Hi Everyone,
I just bought a brand new s10+ from marketplace. I ran a full imei report and everything is clean & not blacklisted. It was a sprint phone however the provider I use is consumer cellular (uses ATT towers). When I put my sim card in it obviously said invalid sim and request it get unlocked. I wasnt concerned because I was going to convert it to unlocked anyways via odin like I did my note 9. I reflashed it via odin with the u1 firmware. However the same thing is happening it keeps saying invalid sim and the button for mobile operators is not showing. I have a tmobile sim card and if I put that in it works fine. Being though tmobile and sprint are the same thats why it works fine. I also have a ATT sim card, If i put that in I get the same invalid sim message. So it still appears to be locked somehow. Only sprint / t mobile sim works. I thought by reflashing to unlocked it would unlock the phone sim.
Just to be clear the phone is brand new and never was attached to any account.
Any ideas? I dont know what to do here.
Thanks!!
As I understand, phones that are locked to a network are not just software branded... also the phones hardware ID. So flashing a generic firmware is not enough. You need to get the phone unlocked from the phone's original operator
I found out what I had to do. I had to use a remote unlock service to remove the software lock on the phone. Its fine now. Thanks

Okay so basically, I bought an S4 from local ads, unlocked it via a service i paid for as the free one on here didn't work (couldn't access service mode).
Entered given code, unlocked fine, was using it for about 1 hour and then it said something along the lines of "sim card removed, mobile data will not be used until valid sim is inserted".
Now it shows that there is no sim inserted even if there is.
I've tried multiple sims, including the original network it was locked to, still no sim stated.
I've tried flashing a lower modem in Odin, i've tried flashing the latest ROM in odin, (all official).
I have now run out of ideas! I phoned samsung support and they didnt do any troubleshooting and said it needs to be booked in for repair, im pretty gutted as i'm without the phone for that... Was just wondering if its a common fault? and any easy way to fix it.
Thanks in advance!
I have an edge that is unlocked by tmobile.. in the app, permanent unlock (tmobile unlock app), it says.. "unlock failed" but below says permanently unlocked, unlock approved.. my understanding is this is a normal message.
When i went to the ATT store to test a sim.. they use their live sim, put it in, try to make a phone call but simply said it didnt work, isnt unlocked, which i dont think is right.. issue is i didnt see what if any error message there was.
Is there some step that the att rep should have done to get this on the att network besides putting it in the phone?
Thanks in advance for any info
edit: appears a special sim is needed, at least according to an online rep.. i was told to have them look up the IMEI with the MyCSP tool in the store to determine which sim.
VERIZON SAMSUNG GALAXY S4 using Canadian SIM says "This SIM card is not from Verizon"
Hi everyone, it's my first time posting..
I have a Galaxy S4 from Verizon that has been factory reset. I inserted my Freedom Mobile SIM and the setup wizard says: "this SIM card is not from Verizon wireless."
Gives three options:
Emergency Call
Turn phone off
Use WiFi
Trying to use the phone does not work.
I followed some instructions online to unlock the phone for free but upon using the dial option it says : "connection problem or invalid MMI code"
None of the codes worked even the one to obtain the IMEI. I can locate the IMEI but I just wanted to try this way to see what happens..
I had the person who gave me the phone contact Verizon for an unlock code and they said that the phone was unlocked and to call Samsung. Samsung said to call Verizon and for the last time...Verizon said it's unlocked.
Is there a way to fix this? Is my SIM card maybe the problem?
The SIM was working fine in my unlocked phone before it broke but I did have some issues before it was working and I was told to get it replaced to fix the issues but I didn't end up doing that since they were resolved on their own.
Are you sure the Verizon s4 is network unlocked and supports Freedom's aws frequencies?
Verizon said they were sure..
Sorry if this is posted somewhere, but I could not locate it. I bought a consumer cellular SM-J737U, which runs on att and tmobile towers. When I inserted the t-mobile sim, it prompted me to reboot for network change. I did, and I have full LTE for a few seconds then I got an error message saying this is an invalid sim, contact consumer cellular for help. So I know the sim works because I had full connectivity on there.
What do I need to flash to goto stock J7 stuff so I can use my tmobile sim?
I tried another sim and the same thing happened.
I'm trying to get my SM-G935V to work eventually work on Sprint. I already flashed my firmware over to SM-G935U. However, the Sprint IMEI check says it won't work on their network. At a Sprint store, the rep won't even try at a store to test out a Sprint SIM to see if it works. Would a Sprint SIM work in my phone before having my IMEI whitelisted (if that's even possible)?
My second option while waiting was to use Red Pocket. I got a plan, I got a SIM card, but I got "Error! Activation Error We are sorry, but due to the rules set by our underlying carrier, your phone number cannot be activated on our CDMA LTE service."
The third option was trying to change my IMEI which appears still legal to do in the US, but not possible to do on my phone because it won't bring up Engineering Mode with the codes. My thought was it was because my CSC still shows as VZW. I thought G935UOYM9CSC2 was XAA originally but I can't get that to show up.
Any other ideas on getting off Verizon with this phone?
Flash the Unlocked firmware on it. You will have to use a modded Odin, see the appropriate thread for that.
However, it will not change the IMEI. If the phone is currently locked in a contract... there is no way around.
Changing IMEI is illegal and will cause problems.
I had never switched my SIM card from the Verizon network to another one until today. It reboots into recovery and changes the CSC. This is after flashing to SM-G935U firmware. When I was on the VZW CSC the secret codes (USSD codes) wouldn't work. After swapping in an AT&T SIM card, the codes now work. Red Pocket white listed my IMEI no problem. Now if I can get Sprint to do it...
