Dialing Tips
- Remove the leading zero: When dialing internationally, drop the trunk prefix (usually 0) that is used for domestic calls in Tanzania.
- Use the + notation: From a US mobile phone, use
+255instead of011 255. - Verify the number length: Make sure you have the correct number of digits. If your call does not connect, check whether you need to add or remove an area code digit.
- Save contacts in international format: Always store phone numbers with the full
+255prefix so they work from any country.
