Xiaomi Emergency Calls Only on Verizon in Detroit
Xiaomi Emergency Calls Only on Verizon in Detroit: 2026 Troubleshooting Guide
If your Xiaomi, Redmi, or POCO phone shows "Emergency Calls Only" or "Not Registered on Network" while using Verizon in Detroit, Dearborn, or elsewhere in Michigan, the problem is usually related to device compatibility, network registration, SIM/account provisioning, or VoLTE/IMS configuration.
Imported Xiaomi phones require extra attention on Verizon because Verizon requires a BYOD device to be unlocked and compatible with both its network hardware and software requirements. Verizon also provides an IMEI-based compatibility check before activation.
Works For
- ✔ Xiaomi phones
- ✔ Redmi phones
- ✔ POCO phones
- ✔ HyperOS
- ✔ MIUI
- ✔ Verizon Wireless
- ✔ Visible on the Verizon network
- ✔ Total by Verizon
- ✔ US Mobile using Verizon network service
Important: The exact compatibility of a Xiaomi phone depends on the specific model, regional hardware variant, software configuration, IMEI and carrier provisioning. A Xiaomi phone working on another U.S. carrier does not automatically mean it will work on Verizon.
Before You Start – Quick Checks
- ✔ Restart the phone to clear temporary network-registration problems.
- ✔ Toggle Airplane Mode on for about 30 seconds, then turn it off.
- ✔ Reseat the physical SIM if you use one.
- ✔ Check that your Verizon line is active and there is no account or service issue.
- ✔ Check Verizon's current network status if the problem occurs only in one location.
- ✔ Check the Xiaomi's IMEI compatibility before spending time changing advanced settings.
If these checks do not solve the problem, continue below.

Quick Fix – Xiaomi Emergency Calls Only on Verizon
- ✔ Check Verizon compatibility first. Use Verizon's BYOD checker with the phone's IMEI. If Verizon reports that the device is incompatible, changing APN, resetting network settings, or switching network modes will not make the device compatible.
- ✔ Test the SIM in another compatible phone. If the SIM works there, the problem is more likely related to the Xiaomi, its hardware variant, software configuration, or device provisioning.
- ✔ Run a manual network scan. If the Xiaomi can see Verizon but cannot register, the problem is different from a phone that cannot detect the Verizon network at all.
- ✔ Use the normal automatic network mode. Keep 5G/LTE automatic or the equivalent default setting. If registration behaves differently on LTE, temporarily test LTE to isolate a 5G-related problem.
- ✔ Check VoLTE and IMS. If the phone can connect to the network but voice service does not work, VoLTE/IMS and carrier provisioning become important.
- ✔ Contact Verizon or your MVNO if the device passes compatibility checks but still cannot register.
Important: An IMEI compatibility result is more useful than guessing based only on the Xiaomi model name. Xiaomi models are sold in different regional hardware variants, so the exact variant matters.
Understanding "Emergency Calls Only" on Verizon
When a Xiaomi shows "Emergency Calls Only" or "Not Registered on Network", the phone may be able to detect a cellular network but is not successfully obtaining normal service on the network.
The message itself does not identify one specific fault. Several different problems can produce similar symptoms.
On Xiaomi phones using Verizon, investigate these areas:
- Device compatibility: Verizon requires compatible hardware and software for BYOD service.
- Device lock status: A phone locked to another carrier cannot normally be activated as a Verizon BYOD device.
- Regional hardware variant: Different Xiaomi variants can support different cellular bands.
- SIM or eSIM problems: The SIM may be damaged, incompatible, inactive, or incorrectly provisioned.
- Network selection: The phone may not be selecting or registering with the expected network.
- VoLTE/IMS problems: The phone may have cellular connectivity but fail to establish the services required for voice.
- Carrier provisioning: Verizon or an MVNO may need to correct the line or device configuration.
- ROM/firmware configuration: Software can affect carrier profiles and IMS behavior.
Do not assume that "Emergency Calls Only" automatically means a bad SIM. The correct diagnosis depends on what happens during the tests below.
Core Diagnostic Logic
Use the following sequence instead of randomly changing settings:
- 1. Is the SIM detected?
- ↓
- NO → Check SIM, SIM slot, eSIM activation, and hardware.
- YES → Continue.
- ↓
- 2. Does the same SIM work in another Verizon-compatible phone?
- ↓
- NO → Investigate SIM, account, or carrier provisioning.
- YES → The Xiaomi becomes the main suspect.
- ↓
- 3. Does the Xiaomi see Verizon during a manual network scan?
- ↓
- NO → Investigate coverage, hardware variant, supported bands, SIM and hardware.
