常见问题
My phone has two physical SIM trays — does that mean it has no eSIM?+
Not necessarily. Some models carry both two physical SIM trays and an eSIM chip, while others carry only one or the other. The surest way to know is to check the settings menu using the steps on this page.
Can I check compatibility before buying anything?+
Yes. Checking the settings menu, dialling *#06#, and using our device checker tool on the site all cost nothing, and should always be done before buying a plan.
I see an EID after dialling *#06#, but 'Add eSIM' is greyed out — why?+
This is usually caused by carrier locking or a software restriction set by the original operator. Check the lock status directly with that operator, since the hardware chip may already be present but unusable until the lock is removed.
Can I run the eSIM alongside my existing physical SIM at the same time?+
It depends on the model and software version. Some phones can run two lines at once, others only one at a time. Check this limit on your own device before relying on it.
I'm not sure which regional variant my phone is — where do I check?+
Open the device information menu to find the model number, then compare it against the manufacturer's official published data, or ask the retailer that sold it, rather than inferring from the model name alone.
Does the same method work for checking a smartwatch or tablet?+
The general idea is similar — check that device's own settings for anything mentioning eSIM — but the menu and its limitations differ a good deal from a phone, so it is worth checking that device's own specific guidance instead.
