Both eSIMs and physical SIMs do the same basic job: they connect your phone to a mobile network. The difference is how they do it.
A physical SIM is the little plastic card you insert into your phone.
An eSIM is a built-in digital SIM you activate by scanning a QR code or entering a code
If you travel, swap plans, or just like things simple and digital, the choice between the two matters.
One travel card, all the perks

What is a Physical SIM?
A physical SIM card is:
A small removable chip that slots into your phone
Tied to a mobile plan and phone number from your carrier
Easy to move between phones—just take the card out and insert it into another device (as long as it’s compatible and unlocked)
Pros:
Works on older and newer devices
Simple to understand: card in = service on
Easy to hand to someone else or move between phones
Cons:
You can lose or damage the card
Swapping SIMs when travelling can be fiddly
You’re limited by the number of SIM slots in your phone
What is an eSIM?
An eSIM is a software-based SIM built into your device:
No physical card required
You add a plan by scanning a QR code or entering activation details
Many phones let you store multiple eSIM profiles and switch between them in settings
Pros:
Great for travel – you can buy and activate a local plan before you land
No tiny card to lose or swap
Easy to switch providers or plans without visiting a store
Often lets you keep your main number active while using a local data eSIM
Cons:
Only works on eSIM-compatible devices
Moving an eSIM between phones can be a bit more techy than swapping a physical card
If your phone dies, you can’t just pop the SIM into a backup device unless you re-activate the eSIM
eSIM vs Physical SIM: Which One is Better?
It really depends on how you use your phone:
Choose a physical SIM if you:
Have an older or budget device that doesn’t support eSIM
Rarely travel and mostly stick with one carrier
Like the idea of a simple, removable card you can move between phones
Choose (or add) an eSIM if you:
Travel often and want cheap local data without hunting for kiosks
Want to set up plans instantly from your couch or at the airport gate
Like having multiple plans (for example, one for home, one for travel) on the same phone
Don’t want to juggle physical cards
Plenty of people use both: a physical SIM for their main Canadian plan, and an eSIM for short-term or travel data.
How to Decide What’s Right for You
Ask yourself:
Does my phone support eSIM?
Do I travel enough that local data plans would save me money?
Do I prefer set-and-forget (physical SIM) or flexible and digital (eSIM)?
