eliminate typical errors that prevent the full use of operator services.
Often the problem is not the lack of money in your account, but the wrong network mode or system services failure. Understanding how the data protocol works on your device will help quickly diagnose a malfunction. We will look at all the nuances, from entering letter marks to resetting network parameters to factory values.
Device preparation and verification SIM-map
Before you go to the complicated menu settings, you need to make sure that the communication components are physically healthy. SIM-The Phoenix card is installed in the correct slot if your smartphone supports two cards. Often users inadvertently choose a slot where data transfer is limited or lock is blocked.
Check your account balance and make sure that the mobile Internet service is activated on the number. Even if there is a positive balance, access can be blocked due to the end of the traffic pack or a change in the tariff plan. USSD-team to check service status.
⚠️ Attention: Make sure that SIM-The card is not physically damaged and is not too old. 2G They may not work properly on networks. 4G/LTE, Requiring a replacement from the operator's office.
Remove the tray for SIM-You can wipe the contacts with a soft dry cloth, and contact oxidation is a common cause of intermittent connection. After you install the card, restart your Xiaomi smartphone so that the system is re-registered on the operator's network.
Make sure that the settings are enabled data transfer. To do this, lower the notification curtain and activate the "Mobile Internet" option or go to Settings → SIM-maps and mobile networks. Here the "Use mobile data" switch for the selected data should be on. SIM-map.
Manually configuring the APN access point
The most effective way to communicate is to manually create a new access point. SMS, Often contain errors or outdated gateway addresses. You need to go to the settings menu by selecting the Settings path. → SIM-maps and mobile networks → (Yours. SIM Phoenix) → Access points (APN).
In the list that opens, click the New Access Point button or the + icon in the upper right corner of the screen. It is important to enter all the parameters carefully, since even one extra letter or space can lead to an error in authorization in the operator's network. Below is a table with the current parameters for the Phoenix operator.
| Parameter | Meaning | Note |
|---|---|---|
| Name (Name) | Fenix Internet | arbitrary name |
| Access Point (APN) | internet.fenix | The register is not important. |
| User name | (leave empty) | Don't fill in |
| Password. | (leave empty) | Don't fill in |
| Type APN | default,supl | Comma separator |
Once you have entered, be sure to click the menu (three dots) and select Save. Then go back to the access point list and activate the profile you just created by putting a marker next to it. Rebooting your phone after this step is optional, but desirable for the changes to be applied.
⚠️ Attention: If the field "Type" APN» It contains other default values, replace them with default, supl or just default.
Some versions of MIUI may require a protocol setting. In the advanced access point settings, look for "APN Protocol" and select IPv4/IPv6, which will ensure compatibility with all modern carrier servers.
☑️ Checking settings APN
Configure the preferred type of network
The correct operation of the Internet depends not only on the access point, but also on the chosen mode of operation of the radio module. Xiaomi smartphones allow you to flexibly manage network priorities. → SIM-maps and mobile networks → Preferred type of network.
For maximum speed, it is recommended to choose 4G or 5G/4G/3G/2G (auto). If 4G coverage is unstable in your region, the phone will constantly switch between standards, causing connection breaks, in which case it is better to force "3G only" to test the tab.
Sometimes switching network mode to reset registration at the base station helps: select 2G only, wait 10 seconds, then return the value of 4G Preferably.This method often solves the problem when the 4G icon is on, but the pages are not loading.
💡
If the internet is slow, try the access point settings (APN) change MCC and MNC Your region values, although they are usually automatically substituted with SIM-map.
Resetting network and modem settings
If manually configuring APN didn't help, there may have been software errors in the system. Network resets will return Wi-Fi, Bluetooth and mobile settings to factory values.This action won't delete your personal files, but saved Wi-Fi passwords will be lost.
To perform the reset, go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. Click Reset button at the bottom of the screen and confirm the action with an unlock code or fingerprint.
Once the device is restarted, re-enter the access point settings described in the second section of the article, often addressing issues that have arisen after the MIUI firmware update, when old configuration files conflict with new ones.
⚠️ Before resetting, make sure you know the passwords from important Wi-Fi networks, as it will not be possible to recover them from the phone’s memory after this procedure.
Diagnostics through the Engineering Menu
For advanced users, modem status check is available via the hidden engineering menu. In the Phone app, dial the combination ##4636##. If the menu opens, select Phone Information.
In the "Tune your preferred network type" section, you can see the current status of the connection, and here you can see the "Run a Ping Test" button, which checks the availability of the Google server, and if the ping does not pass, the problem is on the operator or antenna side.
You can also force the radio interface to switch from this menu, such as selecting LTE Only. Using LTE Only mode can make it impossible to make voice calls unless VoLTE technology is activated. Use this mode only to test download speeds.
The way to the test: Phone menu → Phone information → Run a ping testIf the engineering menu displays a status of "Disable" or "No Service" at the full signal scale, this may indicate a software failure of the radio module, in which case only a complete data reset or flashing the device helps.
Frequent problems and their solution
One of the common problems on Xiaomi is aggressive energy saving, which can put the communication module to sleep. Go to Settings → Battery and performance and find the app responsible for the network (usually “Settings” or system process). Set the “No Limits” mode.
It's also worth checking if the Data Savings mode is enabled, which blocks background application activity and can limit browser speed. → SIM-maps and mobile networks → Saving traffic.
If you use a VPN or proxy server, try disabling them.Incorrect proxy settings at the APN hotspot (Proxy and Port fields) are a common reason for the lack of internet. Make sure these fields are empty if the operator does not provide special data.
What do you do if nothing helps?
💡
In 90% of cases, the problem is solved by correctly entering the APN parameters and restarting the device.
