Zwitchy does not provide a plan that offers truly unlimited high‑speed data to Afghanistan. The plans labeled “Unlimited” give a daily allowance of 1 GB and after that limit is reached the speed is reduced to 1000 kbps; the data amount is a hard cap, not an open‑ended allocation.
If you need a larger data allowance, Zwitchy offers fixed‑data plans such as the 30 GB for 30 days plan at $64.50 USD or the 50 GB for 30 days plan at $106.00 USD. These plans allow you to use the full data amount at normal speed for the entire validity period.
