eSIM for remote work: staying connected across time zones

How remote workers and distributed teams use eSIM to stay reliably connected while working from different countries — without roaming bills or connectivity gaps.

The remote work connectivity problem

Working from home is simple. Working from a hotel room in Lisbon, a coffee shop in Medellín, or a co-working space in Bali introduces a new variable: connectivity.

Co-working spaces have good Wi-Fi — until they don't. Hotel ethernet is often blocked. A 4G eSIM connection solves all of this: you are always online, on your own connection, at speeds that support video calls, cloud sync, and large file transfers.

What remote workers need from an eSIM

Speed for video calls. Zoom, Google Meet, and Microsoft Teams at 1080p require 2–3 Mbps upload. Most LTE connections in major cities deliver 10–50 Mbps upload — more than enough. At 480p (still acceptable quality): 0.5–1 Mbps.

Hotspot for laptop. Your eSIM plan must support personal hotspot. LTE.app plans include hotspot. Tether your MacBook or Windows laptop to your phone's eSIM connection.

Enough data. Calculate your needs: - 1-hour Zoom call: 1–1.5 GB at 1080p - Slack, email, GitHub: ~100 MB/day - Light browsing and downloads: 200–500 MB/day - Streaming (after work): 1 GB/hour

For a full remote work day: budget 3–5 GB. A month of remote work: 60–100 GB. For that level of usage, combine co-working Wi-Fi for heavy tasks and the eSIM for mobility and backup.

Country-by-country setup

Europe (working remotely): One LTE.app Europe plan covers the whole continent. Cross borders between countries without buying new plans.

Southeast Asia (Thailand, Bali, Vietnam): Buy country-specific plans for each country. In Thailand, AIS is the fastest. In Bali (Indonesia): Telkomsel is the only reliable carrier — avoid others.

South America (Medellín, Buenos Aires, Lima): Claro and Movistar dominate. Coverage in city centres is excellent.

Backup strategy for remote workers

The most reliable setup: one eSIM plan as primary, one backup option available. Options: 1. A different country-specific plan for areas your primary plan doesn't cover 2. A local SIM from a supermarket (if you arrive for 1+ month) 3. Hotel or co-working Wi-Fi as the main connection, eSIM as mobile backup
