iPhone 12 Pro Swap SIM cards from old phone or not?

[kat.hayes]

I forgot to take out the sim card from my XS Max and put it into my new 12 Pro Max, I use Verizon. I activated my new phone and received a call on it, though I can still make calls on the old one. What should i do at this point? Should I still take the sim out of the old one and put it into the new one or leave it as is? Thanks.

If you can make and receive calls on the new phone, just remove the sim from the old phone and leave it out.

No need to put it in the new phone.

Has your old sim been replaced with an esim on the 12 pm ? ..... was the call a cell call or Wi-Fi call ?
