Rental of 4G LTE large capacity type of global Wi-Fi "European Tour Plan".Up to 500MB a day is a guide, so I was able to use PCs with confidence.SSID and encryption keys are written on the part hidden by the sugar stick.
Vodafone Ireland prepaid SIM card is inserted on the iPhone and used for "RED roaming".During your stay in Europe, when you use it in RED roaming, which can be used without any change, switch [Data Roming] to ON in [Mobile Data Communication] on the setting screen.When you use up 200MB a day, switch this to OFF and wait for the date to change.
