Yettel Bulgaria and travel eSIM in Bulgaria
Yettel Bulgaria is one of the networks your eSIM may use in Bulgaria. Here is who actually decides which network you get, and what to do with that.
Author: Porsch Kunnipat Siramanakul · Co-founderReviewed by: Bob Kanokphon Thongdee
Quick answer
- Yettel Bulgaria runs 4G and LTE and 5G in Bulgaria.
- Travel plans connect by roaming, so no plan can promise one specific network.
Yettel Bulgaria in brief
Yettel Bulgaria is a mobile network operator in Bulgaria, and one of the networks a travel eSIM may reach through roaming.
We are not a reseller for this operator and we have not run our own field speed tests. The band and network details below come from the sources listed at the end of the page.
Who licenses Yettel Bulgaria
Mobile networks in Bulgaria are licensed, and their spectrum assigned, by the Communications Regulation Commission (CRC). The bands above are the ones it allocates. A problem with the local network's own service goes to the operator first; a problem with your eSIM plan comes to us.
Why plans do not name a fixed network
Nearly every travel eSIM is a roaming product: the profile picks a network by an order the supplier sets, not by the buyer. If Yettel Bulgaria is weak where you are, try selecting A1 Bulgaria or Vivacom manually in the network settings, and keep data roaming on for the eSIM profile.
FAQ
Will my eSIM definitely connect to Yettel Bulgaria?+
Travel plans run over roaming agreements, so the network depends on the supplier behind the plan, your device and where you are.
Does Yettel Bulgaria run 5G, and will my plan get it?+
We could not confirm Yettel Bulgaria's 5G status from an official source. Our plans that reach this network list 4G and LTE and 5G.
How do I see which network I am on?+
Check the carrier name at the top of the screen, or open the mobile-network settings and look at the operator list. If signal is poor, try selecting a network manually instead of automatic, but only one your plan actually supports.
