The UK has a strong international student community. Data from the House of Commons Library states that there were 685,565 overseas students in the UK in 2024/2025. This means that overseas students made up roughly 24% of the UK’s student population in the year 2024/2025.
The average international student is going to need a lot of tools to make their time in the UK a memorable one. One of them is a mobile connection.
The need for a stable mobile connection starts from the moment you, as an international student, land in the UK. From a quick call back home to inform your parents of your safe arrival to data to book a cab or connect with your university, there are a lot of instances where a mobile connection is essential.
Whenever the topic of mobile connection pops up, another question automatically follows: what type of SIM are you going to use?
This blog is here to answer this question. By the end of this blog, you’ll be equipped with all the information you need to make the right decision. Continue reading!
What are the differences between eSIMs and physical SIM cards?
The major difference between the two is that one is soldered into your device during manufacture, while you’ll have to manually insert/remove the other. You’d be well used to physical SIM cards, as they have been the norm, but this is changing. Many smartphone manufacturers are including an eSIM along with a physical SIM card slot. Some, like Apple, are ditching the SIM card slot altogether in iPhones sold in the US.
Here are the other differences between physical SIM cards and eSIMs.
| Attributes | eSIM | Physical SIM |
|---|---|---|
| Activation | Involves scanning a QR code. An internet connection is required. | Involves manually inserting the SIM card in the tray. An internet connection is not required. |
| Size | A physical chip that measures 6 mm x 5 mm approx. | Available in mini, micro, and nano sizes. |
| Durability | Safe from physical damage as the eSIM is soldered in the device. | Damage to contacts renders the SIM card useless. |
| Risk of Loss | Cannot be stolen. | Vulnerable to theft and SIM swapping. |
| Compatibility | Limited to modern smartphones. | Almost all smartphones with a physical SIM card slot. |
| Carrier Switching | Done digitally. | Have to manually swap SIM cards. |
| Eco-Friendliness | No plastic construction or paper packaging. Everything is digital. | The SIM card is made of plastic and often comes in paper packaging. Emissions due to logistics are also a concern. |
Now that you know how the two SIM card options stand against each other, let’s talk about the advantages and disadvantages of both eSIMs and physical SIM cards in detail.

Why eSIMs are Recommended for International Students
Here at Lyca Mobile, the only reason we’d ever recommend a physical SIM card to someone is if they have an incompatible device.
If this isn’t you, then you should always go with eSIMs in the UK.
eSIMs are extremely beneficial, as you can switch between multiple lines without the need to swap SIM cards. This makes it easy to have a UK number and a line from your home country active at the same time.
Activation is another added benefit. You can get a local number after landing in the UK using the airport Wi-Fi, removing the hassle involved in purchasing expensive SIM cards from airport stores.
And if you’re someone who’s conscious about the environment, then eSIMs are the way to go.
