Do I need an additional line for my Apple Watch SE 2?
Purchased new SE2 watch for wife. The 'fall' notification feature is critical. I have her set up through her iPhone, but don't think the emergency call would be placed if she is out of range from her phone. Is that correct? If I get an additional line, would she send and receive calls only on the additional line, or would she still have usage of the line connected to her iPhone? Using ATT Mobility.
