Is an eSIM more secure than public Wi-Fi?
Yes — using an Aria Mobile eSIM is materially safer than public Wi-Fi in cafes, airports, and hotels. Your data travels over the encrypted mobile network instead of an open Wi-Fi access point where attackers can run packet sniffers or evil-twin hotspots. For sensitive work like banking, email, or company VPN, default to the eSIM and treat public Wi-Fi as a backup.

Why public Wi-Fi is risky
Open or weakly-protected Wi-Fi networks let anyone on the same network observe traffic, run man-in-the-middle attacks, or stand up fake 'evil twin' hotspots that mimic the cafe's network. While HTTPS protects most modern websites and apps, leaks still happen via DNS, mis-configured apps, and certificate downgrades. Corporate IT teams routinely warn against using airport Wi-Fi for sensitive work for exactly this reason.
How mobile data is different
Mobile data — including eSIM data — runs over the carrier's encrypted radio link and core network. Other passengers on the same plane or other guests in the hotel cannot snoop on your traffic. The mobile carrier itself can see metadata but is regulated and audited. For routine browsing, banking, email, and Slack, mobile data is the secure default.
Best practice for business travellers
Use the Aria Mobile eSIM for sensitive work — banking, email, VPN, company tools. Reserve hotel Wi-Fi for heavy downloads (Netflix, OS updates, video calls if data is limited). Always run a corporate VPN if your employer mandates it. If you must use public Wi-Fi for sensitive activity, layer a reputable consumer VPN on top of it. Disable auto-connect to open networks in your phone settings.

- What is the best eSIM for remote workers?
For remote workers, Aria Mobile's 30-day plans in popular nomad destinations — Portugal, Spain, Thailand, UAE — are the sweet spot. Look for at least 20GB of data on a local carrier with full 4G/5G, and the ability to tether to your laptop.

There is no separate tethering toggle on our side — if it's in your data allowance, you can tether it.
