Airport will scam you out of an GBs They will sell you 32 GB card but when you leave later you will find it is only 16GB
Tip: Do not leave till your phone is working and you have looked at the available GBs. Do not let them say it will refresh when it is out this is a lie it should show you the amount of GB you purchased.
Had this happen paid for 32 only received 16GB….
