Not two eSIMs: one eSIM and one physical SIM can be active at the same time.
Why is my eSIM not working on the Asus Zenfone 12 Ultra?
Check four things in your SIM settings: the travel eSIM is turned on, it is chosen for mobile data, data roaming is on, and your phone is not locked to a carrier. Then restart it.
What if the eSIM is stuck on “activating”?
Activation needs an Internet connection: stay on Wi-Fi for a few minutes, then restart the phone. Many travel eSIMs only connect once you land, so “No service” before you leave is normal.
