I am traveling to HK & Japan in January 2012. So I want to get a SIM card for use in both HK & Japan, but as we all in this forum know, foreigners can't purchase SIM cards in Japan.

So when looking at carriers for HK, I came across 3 and their prepaid SIMs, which also allows a "Data Daily Roaming Pass" in other countries. Most importantly, Japan for just $168 HK ($21 USD) per day for unlimited data usage according to their Data Daily Roaming Pass website.

The rate is very reasonable, and comparable to other SIM/phone rental options.

The only hitch is that you would have to purchase a 3 SIM from eBay before traveling to Japan.

So now I am looking into purchasing a prepaid 3 SIM from eBay before I travel to HK & Japan, and am wondering if this eBay seller's SIM can be activated with the Data Daily Roaming Pass option?

Thanks.
