ZenSim’s eSIM products for the United Kingdom do not provide true unlimited high‑speed data. The plans that use the name “Unlimited” actually give a 3GB/day cap; after that limit the speed may be reduced, though a specific throttled rate is not listed.
Travelers who need larger data allowances can choose from ZenSim’s fixed‑data plans, such as the 40GB plan valid for 30 days at $51.00 USD or the 20GB plan valid for 15 days at $26.00 USD. These fixed plans can be more cost‑effective for most users unless continuous, unrestricted usage is required.
ZenSim does not offer United Kingdom eSIM plans that include a local phone number or SMS capability. All United Kingdom eSIM plans from ZenSim are data‑only and do not support inbound or outbound calls or text messaging. Travelers can still use VoIP and messaging apps such as WhatsApp, Telegram, or iMessage over the data connection.
ZenSim offers a total of 13 single‑country plans and 13 multi‑country plans that cover the United Kingdom. Within these options, six plans feature a daily data cap allowing a uniform amount of data each day, while twenty offer a fixed data cap that provides a set amount of data for the entire validity period. The available UK plans span a price range from roughly five dollars to sixty‑nine dollars, with data limits between one gigabyte and forty gigabytes.
