Calling outside Namibia
You can use public phones for direct international calls. Buy Telecards in different denominations from post offices and telecom offices.
There's cell-phone reception in all major towns. Enable your own for international roaming before you leave home, or buy a local SIM card when you arrive (a much cheaper option, and very easy to do). The two major cell networks are MTC, and the newer (government-owned) TN Mobile. A SIM card will cost around N$10–N$20, and the prepaid rate varies from about N$1–N$3 per minute. Airtime is available in most supermarkets, convenience stores, and some bookshops.
