Is roaming free in Cote d'Ivoire with my UK or US SIM card?

Unfortunately, no. Roaming in Cote d'Ivoire with a standard UK or US SIM card is generally not free and can be quite expensive. Unlike within the European Union where roaming charges have been abolished for EU citizens, countries in West Africa, including Cote d'Ivoire, are outside these agreements. Your home carrier will likely charge premium rates for data, calls, and texts while you're exploring Abidjan or other parts of the country. Opting for a Cellesim Cote d'Ivoire eSIM is a far more economical and convenient way to stay connected, avoiding those hefty unexpected bills.
