Inquiry Regarding Higher Billing Amounts for Mobile Plans


I have two mobile SIM card contracts (numbers: +XXXXXX and +XXXXXX), each with a plan costing around 19.99 or 20 euros. However, for the last three months, I have been receiving bills of over 40, 72, and 39 euros for each SIM card, respectively. Could you please clarify why the billed amounts are higher than expected? Thank you.

You can find the explanation on pages 2 and 3 of the invoice.

Hello @karthick0218 ,

welcome to the o2 Community 💙.

Having a varying sum across several bills could have plenty of different reasions. As Bumer already wrote, you can always check your bills for a more clear picture of what you were billed for. Did you maybe spend some time out of country or called a foreign number. That could lead to a sudden increase of the bill for a single month.


Kind regards, Sven

There are many possible reasons. Have a look at page 2 of your invoice for the answer.

Hello @Anju Chettayil Padmanabhan,

welcome to the o2 community.😊

Such an unexpected amount is not great, that is understandable. Following bs0's advice, have you already taken a closer look at your bill and been able to see what it was? 

Kind regards, Lea
