Is roaming free in Sudan with my UK or US SIM card?

Unfortunately, no. Sudan is not part of any free roaming agreements with most international carriers, including those from the UK or US. If you use your home SIM card for data, calls, or texts in Sudan, you will likely face extremely high roaming charges, which can quickly add up and become very expensive. This is why a Cellesim eSIM is such a smart choice for travelers. It provides a cost-effective alternative, allowing you to enjoy reliable data connectivity through local networks like MTN Sudan in cities like Omdurman, without the worry of bill shock upon your return.
