Comet SIM eSIM Data Plans for Bulgaria

Comet SIM does not offer an unlimited data eSIM for Bulgaria. The available options are fixed‑data plans that provide a specific amount of data for a set period. For example, Comet SIM sells a 20GB eSIM that is valid for 30 days, priced at $19.90 USD, and a 10GB eSIM also for 30 days, priced at $12.90 USD. Choosing a fixed data plan can be more cost‑effective for most travelers, unless a user requires very high data consumption beyond the limits offered.

Comet SIM does not provide any eSIM plans for Bulgaria that include a phone number or SMS capabilities. The available plans are data‑only, so travelers can use internet‑based services such as WhatsApp, Telegram or iMessage for calling and messaging. However, some destinations may block or restrict certain VoIP applications, so it is advisable to confirm that the preferred apps work in Bulgaria before proceeding with a purchase.

Comet SIM offers five single‑country plans and ten multi‑country plans that include Bulgaria. The available plans range in price from about $3.90 to $119.90 and provide data caps between 1 GB and 20 GB, with validity periods from 7 to 30 days. The single‑country options give you a dedicated data allowance for Bulgaria only, while the multi‑country plans allow the same data to be used across several destinations, offering greater flexibility for travelers who visit multiple countries.
