eSIMatrix does not offer an unlimited data eSIM for the United Kingdom. The only plans listed for the United Kingdom and its neighboring countries provide a fixed data allowance of 20 GB. For example, the United Kingdom 20 GB – 30 days plan is available for $17.00 USD and the Europe 20 GB – 30 days plan, which includes United Kingdom coverage, costs $24.00 USD. These plans deliver 5 G connectivity and are valid for 30 days. For travelers who expect to use large amounts of data but do not require truly unlimited usage, a fixed‑data plan can be more cost effective unless the user is an extremely heavy data consumer.
