Unlike many competitor plans that limit roaming to Europe or charge extra fees, this SIM includes regions like the Middle East, South Asia, Europe, and parts of the Americas in a single fixed monthly plan.
It is especially popular among UK-based businesses that frequently travel to UAE, Saudi Arabia, Pakistan, and European countries.

Yes, this SIM includes full roaming support in major Middle Eastern business hubs such as:
- United Arab Emirates (UAE)
- Saudi Arabia

- Google Maps navigation during travel
Once the 12GB limit is exceeded, additional roaming charges may apply depending on the carrier policy.
