What is increment

Increment is amount of time in which the call will be billed. It is counted in seconds.

Example:

• Imagine call length is 15s
• Rate for 1 min is 1 EUR/min (for simplicity reasons)

Then:

• If increment is 1, then call length will be counted as 15s and call price will be 0.25 EUR (1/60*15) - increment is 1, so call can be 1, 2, 3... in length. 15s is exact length of call.
• If increment is 10, then call length will be counted as 20s and call price will be 0.333.. EUR (1/60*20) - increment is 10, so call can be 10, 20, 30... in length. 20s is nearest to 15.
• If increment is 20, then call length will be counted as 20s and call price will be 0.333.. EUR (1/60*20) - increment is 20, so call can be 20, 40, 60... in length. 20s is nearest to 15.

Most common increment is 60:

• If increment is 60, then call length will be counted as 60s and call price will be 1.0 EUR (1/60*60) - increment is 60, so call can be 60, 120, 180... in length. 60s is nearest to 15.

If call length is 55s the call will be billed in 60s anyway. If call length is 65s the call will be billed in 120s.

Increment can be from 1 till infinity (theoretically). Do not put it more then 120 if you understand what you are doing.
