If you see No Service or Searching on your iPhone 12, or can't connect to a cellular network or cellular data, your iPhone might have a hardware problem. iPhone hardware problems could arise when your iPhone gets wet or is dropped. These accidents are often inevitable, but can damage the internal hardware of your iPhone. Before visiting our store, we recommend contacting your wireless carrier to ensure there are no issues with your account. If your carrier confirms that there's no issue with your account or network, but you still can't connect to a cellular network, contact us to get it fixed. Express Service uses only the best quality parts available on the market to ensure that you leave the store with your iPhone ready to connect to a cellular network.
