Astaroam eSIM Data Plans for United Kingdom

Astaroam does not provide an unlimited‑data eSIM for the United Kingdom. All of its UK offerings list a specific data cap, such as 1GB, 3GB per day, 2GB per day, 20GB, or 50GB for a set validity period. After the stated allowance is used, the speed is reduced to 1000 kbps.

Instead, travelers can select from Astaroam’s fixed data plans that offer large high‑speed data volumes—examples include the 50GB plan valid for 30 days or the 20GB plan valid for 30 days. For most users, these high‑cap fixed plans can be more cost‑effective than continuously topping up a pay‑as‑you‑go balance.

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 provides 32 single‑country data plans and 31 multi‑country plans for travelers visiting the United Kingdom. The available plans cover data caps ranging from 1 GB to 50 GB and are priced between $0.93 and $43.49. Astaroam offers both fixed data cap plans, where the data amount is set for the entire validity period, and daily data cap plans, where the data allowance resets each day.
