We'll help you choose.
Use this page for plan questions, coverage checks, device compatibility, and business inquiries. The more specific your details, the faster we can point you to the right option.
WHAT TO INCLUDE
Send a complete inquiry.
HI9 reviews destination, device, and timing together. Incomplete notes usually come back as follow-up questions, so include:
- Every country on the itinerary, in order if you know it.
- Travel dates and how many days you need data.
- Device type: unlocked phone, portable hotspot model, or both.
- How many people or devices need to share the connection.
- Whether you already own hardware, or you are choosing a product first.
A monitored public email will appear here once HI9 is ready to receive mail at scale. Until that address is published, use the inquiry checklist above and the support pages to prepare your request, then return here for the live contact path.

SUPPORT
What we can help with.
Plan type (eSIM vs hotspot), destination coverage, setup order, and whether a device is likely to accept a given ecosystem. We do not provide voice numbers, and we will not promise compatibility we have not checked against your model.
For legal or refund questions, read Refund policy, Terms, and Privacy first.
