eSIM on tablet, smartwatch and laptop – what actually works
When people hear eSIM, most first think of phones, but the technology has long been available on other devices too – tablets, smartwatches, and even some laptops.
Below we explain what actually works, what to watch out for, and when it makes sense to use eSIM on a device other than your phone.
eSIM on tablets
Many tablets with mobile data capability (Wi-Fi + Cellular versions) come with a built-in eSIM chip. iPad models with the Cellular option, as well as certain Samsung Galaxy Tab devices, support eSIM similarly to phones.
The check is the same as for phones – look for the option in network settings, or check the device specs before purchase if you plan to use eSIM while travelling.
eSIM on smartwatches
Smartwatches with LTE (Cellular Apple Watch variants, certain Samsung Galaxy Watch models) can use eSIM to give you internet and calls directly from your wrist, without your phone nearby.
It's worth noting some smartwatches require the eSIM profile to be paired with a profile on a phone with the same operator, meaning not all eSIM plans are compatible with all watches – check specs before purchase.
eSIM on laptops
More and more laptops, especially business models, now come with a mobile data option and a built-in eSIM chip. This is particularly useful for business travellers who need internet without relying on a phone hotspot.
- Check the laptop has an LTE/5G module, not just Wi-Fi
- Windows laptops usually have a 'Mobile data' option in network settings
- Not all business laptops support eSIM – check the spec sheet before your trip
When eSIM on a non-phone device makes sense
If you're travelling with a laptop or tablet and don't want to drain your phone's battery as a hotspot, an additional eSIM on those devices can be a practical solution, especially for longer work sessions or video calls.
Limitations worth knowing
Not every eSIM plan you use on your phone can automatically move to another device – each device usually requires its own QR code and profile, since an eSIM profile is tied to that device's specific EID number.
Frequently asked questions
Can I use the same eSIM plan on my phone and my tablet?
No, each device with its own EID number requires a separate eSIM profile, even if the plan is bought from the same provider.
Do all smartwatches support a standalone eSIM?
No, only Cellular/LTE variants, and some require pairing with a phone on the same operator.
Do I need a separate plan for a laptop while travelling?
Yes, if the laptop has a built-in eSIM and you want to use internet directly on it, a separate profile is needed.
How do I know if my tablet or laptop has eSIM?
Check the manufacturer's device specs, or look for a 'Mobile data' / 'eSIM' option in network settings.
