This is a prepaid SIM card with 10GB of data that can be used for 180 days. - Brand: BWI SIM - Data Type: Prepaid - Data Capacity: 10GB - Validity Period: 180 days - SIM Size: Micro SIM/Nano SIM - Service PIN: Included Thank you for viewing. I purchased this on Rakuten last year for 2,380 yen. The activation deadline is approaching, so I am listing it. I inserted it into an iPhone once, but I haven't used it at all. I will sell it to someone who knows how to use it. Thank you!
