RoameSIM eSIM Data Plans for China

RoameSIM does not provide a truly unlimited high‑speed data eSIM for China. The plans that carry the name “Unlimited” in their titles give a daily allowance of 3GB/day; once this limit is reached the data speed is reduced to 1000 kbps. Therefore, the data is capped, and the speed drops after the 3GB/day threshold.

For travelers who need a fixed amount of high‑speed data, RoameSIM offers several alternatives. For example, a plan that gives 20GB for 30 days costs $54.60 USD, and a larger 100GB plan valid for 180 days costs $124.60 USD. These plans would be more suitable for users who require a generous data allowance without the speed throttling that applies to the “Unlimited” options.

RoameSIM offers a range of China eSIM plans that include a phone number and SMS capability. The plans are priced from $21.00 USD to $124.60 USD and are valid from 7 days to 365 days. Each plan provides a +1 dialing code, inbound and outbound voice calls, and inbound and outbound SMS. Users should confirm any specific requirements directly with RoameSIM.

RoameSIM provides 12 single‑country data plans and 34 multi‑country data plans for China. Among these plans, 12 are structured with a daily data cap while the remaining 34 offer a fixed data amount. Prices span roughly from $2.40 to $208.60, and the data caps range between 200 MB and 100 GB, giving travelers flexible options for both short‑term stays and longer trips.
