3 Hong KongAvis 

I signed a two-year contract with an expensive plan that included data coverage across Asia, specifically because I travel frequently. However, during a recent short trip abroad, my mobile internet did not work at all. This completely defeated the purpose of the plan I had purchased.

Instead of resolving the issue efficiently, the staff asked me to visit the store multiple times (at least 4–5 visits), which was extremely frustrating and time-consuming. Even after all these visits, the problem was not properly addressed.

The level of service was highly unprofessional, and the overall experience felt misleading. I previously used another SIM card provider in Hong Kong for over four years and never encountered anything close to this level of inconvenience, everything worked smoothly there.

I strongly do not recommend this provider based on my experience.

The base cost is already not great. The app is a terrible website packaged as an app full of ads.

I almost always get charged more than my monthly amount. Some months I get charged 800-900HKD just for making 2-3 quick phone calls outside Hong Kong.

I have Data Roaming off, and Allow Mobile Data Switching off and use a **different SIM card** for data and yet they still charged me 467HKD for a single day "roaming" -- WITH THESE THINGS OFF and using a completely different provider for data. Leaving the house in a foreign country even if you have roaming off they charge you. Absolute crooks!

Bought a mobile service plan only to discover that the sales staff mid advised me , certain features eating up data and adding hidden cost were not pointed out and now i am stuck in a contract i can’t change. The sales practise of 3 H is deceptive and advise not to use them.!
