I can't do unlock iphone xs with no reason
I just bought a second hand iphone xs from ebay. Before deciding order I used many IMEI checking services to ensure device is not iCloud locked or blacklisted.
All checking services returned same results "CLEAN". I also use special checking service to ensure this phone is not financed or in contract.
But there are 2 problems bellow when I request an unlock via both AT&T website or an Unlocking service.
1. I use AT&T unlock portal to request unlock but confirmation mail never come despite of changing many browsers (IE, Chrome, FireFox or even Sarafi) and many email address (yahoo mail, gmail, company business mail, yahoo japan mail)
When I input IMEI number in above link it still recognize my device correctly and I passed through 3 steps with no issue and no error.
I research many similar issues in this forum and tried with different solutions solved their problems but no luck.
2. I was disappointed after many tries and find a premium unlocking service to hope that they can unlock my iphone but after 9 business day waited, the unlock process failed with reason "Denied (Non AT&T IMEI)" .
I'm sure that my iphone is locked with AT&T.
So I wonder where can I find the answer for my problem ?
I post my problem here and hope that anyone in this forum can help or instruct me to resolve the problem with my device -_-.
P/s: I live in Japan but I'm going on business trip in Vietnam now
