Prepaid sim card with data

I am shortly be spending 3 months in France from May to July (visiting from Australia). I have been trying to find my way through the offers from the various telecommunication companies. Instead of coming up with solution, I have become overwhelmed and confused.

I have an unlocked Android smartphone. I don't have a bank account in France so I understand from previous visits to France that I am limited to buying prepaid sim cards. I want to be able to access emails (gmail) and surf the internet. I would appreciate your recommendations for any prepaid sim cards that either include or I can add internet (data) access to. I estimate I would need about 1 GB per month. Any help or advice greatly appreciated. The Option Internet Max that I previously purchased when using Mobicarte seems to no longer authorised to use with Mobicarte.
