It's 350MB for 7 days and 700MB for 14 days.

Best bet is to get a Telkomsel SIM once you arrive in Bali. You can buy them almost anywhere and the person selling it to you will be able to activate it and set you up on a data plan. Just tell them you want 2 or 3 GB, the offers change frequently but you should be all up and running for around about Rp. 100.000 and have enough data to last you, providing you aren't planning on watching heaps of YouTube videos or anything like that.
