[HELP NEEDED] “Not registered on network” on samsung galaxy grand prime + - General Questions and Answers

I bought this smartphone from Turkey and it is most probably a clone/modified handset. The IMEI number written on the back of the device is different than the IMEI number shown in settings. I currently am living in Bangladesh.
However as shown in the picture, in the settings there are two numbers under the heading of united Arab Emirates!
I tried flashing this phone with stock firmware but no result. Everything works perfectly except the SIM card. I have tried with several sim cards but none is working. Every time I tried to call it says 'Not registered on network'.
One of the street mechanic was able to fix this problem a few months ago but then I reset the phone and the problem came back. I couldn't find that mechanic due to covid-19 lockdown. Other mechanics failed to make the sim work. Other connectivity such as wifi and bluetooth are working fine. Please help me solve this issue. I can provide any details you want.

Resco tools and broken IMEI

Got my brand new HTC Touch Cruise the other week and it was working great. I then decided to try and Geotag my photos which apparently is as simple as changing a registery value. So off I go and download the trial of Resco Explorer 2007 and reg editor from their website and change HKLM\Software\HTC\Camera\P9 »Enable« to 1
Soft reset the phone and then the phone no longer connects to the network.
(The geotagging feature of the camera worked fine too.....)
I uninstalled the tools, did a hard reset and reloaded the original ROM to no avail - the phone still refuses to connect to the network (Telstra NextG - Australia) which it was working fine with before. I have also noticed that when there is no Sim in the phone the IMEI does not agree with the one on the back and when the Sim is in it says the IMEI is "Not Support"
Any help would be appreciated, I'm missing my new toy already!
Do a Hard reset and your problems should be gone. Easiest way is "Settings > System > Clear Storage > 1234". Remember to sync your contacts before you do it and good luck
I'd already tried a hard reset and loading the latest ROM (Which was the same as the one it shipped with) but that did not work.
Just tried doing it again the way you suggested and it's still broken.
Also on further inspection my IMEI when it doesn't have a SIM in to is almost the same as the one of the back but just has an extra 01 on the end. It still says "Not support" when I have the SIM in it though....
All sorted out.... It seems it was an issue with Telstra(They said they had a brief outage, and for some reason my SIM didn't reconnect to the network until they gave it a "Kick"), not the phone that just happened at the same time as I was editing the registery. Talk about bad luck......

Yes so next time your Polaris not working so blame always your operator if the device dont connect, The imei cant NEVER chance with a registry chance what ever you do with the device the imei never changes, with that numbers you cant mess with
you said the imei changed when you have the sim card inside and evidently you couldn't connect to the network because of that... so deosn't that implys there's a 'possibility' that bypass the hardware imei by doing something to the sim? we might be on to something here guys..

Maybe the IMEI gone. That's the hard part.
Sent from my SM-N920C
Check your imei,too see if it is still original,if it is 36000.....1 you in trouble
There is two ways to fix this but there is only one way working good
1 send it to Samsung (this way works good)
2 repair it with octopus box (this will get phone to work but you will loose signal during taking on phone or without .
and flashing stocks will get you in bootloops basically your phone is piece of junk)

Mi4i does has no signal with a specific and functional sim card

Hey!
I have a strange problem with my Mi4i (MIUI 7.5.2.0). The phone shows "no signal" or "emergency calls only" with a specific sim card, which works in other phones and used to work in the phone in the past.
The device works well with other sim cards too, even from the same provider. Just not with the specific sim card, which happens to be the one i would like to use. I cannot remember if the problem occured after an update (ota only).
I have tried so far, without any effect:
- a factory reset, without deleting the personal content.
- ordered and tried a new sim card from my provider
There seem to be similar threads in this forum, but they do not adress exactly my problem afaik.
Does someone has an idea what else i can try? I will provide further information if needed.
Thanks in advance!

Might be an unsupported band. What phone have tried the sim with?
Thanks for reading . Oneplus One, iPhone 5C. Sorry i forget to tell the sim card worked in the Mi4i. I didn't use the phone for a while and i might have updated it (ota) when i turned it on again recently. I guess the problem persists since then.
Any chance the update caused it?
did a full wipe and reinstalled miui (7) in fastboot mode. no change. the sim card works fine with other phones. the phone works with other sim cards fine too. just not with my main one

in need of help with my samsung j3

hi i recently purchased this j3 from a friend and it worked fine all i had to do was have it unlocked to work with my carrier this is where everything went haywire . after several attempts i finally received the unlock code and then when i put my sim card in it said too many attempts and needed a puk number i called my carrier and got it and entered it and didnt work i thought maybe hard reseting the phone would reset the amount of times ur allowed to enter this number i was wrong. so after some frustration i hard reset the phone a few times and tried every option that can be done in that menu now my phone wont even connect to wifi at the beginning of set up because it needs to verify my identity thru google account which that info i dont have this has become a horrible cycle for me and would apreciate any help or advice with this issue if u could email me this might be better my email is [email protected]

