spectrum mobile
I switched from Verizon to Spectrum Mobile. With Verizon, my calls also came on my Apple Watch (though the watch does not have its own cell plan). With the switch to Spectrum, the calls do not also come to my watch. My iPhone is SE 2nd generation at ios 16.5. With Spectrum, my iphone now uses an eSIM, not a physical SIM.
Is there a setting to change?
