How is the range of the mobile network?
See this Apple article: If you see No Service or Searching on your iPhone or iPad

You need Wi-Fi network, see this Apple article: If your iPhone, iPad, or iPod touch won’t connect to a Wi-Fi network

If Low Power Mode is On, charge the iPhone.
Wait until the battery is fully charged (100%).
The Low Power Mode will turned off automatically.
Then you can perform the cellular update, see this Apple article:
Manually update your carrier settings on your iPhone or iPad
