Photography: All photography requires a government permit. Taking photos of military sites, official buildings, and airports is strictly prohibited, even with a permit. Such sites are not always clearly marked. Film and cameras may be confiscated, often by undercover police.
Satellite Phones: Satellite phones are illegal in Chad and at the moment no permits are available. Travelers using satellite phones in Chad risk seizure of phones and possibly arrest.
Accessibility: While in Chad, individuals with disabilities may find accessibility and accommodation more challenging than what you find in the United States.
