Hi, i have some problems with No Sim Card detected on Samsung Galaxy S III I9300 from T-Mobile (Austrian)
Firstly i unlocked the phone at the shop and was really unlocked on all sim cards but than i did a factory reset and the phone no longer detects sim card from other carriers, it only detects sim card from T-Mobile, It dosen't even shows the menu when you turn on the phone for network unlock.
I tryed using those secret codes to show the network unlock menu but they didn't work since the phone was updated to 4.3 firmware.
So i followed this guide on androible downgrade-galaxy-s3-i9300-android-4-3-android-4-1-2-jelly-bean-firmware
To downgrade to 4.1.2 firmware along with provided modem file. The secret codes now do show menu's but when i click on UMTS RF NV it says it's not supported.
Also instead of downgrading to T-Mobile 4.1.2 Firmware i downgraded it to Orange 4.1.2 Firmware hope that dosen't effects it in anyways? Phone otherwise works just fine IMEI Number shows OK.
I tryed 2 different SIM cards from orange none of them worked, it only detects SIM from T-Mobile.
To recap it all agean: I wish to unlock this phone so i can use different SIM card's but the phone is on NO Sim card, emergency calls only but when i insert T-Mobile Sim it works, Also there is no Network Unlock Menu shown durning turn on or reset since i already Unlocked the phone once with a code. Does anyone has any clue how to fix this or unlock it without rooting the phone.
Just got an Xperia M4 Aqua and I am trying to work out if I can unlock the network by getting an unlock code of ebay, etc?
When I go into the service info menu and select sim lock I see:
[o] Network 5
I believe the right hand number (5) is the number of retries but usually you see an [x] on the left not a [o].
See a few conflicting things on the web about whether this can or can't network unlocked and hoping someone can give me a straight answer.
Thanks.
Normally, you can apply for SIM unlock from your carrier, at least in the US. Check with your carrier
Are you sure it's not already unlocked?
My Aqua came network unlocked straight out of the box.
You can try chimera tools,,, it based on Windows version,, also it's better to root your phone before use chimera.
I have a tmobile lg v30 that was unlocked with device unlock tool... used it for a year on att. Then I went to xfinity mobile with an Iphone. Put the v30 away for a month.
Was gonna give to my friend to use on tmobile. When you put a tmobile sim card in it will not connect to any network. Will not work with att sim now either. Tmobile says its carrier locked and they
cannot unlock it now. ????? Says I have to get the original carrier to unlock it... They are the original carrier. Device unlock "when you try Permanent unlock says" Unlock Failed Unlock Approved : Mobile device is permanently unlocked.
When you try Temp unlock it says Unlock Failed Unlock Approved : Mobile device is temporarily unlocked until 02-Aug-2019.
When you put tmobile sim in the apn is there but you cannot edit or add apn.
When your put any other sim in the apn is empty and you cannot add apn.
Phone is on Android version 7.1.2

If it's a T-Mobile H932 and you want to use it on T-Mobile, why does it need to be carrier unlocked?
If it won't work on T-Mobile, have T-Mobile repair it
It's not a carrier unlocking issue, at least if you want to use it on T-Mobile..
Because it’s not on an account now and T-Mobile says it needs to be network unlocked. Before they can add it back to their network.

T-Mobile H832 does NOT need to be carrier unlocked to work on T-Mobile, since it's a T-Mobile device.
If they are telling you that they're lying or they don't understand what you're asking. Maybe you confused them with unnecessary details about your attempt to carrier unlock it in the past.
Stop mentioning that to them and focus on it's T-Mobile device that needs to work on T-Mobile, period. And they need to replace it or repair it if it doesn't.
If some incompetent support person doesn't understand that, then go to another store or make another phone call.