- YES → Continue.
- ↓
- 4. Can the phone register on Verizon?
- ↓
- NO → Investigate compatibility, provisioning, SIM, network mode and device software.
- YES → Continue.
- ↓
- 5. Does voice service work?
- ↓
- NO → Investigate VoLTE, IMS and carrier provisioning.
- YES → If only mobile data fails, investigate APN.
Symptom Check – Quick Reference
| Symptom | Possible Cause | Next Test |
|---|---|---|
| "Emergency Calls Only" | Registration, compatibility, SIM, provisioning or VoLTE/IMS problem | Check IMEI, SIM and network registration |
| "Not Registered on Network" | Device cannot complete network registration | Check compatibility, manual network selection and provisioning |
| SIM is detected but Verizon cannot be selected | Coverage, supported-band, hardware, SIM or compatibility issue | Run a manual network scan and test the SIM elsewhere |
| Verizon appears during scanning but registration fails | Compatibility, provisioning, SIM or software configuration | Check IMEI compatibility and carrier provisioning |
| SIM works in another phone | Problem is more likely related to the Xiaomi | Check IMEI, model variant, software and network settings |
| SIM fails in another phone too | SIM, account or carrier issue | Contact Verizon or the MVNO |
| Calls work but mobile data does not | APN or mobile-data configuration | Check APN settings |
| Problem occurs only in one location | Coverage, local network issue or tower problem | Test at another location and check network status |
Step-by-Step Fixes
Step 1: Check Verizon Device Compatibility
Why this matters: Verizon's BYOD program requires a device to be unlocked and compatible with the Verizon network. Verizon uses the device ID/IMEI to perform its compatibility check.
Find your IMEI:
- Open the Phone app.
- Dial *#06#.
- Record the IMEI shown for the SIM you are testing.
You can also find the IMEI under Settings → About phone on many Xiaomi devices.
Check Verizon compatibility:
- Open Verizon's official BYOD compatibility checker.
- Enter the 15-digit IMEI.
- Check the result.
If Verizon says the device is compatible: Continue to Step 2.
If Verizon says the device is incompatible: Treat compatibility as the primary problem. Do not expect an APN change or network reset to overcome a hardware/software compatibility restriction.
Important: Do not assume that all Xiaomi 13, 14, 15, Redmi Note, or POCO variants have identical network support. The exact regional variant and IMEI matter.
Also check whether the phone is carrier-unlocked. Verizon states that BYOD devices must be unlocked before they can be brought to the network.
Step 2: Test the SIM in Another Verizon-Compatible Phone
Why this matters: This is one of the fastest ways to separate a carrier/SIM problem from a Xiaomi problem.
- Turn off the Xiaomi.
- Remove the Verizon SIM if it is a physical SIM.
- Insert the SIM into a known compatible, unlocked phone.
- Wait for the phone to connect to Verizon.
- Test calls, SMS and mobile data.
If the SIM works normally: Your line is probably functional, so focus on the Xiaomi's compatibility, hardware variant, software or registration behavior.
If the SIM does not work: The problem may be the SIM, account, activation or carrier provisioning. Contact Verizon or your MVNO before changing advanced Xiaomi settings.
When this won't help: If you do not have access to another compatible phone, continue with the remaining tests.
Step 3: Check Whether the Xiaomi Can See Verizon
Why this matters: A manual network scan tells you whether the phone can detect networks in its current location. It does not prove that the phone is approved or capable of completing registration.
- Open Settings.
- Open SIM cards & mobile networks or the equivalent mobile-network menu.
- Select the Verizon SIM.
- Open Network operators or Choose network.
- Turn off Choose automatically.
- Wait for the network scan to finish.
If Verizon appears: The phone can detect a Verizon network in that location. However, detection does not guarantee successful registration. Continue to Step 4.
If Verizon does not appear: Check your location, SIM, hardware variant and supported bands. Also test the phone in another location before concluding that the device is incompatible.
Do not repeatedly force manual registration. Manual selection is primarily a diagnostic test. After testing, return to automatic network selection unless you have a specific reason to keep manual selection enabled.
Step 4: Check Preferred Network Type
Why this matters: An unusual or manually restricted network mode can prevent a phone from using the network normally.
- Open Settings → SIM cards & mobile networks.
- Select the Verizon SIM.
- Open Preferred network type.
- Use the normal automatic 5G/LTE mode offered by your Xiaomi.
- Restart the phone and test again.
If the phone behaves differently when using 5G versus LTE, temporarily test LTE as a diagnostic step.
Do not use 5G-only as a general fix. It can make troubleshooting harder because the phone may lose access to other available radio technologies.
