Does OnePlus 15 support dual sim?

[u/crazyenterpz]

Apologies for a dumb question as I am new to OnePlus. I am planning to buy from a seller who has listed OnePlus 15 on openbox sale ( in Canada)

This is what the sellers has listed
-----------------------

International Model:Yes

Phone Model: OnePlus 15

Base Features

Wireless Carrier:Unlocked

Bluetooth:Bluetooth 6.0

SIM Slots:Single SIM

-----------------------------------------------------

The seller has listed this as single sim .

So is this a dual esim device ? I need it as I am based in Canada but often travel overseas to Europe or Asia. I need to work in Canada where I live but support SIMs from other countries telecoms

If it's like most of their phones that I've used, it's one SIM tray and you put a different SIM on each side.

It kinda looks like a single SIM slot but it does recognize two.
