It can interfere on some networks. Turn Limit IP Address Tracking Off for the travel eSIM line, then retry.
Should I choose Abroad / Travel eSIM Only during setup?
For travel eSIMs, choose the travel / abroad options and select Not Now for Low Data Mode when asked.
Can a carrier-locked iPhone use RoameSIM?