Bought used 970F with Magisk, relocked, flashed stock UI5, no network at all

*****FINAL UPDATE: THIS POST IS A WASTE OF TIME WANDERING AROUND SOLUTIONS FOR THE IMEI. THE REAL REASON IS THAT I WAS SCAMMED AND BOUGHT A STOLEN PHONE WITHOUT KNOWING, AND THE IMEI/IMEIs WERE CHANGED, so when I factory reset the phone, the IMEIs were gone. If you're in the same situation, see if you can return the phone. If not, the only thing you can do is sell it AS IT IS, because YOU WERE PROBABLY SCAMMED, LIKE ME, so please sell it declaring the state of the phone and the IMEIs.*******
****If you want to read the entire post, go ahead, but you'll waste all your time. You were scammed, it's a stolen phone, end of story.****
Guys I was really excited about this purchase, I tested network with the seller, on both SIMs, both worked great, 4G data, when I took it home I noticed the phone was BL unlocked with Magisk, which made me worry about any security issues or not being able to update. Relocked BL from download mode, flashed stock G970FXXSDFUI5 (I live and bought it here in Colombia), and I checked this was the same FW that it had while rooted with Magisk
Cleared data/cache, flashed successfully, warnings gone, but no network at all, this is what I have:
- Only emergency calls with any SIM in any slot, already tried different carriers
- Checked IMEI in national blacklist database imeicolombia.com, they're both clean
- When trying to make a call "not registered on network"
- When going into Mobile Networks - Select Network - Select Automatically is ON, if I try to turn off it instantly says "Error searching for networks" and the switch stays on, so no "Manual Search" button.
Already tried clearing data/cache of SIM Toolkit app, what am I missing? Thank you!
UPDATE: I went through all the process of unlocking BL again and rooting again with Magisk successfully following this tut
with updated Magisk, etc, but still no ntwk, will now try flashing other countries same/higher SW REV, will post any other update.
Additional steps: I tried putting 2G only or 3G only and reset APNs to see if "Select Automatically" switch was fixed but same story, it wont turn off and shows same "Error while searching for networks" msg right away
UPDATE 2: I wanted to share a video I found that shows the exact same error that I get in the "Mobile Networks" menu:
Altough I rly dont think it's the same situation, cause in that video, the phone has no signal at all, mine is able to pick full signal for emergency calls. I rly dont think my situation is that of hardware but some kind of software/activation/sim thing (It's not the SIM bc it works in any other phone)
Please someone help me, I've invested more than labor hours researching and trying to fix this, I fear I could damage the phone by flashing it so many times

A VERY VERY VERY complex process. It turns out the answer was a very simple one. They sold me a stolen phone with the IMEIs changed, so at the moment that I factory reset the phone, the "fake" IMEIs were cleared, leaving the phone with NULL IMEIs. In short, I got scammed, had to sell the phone declaring the situation, ofc for a quite discounted price due to the fact of it being a stolen phone.
ALERT 1: WHEN YOU'RE GONNA BUY A SAMSUNG PHONE, ASK THE SELLER IF IT CAN BE FACTORY RESET RIGHT IN FRONT OF HIM/HER BEFORE PAYING. IF THE SELLER SAYS YOU CAN'T, YOU CAN ALREADY GUESS WHAT'S GOING ON.
ALERT 2: NOW THEY CAN CRACK THE SAMSUNG PHONE IMEIS SO IF YOU FACTORY RESET, IT WOULD KEEP THE FAKE IMEIs, so the only thing you can do is go into this website:
IMEIpro - free Samsung IMEI checker
Check information about your Samsung cell phone - model, serial number, manufacture date. Verify Samsung carrier, age of the phone, purchase country, CSN number and other details.
imeipro.info
Enter the IMEI and the website will show you THE SERIAL NUMBER. COMPARE IT WITH THE ONE SHOWN IN THE PHONE. IF THEY DON'T MATCH, THE PHONE IMEI HAS BEEN CHANGED, LIKELY A STOLEN PHONE! DO NOT BUY IT!
This is the best guide I have for buying used samsung phones so far
