MobiMatter does not provide an unlimited data eSIM for Bulgaria. All of its plans for the country have a defined data cap, such as the Bulgaria 100GB 6 Months plan, the Europe 60GB 15 days plan, the Europe and USA 60GB 60 days plan, the Half Global 60GB Yearly plan, and the Europe 50GB 60 days plan.
If a traveler needs a large amount of data, MobiMatter offers fixed data plans with substantial allowances. These plans can be more cost‑effective for most users, unless the traveler is an extremely heavy data consumer who would benefit from a truly unlimited option.
