Why does my iPad always tell me I have no sim?

Hi Oakbayguy,

Thanks for using the Apple Support Communities! If you are planning to use your iPad without a SIM card but keep receiving No SIM messages, you may want to try turning on Airplane Mode, then individually turning WiFi and Bluetooth back on as outlined in the following article:

Use Airplane Mode on your iPhone, iPad, or iPod touch - Apple Support

Cheers

At startup the message will appear but you can remove it from showing in the top left corner by turning cellular data off. On my iPad 2, I found an inactive sim, placed it in my iPad & then was able to turn off cellular data. If you have a later model iPad with Siri, you can simply tell her to turn off cellular data.

i have i pad 2 with wi and cellular, it is not accepting the new sim card , i trie call tips given like reset networking etc airplane mode, but it shows no sim on left hand top and no sim installed pop up , kindly guide

To remove the reminder just tell siri turn off cellular data

Actually, my ipad (3rd generation) with sim, was showing in top left corner "no sim". After i asked siri to turn it off, it just went and become "iPad". When it happened, the reminder never showed up again. Make sure you have "ipad" in the top left corner, if not, re-ask siri, maybe it should go well.