When this won't help: If the phone still cannot register after using the normal network mode, continue to Step 5.
Step 5: Check VoLTE and IMS
Why this matters: Cellular network registration and IMS registration are not the same thing. A phone can detect a network and still have problems with the IMS services used for voice.
Enable VoLTE if the option is available:
- Open Settings → SIM cards & mobile networks.
- Select your Verizon SIM.
- Look for Use VoLTE, VoLTE calls or 4G Calling.
- Enable the option if it is available.
- Restart the phone.
- Test a normal voice call.
Check IMS status:
- Open the Phone app.
- Try dialing *#*#4636#*#*.
- Open Phone information if the diagnostic menu is available.
- Look for IMS-related information.
Important: The diagnostic code does not work on every Xiaomi model or software version. If nothing happens, that does not by itself prove that IMS is broken.
If IMS is unavailable or shows an unregistered state while the phone is otherwise connected, carrier provisioning or Xiaomi firmware/carrier configuration may be involved.
Step 6: Check SIM and Carrier Provisioning
Why this matters: A compatible phone can still fail to obtain service if the line, SIM/eSIM or device information is not correctly provisioned.
If you use Verizon directly:
- Check your account status.
- Confirm that the line is active.
- Ask Verizon to verify the device and line provisioning.
- Provide the IMEI if support requests it.
- If voice service is the problem, ask whether the required voice/VoLTE provisioning is correctly configured.
If you use an MVNO:
- Contact the carrier that actually manages your line.
- Ask them to verify the SIM/eSIM activation.
- Ask them to verify that the correct device information is attached to the line.
- Do not assume that Verizon support can fix provisioning for an MVNO account.
When this won't help: If the carrier confirms that the line and provisioning are correct, continue to Step 7.
Step 7: Reset Network Settings
Why this matters: A network reset can remove corrupted Wi-Fi, Bluetooth, mobile-network and related configuration without performing a full factory reset.
On Xiaomi devices, the exact menu name varies by HyperOS/MIUI version.
Look under areas such as:
- Settings → Connection & sharing
- Settings → More connectivity options
- Settings → Additional settings
Look for an option similar to:
Reset Wi-Fi, mobile networks and Bluetooth
- Open the network-reset option.
- Confirm the reset.
- Restart the phone.
- Re-enable the required mobile-network settings.
- Test Verizon again.
Important: A network reset can remove saved Wi-Fi networks and Bluetooth pairings. It does not change the phone's IMEI, cellular bands or Verizon compatibility status.
When this won't help: If the IMEI is incompatible or the hardware lacks required network support, a network reset cannot solve the underlying limitation.
Step 8: Check ROM and Firmware
Why this matters: Xiaomi software variants can contain different carrier configurations and modem/IMS behavior.
| Software Type | What It Can Affect |
|---|---|
| Global ROM | May contain carrier configurations intended for international/global markets. |
| EEA ROM | Can have different regional configuration and software behavior. |
| China ROM | May have different carrier and IMS configuration from global software. |
| Custom ROM | Carrier and IMS behavior depends on the ROM, modem firmware and device configuration. |
Critical distinction: Changing the ROM cannot add a cellular band that the physical hardware does not support.
For example, if a particular Xiaomi hardware variant does not support a band required in the area where you are using it, installing a different ROM will not add that radio capability.
On the other hand, firmware and carrier configuration can affect IMS, VoLTE and network behavior. Therefore, ROM is worth investigating after IMEI compatibility, SIM testing and basic network diagnostics.
Do not flash a different ROM just because the phone says "Emergency Calls Only." First determine whether the phone is actually compatible with Verizon.
If you are already using a Global ROM and Verizon's compatibility checker accepts the device, focus first on SIM, provisioning, network registration and IMS rather than immediately changing firmware.
Advanced: If Calls Work but Data Fails (APN)
Check APN Settings Only When Voice Service Works
Why this matters: APN settings control mobile-data connectivity. If the phone can make calls and send SMS but mobile data does not work, APN configuration becomes a reasonable troubleshooting target.
If the phone says "Emergency Calls Only", APN is not the first thing you should troubleshoot.
- Open Settings → SIM cards & mobile networks.
- Select your Verizon SIM.
- Open Access Point Names.
- Check whether the carrier has automatically supplied an APN.
- If data still does not work, compare the APN with the current settings recommended by your carrier.
Do not blindly copy APN values from another website. Verizon and its MVNOs can use different configurations, and APN requirements can change.
If calls, SMS and signal are working normally but data is not, use the APN configuration supplied by your specific carrier rather than assuming that a generic Verizon APN applies to every MVNO.
