Just swapped the sim cards and a quick reboot, you are ready to go. There is no way you are going to use 20gb in 14 days but good luck. Highly recommend. Total plug and play as long as your phone is unlocked.
Great product. I purchased two cards for use in multiple European countries ( Austria, Slovakia, Czech Republic, Hungary, Poland). I installed the Sim cards on our arrival and the iPhones immediately connected to the network and activated.
I had my trip to Finland. I had taken other company card with me but all of the sudden the card lost network and then my friend told be to buy e sim really easy and fast I was again connected I found it lifesaving.
