Compare eSIMs for Bulgaria 2026

Vivacom, A1 and Telenor are the Bulgarian networks named by the travel eSIM brands in this market, with Vivacom listed most widely. Bulgaria is therefore well served: the decision is less about finding a provider and more about choosing between packages that differ in size, duration and what happens after the included data is used. RedEx eSIM, AbestESIM, Roamix, MicroESIM, AirHub and iroamly have particularly full catalogues for Bulgaria, but their offers are not interchangeable just because the brands are familiar. Check the package against your trip, including whether topping up or buying another plan is possible when the allowance runs out.

Vivacom, A1 and Telenor are the Bulgarian operators named in provider listings for travel eSIMs. That gives you a choice of underlying network, but it is usually made indirectly: the eSIM provider’s published operator list determines which local network the eSIM uses. The provider you choose can therefore affect the network connection as well as the data allowance and terms. Check the operator pairing for the particular eSIM, since two products for Bulgaria may use different networks.

Yes, but only in a limited trial-like sense: a zero-priced data offer is listed for Bulgaria, although it provides a small allowance rather than enough data for a full trip. It is usually conditional on signing up with the provider and may be limited to one use per customer. That makes it useful for getting online briefly after arrival or checking that the service works, not as a substitute for a regular travel package.

Several providers list unlimited eSIM plans for Bulgaria, so this is a competitive part of the market rather than a one-plan exception. Unlimited refers to continued access, not unrestricted speed: a plan can run quickly for an initial allowance and then slow sharply, with some allowances renewing daily and others applying for the plan’s full validity. Once reduced, messaging may remain fine, but video, tethering and map loading can struggle. Check the reset schedule and the connection’s reduced speed before choosing.
