ASIMGO offers several unlimited data eSIM plans that cover Bulgaria. These plans range in validity from 1 day up to 90 days, with prices from about $1.18 to $48.38 USD. All unlimited plans are 5G and include tethering, but the speed may be throttled; the maximum speed is capped at 512kbps for most plans, while some have a higher cap of 10000kbps. ASIMGO applies a Fair Usage Policy, so speeds may be reduced after heavy usage, and travelers are encouraged to contact ASIMGO directly to confirm the typical amount of data that remains at normal speed before throttling occurs.
