How much data per month can you get in China with an HK plan and tethering?
It all depends on your plan.
You can buy disposable 7, 14 or 30 days cards with different amount of China data in HK. There are places where you can get these at a big discount from face value, even more buying in quantities.
You need to qualify for an HK monthly plan if that is what you meant or want (residence status in HK with a verifiable HK address and an HK credit card or bank account for auto-payment). You need a plan with China data, not just HK data. China data is usually an add on to a basic plan.
My present plan has 20GB/month out of which 5GB can be used in China.
I carry with me two 7 days 1GB disposables in case I run out. These are from a different carrier than my main line.
I also have a Pokefi which can also give me HK access while in China.
When communication is mission-critical you need a spare for the spare.
