The digital nomad carries their work on their laptop and their office in their pocket. For this lifestyle, connectivity is not a luxury: it is literally the infrastructure of their business. The eSIM is the component that completes the cycle: reliable connection in any country, friction-free, without wasted time searching for physical SIMs.
Connectivity as a nomad's work tool
| Nomad's Need | Priority | eSIM Solution |
|---|---|---|
| Daily video calls without interruptions | Critical | Local 4G/5G via eSIM + laptop hotspot |
| Backup when coworking WiFi fails | High | eSIM always available |
| Connectivity upon arrival in a new country | High | Plan installed before landing |
| Tight connectivity budget | High | €20–50/month vs €200+ for roaming |
| Not losing Spanish number for clients | Medium | Dual SIM: number + data eSIM |
The digital nomad's connectivity setup
The standard digital nomad stack in 2026:

- Professional VPN: NordVPN or ExpressVPN — always active on public WiFi
- Laptop as primary device: connected via mobile hotspot when WiFi fails
- Backup plan: next month's eSIM already installed to avoid running out of data

Real connectivity costs for nomads
Advanced tips for digital nomads
- Install the eSIM for your next destination 48h before leaving: no stress upon landing
- Generous data plan: 20 GB minimum — laptop hotspot consumes a lot
- Monitor weekly consumption: adjust the plan if you have too much or too little
- Coworking as insurance: good coworkings have fiber — the eSIM is the backup
- eSIM with 5G in supported destinations: noticeable difference for 4K video calls
Conclusion
For the digital nomad, PuraSIM's eSIM with a 20–30 GB/month plan is the backbone of their connectivity. The annual cost is approximately €300 compared to €2,400 for standard roaming. The freedom to change destinations without buying physical SIMs and the peace of mind of always arriving with data ready make the eSIM the most cost-effective tool in the nomad's stack.
Frequently asked questions
Is an eSIM enough as the sole connection for work?
To work from a coworking space or accommodation with WiFi as the primary connection, yes — the eSIM is a reliable backup. To work 100% of the time only with your mobile as a hotspot, you'll need 20+ GB/month.
What happens if I change cities within the same country?
Nothing — the plan remains active. The eSIM uses the network of the same operator or the most available network (national roaming) within the country.
Can I deduct the eSIM as a business expense for self-employment?
Yes, if you are self-employed in Spain or have a company in Spain. It is a deductible communication expense. You will need the provider's invoice.
Does the eSIM work in all coworking spaces worldwide?
The eSIM works independently of the coworking space — it uses the local 4G/5G mobile network, not the coworking space's WiFi. It is compatible with any coworking space in the world.
How many GB per month does a remote web developer need?
Between 20 and 40 GB/month if using the mobile as a hotspot for the laptop. If working primarily with accommodation or coworking WiFi, 10–15 GB for backup is sufficient.
