I recently returned from a business trip to Japan. After long-term research, I found that the most cost-effective card is the CMLink Japan card. There is no network access fee for this card, and there is no penalty for contract termination. For friends who want to use it for a short period of time, it is really a huge blessing. You don’t have to carry it with you all the time like mobile wifi. I have used international roaming before, but it was too expensive. You can only check how much you spend when you return to your country. Once I went back to my country and saw that it cost several hundred yuan, which was scary. I have also used local Japanese phone cards, but the procedures are complicated, so I forgot about it. Later, a friend recommended that I know about the CMLink Japan card and I have been using it since then. It can be associated with domestic mobile numbers and receive domestic text messages, especially when I need a verification code urgently. I have to verify it when I first log in to the app in Japan. With the CMLink card, everything You don’t have to change cards like my friend did, haha~ And the data traffic is very strong. If you have any questions, you can directly call China Mobile’s Japanese customer service number. For business people like me who often travel to Japan and need to maintain close contact with the country, this card fully meets my needs haha~
