That could be the result of someone trying to jail break the phone.
The IMEI numer is a specific identification number for that specific phone and if changed will render the phone useless.
It is normally recommended you Don't post your IMEI on websites. It is a security code for that phone.
Usually the IMEI number has to be reset by your network provider. It normally cannot be done directly from the handset. Did the handset accept the new sim card. Some handsets can be locked to a specific network and changing network can stop your phone from working.
Question edited for clarity.
So the phone was likely stolen in Australia and shipped to Sri Lanka for sale. For the technician to unlock it by playing with the IMEI, it must have been PUK Locked AKA a SIM Lock. To remove a normal customer set PIN Lock, you just do a hard reset which scrubs the phone clean and reloads the operating system with no lock.
A PUK Lock can only be removed by the carrier that provided the phone. The technician tried the impossible task of removing an RSA 128 bit encryption lock by playing with the firmware and corrupted it.
You have three choices
1. Give it back to the technician and tell him to fix his mistake
2. Send it to Nokia to have the firmware and IMEI reinstalled
3. Throw it away.

Never post IMEI numbers in an open forum like this. It is the unique number that identifies your phone from any other phone in the world. Those with malintent can clone a phone with your IMEI and you magically pay for their calls. This website gets 11 million views a year and the site has an excellent search feature!
Contact your service provider if it is the SIM code otherwise if it is the password you use to gain access, either remember it or factory reset your phone.
My first thought was that the phones doesn't have Bluetooth, but it does.

The key to the code would depend on the make and model of the headphones. Likely to the '0000' or '1111' or similar.
The most common PIN is four zeroes in a row, 0000. Two others you may encounter on some devices are 1111 and 1234. Try entering those when you're prompted for a PIN, starting with 0000, and most of the time, the pairing finishes successfully. If issue persist, proceed with these steps.

What do you mean by a 'restriction code'? If it is your password you might have to do a 'factory reset' on your phone.
If it has been locked with the IMEI code you will need to contact your network supplier to get them to unlock the handset.
It sounds like there might be an issue with your Nokia 2720 Flip after trying to edit a contact. Have you tried restarting the phone to see if that resolves the problem? If not, you may need to check if there are any software updates available for your device or contact Nokia customer support for assistance.
The Nokia Slide has no WLAN hardware. See the specifications here: https://www.gsmarena.com/nokia_3600_slide-2356.php . You might be able to find a USB wireless network adapter (dongle) or a wired network adapter. Then connect the USB adapter with a OTG micro-USB adapter. However, there could be driver compatibility issues. I've seen these adapter used more with Windows based computers (Win 98 and later).
I wish that I had better news for you.
