Rufly does not provide a truly unlimited data eSIM for the United Kingdom. The plans that carry the word “Unlimited” in their name actually give 500MB per day at full speed, after which the speed drops to 5 Mbps. Examples of these plans are the United Kingdom Unlimited 7 days, United Kingdom Unlimited 15 days, and United Kingdom Unlimited 30 days, all priced at $13.43, $22.39, and $28.00 USD respectively.
These are fixed data plans, not pay‑as‑you‑go. Once the daily 500MB limit is reached, the speed is throttled, and after 30 GB, 45 GB, or 70 GB of total usage the speed is further reduced to 512 Kbps. Choosing a fixed data plan can be more cost‑effective for most travelers unless they are extremely heavy data users.
