When iPhone says no service it means you can’t use it for the basic things, such as texting, calling, and using mobile data. The only way to access the Internet is by connecting to a Wi-Fi network. You won’t be able to use the mobile internet until you get rid of the error. The same thing goes for messages and calls. The issue will appear in the areas with no network coverage, or in the areas where network coverage is poor when you can also see a message “searching for service”. Some other reasons for no service on iPhone are damaged SIM card, the fact the card is not properly placed in the tray, or a software bug. The problem may also appear after iOS upgrade.
