I bought a Samsung SCH I545 S4. It was purchased under the assumption that they all come sim unlocked. When I insert my working AT&T SIM card into the phone, I get no service. It shows " SIM card is not from Verizon". When I try to make a call it show "Out of Service Area" and "Mobile Network not available". When I search available networks it shows Verizon wireless, Metro PCS, and T-mobile, No AT&T. I've tried factory reset, hard reset with no change. How can I get this phone functioning again. I am currently on baseband version I545VRUGOC1, Android version 5.0.1. Build number LRX22C.I545VRUGOC1

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.
I own a d2xar Galaxy S3 known as the SCH-R530X, and so far, according to the "Test Menu" you access from dial code *#*#4636#*#*, I have the possibility of US Bands (GSM-850/PCS-1900/WCDMA-850/WCDMA-PCS-1900), which always returns "Unsuccessful" when I try to select that band, or "Cellular (800-MHz)" which I am able to successfully set. I am running d2vzw's CM12 by Mastamoon, and I have tried d2lte's Paranoid Android, all of which had the same option. I'm attempting to connect to Verizons towers in hopes to connect the phone via StraightTalk. What are the steps to do this?
This model has no SIM slot, either.
Hello all,
It has been awhile since I've been on here. I apologize if I am posting in the wrong section (this forum has changed so much over the years).
Anyways, I am currently a T-Mo customer and just got a Metro PCS Samsung Galaxy SGH-M819N because I thought I could simply flash a rom that would allow me to use T-Mobile sim card. However, it turns out that it may not be that simple.
Can someone advise whether or not I am able to unlock the sim (without paying it through sites such cellunlocker.net) via flash? If so, would you be kind to direct me to the site or page which gives directions?
Thanks,

oK, i paid
4update:
I am ended buying an unlock code via eBay for $14.99. I enter the code and the phone no longer asks for SIM unlock code BUT now it does not register with any carriers.
i inserted my t-mo sim card into the phone, go to settings, and tried to automatically and manually connect to the tmobile network but keep getting the "unable to connect at this time. try again later" message.
i contacted tmobile via chat and provided imei number and sim card number but was still unable to connect.
i flash backed to stock firmware 4.4.4 and still no luck.
i checked my "device info" and under "phone status" it shows my phone number assigned to the sim card but not connecting to service provider.
Any ideas anyone? Please help.

I am able to connect with the stock Metro PCS apn.
I am also able to use TMO apn as well.
Make sure the apn is correct.
Go to more networks and then mobile network.
I recently unlocked my Galaxy J7 Sky Pro from the tracfone carrier (called them, got two codes, put them in and device said it is now unlocked).
Now when I try to insert a different sim card the phone seems to have no service, even though the sim card is recognized (asks me for the pin and logs in properly). In fact that sim card is a prepaid european one, from the german carrier O2, but since J7 Sky Pro can do LTE connection I though that should work fine?
What do you guys think, is there something I could do to fix the issue?
My exact model is:
SM-S727VL
And android version is:
6.0.1
One kind of annoying thing is that even though I unlocked the phone, it still shows the tracfone logo on startup. Maybe the firmware is preventing the european sim card to connect to a tower? Is there some "international" version of firmware I could update to to make it work?
Thanks for any suggestion!
