Different IMEI and phone works only on 2G network

Hi!
I bought an Note 3 N9005 and I noticed that the imei the phone displays it's different than the one on the back and on the box.
I have to select the network manually and it only works on EDGE when I'm on the web.
Could it b3 that the phone was sim locked and during the unlocking the imei was changed?
If so, what can I do?

is there a How to on Canadian Carrier Switching?

I've looked all over the forums and all the threads on carrier switching refer to switching US S8 variants to US carriers.
Can someone please explain or point me to a thread that explains how to carrier switch Canadian providers that would be fantastic. In particular I want to go from Rogers to Freedom Mobile (aka wind mobile) . My phone has been factory unlocked.

I can tell you from experience that freedom does not have any carrier specific features, so doing a firmware switch wont benefit you in any way I dont think.
You can however go onto sammobile and download the firmware for freedom and flash it using Odin. Again probably no real benefits. You would benefit if you were going the other way tho, as Rogers, Bell and Telus have carrier specific settings in their firmwares.
But since you are carrier unlocked, you could try a factory reset then put your freedom sim in it and boot up. It might install the freedom files. My S7 worked this way when i went from a Bell locked phone to a Koodo sim...
Edit: That link has an unlocked canadian firmware as well, you could use that firmware too.

Open the dialer and type *#243203855# then select GLW, this will change your csc to wind mobile/freedom, it'll wipe your phone..

Hi Peachpuff. I have an unlocked S8 phone from a Bestbuy canada marketplace seller. I tried using your code to change to the Telus CSC so I can get VOLTE but got the invalid MMI code error message. The about phone says its an SM-G950FD, and the only code the phone appears to accept is the one displaying the EMEI.
Hope you have some guidance on that ?
Thanks

That's not a canadian s8, its an international one, so that code won't work and i doubt you'll get volte working at all.
Just enjoy your root friendly multi sim phone.

Galaxy S8 US Cellular

Hi .
I have bought a S8 locked to US Cellular on eBay, clean , not blacklisted and when I try a SIM card from my operator does not ask for unlock pin code and remains without registering on my network.
Does anyone know any website or any method to unlock It?
Many thanks in advance.

Does it have a unlock app in apps drawer or in settings. It may be unlocked. If ure sim works. WhT carrier you on.

Thanks for your answer.
I live in Portugal and I tried 2 different SIM cards. The phone shows in upper left screen the message "SIM blocked". I searched for an unlock app too but I can't find any like in T-Mobile phones I bought in the past.

US Cellular is a CDMA network provider whereas in Portugal you probably have only GSM networks.
I think you should look into this and investigate this issues as well.

Another info: I flashed with Odin with the latest USC official Rom from sammobile. Can be this the cause?

This is 950U version and therefore has the GSM frequencies as well.
Even if it was only cdma it would prompt to insert the network unlock code....

Any help?
WHen I put a sim card it appears a forbidden sign on the top, where I should see the network signal...
