Missing IMEI on Android: Safe Recovery

If Android shows Unknown, Null, or a blank value for IMEI, the safe goal is to recover the identifier originally assigned to that phone. Do not create a replacement number, copy one from another device, or use an Internet tool that promises to write a new IMEI. Start by finding the original value, documenting the failure, and identifying whether the fault appeared after an update, a repair, water or impact damage, or an unofficial firmware flash.

Important: an IMEI is a device identifier used by mobile networks. Keep the full number private, and share it only with your carrier, manufacturer, seller, insurer, or an authorized repair provider when they need it.

Quick answer: recover the original IMEI safely

1. Use only the IMEI originally assigned to the device, never a generated, copied, or substituted number.
2. Record the model, serial number, baseband version, build number, and when the failure began before resetting or flashing anything.
3. Check the original box, SIM tray, purchase record, Settings, and Google Find Hub for the phone's assigned IMEI.
4. If the IMEI disappeared after flashing, stop trying unrelated firmware. Obtain the exact official package for the finished model, region, storage variant, and board revision.
5. If both IMEI and baseband information are missing, or the phone was dropped, wet, or repaired, use the manufacturer's support channel or an authorized service center.

A restart, SIM check, and official system update are reasonable first steps. A factory reset erases user data and is not a direct IMEI repair, so do not use it as a blind first attempt.

What an IMEI is and why the original matters

IMEI stands for International Mobile Equipment Identity. GSMA documentation describes it as the unique network identifier allocated to a mobile device by its manufacturer. A mobile network receives the identifier when the device connects and can use it for device recognition and block-list checks.

The IMEI identifies the mobile equipment, while the SIM or eSIM identifies the subscriber account. Replacing a SIM can fix a subscription or contact problem, but it does not assign a new legitimate IMEI to the phone. Likewise, an Android ID, Wi-Fi MAC address, serial number, EID, ICCID, and phone number are different identifiers.

Some phones expose two IMEIs because they support two simultaneous mobile subscriptions. Google documents IMEI 1 and IMEI 2 for supported dual-SIM Pixel phones. Do not assume that the two values should match.

Find the original IMEI before troubleshooting

Use more than one source and compare the model details. The following methods read or recover the assigned identifier; they do not change it:

• Android Settings: open Settings, then About phone. The exact menu varies by manufacturer and Android version.
• Phone dialer: enter *#06#. Samsung notes that this works when supported by the carrier and device software.
• Original packaging: look for the label with the model, serial number, and one or two IMEIs.
• SIM tray or device label: some manufacturers print the identifier on the tray, rear label, or beneath a removable battery. Do not open a sealed phone just to search for it.
• Google Find Hub: Google says a linked Android device's IMEI may be visible in Find Hub settings even when the phone is not in your hand.
• Seller or carrier records: a receipt, contract, account page, or repair record may contain the original value.

If the number on the box or tray does not match the device model or purchase record, pause. Packaging can be swapped, and used phones may have incomplete histories. Ask the seller, carrier, or manufacturer to verify the device rather than writing either number into Android.

Confirm what is actually missing

“No IMEI” is often used for several different failures. Capture screenshots or written notes for each field before taking action:

What you see	What it suggests	Next check
IMEI is visible, but there is no mobile service	The identifier is present; the issue may involve the SIM, eSIM, carrier account, coverage, network settings, or radio	Check SIM status, carrier status, airplane mode, and another known-good SIM if supported
Dialer shows Unknown or Null, but baseband version is present	Android can see part of the modem stack, but device-specific radio data or firmware may be unavailable	Record the build and ask the manufacturer for the exact recovery path
IMEI and baseband version are both Unknown	The modem firmware may not be loading, or the phone may have a board-level fault	Stop random flashing and move to model-specific support or hardware diagnosis
Only IMEI 2 is absent	The second slot or eSIM path may be disabled, unsupported in the current configuration, or affected separately	Verify the model's dual-SIM specification and current SIM configuration
IMEI is present, but the carrier rejects the device	The device may be blocked, unsupported, locked, or not provisioned for that network	Contact the carrier with proof of ownership and the original IMEI

Find the baseband field in Settings under About phone, Android version, or Status, depending on the device. A missing baseband is an important symptom, not a prompt to download a random modem image.

