Where us the antenna on an iPhone 6s plus

Hello carolee176,

To help us better assist you, can you let us know more about the issue with your device? For example, are you experiencing an issue with the signal on your device, or are you receiving a "No Service" or "Searching" message?

The above details will help us plan how to proceed.

If you're getting a "No Service" or "Searching" error, please check out the suggestions outlined in this link, which provides some information that may be able to help resolve that issue: If you see No Service, Searching, or SOS on your iPhone or iPad

If you see No Service or Searching in the status bar on your iPhone or iPad (Wi-Fi + Cellular), your device isn't connected to a cellular network. If you see SOS or "SOS only" in the status bar, your device can still make emergency calls.

Check your coverage area

* Make sure that you're in an area with cellular network coverage.

* Turn cellular data off and then back on again. Go to Settings, then tap Cellular or Mobile Data. If you're using an iPad, you might see Settings > Cellular Data.

* If you're traveling internationally, make sure that your device is set up for data roaming. Go to Settings > Cellular > Cellular Data Options > Data Roaming.

Thanks!
