Why an eSIM is Recommended for the United Kingdom

Brexit Changed Everything: No More Free EU Roaming!

IMPORTANT: Since Brexit (January 1, 2021), free EU roaming no longer applies to the United Kingdom! Each European carrier has defined its own UK policy:

Orange: sometimes includes the UK in its Europe Zone 1 roaming, but with limited quotas depending on the plan
SFR: may charge additional fees ($3-10/day) on entry-level plans
Bouygues Telecom: policy varies depending on your plan subscription date
Free: generally includes the UK only on the 19.99€ plan (not on the 2€ plan)

Roaming charges can be expensive depending on your plan. To avoid unpleasant surprises, an eSIM starting at $1.60 represents the safest and most economical solution.
