eSIM eSIM4Travel pour Bulgaria en 2026

Telenor and Vivacom are the operators eSIM4Travel lists for Bulgaria, giving a fallback when one is thin outside the cities. Its catalogue has a large range, so choosing the right data size matters more than finding a plan at all; the risk is buying more than a fortnight needs. eSIM4Travel lists technology up to 5G, but does not say where traffic breaks out, so delay to Bulgarian services and the apparent IP location are unknown. Top-up is supported, allowing an exhausted plan to be extended rather than rebought.
