    Speed was very low where I was mostly using it (in Ap Lei Chau in Hong Kong). Could only use ~1GB (out of 20) in one week due to the low speed. Maybe it works in other locations but for me it was not great. Other mobile networks (Three HK) in my location are pretty fast so I suspect the issue was the provider.

      Hi Tai, sorry to hear you experienced this issue. We haven’t heard issues from other customers regarding China Mobile. Coverage in Ap Lei Chau could’ve been spotty due to being by the water on the South Side.
