IMEI Number

I need your help urgently. I would like to remove the SIM-lock from my P3300 and I need the IMEI number to buy an unlock code. I do not know this IMEI number because the PDA is second hand and has no box or any docs. I have read that you can recall it by entering #06#. The problem is, with or without SIM card in the PDA I can only access emergency numbers and cannot enter the for example the # character. The software keyboard shown on the screen has only the numbers and few letters. Who can help?

Erm, sticky label under the battery?

or
start -> settings -> system -> device information -> identity

it's not #06# but *#06#

What does the /02 designate when I type *#06#

When I type *#06# on my keypad, it displays an / 02 after the IMEI number. Does anyone know what that means? My ROM is rooted using CF-autoroot. I used triangle away and my phone shows that no custom rom has been installed.

That extra number is called IMEISV (IMEI Software Version). Apparently its a software version number (has nothing to do with firmware). Dont worry about that as almost every phone nowadays has that extra number. I checked my brother's Iphone IMEI and it had 09 as last 2 numbers.

[help] network problem - imei Matter - imei NG

Hi
So I bought this phone used.
I put sim card .. the phone shows the Carrier, even shows the APN settings . But I can't make calls (emergency calls only)
The imie of the device found on back is For Factory Unlocked 928A and I contacted ATT and confirm it's unlocked.
The Problem is : when you dial *# 06 # the phone shows a different imei number. And this particular number when looked up doesn't belong to any device on Earth. Using imei checker. And when going to service mode it shows imei: NG
So.
The first step on solution is to restore the original imei number that belongs to the device . That's logic right ?
How can I?
What about efs partition ?
I am on latest Nougat. Can't downgrade to 5.1.1 to root and try to change imei or restore efs
Trying downgrade in Odin give FAIL lol
What to do ? Excuse my English.

My phone doesn't detect SIM*card with lineage OS

Hi,
I recently bought a second hand smartphone Galaxy S4 GT-9505 which according to IMEI info was first delivered on 2013 r. and uses a Qualcom Snapdragon 600 APQ 8064T chipset and is powered by a 4.2 Jelly Bean android version. I use a French Orange SIM card that works normally on other phones.
I installed the recommended version of LineageOS for this device.
The installation went smoothly and the system boots normally. Nevertheless, after booting I can see a barred SIM card icon on top of the screen.
In the Mobile network settings only one entry is available, i. e. :
- Data roaming is greyed and not accessible
- Preferred Network type is greyed and not accessible
- Connected line identification is accessible
- Access Point Names is greyed and not accessible
- Network Operators is greyed and not accessible
Finding a tuto dealing with this kind of issue, I phoned *#*#4636#*#* . Then I could go to Phone info menu and there I could see this :
IMEI : my imei
Phone number : unknown
Current Network :
Signal strenght :
Voice Service:
Data Service: Disconnected
Voice Network Type: Unknown
Data Network Type: Unknown
Voice Call Status:
Roaming:
Set Preferred Network Type: here is a dropdown list. According to the tuto I tried every value but all of them failed to revive anything.
Is this a known issue and what can I do ?

Same can't find any info. I am using a oneplus T6
