With the new plan, 1 GB valid for 30 days can be purchased for ¥3,100. This is much more appropriate given how we realistically use smartphones. For an extra ¥1,000 per month, I can increase my quota by four times.
Right now, you cannot buy a FAIR SIM with a 30 day validity period. The only option is the standard FAIR with a 120 day period. Once that first amount is used, when you recharge the SIM, you can either select 30 or 120 days.
The 1 GB/month data service plan will be available from September 1 at 6 pm for current FAIR customers.
Update: A FAIR SIM can be converted to a 1GB Flat Rate, and then back to a FAIR data plan. The expiration date after which the SIM can no longer be charged depends on the last data plan. If a FAIR is purchased and the initial charge consumed, you have 60 days to recharge. if on the 59th day, a 1 GB Flat Rate charge is added, you will then have 10 days to recharge once the second charge expires. If the third charge is back to a 120 day FAIR plan, then once that expires, you again have 60 days to recharge.
The newly updated bcharge app contains a disclaimer, that is displayed in English based on your system language) related to the FAIR SIM. Here is the important excerpt.
- This service uses a Private IP address. Therefore, it does not support Internet services or applications that require a Global IP address.
- The Charge Period after plan expiry is 10 days. After 10 days, it will no longer be possible to charge your SIM
