Can someone provide tips on getting a sim card for 7 days in Bali, mostly for internet on my iphone

We just came back from Bali 8 days trip. Quite fun. A lot of people promote their drivers. Before i say something about ours.
Does your driver?
1) Help you on bargaining?
2) Under table entrance fees, pay 1, 4 ppl went in ?
3) Bali has like small toll where villager collect fees, does he able to skip all that for u?
4) Historical explanation like a pure tour guide of places.?
5) Help you get cheaper Simpati Sim card ? some ppl here asked me to get from airport lmao,that cost like double/triple.
6) Take care of your kids.
7) Help you carry stuff
8) Shoot great photo

Well, thank godness ours has all the above.
