Your region is also a significant factor in getting updates. It dictates when the update will be available to you. Sooner or later, every supported region receives the update, but the date differs from country to country.

If you see someone in another country testing the new update, but your iPhone can't find it, be patient. It will arrive. When the latest update is released, you can find information online on when it will be available in your region.
