Hello. Half a year i bought D6603 that was connected to some uk provider, the man i bought from had unlock code. So on first run we inserted sim that is not acceptable, so it asked for unlock code, after code was inserted, sim lock was unlocked.
Now, i had a problem with my phone, so i brought ir to repair center, after all fixes they reinstalled OS , and after that, now i cant use my sim card. i wanted to insert that code again that i have, but it not allows it. when i go to that "secret" menu of sony, in sim card section i see all parameters are 0, so that means that enabling all simcards by code are disabled.
Please help, how i can unlock my phone, that i could use my own sim card? I have that unlock code, but i can't insert it and unlock.
Thanks.
P.S. now i have tried to hard reset it as it shown in this video:
youtube.com/watch?v=4al5k-mooc8
after this "hardreset", in secret menu , sim lock tab shows not zeros anymore, but unknown error.
I have one galaxy s8 which was claimed to be unlocked b4 buying it,put in my sim and it's writing "invalid sim card,sim card not supported"if i go to settings and search for available networks,it will bring different networks but wont allow me to register on it.if i try to call...it will say "not registered on network"
I made an enquiry and they said if it is locked,it should prompt for an unlock code immediately i put my sim inside.even if i wana unlock again,d phone is not asking for any unlock code neither is it asking for unfreeze code.i also tried secret codes with it and it is not working #7465625*638#.it is a branded at&t phone
You may need to configure the APN for the new carrier manually. Go to settings, connections, mobile network, then APN (Access Point Names), select add and type in new APN settings.
However if that doesn't work, It may be hard locked. Meaning that an invalid sim unlock code was entered too many times. In my past experiences if it doesn't prompt you for the code when you enter a new sim card it is either hard locked or already unlocked and needs the APN settings configured. However after inserting a new sim card the phone would normally configure the APN automatically and only on occasion would I need to modify it to get data/text working properly.

invalid sim card,sim card not supported means it is locked device, i would like to help you to unlock it if you're interested
I'm facing this same issue. When I got the phone I installed an unbranded firmware (XAA/XAA/ATT) and I've since upgrade to Oreo. I can't seem to restore an ATT firmware so I can be prompted to enter the unlock code. Any suggestions?
make sure you using non at&t sim and it must be an active sim card. submit an unlock request to at&t on their website or use an unlock service like attunlocker.us to get your code.

The issue is there's no prompt to enter the unlock code.
is the SIM card active that you are using? what SIM is it?

Yes, it's a T-mobile SIM.
Sorry to necro, but does no one have a solution for this? I've seen plenty of threads such as this but very few solutions.
Necro double-post, I'm really asking for it...
First, you have to get an unlock code from the carrier. I had AT&T and it told me my phone was active under an account (previous owner). When you call AT&T and ask for an ulock they loop you to the website and you can't progress there, so you just have to ask for "customer service" twice and then get to the second level support. They can get you an 8 digit code for unlock. But I still never got prompted for the code and neither AT&T (5 calls), Cricket (3 calls), or xFinity (3 calls) could tell me how to get to the unlock screen. The following did it.
My solution was to use the following method, as found on https://www.tenorshare.com/samsung/samsung-unlock-code.html:
Step 1: Open the phone and type #7465625*638*# in the dialer.
Step 2: Then, it will ask for the Samsung Reset Code, it is an 8-digit code.
Step 3: Provide it and you will be done.
Been searching for some time and I'm unable to find any concrete information on Project Fi and non-supported phones, specifically the HTC U11. Is it possible to use the U11 on Project Fi? I found APN settings but not sure if this really means I can use my U11 on it. From my research it seems like I have to do this:
1. Buy Project Fi and activate the SIM on a Fi compatible device
2. Delete APN settings and remove my google account from the compatible device
3. Insert SIM in my U11 and manually configure the APN settings
Can anyone confirm? Don't want to switch over and find out my U11 won't work!
Hello everyone.
From months I have problems with one of mine SIM Card. Before the root and the FW update my Vodafone SIM card worked good (with also 5G). After the processes mentioned above it stop working.
Premise:
I’ve switched the SIM from slot 1 to slot 2 (don’t work)
I’ve cleaned the SIM card (don’t work)
On an iPhone the sim work perfectly.
It’s possible to solve this problem and rehabilitate the SIM? I really need it because the actual SIM some times lost the connection.
Uses the code in the dialer phone *#*#4636#*#* verify in information in menu (uper right) the bands, select your zone or automatic mode and ready

Thanks for the answer but I can’t find the correct section for reactivate the 5G. Obv the code work but I can’t find where is the section
My Tab P11 Plus has been updated to Android 12 recently. The SIM card is detected and shows the mobile provider name on the Wi-Fi and network settings page, but when you tap on it to open the detailed SIM card settings page, nothing happens. I tried a different SIM card and it works ok, the only difference is that the other SIM card doesn't support VoLTE while my original one (that no longer works) supports it. I also tried to remove the PIN from the SIM card and reset all the network settings.
The SIM card works ok in other devices.
Is there anything I can do via the adb, to delete all the SIM card related data? I don't want to do a complete reset, as it takes almost a week to setup evetyhing from the scratch again. Thank you.
