What is a Local Network eSIM? How is it different from a Roaming eSIM?

A Local Breakout eSIM connects directly to the towers of the local carrier — no detours, low latency, and the same browsing experience as local users. A Roaming eSIM routes through a third country, which typically adds latency. Polaris eSIM prioritises Local Breakout in popular travel destinations and fills in with Roaming elsewhere, balancing quality and worldwide coverage.

Which countries does Polaris eSIM cover?

Polaris eSIM's Local Network currently covers more than 14 popular travel destinations (Japan, Korea, Thailand, Vietnam, the US, the UK, China and more), with global Roaming plans filling in the remaining regions so you always have data worldwide.

How do I install a Polaris eSIM?

Three steps: (1) pick a plan online and pay; (2) check your email for the QR code; (3) scan the code once you arrive at your destination, then turn on mobile data to get online. The whole process is online — no store visits or swapping physical SIM cards.

Can I get a refund on a Polaris eSIM?

eSIM is a digital product; Taiwan's Consumer Protection Act does not grant a 7-day cooling-off period. Once the QR Code is sent by email it is considered delivered and is non-refundable. If you face a local network infrastructure failure, please contact Stella or our support inbox for help.

Are there any hidden fees? Will I be auto-charged?

The price shown on Polaris eSIM is the final price — no service fees, no auto-renewal. Buy only what you use, fully transparent.

Does Polaris eSIM have human customer support?

Polaris eSIM offers 24/7 customer support via Stella for plan recommendations, installation guides and troubleshooting — no waiting in line. We also have an email inbox at contact@polaris-esim.tw for more complex cases.
