Traditional SIM cards still work perfectly well. But there are a few advantages to eSIMs:
Speed: You can be up and running in minutes, without having to wait for a SIM card to arrive in the post.
Convenience: You can easily switch between networks, or have multiple plans without having to swap out SIM cards.
Flexibility: For dual SIM phones you can have two different plans on the same phone, or you can use an eSIM for a travel SIM when you're abroad
Security: eSIMs are a bit more secure than physical SIM cards, because they're built into your phone and can't be easily removed
No extra fees: At giffgaff, there are no differences in pricing between a plan on a physical SIM card and a plan on an eSIM.
