If the internet is working on the phone, then you should be able to go to any website such as google.com or yahoo.com or aol.com etc. on the phone.
Please test this: On your iPad, open Safari application, then go to the website www.aol.com on the iPad, then there, see if you are able to sign in your aol email address with your aol email password.
Please get back to me tomorrow to continue. Thank you for your patience.
