Will my EU or UK-based SIM card incur roaming fees when operating DataESIM in Bosnia and Herzegovina?

When utilizing DataESIM in Bosnia and Herzegovina, your primary EU or UK SIM card will be subject to its carrier's standard international roaming charges. Bosnia and Herzegovina is not a member of the European Union, therefore the "Roam Like at Home" regulation does not apply. Major EU and UK carriers, such as O2 UK, Vodafone DE, or EE, will classify data usage in Bosnia as out-of-bundle roaming, resulting in substantial per-MB costs. DataESIM offers a predictable, high-data alternative, ensuring cost-effective and robust connectivity in locations like Sarajevo or Mostar without unexpected bills.
