I just got a Sprint galaxy note 3 and im trying to make it cricket with the new gsm network. I ordered a sim card and I attempted to do the sim unlock but it is not working. I rooted it and verified that it is rooted with an app to check it. I also installed super su like the directions said and also installed region lock away. I still cant get the phone to accept the sim. It says "invalid card". I checked the Stats on it and it show network unknow. It doesn't even show the phone number program onto the sim. When I take it out it switches back to sprint.
Sprint sim slot is only for lte on sprint in the us...
You need a gsm model such as att or unlocked t-mobile note 3!

I have problems with a Samsung Galaxy S4 SGH-I337M that I bought. It only detects certain SIMs.
It works with a Fido SIM. But I want to use it with Rogers. When I insert a Rogers SIM it just doesn't detect the SIM card. I have tried a few different Rogers SIM cards with the same result. All I get on the status bar is "No SIM card | Emergency calls only".
Besides the Rogers SIMs, I tried an MTS and a Telcel (Mexico) SIM with the same results and none of them prompted me for an Unlock Code request. Then I inserted a MoviStar (Mexico) and it prompted me for an Unlock Code. So I bought an Unlock Code on ebay and entered it. It gave me a message stating that the phone was successfully unlocked.
So after unlocking it, the phone works with the MoviStar SIM and with the Fido SIM but it does not detect the Rogers or MTS SIM. Does anyone have an idea what the problem could be? Rogers and Fido are the same company and use the same network, yet only Fido's SIM works.
I have done a couple of factory resets and keep getting the same results.
Forgot to mention, I am running stock firmware, Android 5.0.
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.
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
