Who I have the same questioned this topic

Hi

I recently consolidated my two lines on an iPhone XS, at my home I have a Network Extender and for some reason the Network Extender blocks the e-sim service.

This issue is driving me insane, if I turn off the Network Extender the e-sim goes back to normal but with low signal.

This issues doesnt affect other devices or the line with the SIM on my iPhone, the issue is only with the e-sim line.

Please help
