In the early 2000s, Nokia feature phones (like the Nokia 3310, 3510, 6210, etc.) ran on older chipsets (e.g., DCT3, DCT4). These phones had service codes and flashing tools that could rewrite the IMEI. Technicians used specialized hardware like:
With these, one could change the IMEI using software commands. Some users shared codes like *#7328748# or *#7465625# (network lock menus), but these never directly changed the IMEI. They were for network unlock.
The truth: There has never been a universal "secret code" you type into the dialer to change IMEI. Any website claiming *#*#3646633#*#* (MTK engineer mode) or *#301# works for Nokia is lying. Those codes are for MediaTek chips on Chinese brands—not Nokia.
If your Nokia (e.g., Nokia 5.3, Nokia G20, Nokia X10) shows “No Service” and *#06# returns “IMEI: 0” or “Invalid,” try this legal DIY fix:
Stop searching for “All Nokia Imei Change Code.” Instead, follow this flowchart of legitimate actions: All Nokia Imei Change Code
If IMEI is blacklisted:
→ Contact the seller or previous owner. Only they can request removal from the blacklist.
If IMEI is 0 or invalid after flashing:
→ Reflash the stock ROM using Nokia’s official tool (OST LA). Do not use unofficial “patch” files.
If network locked:
→ Request unlock code from your carrier or use a reputable code service.
If phone is stolen (your own):
→ Register the IMEI with police and your carrier to blacklist it. You don’t want anyone else changing it! In the early 2000s, Nokia feature phones (like
If you accidentally bought a stolen phone:
→ Return it. You have no legal recourse to “fix” the IMEI.
Before you go further, understand the law:
| Country | Penalty for IMEI Alteration | |---------|-----------------------------| | USA | Up to $10,000 fine & 5 years prison (Wireless Telephone Protection Act) | | UK | Unlimited fine & 5 years prison under Fraud Act 2006 | | India | Up to 3 years jail under Indian Telegraph Act, Section 25 | | EU | Violation of Radio Equipment Directive; carriers can block device permanently |
Even possessing IMEI changing tools is a criminal offense in many jurisdictions. Nokia, along with GSMA, maintains a global blacklist database. If a changed IMEI matches a legitimate device, you could cause that innocent person to lose service. With these, one could change the IMEI using
A: Absolutely not. Factory reset wipes user data (apps, settings). IMEI is hardware-based and remains unchanged.
A: Only if the phone’s motherboard is replaced by an authorized service center due to a hardware defect. The new motherboard comes with a new IMEI, and Nokia updates their database.
If you attempt to use software boxes or cracked PC tools (often advertised alongside these "codes") to force a rewrite of the IMEI on a modern Nokia, you risk "bricking" the device. This renders the phone permanently unusable because you can corrupt the modem firmware (Baseband).
A: No. That’s the engineer mode for MediaTek chips. Nokia Android phones either use Qualcomm (no such code) or have engineer mode disabled. Even if you access it, IMEI editing is password-protected and requires manufacturer keys.
