The quick answer is: Nope. It’s a myth that a physical SIM or eSIM is inherently faster. In fact, the speed of your connection actually depends on other factors like your network type (3G, 4G, 5G), carrier coverage, and device capabilities.
If you’re new to the idea of eSIMs, but familiar with SIM cards, you might be wondering if one is faster than the other.
With more and more people switching to take advantage of eSIM technology it makes sense to have questions about how they each work and which is the better (faster) option.
Here’s a breakdown of how to compare the two for more than just speed.
SIM vs. eSIM: What’s the difference?
Beyond just the basics of their speed, let’s quickly define each option:
Physical SIM card
A SIM (Subscriber Identity Module) card is a small physical chip that is inserted into your phone via a tiny drawer or slot to connect to a mobile network.
Its purpose is to store your subscriber information so that you are able to to make calls, send texts, and use data.
Pros:
- Easy to swap from device to device if both have slots for physical SIM cards
- They remain widely available from most carriers
Cons:
- They’re small and easy to lose, be damaged, or stolen
- Require a physical swap of SIM cards if changing networks
eSIM (embedded SIM)
An eSIM is a digital version of a SIM that’s built directly into your phone, eliminating the need for a tiny physical card.
While it functions like a traditional SIM card, instead of inserting a chip, eSIMs can be downloaded directly onto your device to activate a service.
Pros:
- No need to worrying about fiddling with swapping out physical SIM cards
- A traveller’s favourite, eSIMs allow for multiple network profiles
- They’re a secure option as they cannot be lost or get stolen
- eSIMS don’t take up extra space inside the phone, which is a feature manufacturers appreciate
Cons:
- It’s a process s the tech develops but not all carriers currently support eSIMS
- eSIMS require a compatible device for functionality
So, is SIM faster than eSIM?
Let’s be clear about busting the myth that a physical SIM card is in any way faster than an eSIM. The reality is that both types of SIMs, when connected to the same networks, would operate with comparable speeds. Neither is inherently faster than the other.
What actually affects your mobile speed?
- Network type, 3G, 4G, LTE, or 5G, is what plays the biggest role in usages speed. Note that 5G is fastest, no matter if you use SIM or eSIM.
- Carrier coverage is the next factor to consider. If you have weak signal strength, it doesn’t matter what type of SIM you use, your internet will be slow.
- Not all phones support both types of SIMs nor the current types of networks that might be faster than others.
Why choose eSIM over a physical SIM?
Beyond speed, there are other reasons people are leaving their SIM cards for eSIMs, including convenience and flexibility.
Travellers gravitate towards eSIMS for the ability to download local plans instantly. Anyone can switch between carriers without the need for a whole new SIM.
Plus, if you’ve got other things on your mind (who doesn’t?) there’s no more worrying about keeping track of a physical card.
