If you have a contract then your bill and therefore call history and call details should be held on record and may be accessible to you.
Before you register ensure that you have your post-paid cell phone at hand and you have a functioning and accessible email address. Upon successfully registering, where you'll need the email address, IDEA Mobile will send you a PIN (Personal Identification Number) to your mobile number via a text message or SMS (Short Message Service). Simply enter the pin number you received into the appropriate field on the website and you should gain access to your bill and hence call details. You can also wish to consider mail service, though this may incur a small charge.
In any case, it may be the wisest move to get in touch with IDEA Mobiles Customer Care department, who will be best placed to fulfill your requirements.
