I have a Google pixel 4a. Unfortunately the screen recently broke, and I have to send it in for repairs. I still have my old Pixel 2, but it no longer has service. I'm wondering if there's a way for me to temporarily transfer my phone number from my pixel 4a to my old pixel 2, so I can use it while I wait for the repairs, then transfer my number back to the 4a when I get it back.
