Roaming Zone Memberships
The six Gulf Cooperation Council states — Saudi Arabia, UAE, Kuwait, Qatar, Bahrain and Oman — have progressively reduced roaming charges since 2012. Roaming price caps were implemented in phases, with significant reductions (up to 40%) starting April 2018. By 2021, charges within the GCC were largely eliminated for voice, SMS and data, though some operators still offer bundled roaming packages rather than truly free roaming.
