Country codes beginning with +87 are designated for global services, not specific to any single country. Here’s a breakdown:
- +870: Assigned to Inmarsat, primarily used for satellite phones, especially in maritime communications.
- +878: Allocated for Universal Personal Telecommunications (UPT), facilitating personal mobility across different networks and countries.
- +871 to +874: Previously used by Inmarsat for various services but have since been phased out.
- +875, +876, +877: Reserved for maritime mobile services, though not commonly in use.
- +879: Set aside for future non-commercial purposes.
These codes are part of the International Telecommunication Union (ITU) assignments for services that operate beyond national boundaries, such as satellite communication systems.
If you encounter a number starting with +87, it’s likely associated with one of these global services rather than a specific country.
