After purchasing the iPhone 12 Pro Max from shopiosx, I encountered an issue where the device did not have a SIM card. I had to reach out to my carrier to get it connected and have a new one sent to me. However, I must commend the shopiosx team for their prompt response and resolution to the problem. They provided me with a gift card for the inconvenience caused, which was a nice gesture. It's worth noting that while shopiosx is a good company with responsive customer service, they do not provide cell service directly, so be prepared to handle any network-related matters on your own.
