Is roaming free in Iceland for UK or US SIM card users, and why choose WestESIM instead?

No, roaming in Iceland is generally not free and can incur significant charges, often surprising travelers. For UK visitors, most carriers like O2 or Three have reintroduced daily roaming fees (e.g., £2-£6) post-Brexit. US, Canadian, or Asian travelers using major carriers such as AT&T or Rogers will likely face expensive international day passes ($10-$15) or exorbitant per-MB rates. WestESIM offers a much more cost-effective and predictable solution, providing high-speed data across Iceland without the worry of unexpected roaming bills, ensuring you stay connected affordably.
