Sim Card Options for Residents in Japan

Hi, I have an unlocked phone from the U.S. I want to buy a sim card with calling, sms, and data (wifi) services. So far I've found this plan from bmobile: http://www.bmobile.ne.jp/fd/index.html

I was wondering if anyone knew of any other better plans out there. I have a visa, and I do not want a new phone as my phone is already pretty new, so I just want a sim card. Thank you in advance.

unlocked phone yes but have you checked the compatibility ..?

what do you mean by better? cheaper?faster?more data limit?

you can checkout OCN mobile one, but no call . however can signup for +050, a VOIP system for phone call & receive.

you can try at Docomo better but expensive and
need a contract.

Thanks for your reply. Yes, I checked the compatibility and it looks ok. Here's the model of my phone: http://www.samsung.com/us/mobile/cell-phones/SGH-M919ZWATMB-specs

Frequencies and Data Type - LTE: Bands 1/2/4/5/7/17; HSPA+/UMTS: 850/AWS/1900/2100MHz; GSM: 850/900/1800/1900MHz

By better, I mean where can I get the best bang for my buck. So cheap, but with phone and sms services, and data plan of at least 3gb.
