RoameSIM eSIM Data Plans for China

RoameSIM does not provide a truly unlimited high‑speed eSIM for China.
All plans marketed with “Unlimited” charge 3GB of high‑speed data per day; once the daily cap is reached the speed drops to 1000 kbps, so the data usage is still limited.

Travelers who need more data can opt for RoameSIM’s fixed data plans. For example, a 50GB plan is available for 90 days at $87.19 USD, and a larger 100GB plan is available for 180 days at $160.00 USD. These bundles give a consistent high‑speed data allowance and may be more economical for frequent data users.

RoameSIM does not provide a China eSIM that includes a phone number or SMS capability. Only data‑only plans are available for China. Travelers can still use internet‑based voice and messaging services such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations may block or restrict certain VoIP apps, so it is advisable to confirm that the apps you rely on are accessible in China before purchasing a plan.

RoameSIM offers 12 single‑country plans for China and 30 multi‑country plans that include China. The single‑country plans provide data caps ranging from 1 GB up to 20 GB, while the multi‑country selection can go up to 100 GB per plan. Prices vary from about $4.69 for the smallest daily‑cap package to roughly $182.81 for the largest fixed‑data‑cap plan. Daily data‑cap plans deliver a set amount each day during the validity period, whereas fixed‑data‑cap plans distribute the total data over the entire validity, which can be 3 to 365 days. Most plans allow tethering and impose a reduced speed limit of 1000.
