Carrier locked
I bought my iphone 14 pro almost 8 months ago from a guy online the mobile was box packed and was activated by me i paid a separate $500 tax here to my government so i can use sim card in it. I came to know that my phone was carrier locked by a US based company called sprint mobile. It was fully paid nor it was stolen i asked them to unlock it and if their is any outstanding balance i will pay for it but they refused because i didn’t had the account details of which this mobile was associated with the person I bought the phone from isn’t taking any responsibility and had blocked me if anyone can help me please let me know i have paid a huge sum on the phone and the taxes to the government. I have been using two phones just because of this issue.
