eSIM4Travel eSIM Plans for Japan

NTT docomo, au and SoftBank are the operators eSIM4Travel names for Japan, giving several listed networks to fall back on if one is thin outside cities. Its catalogue has a large range, so the sizing decision matters: the risk is buying more data than the trip needs. 5G is the fastest technology it states, not a guarantee of what a handset will receive. eSIM4Travel does not state where traffic breaks out, leaving delay to Japanese-hosted services and apparent IP location unclear. Top-up is listed, so an exhausted plan can be extended.
