You may have noticed that newer phones can be set up without ever inserting a SIM card. That is the eSIM at work. It is a small change with some genuinely useful implications for businesses managing several mobiles. Here is what you need to know.
What is an eSIM?
An eSIM ("embedded SIM") is a SIM built directly into the device, rather than a removable plastic card. Instead of swapping a card, you activate a mobile plan by scanning a QR code or downloading a profile. The connection works exactly the same way - it is just the form of the SIM that has changed.
How it differs from a physical SIM
| Physical SIM | eSIM | |
|---|---|---|
| Format | Removable card | Built into the device |
| Activation | Insert and go | Scan a code / download profile |
| Swapping networks | Change the card | Reprovision remotely |
| Multiple numbers | One per slot | Several profiles on one device |
| Lost in transit | Possible | Not applicable |
Why eSIM is handy for business
- Faster provisioning. New starter? You can activate their line remotely without posting a card and waiting. Great for distributed teams.
- Easier management. Networks and plans can be reprovisioned without physical swaps - which fits neatly with mobile device management.
- Dual profiles. Many phones support a personal and a work profile on the same device, which can be useful for BYOD arrangements.
- No more lost SIMs in the post or floating around a drawer.
Things to check first
- Device support. Most recent business handsets support eSIM, but older or budget devices may not.
- Network support. Confirm your provider offers eSIM provisioning for business plans.
- Process for leavers. Make sure you can deactivate or transfer profiles cleanly when staff move on.
eSIM and security
Because eSIMs are tied to the device and can be managed remotely, they fit well into a secure, managed mobile estate. They don't replace good security practice, though - read our mobile security best practices.
Make the switch smoothly
If you are refreshing handsets or onboarding a distributed team, eSIM can simplify your life considerably. Our Mobile Products service handles provisioning, management and security as one package. Request a callback to talk it through.
