An eSIM is a SIM built into your phone that you set up digitally, with no plastic card. For remote workers it makes a handy backup: if your home broadband or the coworking Wi-Fi drops during a call, you can switch to a mobile data plan and keep working. You need an eSIM-compatible phone, an unlocked device and a plan you have set up before you need it.
What is an eSIM, and how does it differ from a regular SIM?
A physical SIM is a card you insert. An eSIM is a chip already inside the device, and your carrier's details are installed on it as a downloadable profile. The GSMA, the mobile industry body, describes eSIM as a way to change or add subscriptions without swapping a card. In practice you scan a QR code or sign in to an app, and the plan appears in your phone's settings.
Why would a coworking member or home-office worker want one?
Most people think of eSIMs as a travel tool. For a freelancer or remote employee they solve a more common problem: a connection that fails at a bad moment.
- Backup for outages: if your broadband or shared office network goes down, your phone can share its data as a hotspot.
- A second line without a second card: many phones can hold more than one eSIM, so you can keep a work or data-only plan next to your personal number.
- Quick setup on a short trip: a client visit abroad no longer needs a shop visit for a local SIM.

How do you check that your phone supports eSIM?
Look in your phone's settings for an option to add a mobile plan or eSIM, or check the manufacturer's specification page for your exact model. Support depends on the model and sometimes the region it was sold in. Your phone also has to be carrier-unlocked, which you can confirm with the carrier that sold or financed it. Company-issued phones are often locked or managed, so ask your IT team first.
How do you set up an eSIM step by step?
- Choose a plan. Pick a provider whose coverage matches where you work, and read the data limit, validity period and whether hotspot sharing is allowed.
- Buy and receive the activation details. This is usually a QR code or an in-app install button.
- Install the profile. Follow the phone's prompts to add the plan. Do this on reliable Wi-Fi, because the phone usually needs a connection to download the profile.
- Label the line so you can tell it apart from your main number, and choose which line is used for mobile data.
- Test it. Turn Wi-Fi off briefly, load a page and try the hotspot with your laptop before you rely on it.
What should you compare between eSIM providers?
| Check | Why it matters |
|---|---|
| Coverage and network partners | Plans are only as good as the local networks behind them. |
| Hotspot allowed | Some plans restrict tethering, which is the main reason a remote worker wants the plan. |
| Data amount and expiry | Video calls use far more data than email, so match the plan to how you work. |
| Voice and SMS | Many travel plans are data-only, so two-factor codes may still go to your main number. |
| Refund and top-up terms | Know what happens when the data runs out. |
Can you rely on mobile data for work calls?
For a backup, yes, with care. Keep a stable spot with good signal, close heavy background apps, and lower video quality if the call stutters. Watch your usage in the phone's data settings so a long call does not use up the plan. If you work this way often, a plan sized for it will be cheaper than repeated top-ups, so check the provider's current prices rather than assuming.
What else belongs in a flexible work kit?
An eSIM is one piece of a setup that works wherever you are. Pair it with a charger, a headset and a laptop stand; our portable home office kit covers the rest. If you also travel for work, the packing checklist helps you decide what to bring. Teams that let people work from abroad can add eSIM guidance to their policy alongside tax and meeting hours.
Set the eSIM up on a calm day, test the hotspot once, and you will not have to think about it when the Wi-Fi fails.
