Description
Thirr is an eSIM provider based in Prishtina, Kosovo, offering data plans for travel including Europe, Balkans, UAE, Canada, Peru and more. Plans offer unlimited options with durations from 3 to 30 days, but users often report throttling after 7-30GB, unstable connections outside promised 5G, and refund difficulties despite customer service via WhatsApp. Ideal for budget travelers seeking simplicity, but use with caution due to mixed reviews on network reliability.
