Yes, Yoho Mobile sells unlimited data eSIM plans for China. The plans range in validity from 1 day up to 30 days, with prices starting at $2.28 USD for a 1‑day plan and going up to about $103.61 USD for a 30‑day plan. All unlimited plans have the same feature set: tethering is allowed, the maximum speed is capped at 5000 kbps, and speeds may be reduced at the provider’s discretion.
Typical usage is subject to a Fair Usage Policy; if data consumption is very high, Yoho Mobile may throttle speeds to a lower rate. If you need confirmation on whether a Fair Usage Policy applies to a particular plan or the amount of data that can be used at normal speed, it is wise to contact Yoho Mobile directly for clarification.
