Is my SouthESIM plan for Hungary also valid in neighboring non-EU countries such as <strong>Serbia</strong> or <strong>Ukraine</strong>?

That's an excellent question for those planning a broader Eastern European adventure! This specific SouthESIM plan is designed for use within Hungary and the EU. If your journey takes you beyond the EU borders, for instance, by train from Budapest to Belgrade (Serbia) or towards Ukraine, your data connection will cease. For seamless travel across multiple countries, especially those outside the EU, we highly recommend exploring SouthESIM's regional or global bundles, which offer continuous coverage across diverse destinations.
