MobileSIM eSIM Data Plans for China

MobileSIM does not provide a truly unlimited data eSIM for China. All plans that include “Unlimited” in the name actually give 3GB of high‑speed data per day and switch to a reduced speed of 1000 kbps once that daily quota is reached. Consequently, the data allowance is capped, and the plan is not unlimited in the sense of providing continuous high‑speed connectivity without limits.

Instead, MobileSIM offers fixed‑data plans that give a larger total data pool over an extended period. For example, the China 20 GB plan for 30 days costs $40 and grants 20 GB of high‑speed data for the entire validity period. A similar option, the Asia 20 GB plan for 30 days, is available for $39 and includes coverage in China along with 17 other countries. Choosing one of these fixed‑data plans can be more cost‑effective if a user needs consistent data access throughout the trip.

MobileSIM does not provide an eSIM plan with a local phone number or SMS capability for China. Only data‑only eSIMs are available from this provider. Travelers can still make calls and send messages using VoIP applications such as WhatsApp, Telegram, or iMessage, which operate over the data connection.

MobileSIM offers twelve single‑country data plans that apply only to China, and an additional twenty‑two multi‑country plans that include China among their coverage. The single‑country plans provide data caps ranging from 200 MB up to 10 GB and are priced between about $1.50 and $31.00, while the multi‑country plans offer data limits between 20 GB and 100 GB and have prices that can reach up to $89.00. For users who need a plan that can be used in China and elsewhere, the multi‑country options are appropriate, whereas the single‑country plans provide a focused solution for travel within China alone.
