SIM card is not working
I bought the iPhone 12 mini from Kanpur Reliance Digital a month ago 07/10/2021, when I bought the mobile, I told the salesman that I had to leave India, so would my iPhone work for another country's SIM card when I left India, then the salesman said that my mobile normal will work if Mai goes to any country, but when My Came to Africa, only India's SIM card works in my mobile and the SIM card outside India is not working
