Astaroam eSIM Data Plans for United Kingdom

Astaroam does not provide a truly unlimited high‑speed data plan for the United Kingdom. The plans marketed as “Unlimited” actually allow 3GB per day (or 2GB per day in the UK‑specific variants); once the daily allowance is reached, the speed is throttled to 1000kbps.

Instead, Astaroam offers fixed‑data eSIMs that may be more cost effective for heavy users. For example, a 50GB plan valid for 30 days costs $24.79 USD, and a 20GB plan for 30 days costs $7.64 USD. These plans provide a set amount of high‑speed data without the daily throttling that applies to the “Unlimited” names.

Astaroam does not provide United Kingdom eSIM plans that include a phone number or SMS capability. Only data‑only plans are available for this destination.

Travelers who need messaging or voice functionality can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but this is not guaranteed because some destinations may block or restrict particular services. It is advisable to verify that the required apps are accessible in the United Kingdom before purchasing a plan.

Astaroam offers 32 single‑country plans and 23 multi‑country plans that cover the United Kingdom, providing a broad spectrum of options for travelers. The available packages range from about $2.00 to $44.21, with data caps spanning from 1 GB to 50 GB and validity periods that can last anywhere from 3 to 180 days. Within these offerings, there are 16 plans with a daily data cap and 39 fixed‑data‑cap options, allowing users to pick a model that best fits their usage pattern.
