Best Mobile Plans Under HK$100 in Hong Kong
The HK$100 line is where Hong Kong's budget plans cluster — MVNOs and operator sub-brands fight here with speed-capped but generous data. Check the fine print on throttled speeds, and remember prepaid cards often work out cheaper per GB than contracts at this price point.

Frequently asked questions
Are sub-HK$100 plans speed-capped?
Many are — sub-brand monthly packs commonly cap around 21–42Mbps, which is still ample for streaming and hotspot use. Plans without caps at this price usually trade data volume instead.
