Our pick for Bulgaria, and when unlimited overtakes per-gigabyte
For budget travelers the pricing dimension is the one to read: HelloRoam publishes an entry rate of $3.50/GB and scores 4.8/5 there, ahead of Holafly at 4.7/5. Plans in Bulgaria attach to Vivacom on 4G, A1 on 4G, and Telenor on 4G, with A1 Bulgaria and Yettel BG also on the published carrier list.

Holafly sells unlimited at $2.99/day, so a trip past 6 days costs more on the day rate than the 20GB rung costs outright at $17.03. One local detail the rubric does not score: One of the cheapest EU countries for mobile data.
