Is there a "dummy" sim to stop the "no sim installed" message

Every time an iphone without a sim is turned on, a message pops up that "no sim is installed." I have searched for a couple of years now to find a way to quiet that message. There simply seems to be no way. Is there a "dummy" or "stub" sim that will inform iOS that the user doen't want a sim and has no intention of using cellular function, and at the same time satisfy iOS that a sim is installed?

iPhone 5, iOS 10

Get one from your old phone or ask your phone carrier.

put the device in airplane mode.

Thank you all very much for your replies. So that I am in sync with everyone: the phone I am refering to is an iPhone 5 running on iOS 10.3.4, the latest version available for this device. The point of this discussion is to make use of an old device as, Mr. IdrisSeabright puts it, an iPad. I have no need and have no desire to use this device as a cell phone. An Internet connection via wi-fi is plenty useful.


Please correct me if I am wrong:

1) It is not the device, but the OS which is demanding that a sim be inserted. After the device is powered on, it functions to its full capacity other than cellular with a wi-fi connection. As long as the device is not turned off, the "no sim" message will not appear (except when exiting airplane mode).

2) If put in airplane mode, wi-fi is also halted, rendering the device useless other than for offline functions.

3) A valid sim, i.e., one which connects to some carrier's network is required to fulfill the iOS requirements. If an old sim is placed into the phone which is no longer under contract, then a message "invalid sim" is issued.


(Bonus for your DIY folks: it is possible to use a mini-sim in a nano-slot! CAREFULLY trim the mini-sim's edges to nano- size without damaging the gold fingers. Don't forget to cut a tiny triangle off of the sim from the right corner. Handy for getting a 3G or 4G sim.)


Y'all take care

That's a distinction without a difference. The iPhone hardware and iOS are inextricably linked. You may be able to get things to work for a while using a variety of workarounds. But that is all they will ever be. You'll do something different and the message will pop up again.