Back up data and record device facts

Before an update, reset, recovery operation, or service visit, preserve what you can. Google recommends backing up before a factory reset or repair because some service work requires storage replacement or erasure.

• Back up photos, messages, contacts, authenticator recovery codes, and app data that your backup method supports.
• Record the brand, exact model code, region, storage capacity, serial number, Android version, security update, build number, and baseband version.
• Save the original firmware filename and source if the problem began after an update or flash.
• Write down the last time mobile service worked and any physical event such as a fall, liquid exposure, battery repair, or mainboard replacement.
• Remove the SIM before sending the phone to a repair provider. Use Repair Mode or Maintenance Mode when the manufacturer supports it.

Do not post screenshots containing the full IMEI in forums or public issue trackers. Redact most digits while leaving enough context to distinguish IMEI 1 from IMEI 2.

Try the safe first steps

1. Restart the phone once. A temporary radio service failure can make status fields unavailable until the system and modem restart.
2. Toggle airplane mode off and on. Then wait for the phone to register with the network.
3. Power off and reseat the physical SIM. Inspect the tray for damage. Do not force an adapter or cut SIM into the slot.
4. Check for an official system update. Use the built-in updater and install only the package offered for the exact device.
5. Compare another known-good SIM when practical. This can separate a carrier or SIM failure from a device failure, although it cannot repair a missing IMEI.
6. Review the carrier account. Confirm that service is active and that the original IMEI is not blocked or unsupported.

If the phone started showing Unknown immediately after an update, collect the new build and baseband versions before doing anything else. If the phone was physically damaged, skip repeated software changes and request a hardware inspection.

If the IMEI disappeared after flashing

Stop cycling through firmware packages. The chipset name alone is not enough to identify compatible radio software. Two devices using the same MediaTek, Qualcomm, Unisoc, Exynos, or other platform can have different modem configuration, storage layouts, regional builds, and board revisions.

1. Identify the finished-device model, not only the processor.
2. Confirm the country or carrier variant, storage capacity, board revision, and previous build if known.
3. Return to the manufacturer's signed recovery package and documented tool for that exact model.
4. Do not select format, erase-all, modem, NVRAM, NV data, persist, or calibration operations unless the official service procedure for that exact device explicitly requires them.
5. If the official recovery completes but the original IMEI remains unavailable, stop and contact the manufacturer or an authorized repair center with proof of ownership.

A successful Android boot does not prove that the modem firmware and device-specific radio data are intact. Repeated writes can remove useful evidence and make professional recovery harder.

What Unknown baseband means

The baseband entry reports the modem firmware version that Android can read. If it is Unknown, the radio processor or its firmware may not be initializing. Causes can include an incompatible build, damaged modem partitions, a failing storage device, a loose or damaged board connection after repair, liquid damage, or a mainboard fault.

This symptom needs model-specific diagnosis. An authorized technician can compare the software branch, run manufacturer diagnostics, inspect the board, and restore supported factory software. Copying an NVRAM file or calibration data from another phone is not a safe substitute because those files can contain identifiers and radio calibration unique to that device.

Will a factory reset restore IMEI?

Usually, a factory reset should be treated as a user-data and settings reset, not as an IMEI repair. Google states that a factory reset erases data from the phone, removes apps and their data, and requires the account credentials needed to set the device up again. It recommends trying other troubleshooting first and using the manufacturer's device-specific instructions.

A reset may clear a software setting that interferes with network service, but it cannot be relied on to rebuild missing modem firmware, repair storage, reconnect damaged hardware, or legitimately assign an identifier. Back up first. Reset only when the manufacturer or repair workflow calls for it and you know the Google Account password and screen lock credentials.

Can IMEI be restored without root?

Yes, legitimate recovery should not require rooting the phone. The normal paths are an official over-the-air update, the manufacturer's signed recovery tool, an authorized service procedure, or board replacement and provisioning performed through approved service channels.

Root access does not prove that a file or command is correct. It removes security boundaries and can make it easier to overwrite modem data, break verified boot, expose personal information, or complicate warranty and service diagnostics. Avoid tutorials that require root only to paste a file into a protected radio directory.

