Long story -
Late last year I purchased a used Google Pixel in the US from eBay. I used it on Skinny for a couple of months without issue then got tempted by the Pixel 2 XL so bought one of those and sold the Pixel on TradeMe in November.
I just got an email from the buyer today saying the phone has been IMEI blacklisted. Which puts me at a bit of a loss.
I haven't blocked it and I assume the buyer hasn't either. I didn't show the IMEI number on TradeMe so assume only myself and the buyer know the IMEI number - in any event it seems like the 'blacklister' would need to prove they own the phone first.
I have flicked a message to the eBay seller on the off-chance but from what I have read from the TCF webpage IMEI blocks are country specific. So even in the event he blacklisted the phone it would only be in the US not NZ?
What can I do to sort this out. Do I just tell the buyer to call their telco or is there some further action I need to take?
Thanks in advance for any advice.
TL:DR - Phone I sold has been blacklisted not sure why and don't know how to fix it :(
