Re: anyone or only the account owner can return modem to them? went there today.
wrote everything maybe needed on a paper (included the 4 digi pin number), but she asked nothing, gave me a receipt to sign(for them to keep), gave me another one she signed(for me to keep), done.
the receipt only have the returned modem MAC, doesn't have the self-own one.
i was a little worry when i saw there is a sign saying something like "valid ID is required for all equipments", maybe that's only for getting equipments from there, not returning.
