CloudOn eSIM eSIM Data Plans for Bulgaria

CloudOn eSIM does not provide a truly unlimited data plan for Bulgaria. The plans labeled “unlimited” give a fixed daily data allowance—either 2GB/day or 5GB/day—at high speed, after which the speed drops to 1 Mbps. For example, the Europe Unlimited – 3 days plan offers 5GB/day for 3 days before throttling to 1 Mbps.

If a traveler prefers an unthrottled, larger data allotment, CloudOn eSIM offers fixed data plans such as Bulgaria 50 GB 30 days, which grants 50 GB for 30 days, or Bulgaria 20 GB 30 days, which provides 20 GB for the same period. These fixed plans do not include a speed reduction after the data allowance is used.

CloudOn eSIM does not offer any Bulgaria eSIM plans that include a phone number or SMS functionality. The available Bulgaria plans are data‑only, so travelers cannot receive or make standard voice calls or SMS messages through the network.

Users who need messaging or voice capability can rely on VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict access to these services, so it is advisable for travelers to confirm that their preferred apps work in Bulgaria before purchasing a plan.

These ranges give a broad overview of what travelers can expect when choosing a CloudOn eSIM for use in Bulgaria.
