TooSim eSIM Data Plans for United Kingdom

TooSim does not provide any unlimited data eSIM plans for the United Kingdom. All of their country‑specific offers are capped at 10GB, 20GB, or 50GB for a validity of 30 days.

Customers needing larger data allowances can opt for one of these fixed plans, such as the United Kingdom 50GB plan priced at $47.99 USD or the 20GB plan at $21.99 USD. These plans allow tethering and keep the user connected to the UK network. Fixed data plans are usually more cost‑effective than purchasing data in excess of the required amount, unless one is an exceptionally heavy data consumer.

TooSim does not offer United Kingdom eSIM plans that include a local phone number or SMS capability. The provider supplies only data‑only eSIMs for travel to the United Kingdom, with no inbound or outbound voice or text messaging services.

Travelers can still communicate through internet‑based applications such as WhatsApp, Telegram, or iMessage over the data connection provided by the eSIM.

TooSim provides seven single‑country data plans for the United Kingdom and another seven multi‑country plans that include the UK as part of their coverage. For both categories the prices start at $3.99 and go up to $60.99, while the data allowances range from 1 GB to 50 GB and validity periods span 7 to 30 days. The plans also allow tethering where applicable.
