Simsima for United Kingdom FAQ
Does Simsima offer unlimited data eSIM for United Kingdom?
Simsima does not provide a true unlimited data eSIM for the United Kingdom. While several plans are labeled “Unlimited, ” each includes a cap of 3 GB per day; once this 3 GB daily limit is reached, the speed is reduced to 1000 kbps.
If unlimited high‑speed data is required, Simsima offers fixed‑data alternatives such as the 100 GB plan valid for 180 days or the 50 GB plan valid for 30 days. These plans give a large amount of high‑speed data without daily capping and can be more cost‑effective for frequent travellers.
