There have bee a number questions about mobile phones, WiFi & walkie-talkies in various threads, so I thought I'd start a definitive guide and sticky it!
First a few details.
Mobile Phones.
Japan uses 3G and LTE(4G). 3G is mostly restricted to 2100Mhz, which pretty much all 3G phones support. (there are also a few other frequencies that are not used in Australia, such as 900MHz, 1500MHz & 1700Mhz)
GSM does not work in Japan
If you intend to use your Aussie phone or smartphone, you need to either have it unlocked, or you will roam instead. Be aware that if you roam with data, you will probably get an huge bill. Put it in "aeroplane mode" if you intend to roam.
Walkie Talkies.
Aussie walkie-talkies use different frequencies to Japan, and if you use them and get caught, you will incur a large fine.
WiFi.
Free WiFi hotspots are not common, except around JR stations, and places like Starbucks & McDonalds. Hotel lobby free WiFi is however, common. You can get paid WiFi
SIMs for you Aussie phone
Japan has two types of Prepaid SIMs you can buy:
1. Data only (available from DoCoMo, via B-mobile) These are SIM only.
2. Voice only (available from Softbank). These are available as both SIM or SIM & phone
You can also rent phones, which will give you more options, but cost you more if you're in Japan longer than just a week or two.
Paid WiFi
These are available as either WiMax or LTE WiFi devices.
1. WiMax uses a wideband WiFi network, but is only available in big cities and along SOME expressways. For snow resorts, this is not a good option.
2. LTE. Previously, E-Mobile had both 3G & LTE devices, but now only LTE is available, so for the moment, the coverage area is not as good as it used to be.
Generally, you can connect 5-20 devices.
In either case, it's a good idea to check CAREFULLY the coverage areas. In both cases, tourists can only rent these devices. These are useful if you only want to use data in a central location for a number of people in your group.
