Has anyone ever encountered a situation where the SIM card on iPhone 16 suddenly doesn't recognize and then it gets better immediately?

JD.com bought 16 self-operated in early March; Two cards, one China Unicom is a 17-year-old card, and the other China Mobile is a 23-year-old card; When I first bought it, I charged it with Xiaomi's charger and started to jump the sim card to reinstall it. I don't know why, but then the flash message from China Unicom jumped (full screen gray background, welcome to use China Unicom's service, cancel one below) OK); Two nights ago, I went to a restaurant for dinner and suddenly encountered a flash message that jumped Unicom. I don't know if you have encountered similar situations.

    There is something wrong with the sim card, just go to the business hall to replace the card

    Just change the card for free in the business hall.

    The SIM card is aging. I can solve the problem by taking my ID card to the business hall and changing it to a SIM card. There is no money

    First try two cards to change the position, if it doesn't work, go to the business hall to change the card

    Unicom's old sim card signal will play this when it is gone and there is again, but it will be gone when it is replaced with a new card

    I also had this situation before, and I couldn't recognize it for a day. My phone card was a card from the 3g era. I suspected that the card was broken, so I went to the business hall to change the card.
