Japanese Docomo SIM cards

I’m posting onboard ship in the port of Otaru using a Japanese data SIM card I bought on eBay before leaving the U.S. I bought 2 of these cards which are by the Japanese company, Docomo, which my research showed to have the best coverage in Japan. The cards are for 8 days each, so we plan to use them back-to-back during our stay in Japan, using my Galaxy S7 phone as a hotspot for David’s Galaxy S7s and our laptop. Each card is described as “4G LTE, 3GB/8 days, unlimited.” The cards cannot be used with HTC, Blackberry, dual SIM phones or any smartphones made in China. read more
