My nightmare with Verizon started 1 month ago, when I arrived in the US to visit the college I'm entering on fall. I wanted only a prepaid plan for data and calls, and I would purchase a new phone at an Apple Store. However, the salesperson convinced me to purchase the phone at Verizon, saying it was already unlocked. He assured me that once I was back in the country I lived - Brazil - the phone would be fully working with national carriers and so I believed in his words. Still in the US, I tried to use my phone with a T-Mobile SIM card. On doing so, my iPhone 7 showed me the typical message for locked phones, asking me to put an "authorized" SIM card to proceed. Afraid that my phone was locked, I went to many Verizon stores and called costumer service until I was again reassured that my phone was unlocked and would work fully when I was in another country. Last week I returned to Brazil, and the outcome couldn't be worse - the same phone-locked message displayed. I tried SIM cards from many carriers, hoping the problem was with a specific provider, but it wasn't. After calling Verizon more than 6 times, being transferred to many apple senior advisors and following all possible solutions Verizon provided, I still have a useless, locked phone. I had no advantages whatsoever on purchasing the phone on Verizon but now I'm left ignored by a company that is not honest with its consumers. This problem has consumed many hours of my time, and if I cannot get this issue solved I will have no options other than taking legal actions against Verizon.
