Hello, I have a Mikrotik RouterBOARD groove-A52hpn, but in the box there
Tell me if it's USA or International, just say EU and other things,
Is there any way to know, either by serial number or
MAC address?, and if it's USA, it could be unlocked,
greetings and happy day,
Alberto

If there is no -US at the product code end, it should be International version.

Older devices didn't have US lock. Just make sure it has no "US" in the product code or on the sticker.

Looks like I'm stealing the topic but I really wanted to find this one out: is it possible to send the device back to get it unlocked/changed from US to international.
Here's my situation.
I'm currently in Canada, where I have purchased:

• hAP ac (international version: RB962UiGS-5HacT2HnT)
• wAP ac (US version: RBwAPG-5HacT2HnD-US - vendor did not have the international one anymore)

I'll be moving to Europe in a few months.
So my question is, can I send the wAP ac device back to have it unlocked by manufacturer service when I'm already in Europe? How would I go about that, if that's even possible?

There is nothing like that offered by anyone. Maybe because the special restrictions are applied in some more complicated way than would be in case of lockpack was applied. What about the selling the US device there and buying international version (of better device?) in Europe after that?
