No, roaming in Iraq with an EU, UK, or US mobile plan is generally not free and typically incurs high costs. Iraq is not part of the European Union's "Roam Like At Home" zone, so EU plans will treat it as an out-of-bundle destination. Similarly, UK and US mobile providers do not include Iraq in their standard roaming packages, leading to significant pay-as-you-go rates for data, calls, and texts.
Expect to pay premium rates per megabyte for data usage, which can quickly become very expensive. To avoid bill shock and stay connected affordably, consider using an eSIM for your trip. An eSIM provides local data connectivity by automatically connecting to the strongest available major network in areas like Baghdad, Erbil, and Basra, offering a much more cost-effective solution than traditional international roaming.
