[Q] oX+ sim question

Ok so I am currently staying in Russia. And do recently I bought an Hox+ from eBay and it was shipped here. Now the guy never had a problem with it because it is newly bought. So it was shipped to me in the condition he sent it. Now I bought a factory unlock key and it is in my email.
So I went and cut my normal SIM card into a micro SIM card and put it in the phone but even when I restart the phone it just says No SIM Card. Not as an error I suppose.
I tried using a very old ATT SIM I had (converted to Micro SIM) but the phone didn't read it either. So I don't know what the problem is. My old phone reads my newly cut micro SIM but my phone doesn't. And I am thinking maybe because the att SIM is so many years old the phone won't see it, and maybe the phone won't see the Russian SIM card either, so my last option I suppose it to get a proper micro SIM from MTS.
What are your ideas? Also can I make the SIM unlock code show up on the screen using a secret code? You know like when people do that global phone code or *#06# code? My phone was also bootloader unlocked, relocked and os was restored too.

[Q] galaxy s2 hd lte sim problem

Hi Everyone
Heres a neat problem somebody may be able to shed some light on.
I have a samsung galaxy s2 hd lte I757M , it just expired off of contract from bell.
I wanted to unlock it and was ready to when I decided to check if the phone was locked by using *#7465625# and it says that everything is OFF so that means its unlocked, from what I have been reading.
I bought a sim card from roam mobility and booted it up. It did not ask for any code for unlock. It only says "No Sim card Emergency calls only. I installed it properly exactly the same way as the original one came out. Its clean to.
(Keep in mind I bought this phone brand new from bell never serviced or rooted)
I spoke to roammobility and they say the phone is supported on their network.
I thought the sim maybe defective so I tried it in a locked samsung galaxy s2 i9100m and right away when booting it asked for a unlock code, so to me it sees the sim is there. . I also tried it in a locked moto g with the same results..
Can anyone tell me why my phone does not read the sim or see it? Could this be some other type of lock?

Unlocked note 8 AT&T but no gsm sim works

Hi everyone
I’m kinda puzzled with this note 8 and need some advice. Recently got a note 8 from AT&T and since I was traveling I had it unlocked to use by a third party company ( since att doesn’t unlock until Device payment is complete)
I got the code, unlocked the phone successfully. Before I left USA I put a working T-Mobile sim to test if connectivity, no luck, it doesn’t work, I tried a Verizon sim, nothing works....
Note... this T-Mobile sim and Verizon sim if I put it on a different device it will work...
any reason why this is happening

The phone is not unlocked. Seems like an error happened when you got the unlock code. I'd try again.

Did you use this device on the att network? I mean, do you have it activated?
If you unlocked it by codes and the message after inserting the code is something like "unlock successfull" then your device must accept other GSM SIM cards.
Also, I would recommend you place a 5 min call with your device, with the att sim card and then insert again the tmob card.
What is the message when you insert the tmobile card in this device?

I did the same thing by using a Tmobile SIM during the unlocking process, and it worked on TMobile right after I unlocked it. It sounded like you did not unlock it using a different network SIM but using some other method. I am not sure if that mattered or not.
I then traveled to Asia, and I bought and used a local SIM card with zero issues. The 4G LTE was faster in that country than AT&T... LOL

Sim unlocked or not?

I've got a p40 pro (ELS-NX9) dual sim. I bought it off ebay reseller as sim unlocked and have used it on EE for over a year.
I am changing to the 3 network and their sim doesnt work - the phone asks for a sim unlock code. I rang EE and asked for a code to sim unlock, they said it would take a couple of days.
Today I got a message from them saying it is sim unlocked already.
Any ideas why the 3 sim doesnt work? Is there a way I can check?
I have both sims in the phone and tried them in opposite sides of the sim holder. The sim settings are fine. I have put google on it - would this make a difference? I dont want to go through the hassle of backing up everything again!!

”The SIM card unlock code, is the PIN number that came by default on your SIM card or the SIM card PIN that you set yourself. The purpose of having a SIM PIN is if someone found your SIM card they would not be able to make a call or access the info on it without first entering your SIM card PIN number”
Should be written on the SIM- big sim holder Card. ( default could be 1234 or 0000)

So why does my original EE sim work with no pin? The 3 sim is brand new and has no service, it arrived pre activated by 3, all I had to do is put it in the phone. I guess I should say network unlock instead of sim unlock?

A brand new sim come with the PIN written as on image, by default. You can remove it, change it, but first of all you need to provide the PIN code on the first connection to have access on it. It doesn't care if it has service or not.
It is better to try that SIM card in other phone. Maybe this other phone will provide you the same request.
Also you can ask a SIM (3 network) from a friend that for sure has the PIN inactive to see if it works on your phone.

Not in this case, the sim is pre-activated. It is a carrier code that is needed

I understand. It can be unlocked. I think it is not for free, but you will find solutions on-line or in service (not Huawei service).

SIM network unlock NCK
I have an 18 month old P40 Pro and currently have the above error when putting in the unlock code. I obly have 4 attempts left. Please help. Thanks Paul

According to EE the phone is unlocked, according to 3 it isn't blacklisted, waiting for a new sim now to try again.

Ifr it is locked, it will be the first P40 Pro locked that I have ever heard.

I've had a reply from Huawei, It was sold to EE locked to their network. According to EE it is unlocked lol! Back to EE I go I guess

Activating service on S7

I am trying to move my existing service to a S7 but not having any luck.
My daughter updated her phone a long time ago and this S7 was sitting around unused. She had purchased used and unlocked but when she was upgrading she deleted her files by doing a factory reboot. Will this take the phone back to being locked to the original carriers network?
Asking because I have been trying to move my SIM card over but it won't accept the PUK code that I got from my service provider.
When I startup with the active SIM card in it all I get is a message asking for the PUK code but doesn't accept the PUK code I have. Could this be the way it asks for the network unlocking code?

Trying to move my service to a Galaxy S7 that was passed on to me from my daughter. Installing SIM prompts for PUK code. Have received 2 different PUK codes from my carrier and neither is accepted!
Daughter had purchased this phone used but was unlocked and it worked fine for her. When she gave it to me she did a factory reboot to clear all of her stuff.
1) If a phone had been unlocked does it return to a locked phone when a factory reboot is done?
2) If the phone has returned to be locked to a carrier and the Sim from an alternate carrier is installed, will it ask for the PUK code but not accept it like this phone is doing?
3) How do I determine which carrier the phone is locked to?
