MobileSIM eSIM Data Plans for China

MobileSIM does not provide a truly unlimited eSIM plan for China. The plans that carry the word “Unlimited” in their name actually allow 3 GB per day with a reduced speed of 1000 kbps once the daily limit is reached, which means the high‑speed data is capped.

Instead, MobileSIM offers fixed data plans that may be more cost‑effective for many travelers. For example, a China 20 GB for 30 days plan is priced at $40.00 USD, and an Asia 100 GB for 180 days plan covers China plus 17 other countries for $185.00 USD. These alternatives provide larger data allowances without speed throttling during the validity period.

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 a total of 25 data‑only plans that could be used in China—12 single‑country plans that cover China exclusively, and 13 multi‑country plans where China is an included destination. Some of these plans are fixed‑data‑cap offers, while a smaller subset (six plans) provide daily data caps that reset each day. Pricing on the site ranges roughly from $4.00 to $185.00, with data limits spanning from 1 GB up to 100 GB. The plans vary in validity from three days to six months, and in certain cases the speed may be capped to 1 Gbps.
