Real Connectivity Costs for Remote Workers
Conclusion
For remote workers abroad, PuraSIM eSIM + a coworking space or accommodation with decent WiFi is the optimal setup: the eSIM as an always-available backup when WiFi fails (and in cafes, accommodations, and coworking spaces, it always fails at the worst time). With €35–50/month for eSIM, remote work from anywhere in the world is logistically viable.
Frequently Asked Questions
Is eSIM enough to work without WiFi for a whole day?
It depends on the work. For emails, documents, and voice calls: yes, perfectly. For 8 hours of HD video calls: you would consume 5–10 GB. Feasible with a generous plan.
Can I hotspot from eSIM to use with a laptop?
Yes. Activate personal hotspot on your mobile and connect from your laptop. Speed will depend on 4G/5G coverage in your location.
How many GB do I need for remote work for a month?
Between 30 and 80 GB/month, depending on the number of video calls. A full day with 3 one-hour video calls consumes 3–5 GB.
Does eSIM work with corporate VPN?
Yes. The eSIM provides the internet connection; the VPN works on top of it. Just make sure the VPN is configured for the destination (especially in countries with restrictions like China).
What happens if I run out of data in the middle of a meeting?
The connection drops. Solution: monitor data consumption with the provider's app and recharge before running out of data. Many plans allow instant top-ups from the app.
