What MUSTER does, line by line

Nine parts of the product, with the limits and rules that apply to each. The numbers here come from the same settings the product runs on.

Bulk generation

You press one button and every traveller on the roster gets their own eSIM. MUSTER shows the total for the whole roster first and charges nothing until you confirm that exact figure.

Charged
One eSIM at a time, as each order goes in
Duplicates
A traveller with an eSIM is skipped and not charged again
Interrupted run
Resumes from the next traveller

Roster import

You can type travellers in one by one or upload a CSV exported from any spreadsheet. The import tells you which lines it skipped and why.

Header row
name, email, group (group optional)
Separators
Comma or semicolon
Limits
500 travellers, 200 KB per file

Install page per traveller

Each traveller has a private page behind an unguessable link. It carries their QR code, the manual codes, and steps for iPhone and Android. Travellers need no account.

Shows
Trip, countries covered, data allowance, ICCID
Link
Unique per traveller, never listed anywhere public

Install board

One row per traveller, one colour per state, and a headcount strip across the top. MUSTER reads each eSIM's state from the network when you open the board.

Installed
The phone has downloaded the eSIM
Not installed
Issued, QR not scanned yet
Running low
80% of the data used
No eSIM yet
Not generated, or refused and credited back
Plan ended
Data used up or validity over

Plans and day passes

You choose one plan per trip from the network's live catalogue. A day pass renews its allowance each day, and MUSTER orders it for the length of the trip.

Day passes
Ordered for each day of the trip, up to 60 days
Price
Our price for the plan, shown before you confirm
Coverage
Single-country and regional plans

Credit back

If the network refuses an eSIM, MUSTER returns that eSIM's price to your trip budget in the same run and keeps the traveller on the list for your next run.

Returned
Exactly the refused eSIMs, nothing else
Ledger
Every charge and credit is a line with the balance after it

Connectivity coordinators

People you book by the slot from the same trip budget. They plan coverage before departure and stay on call during the trip.

Coverage plan
1 hour, before departure
On-call window
4 hours, during the trip
Booking
Fixed time slots, confirmed by the desk

Money

Your trip budget is a prepaid balance in the currency you choose, euros or US dollars. MUSTER runs no subscription and stores no card.

Payment
€1.00 to €20,000.00 per payment, bundles or any amount
Cards
Visa and Mastercard
Currency
Pay in EUR or USD, your choice
