Problem with SIM card recognition on the new iPhone 14 Pro after purchase

Hello, Apple Support!

I appeal to you for help with great respect. I recently bought an iPhone 14 Pro (the purchase was "blind" through a third-party platform), the seller assured that the device was fully functional and in excellent condition. I picked up the device at the pick-up point, turned it on at home and encountered a problem.

After turning on and initial setup, I tried to insert my nano-SIM card, but the phone did not recognize it, and I received the message "SIM card missing" or "SIM card not detected". However, the device looks new, and the SIM card slot is not damaged.

I went to "Settings" → "General" → "Softage Update" to check for updates and possible fixes, but I encountered an error:

"Checking the updates failed."

iOS version 26.0.1 is currently installed on the device

I would be very grateful for your help and recommendations on how to solve this problem. I would be sincerely grateful if you could tell me:

Is it possible to download and install a clean official firmware (the most current one for February 2026) from a computer, bypassing the error when updating wirelessly?

Model: iPhone 14 Pro

Thank you in advance for your time, attention and professionalism! I really appreciate Apple products and hope that with your help I will be able to make the most of my device.

With respect and gratitude

Apple does not offer email support and support in Russia is limited because of international sanctions and restrictions. Your carrier will be able to assist. It’s most likely a SIM card issue.

Apple не предлагает поддержку по электронной почте, а поддержка в России ограничена из-за международных санкций и ограничений. Ваш перевозчик сможет помочь. Скорее всего, это проблема с SIM-картой.
