I had the same thing happen and we're not alone. I swapped my Verizon Sim from my 2xl to my 3xl and it didn't recognize it. I then went to Verizon store and got a brand new Sim card and the same thing. No error message. Just didn't recognize. I called Google, which is where I got my 3xl from, and they had me do some troubleshooting and nothing. This was Thursday and yesterday I had them start the replacement process and I should have my new 3xl by Wednesday. Google manager told me that while there weren't a lot of instances like ours, there were some.
Also, I told manager how upset I was and that I deserved compensation for my inconvenience. She asked for and received for me a $50 credit for my Google store account. And just to be clear, not Google play store. It's already showing in my account and that means I'll have $100 after receiving the other promotional $50. Probably pick up the stand with that $.
If you have any questions, feel free to contact me.
I spent a couple of hours configuring my Pixel 3XL this evening. I went to swap the SIM from my Pixel 2 and the new device/SIM combination wasn't recognized.
On the chat with Verizon they told me that the SIM from my 2XL wasn't compatible with the 3XL and that they'd need to send me a new SIM or pick one up from the Verizon store.
Anyone else have this experience?
