- Tap Add SIM and see whether Download a SIM instead is offered
- ROG Phones have an X Mode that suspends some connectivity — if the SIM menu vanishes, switch it off first
Things to know
- ASUS does not roll eSIM out to every market at once, so a Thai-market unit and a European one of the same model can differ.
- ASUS tablets and laptops with built-in 5G are a separate line from the phones — read each model's spec sheet on its own.
What to do next
This handset is ready for eSIM, so the next decision is the destination, then the number of days and how much data. You can install the profile at home while still on your own Wi-Fi without starting the plan's clock, and switch the line on once the aircraft lands. That is the whole point of doing it before you fly: you are not hunting for airport Wi-Fi to scan a QR code with.

FAQ
Does the ASUS Zenfone 12 Ultra support eSIM?+
The Zenfone 12 Ultra supports eSIM on the global variant, according to the manufacturer's own specification.
How do I confirm eSIM on the Zenfone 12 Ultra actually in my hand?+
Open the settings menu using the steps on this page. If you see an option to add a cellular or eSIM plan, the handset supports it. That check beats going by the model name, because the same model sold in a different market can ship with a different SIM arrangement.
I bought this handset abroad — does eSIM still work the same way?+
The eSIM chip itself is not tied to where you bought the phone, but some market variants leave the feature out at the factory, and a handset bought on contract from a carrier may still be network locked. Check those two things first: whether the eSIM menu exists, and whether the phone is carrier unlocked.
If I install a travel plan on this phone, does my home SIM keep working?+
Yes. A handset with eSIM holds several profiles and can keep two lines active at once, so the normal setup is the eSIM carrying data while your usual SIM stays in for calls and SMS. Your home SIM only runs up roaming charges if you leave data roaming switched on for that line.
