there is a chance that the error was there because the Public Mobile esim is already installed and just not properly enabled
On Android: Check your Sim Card Manager and see if a Public Mobile eSim is there. If so, make sure it is enabled.
On iPhone: check Settings > Celluar and see if the eSIM is there. If it is, make sure the PM eSIM is set as Primary on "Cellular Plan Label" and "Turn on This Line" is toggled on
if you don't see the Public Mobile esim there, check the Welcome email, there should be a QR code for the esim for you to scan and install manually. If you cannot find it in Inbox of your email, check also the Spam box.
If the Public Mobile eSIM is there, disable or delete those non PM sim (eSIM/Physical sim).
If the non-PM sim is physical, remove it. If the non-PM sim is an esim, disable using the SIM Manager on the phone (or set as Secondary and turn off "Turn on this line" for this non-PM esim)
Then reboot the phone and click Reset All Networks on your phone and it will work. (Please note that Reset all Networks will also erase your saved Wifi and Bluetooth connections, but you just need to add them back after). Also, it is possible you have to reset it multiple times for it to work.
But no worries if it does not work, work with CSA_PM for a solution
