Using an eSim on Google Pixel 4a

The normal process for Android 11 is to go to Settings > Network and Internet, and hit the + sign beside “Mobile network”. The problem I faced was that there was no plus sign on my wife’s Pixel 4a. I could not install an eSim on top of the Sim card she already had on her phone.

I searched the web but found no good answers, so I’m documenting my fix here for anyone who needs it. Here it is:

Turn on aeroplane mode. Then turn it off. There will be a really brief moment when the plus sign will appear beside “Mobile network”, so you need to be fast to tap it. After that you’ll be able to add your eSim.

Hope this helps!
