Is roaming free in Benin with my French or EU SIM card, or should I use SouthESIM?

Definitely not free, and this is where many travelers get caught out! Even though Benin is a French-speaking country, it is not part of the EU roaming zone or any French domestic plan. Most home carriers, whether it's Orange FR, T-Mobile US, or Vodafone UK, will charge you their highest 'Rest of World' international roaming rates, which can be incredibly expensive. SouthESIM offers a budget-friendly and transparent alternative, giving you clear data costs without any shocking bills upon your return.
