The plans marketed as “Unlimited” give a 3GB/day allowance, and once that daily limit is reached the speed is reduced to 1000kbps. For travelers who need more data, MobileSIM offers fixed‑data plans such as a 5GB/30‑day plan at $27.50 or a 10GB/30‑day plan at $57.00. Choosing a fixed data plan can be more cost effective for users who consume a lot of data.
