A lot of phones sold by resellers sell phones as unlocked but they actually lock to the first SIM card inserted.

Does the model number of the device end in U or U1? This isn't always the the most reliable way to tell as the firmware can be changed, which has no impact on the SIM lock/unlock state. However, if it was sold new and unopened and ends in a U. All U models do SIM lock to the first pSIM or eSIM put in the device.
