B-Mobile FAIR SIM option for 1 GB per month

JCI announced a new recharge plan for the B-Mobile FAIR SIM. Until now, the only option was to add 1 GB that was valid for 120 days at a cost of ¥8,350 for 120 days. This leaves you paying about ¥2,000/month for only 250 MB.

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.
