SparkRoam eSIM Data Plans for United Kingdom

SparkRoam offers several unlimited data eSIM plans that cover the United Kingdom and a selection of other European countries. These plans are available in validity periods ranging from 3 days to 90 days, all delivered on 5G networks with a maximum speed of 10 Mbps. The unlimited data is subject to a Fair Usage Policy, so after heavy usage speeds may be reduced, and the maximum speed is capped as noted in the plan details. Travelers who need an unlimited data option for the UK can choose any of SparkRoam’s Europe (33) unlimited plans that suit their validity needs.

SparkRoam does not offer United Kingdom eSIM plans that include a phone number or SMS capability. Travelers can only purchase data‑only plans for the UK.

Without a local phone number, users can still make and receive calls and send messages through VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection. However, some destinations may block or restrict these services, so it is advisable to verify that the VoIP apps you rely on are accessible in the United Kingdom before purchasing a plan.

SparkRoam provides 8 single‑country plans that cover only the United Kingdom, and 34 multi‑country plans that include the UK as part of a broader European network. The single‑country options usually feature a fixed data amount for a set period, while the multi‑country plans often include a daily data cap that applies across all covered countries. Across both categories, prices vary from $1.34 to $178.25 and data caps range from 1 GB to unlimited, giving travelers a wide range of choices depending on usage needs.