Just to be crystal clear here,
are you sure about that? Is there something you're not telling us?
We ARE talking about T-Mobile H932 and not Puerto Rico H932, right? You BOUGHT it from T-Mobile, right?
If the answer is yes, it's T-Mobile H932, then this statement stands:
T-Mobile H832 does NOT need to be carrier unlocked to work on T-Mobile, since it's a T-Mobile device.
You need to find competent support person and do NOT mention anything about carrier unlocking to them... until the phone is working on T-Mobile with no problem.
THEN, you can ask them about carrier unlocking it to work on other carriers.
I purchase a like-new condition Samsung Galaxy S9+ phone from Amazon Warehouse for international travel coming up in couple days. I figured I would have a better chance of getting an authentic phone from Amazon than from ebay sellers. I received the phone yesterday, and here is the situation with the phone:
- The box of the phone says "unlocked by Samsung"
- The sticker on the back of the phone has the model # SM-G965UZBAXAA and IMEI number of a factory unlocked phone
- The actual IMEI of the phone however shows model # SM-G965UZBAATT, which corresponds to the AT&T carrier locked phone
- When I turn on the phone, it shows T-mobile screen and has T-mobile apps on it
How do I determine whether this is a AT&T phone, or a T-mobile phone or something else? Unfortunately, I do not have either TMO or ATT sim cards that I can use to check which network the phone works on. How do I know whether this phone is unlocked and if it is will work internationally? I am not sure how to explain the imei of the phone coming up with ATT model number, yet the phone shows TMO screen.
Please help as I need to get this resolved today, and don't have time to purchase another phone. Thanks much in advance!!

put any sim in it and it should work these phones are multi carrier means all the us models are the same if its att imei id say its unlocked since obviously last used was t mobile but if you put any sim in it other than att it should accept it and not say unnsuported sim and or ask for unlock code
to further this as i said the us models are all the same. They have a file called CSC which determines carrier based settings you can put in a tmobile sim and it will repersonalize for tmobile then swap to att and att will show up..
Its the way of the future and actually quite nice as one firmware pretty much covers all carriers other than specific user data which is that carriers apps
it may be unlocked obviously the listing was wrong but xaa is factory unlocked for sims, You can reflash xaa if it is unlocked for non carrier branding,But id put any sim in and see

Thanks for your response. So if the previous owner put a T-mobile sim in the AT&T phone, then would it show the T-mobile screen at startup, and also have the T-mobile branded apps?

Thanks again! Is it safe for me to do a factory reset on the phone? I wasn't sure if it was rooted and whether a factory reset might brick it. If I do a factory reset, what would it restore to - the AT&T or TMO configuration, or something else?

I downloaded the phoneinfo app, and here it what it shows:
Firmware's CSC code: XAA
Active CSC code: TMB
IMEI check shows model ending in: ATT
That made me highly confused as to whether this was a AT&T phone, a T-mobile phone or whether it was originally sold as factory unlocked.

So originally it was a att device. Who ever used it used it on tmobile but on xaa which is debloated unlocked

Under Service Provider SW ver., it shows TMB/XAA/ATT
I am trying to understand what this means, why would it show TMB, XAA and ATT? Does it mean the phone was originally AT&T, then someone installed XAA firmware on it and used it on T-mobile. If that is true, is there a way for me to verify whether the current installed firmware is XAA?

That is correct. You see it now. The third csc code is the original device. The second is what csc you have running. And the first is or was sim inserted.
Look in settings about phone and software info. At the bottom somewhere it should show you

Yes, what I pasted above is from about phone->software info. It shows the service provider sw version as TMB/XAA/ATT. Thank you!!
I just received my Samsung S23 Ultra SM-S918U1 direct from Samsung.
Engineering mode (*#0011#) was unlocked and worked out of the box as did all other dialer codes.
Once I inserted my Verizon Wireless sim, the phone self provisioned and downloaded SAOMC_SM918U1_OYM_VZW_13_0014_VZW/VZW,XAA/XAA carrier settings.
Now none of the dialer codes work even if the sim is ejected and a factory reset performed. Is there anyway to restore them that they will stick with Verizon carrier settings?
Did you try sim from different provider?
