Mobile devices can support two active SIMs at one time, so you can use a Slice eSIM alongside your current SIM. We will also provide you with a new phone number for the Free Trial. Your device will have two live phone numbers.
When you download a Slice eSIM via our app, we provide all of the details required to enjoy a successful Free Trial with us, but here are some of the options that make it easy to undertake a Free Trial without impacting your current service.
Primary vs Secondary data: You can select your Slice eSIM to be your primary SIM for data, meaning your Slice eSIM will be used for data usage.
Data switching: You can turn data switching on in your settings, this means your phone will use data from whichever SIM has the best coverage at any given point.
Primary vs Secondary calls & SMS: You can select your existing SIM to be your primary SIM for calls and texts, meaning your existing SIM will be used for outbound calls and texts. This means you won't be calling your mates off a random number.
