Hi all. I left HK in 2013 without canceling my mobile postpaid contract (I left in a haste so didn't have time to close it). I guess I had a few months left on the contract, so I would have probably owed around HKD 500 or so. Anyway, I didn't think much about this until recently when a friend told me that if you don't honor contracts, the operator would ask a collection agency to recover the money and if the agency cannot recover the money, they would blacklist you. (Also FYI, I had had a similar issue earlier when I broke my 3 Mobile contract and didn't pay around HKD 300 for a few months before I got a legal notice and then I paid up eventually).
Since then, I have been to HK numerous times over the years and have had no issue visiting as a tourist. My question is: if I ever move back to HK, would my past record regarding not honoring my contract be an issue? Also, is it possible that the HK govt might share this data with other countries? I hope to apply for a UK residency in the future and don't want a stupid mistake I made a long time ago affect my application.
Maybe I'm completely overthinking this, but would love to hear some thoughts.
