Fix cellular data issues on iPhone

When you don't have access to Wi-Fi, cellular data, also called mobile data in many countries, is your window to the internet.

However, you might see Could Not Activate Cellular Data Network as an alert. Other times, the top status bar may only show No Service or Searching. In all these situations, cellular data won't work.

If internet via 3G, 4G, LTE, or 5G is not working on your iPhone or cellular iPad, follow these solutions to fix the issue.

Last year, Apple introduced the iPhone 12 lineup. At the same time, the company also confirmed the handsets would feature 5G connectivity for faster cellular service. They did that alongside Verizon, with the carrier touting its network coverage and speeds. What they did not do, though, is tell folks that keeping 5G on would noticeably impact battery life on your new phone.
