My cellular data says error and I can’t use my internet

So I left the house but before I even did my phone said no service I thought it was probably because where I’m at but once I arrived where I needed to be it showed the same and said that I had to update something in order for cellular data to work again and I’ve tried and it says it’s not connected to internet when it is and than on the bottom of the install thing it says 15.7.5. My iPhone is currently running on this security update will try to install later tonight but nothing has happened

If it doesn't help, remove and reinsert the SIM card.

If it doesn't help visit your carrier, maybe the SIM card is damaged, ask for a replaced (new) card. Normally it is free.

Ask also to check if the SIM tray is bent, as even a tiny misalignment can cause the SIM card to not fully connect with the internal contacts in your iPhone.