Use the manufacturer's repair path

• Google Pixel: Google provides a repair flow, authorized repair partners, Repair Mode for eligible devices, and official software repair tools. Google recommends backing up and removing the SIM before service.
• Samsung Galaxy: use Samsung Support to identify the exact model and service options. Samsung's official IMEI guide lists Settings, the original box, carrier records, Samsung Members, and *#06# as ways to find the assigned number.
• itel, including itel A52: verify the original number from the box, tray, purchase record, or available settings. Use only firmware for the exact A52 variant. itel's official after-sales page directs customers to Carlcare service centers by country and city.
• Other Android brands: start at the manufacturer's regional support site. Provide the model, serial number, original IMEI, proof of purchase, current build, baseband status, and a concise timeline.

If the manufacturer no longer supports the model, choose a reputable repair shop that can explain its diagnostic process, protect your data, and return the device without changing its assigned identity.

Dual-SIM phones, eSIM, and two IMEIs

A dual-SIM phone may have IMEI 1 and IMEI 2. The second value can correspond to a second physical slot, eSIM capability, or the device's dual-SIM configuration. Google notes that supported Pixel phones can show one IMEI for each SIM path.

Do not copy IMEI 1 into the second field. First confirm that the exact model supports two active subscriptions and that the second SIM or eSIM feature is enabled. If one value remains missing after the official software and configuration checks, ask the manufacturer to diagnose that specific SIM path.

Repair checklist

Evidence to collect	Why it matters	Safe action
Original IMEI from box, tray, account, or receipt	Establishes the device identity without writing anything	Keep a private photo or record and provide it to authorized support
Exact model, region, storage, and board revision	Separates similar devices that use different radio software	Match only official packages for that variant
Build number and baseband version	Shows whether Android and the modem report compatible software	Compare with manufacturer support information
Time and event when service failed	Distinguishes update, flash, repair, impact, liquid, and carrier causes	Give the timeline to support or the technician
Carrier response and SIM test	Separates device identity from subscription or block-list issues	Resolve account or provisioning issues with the carrier
Backup status	Recovery or service may erase storage	Complete and verify a backup before destructive work

Methods to avoid

• IMEI generators, calculators, cloning services, or numbers copied from another phone.
• Secret engineering-menu write commands or “UserBuild” bypasses from old tutorials.
• Unknown Windows executables, batch files, cracked service tools, or archives from abandoned file-sharing links.
• NVRAM, NV data, QCN, EFS, persist, or calibration files taken from another device.
• Format-all or erase-all operations used as generic troubleshooting.
• Firmware chosen only by processor name or a similar-looking model.

These methods can overwrite unique radio data, expose the computer to malware, leave the device unable to connect, or hide the original cause. Preserve the device's assigned identity and use a documented repair path.

Frequently asked questions

How can I recover an IMEI number without root?

Find the original number on the box, tray, purchase record, carrier account, Settings, or Google Find Hub. For recovery, use official updates, the manufacturer's signed repair tool, or an authorized service provider. Root is not required for a legitimate manufacturer repair.

Why did IMEI disappear after a firmware update?

The installed package may not match the exact device variant, or the modem software and device-specific radio data may not be loading. Record the build and baseband versions, stop random flashing, and use the exact official recovery package or service procedure.

Does a factory reset restore IMEI?

Do not count on it. A factory reset erases user data and settings. It is not a direct repair for missing modem firmware, damaged radio data, or hardware failure.

What if both IMEI and baseband are Unknown?

That combination points to a modem initialization problem that may involve incompatible software, damaged storage, or hardware. Stop writing firmware and request model-specific diagnosis.

Where can I find the original IMEI?

Check Settings, *#06#, the original box, the SIM tray or device label, Google Find Hub, your carrier account, purchase contract, receipt, and previous repair records.

Can one phone have two IMEIs?

Yes. Dual-SIM and eSIM-capable phones can have one IMEI for each supported mobile-radio path. Do not expect the two numbers to be identical.

How do I restore IMEI on an itel A52?

Confirm the exact A52 variant and original number from the label, box, purchase record, or settings. Do not use another phone's number or a generic MediaTek package. Use the exact official firmware path for that variant or select your country and city on itel's official Carlcare service-center page.
