ChillaxSIM eSIM Data Plans for United Kingdom

ChillaxSIM does not provide a truly unlimited data eSIM for the United Kingdom. Every plan that carries the “Unlimited” label actually limits high‑speed data to 1 GB per day, and once that cap is reached the speed drops to a throttled rate—commonly 5 000 kbps, and in some cases 128 kbps after the allowance is exhausted.

If a traveler needs a larger data quota without the daily restriction, ChillaxSIM offers fixed‑data plans that are more cost‑effective for heavier usage. For example, a 30 GB plan is available for 30 days, a 60 GB plan for 30 days, and a 150 GB plan for 30 days, all of which give full speed until the data cap is reached and then apply the same throttling rules as the “Unlimited” plans.

ChillaxSIM does provide United Kingdom eSIM plans that include a UK phone number and full SMS capability. The available plans range from 1 GB to 150 GB of data, with validity periods of 15 days to 30 days, and prices from $14.90 USD to $32.90 USD for the larger data packages. All United Kingdom plans use the dialing code +44 and support inbound and outbound voice calls as well as inbound and outbound SMS. Users who need a specific function—such as a certain amount of international minutes—are advised to confirm the details directly with ChillaxSIM.

ChillaxSIM offers 30 single‑country data plans and 15 multi‑country data plans for the United Kingdom. The plans range in price from about $2.85 up to $108.34 and vary in data limits between 1 GB and 150 GB. Some of the offerings feature fixed data amounts per month, while others provide daily data caps that reset each day, giving travelers flexibility depending on their usage patterns. The provider also offers a subset of plans that allow tethering, with certain thresholds for reduced speeds (128 kbps, 5 000 kbps, 10 000 kbps) in case of network congestion.
