I want to upgrade my EE SIM to the 25gb SIM but at the checkout it's say's EE multi SIM so I was a bit reluctant to go ahead just incase I get charged for 2 SIMs.
Multi Sim is just the Name of a 3 in One Sim Type, ie, its a Single Sim that you just push out the correct Size to fit your device (most are the smallest Nano type now)
