Apple no longer activates its proprietary SIM cards for iPads with cellular data

You may need to perform some extra legwork to connect an earlier iPad to cell networks. MacRumors has learned the company stopped activations for the Apple SIM in certain iPads as of October 1st. If you're affected, you'll have to either contact your carrier (and likely obtain a SIM card) or use an eSIM in newer tablets. This won't affect you if cell service is already enabled.
