TooSim eSIM Data Plans for United Kingdom

TooSim does not provide an unlimited data eSIM for the United Kingdom. All of the United Kingdom plans listed have explicit data caps and a 30‑day validity period. Available bundles include 10GB for $12.99, 20GB for $21.99, and 50GB for $47.99, each valid for 30 days.

These fixed‑data plans offer a clear price‑to‑data ratio for travelers who do not require an unlimited data allowance. They are generally more cost‑effective for typical usage, while still accommodating higher data needs through the 50GB option.

TooSim does not provide United Kingdom eSIM plans that include a phone number or SMS capability. The provider only offers data‑only eSIMs for travel. Travelers who need messaging or calling functionality can use VoIP applications like WhatsApp, Telegram, or iMessage over the data connection. Some destinations, however, may restrict or block access to specific apps or VoIP services, so users should verify that their preferred apps are available in the United Kingdom before purchasing an 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.
