AlpineSIM does not provide a truly unlimited high‑speed data eSIM for Bulgaria. The plans that carry the word “Unlimited” in their name are actually capped at a fixed amount of high‑speed data – for example, 500 MB, 1 GB, 2 GB, 3 GB, 5 GB or 10 GB – and they may throttle the speed once the limit is reached.
Travelers who need more data can choose from AlpineSIM’s fixed‑data eSIM options that cover the whole country. For instance, a 10 GB plan costs about $5.43 for one day, a 5 GB plan costs about $2.72 for one day, a 3 GB plan costs about $2.25 for one day, and a 2 GB plan costs about $1.34 for one day. Selecting a fixed‑data plan can be more cost‑effective for most users compared to attempts to use an “unlimited” label that actually limits usage.
AlpineSIM does not provide a Bulgarian eSIM that includes a phone number or SMS capability. The provider only offers data‑only plans for Bulgaria. Travelers can use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice and messaging.
