Why does my iPad say " No SIM " in the upper left corner

Hi Edwardtracey,

Welcome to the Support Communities!

It sounds like you have a cellular data plan and there is no service where you currently are.

The article below will explain this feature and how to turn the setting on/off.

The article has more details and screenshots, but I've quoted highlights below for you:

iOS: About the Cellular Data setting

Cellular data is used for data communication in cellular networks. It does not affect your ability to make or receive phone calls or to use Wi-Fi networks for Internet connectivity. If you turn off cellular data, you will be unable to:

• See the cellular data icons in the status bar (for example, LTE or 3G).
• Send or receive MMS messages. However, you can still send and receive SMS and iMessages if you're connected to a Wi-Fi network.
• Retrieve or listen to new Visual Voicemail messages. To retrieve these messages, enable Cellular Data.
• Use Personal Hotspot.

You can adjust this setting by going to:

iPad: Settings > Cellular

Additional Information

You can also enable or disable cellular data for certain iOS features from this setting:

I hope this information helps ....

Have a great day!
