If I choose an annual plan with monthly payments, you may have some tially during the year? Or the same monthly amount duarante a year?
I don't understand the question... what do "tially" and "duarante" mean?
The value of the annual plan with monthly payments, may have adjustments during the year, and this figure does not change?
The amount you pay should stay the same throughout the year, if that is what you are asking?
