Question iPhone cellular not working after temporarily removing SIM card

[BobMcSmith]

I have the newest generation iPhone SE, and I temporarily removed the SIM card and put it in an older phone of mine. I took it out after a couple minutes and put it back in my original phone and I got the pop-up: "Your Apple ID and phone number are being used on another device." The SIM was recognized though, and it said I had service. However I could not make or receive phone calls or use data. I've tried resetting my network settings, removing the old phone from my iCloud account, and even factory resetting my phone. I called my provider (Spectrum), and they said that everything is working on their end, and that it's a problem with my device. Did I somehow break the SIM card? I assumed that if I had physically damaged it, it wouldn't even be recognized by my phone. Any help is greatly appreciated, thanks!

Yeah, I already signed out of iCloud on the old phone and then removed it from my account, and still nothing. Thanks!

No, sorry if I explained it poorly, I’ve had the phone for about a year now, I just took the SIM out for a couple minutes, and I can’t reconnect to any of my cell services.
