From an iPhone
Open the Phone app, press and hold 0 until a + appears, then type 255 followed by the local Tanzania number. Or use Kinvo in Safari — no dialer permissions needed.
From Android
Open your Phone app, long-press 0 to get +, then dial +255 + the number. In Chrome, open kinvophone.com and call directly without touching your carrier plan.

Landlines don't have a + key, so use the full exit code: 011 255 then the local number. Check with your phone provider that international calling is enabled to avoid blocked calls.
How to Call Tanzania For Free
If the person you're calling in Tanzania has a smartphone with internet access, the cheapest way to call them is free: use WhatsApp, FaceTime, Telegram, Signal, or Google Meet. Both sides need the same app, and calls travel over the internet rather than the phone network — no per-minute fees, no country code needed.
For calling any regular Tanzania landline or mobile number — the kind that requires dialing +255 — there is no truly free option, because someone has to pay the termination fee to connect the call. Kinvo is the lowest-cost option for dialing Tanzania phone numbers, starting at $1.56/min with no subscription, compared to $1–$3/min at most US carrier rates.
