GulfData does not provide a truly unlimited high‑speed data eSIM for the United Kingdom. The plans that carry “Unlimited” in their name actually give 1 GB per day at full speed and then throttle the connection to 512 kbps once that daily allowance is reached.
For travelers who need a larger data budget, GulfData offers fixed data plans. For example, a 50 GB plan is available for 30 days at $34 USD, and a 50 GB plan for 180 days costs $56 USD. These fixed‑data options give a clear, time‑bound allowance that can be more cost‑effective for most users.
