Astaroam eSIM Data Plans for China

Astaroam does not offer a truly unlimited data eSIM for China. The plans that carry the “Unlimited” name provide a daily allowance of 3 GB; once that limit is reached the download speed drops to 1000 kbps, so the high‑speed data is not unlimited.

If you need a larger, non‑throttled data volume, Astaroam offers fixed‑data plans such as 50 GB for 90 days at $33.24 USD, 20 GB for 30 days at $10.59 USD, or 10 GB for 30 days at $7.44 USD. For travelers who expect to use a lot of data, these fixed‑plan options may be more cost effective than the “Unlimited” plans.

Astaroam does not provide China eSIM plans that include a local phone number or SMS capability. All plans available for China are data‑only, so travelers will need to rely on Internet‑based VoIP and messaging apps for phone calls and text messages. Popular services such as WhatsApp, Telegram, and iMessage can usually be used over the data connection, but users should verify that these apps are accessible in China before purchasing.

Astaroam offers one single‑country plan that is specific to China and 14 multi‑country plans that include China among their coverage areas. Plans are grouped into fixed data caps, which provide a set amount of data for the entire validity period, and daily data caps, where the data allowance is refreshed each day. Prices for these plans range from about $2.74 to $33.24, while the data limits span from 500 MB up to 50 GB and the validity can be as short as three days or as long as ninety days.
