On getting a sim card in japan.

Well, my experience on this is limited to my own (obviously... or not?).

Basically I went to yodobashi camera. Then I went to phone section. Then this guy started helping out. Remember I declared that I don't know Japanese? well I did say that in one of my previous posts unless I'm wrong. So the guy knew english but couldn't speak it. And this was an opportunity to try to practice Japanese. So we both struggled to find the best plan for me! And we found... I actually forgot the provider name but I think it was "Freetel" or something similar sounding. The problem with this "Freetel" is that you need a japanese credit card to use it. So I tried to apply for a yodobashi credit card, but couldn't because I'm officially unemployed!
So we ended up looking for a new sim card. I was recommended Umobile. This can use a non-japanese credit card. I had an NZ visa debit so I could use it.

Now here is where I think the process differs from NZ. You actually buy the sim card first.
Yes, I had to pay >3000円 just to buy the sim card. After you buy the sim card. You have to register online. This is the place you put you card details in. Not at the shop, but online.

My plan is a... multiple rate plan. I pay <700円 if I use under 1GB and <1000 if I use <3GB.
Also I had to wait a few days for the sim card to actually start working. I think it was one day but I panicked for one day since it didn't immediately work. So if you can't make a password andor you sim card doesn't work immediately. Just worry for a few days and it might fix itself if it's the same thing as what happened to me.

I heard someone else got a plan too.
His phone isn't compatible with the sim card here (in Japan), so he had to buy a new phone. He was lucky because there was a promotion at that time with "y mobile" I think. So he pays like... 30,000 or 40,000円 per month for 6GB of data (presumably per month) and idk how many minutes of calling and an iphone 5. I think I heard the contract was like 2 years, which is too long for me.

My plan is a data only plan since I prolly won't text or call. Or maybe I just need to make moar friends...
