I have 7 line with Samsung J3 emerge phone. All phones have same hardware, baseband and Android versions. I have paid off the phones and requested for unlock. Now, customer service is telling all phones are unlocked, but only 2 phones are supporting other carrier sim cards but other 5 do not.
2 phone supporting other carrier sim is having UICC Unlock message: "Your device is unlocked for any sim cards." And 5 phones does not support other carrier sim is having UICC Unlock message: "Your device is locked for sprint sim card."
I have tried to communicate this many time to customer representative, but they are saying, in sprint system phones are showing unlock so they can not do anything.
I have tried master reset, factory reset etc.. But nothing helped.
Solved! Go to Solution.
I inserted an active sprint sim on Samsung J3, i tried UICC Unlock on the phone with same results: The profile update cannot be completed... Internal error 407
Also I tried update profile option and on step one registering the device with network I get: Please contact service provider.... Internal error (-1)
I can receive sms and make calls with device.
Ok, I'll submit an unlock ticket for you. The phone will need to keep the Sprint SIM in it, it needs to be powered on and connected to WiFi. Once it's set up, send me a private message with the phone's IMEI, your name, and your phone number.
