“Connected except calls” on Xiaomi smartphones: reasons and fix

The message “Connected except calls” on the Xiaomi screen is one of the most annoying problems for smartphone owners of the brand. You see the icon of the mobile network, but you can’t call, send SMS or use the mobile Internet, and Wi-Fi and messengers (like WhatsApp or Telegram) work fine. What is the matter?

This error occurs due to malfunctions in the SIM- card, incorrect network settings or software conflicts in the MIUI. Most often, the problem occurs after a firmware update, a change of operator or physical damage to the card slot. In 80% of cases it can be eliminated without contacting the service center - just follow a few simple steps.

In this article, we will discuss 7 proven ways to fix the Connected Except Calls error on Xiaomi Redmi, POCO, Mi and other models, as well as explain why it occurs and how to prevent it from recurring.

1.What does the status "Connected except calls" mean?

The message “Connected except calls” (or “Only emergency calls” in the English version of MIUI) indicates that your smartphone is connected to the network of the operator, but can not use the basic functions:

  • 📞 Calls (outgoing and incoming)
  • 📩 SMS/MMS
  • 🌐 Mobile Internet (3G/4G/5G)

In doing so,

  • ✅ The network icon is displayed in the status bar
  • ✅ Wi-Fi and applications are working normally
  • ✅ Emergency numbers (112, 911, etc.) can only be called.

This error is not related to locking IMEI or hardware breakdowns (unless you drop your phone in water or damage the SIM- slot).

Reason.How it manifestsFrequency of occurrence
Failure of APN settingsThe Internet and calls don’t work at the same time.40%

Conflict after MIUI updateThe problem arose immediately after installing a new firmware20%
Operator restrictionsCalls are blocked due to non-payment or technical work10%
Hardware malfunctionsThe problem persists after all software fixes5%

The most common cause is the incorrect settings of the APN (access points), which can get lost after a system update, change of operator or manual editing, and the error is often caused by dual SIM- cards if one of them is inactive or blocked.

⚠️ Warning: If the problem occurs after a phone drop or moisture hits, do not attempt to fix it programmatically, this may be a sign of damage to the antenna module or contacts of the SIM- slot, in which case a diagnosis is required at the service center.

MTSmtsinternet.mts.rudefault,supl,mms
Beelinebeelineinternet.beeline.rudefault,supl,mms
MegaFonmegafoninternetdefault,supl,mms
Tele2.tele2internet.tele2.rudefault,supl,mms

FAQ: Frequent questions by error "Connected except calls"

🔹 Why After Updating MIUI The calls stopped working?
MIUI updates sometimes reset APN settings or conflict with the communication module. Try: Reset APN settings (section 4). Roll back firmware (section 7.2). Reset network settings (section 6.1). If nothing helps, wait for the next update - often Xiaomi fixes such bugs in new versions.
🔹 Can I make Wi-Fi calls if my mobile calls are not working?
Yes, if your carrier supports VoWiFi (voice calls over Wi-Fi). Activate the function: Settings → SIM- Cards and mobile networks → [Your SIM] → Wi-Fi call. Turn on the switch. Wait for 1-2 minutes - the Wi-Fi Calling icon should appear in the status bar. The service is available from MTS, Beeline, MegaFon and Tele2, but may require additional activation via your personal account.
🔹 Why does everything work on the second SIM- card, and the first card only “except calls”?
This is a typical problem of two-symbol Xiaomi: 📱 Slot conflict: one of the SIM-I've blocked the voice services for another card. 🔄 Network Priority: Priority can be set for the second SIM. Check in Settings → SIM-map → Priority SIM call-in. 🚫 Operator restrictions: some rates block calls when the second is active SIM. Check with the operator.
🔹 How to check if my phone is locked by a carrier?
If the operator has blocked voice services (for example, for non-payment), you will see: SMS from the operator with a notification of blocking; Inability to call even emergency numbers (except 112). In the personal account, the status of services will be marked as “Blocked”. Solution: replenish the account or contact the operator’s support.
🔹 Can a virus cause a Connected Except Calls error?
In theory, but very rarely, viruses don't block calls, but fake apps (like network accelerators or modified firmware) can. If you've installed software from unverified sources: Check your phone with an antivirus (Dr.Web, Kaspersky). Delete suspicious apps. Reset to factory settings (section 6.2).

💡

If you frequently experience network problems on Xiaomi, turn on the option “Disable Automatic Network Selection” in the developer settings. This will help avoid accidental switching to unstable base stations. To activate developer mode, tap 7 times on the build number in Settings → About phone.