Key rule: If the phone cannot register on the network at all, fixing the APN will not solve "Emergency Calls Only."
Final Verdict
If your Xiaomi shows "Emergency Calls Only" or "Not Registered on Network" on Verizon, do not start by changing random APN values or flashing a new ROM.
Use this order instead:
- Check Verizon compatibility using the IMEI.
- Confirm the phone is unlocked.
- Test the SIM in another compatible phone.
- Check whether the Xiaomi can see Verizon during a manual scan.
- Use the normal automatic network mode and test LTE if necessary.
- Check VoLTE and IMS if voice service is the problem.
- Verify SIM, account and carrier provisioning.
- Reset network settings.
- Investigate ROM/firmware only after the basic compatibility checks.
The most important distinction is this:
Can the phone detect Verizon? This is a radio/network-visibility question.
Can the phone register on Verizon? This involves compatibility, SIM, provisioning and network configuration.
Can the phone use voice service? This can involve VoLTE/IMS and carrier provisioning.
Can the phone use mobile data? If registration and voice work, APN becomes relevant.
That distinction prevents you from applying the wrong fix to the wrong problem.
Detroit-specific note: If the same Xiaomi and SIM work elsewhere but fail only at a particular location in Detroit or Dearborn, investigate local coverage or a temporary network issue before changing the phone's firmware or configuration.

Frequently Asked Questions
Can Xiaomi phones work on Verizon?
Some Xiaomi phones may work on Verizon, but compatibility must be checked for the specific device. Verizon requires BYOD devices to be unlocked and compatible with its network hardware and software requirements. The safest first step is to check the phone's IMEI using Verizon's compatibility checker.
Why does my Xiaomi show "Emergency Calls Only" on Verizon?
The message can have several causes, including device compatibility, SIM or account problems, unsuccessful network registration, regional hardware differences, carrier provisioning, or VoLTE/IMS problems. The message alone does not identify the exact cause.
Does Verizon use an IMEI compatibility check?
Yes. Verizon's BYOD process uses the device ID/IMEI to check whether a device is compatible with the Verizon network. Verizon also requires the device to be unlocked for BYOD.
What should I check first if my Xiaomi cannot register on Verizon?
Start with the IMEI compatibility check, then test the Verizon SIM in another compatible phone. These two tests quickly separate many device-related problems from SIM or carrier problems.
Does seeing Verizon in a manual network scan mean my Xiaomi is compatible?
No. Seeing Verizon during a network scan only shows that the phone can detect a Verizon network at that location. It does not prove that the device is eligible for Verizon service or that it can successfully register.
Does my Xiaomi need Band 13 for Verizon?
Band support matters, but you should not determine compatibility from Band 13 alone. Verizon uses multiple frequency bands, and Xiaomi devices are sold in different regional hardware variants. Check the exact model and variant rather than assuming that every Xiaomi phone has the same bands.
Can changing the ROM fix Emergency Calls Only?
Sometimes software or carrier configuration can affect network and IMS behavior, but changing the ROM cannot add missing cellular hardware capabilities or override Verizon's compatibility requirements. Check IMEI compatibility and the physical hardware first.
Can a China ROM Xiaomi work on Verizon?
There is no reliable yes-or-no answer based on the ROM name alone. The exact hardware variant, supported bands, IMEI compatibility, firmware and carrier configuration all matter. A China ROM should not automatically be treated as proof that the phone is incompatible, but it can be relevant when investigating carrier or IMS behavior.
Is T-Mobile better than Verizon for Xiaomi phones?
There is no universal answer for every Xiaomi model. Imported Xiaomi devices can have different levels of compatibility across U.S. carriers. The important comparison is the exact Xiaomi model and regional variant against the carrier's current compatibility and network requirements.
Can a factory reset fix Verizon registration problems?
A factory reset is rarely the correct first solution. It cannot change the phone's IMEI, add missing cellular bands, or make an incompatible device compatible with Verizon. Try the diagnostic steps above first.
How do I check which Xiaomi model I have?
Open Settings → About phone and record the model name and model number. The model number is particularly important because different regional variants can have different cellular hardware.
Why did my Xiaomi lose Verizon service after a HyperOS update?
A software update can change network, modem or carrier configuration behavior. Before changing the ROM, restart the phone, reset network settings, check the preferred network mode, verify the IMEI compatibility and confirm that the carrier has correctly provisioned the line.
Should I change the APN when my Xiaomi says Emergency Calls Only?
No. APN settings control mobile data and are not the correct first troubleshooting step for a phone that cannot register on the network. Investigate compatibility, SIM, registration and carrier provisioning first.
