## Frequently asked questions

**How much data do I need for the Karakoram Highway?**

Karakoram Highway (KKH / China–Pakistan Friendship Highway) typically takes about 7 days — around 4 GB at 500 MB a day, and the featured plan is picked on exactly that arithmetic. Worldwide, everyday smartphone use averages about 22 GB a month — roughly 730 MB a day — most of it video streaming (Ericsson Mobility Report, Nov 2025). On the trail the picture is lighter: with maps downloaded and video saved for wifi, messaging, photos, weather and bookings run 200–400 MB a day, so we size every recommendation at 500 MB a day for comfortable headroom. Size up if you stream, video-call or share your connection. If you would rather pay only for the days you are out, TrailSim's pay-by-the-day plans for the Karakoram Highway give a full-speed daily allowance that slows down instead of cutting off, with the number of days set on the payment page.

**What is a pay-by-the-day eSIM plan?**

A daily allowance of 300 MB to 1.5 GB at full speed, then slower for the rest of that day — never cut off. It is priced per day: you set the number of days (1 to 90) on the payment page, pre-filled with the typical Karakoram Highway trip length, and the days start on first use. It suits short trips and people who would rather never run out than carry a large fixed plan; the fixed plans on the same page are cheaper per gigabyte for a long trip.

**When do the plan days start counting?**

On first use — installing the TrailSim eSIM and connecting starts the clock, not the purchase date. You can safely buy weeks before your trip.

**Does my phone support eSIM?**

Most phones released since 2019 support eSIM, including iPhone XS and later, Google Pixel 3 and later, and most recent Samsung Galaxy models. Your phone must also be carrier-unlocked.

**What if I change my mind after buying?**

Uninstalled eSIMs qualify for a full self-service refund within 14 days of purchase — no questions asked. Once the eSIM is installed on a device it can no longer be returned.
