Is international roaming free in Togo with my European or US SIM, or is Truly Roaming more cost-effective?

No, international roaming is definitely not free in Togo with most standard European (EU) or US SIM plans. Togo is outside these domestic roaming zones. Your home carrier (e.g., Orange FR, T-Mobile US, or Vodafone UK) will typically charge their highest 'Rest of World' international roaming rates, which can easily be $10-$15 per day. Truly Roaming offers a far more predictable and cost-effective solution, providing dedicated data packages that prevent bill shock and ensure reliable connectivity for your monthly stays.
