I am a meo customer. I use a SIM with a plan. Earlier, my bill was 31 euros, but this time my bill has come up a lot. So I want to know why my bill came up so high this time.

How long have you been a customer? Which part of your bill has increased? Perhaps your loyalty period has ended, meaning the discount you were receiving has also come to an end. Please check the loyalty period on your bill, under "informação adicional".
