Until now, when I go abroad, I booked overseas mobile Wi - Fi router and received it at the airport and used it locally. It is cheaper than roaming a smartphone each, and it becomes a lifeline of a case where there is a problem with the hotel's net (Europe is roughly late!).
This time San Francisco. Sometimes referred to as short stay, I thought if I tried to try it for a while it was overseas data + SMS dedicated SMS. Put this in Shimfree's HUAWEI P 9, tethering. As usual, it is a terminal without a calling contract active in place of a console, but this time in addition to that it is a Wi - Fi router instead.
US onlyZIP SIM​ ​I tried it.
There is no problem at all and speed is not complaining. This can be used. 2 GB can be used and not used for 5000 yen, the use period is 30 days. There is also 1 GB for 2 weeks. This is less than 4000 yen.
You do not have to carry a router separately, you can keep taking pictures and keep traditional usage as SNS or HUAWEI P9.
From now on this.
