Question 1

What is a pay-as-you-go eSIM?

Accepted Answer

A pay-as-you-go eSIM charges you for the data you actually use instead of selling a fixed bundle. With Roamix Omni you load a balance once, and it's deducted by the megabyte at each country's rate. Nothing is wasted when a trip ends, because the balance stays for the next one.

Question 2

What's the minimum balance I need to load?

Accepted Answer

$10. That's the only purchase you make to get connected. Once it's loaded, it works in every country Omni covers, with no separate plan to buy.

Question 3

Does my balance expire?

Accepted Answer

No. Your balance never expires, so whatever's left carries over to your next trip. There are no monthly fees and no daily charges for having Omni installed. You only pay for the megabytes you use.

Question 4

Is pay-as-you-go cheaper than a fixed eSIM data plan?

Accepted Answer

Usually, when you can't predict how much data you'll use, when your trip covers several countries, or when you travel often. You never pay for data you don't use, and in most of Europe Omni costs $1.50/GB on the preferred network. If you know you'll use a large, exact amount in one country, a fixed Roamix data plan can still be the better deal.

Question 5

What's the difference between PREF and EXT networks?

Accepted Answer

PREF stands for preferred: it's the main partner network in each country and normally the cheaper of the two, with the exact rate set per country. EXT stands for extended: extra carriers Omni can also use for wider coverage, each priced by that network, so two EXT networks in the same country can have different rates.

Question 6

Do I choose PREF or EXT myself?

Accepted Answer

You don't have to. Your eSIM tries the PREF network first and only uses an EXT network when it's the best or only option where you are. If you'd rather decide, you can pick PREF or EXT at any time in your phone's network settings. Every gigabyte is billed at the rate of the network you actually used.

Question 7

Can I use Omni in more than one country on the same trip?

Accepted Answer

Yes, that's the whole point. One eSIM, one balance, no buying a new plan or scanning a new QR code when you land somewhere new. Cross a border and Omni keeps using the same balance at that country's rate.

Question 8

What happens when my balance runs out?

Accepted Answer

Data pauses. You're never charged beyond your balance, so there are no surprise bills. Top up whenever you like, or turn on Auto Top-Up so your balance reloads before you're disconnected.

Question 9

How does Auto Top-Up work?

Accepted Answer

Choose a low-balance point and a reload amount, for example below $5, add $25. When your balance drops to that point, we charge your saved card and top you back up automatically, even mid-trip.

Question 10

Do I get 4G or 5G?

Accepted Answer

5G wherever the network supports it, and 4G LTE everywhere else. Open any country in the rates to see each network's fastest speed next to its name. Your phone also needs to support 5G for the 5G networks.

Question 11

Does Omni work on flights?

Accepted Answer

Yes, on selected flights with Aer Lingus, Asiana Airlines, Biman Bangladesh Airlines, Cathay Pacific, EgyptAir, Emirates, Etihad Airways, EVA Air, ITA Airways, Kuwait Airways, Lufthansa, Malaysia Airlines, SAS Scandinavian Airlines, Singapore Airlines, SWISS, TAP Air Portugal, Turkish Airlines, Uzbekistan Airways. Service depends on the aircraft, so it isn't on every flight. Look for one of the listed aircraft on your booking.

Question 12

Does Omni work on cruises and ferries?

Accepted Answer

Yes, on board ships from AIDA Cruises, Algerie Ferries, Ambassador Cruise Line, Anek Lines, Bluestar Ferries, Brittany Ferries, Carnival Cruise Line, Color Line, Condor Ferries, Corsica Ferries, Costa Crociere, Crystal Cruises, Cunard Line, DFDS Baltic, DFDS Seaways, Finnlines, Fjordline, Grandi Navi Veloci (GNV), Grimaldi Lines, Irish Ferries, La Meridionale, Marella Cruises (TUI UK), Mystic Cruises, P&O Cruises, Phoenix Reisen, Polferries, Smyril Line, Silversea, Stena Line, Swan Hellenic, UME Shipping, Viking Ocean Cruises.

Question 13

Which devices support Roamix Omni?

Accepted Answer

Any eSIM-compatible phone: recent iPhones, Samsung Galaxy, Google Pixel and most other modern Android phones. You scan a QR code and Omni installs next to your existing SIM, so you keep your number for calls and texts.

Question 14

Can I get a refund on my Omni balance?

Accepted Answer

Yes, within 14 days of purchase as long as the Omni eSIM hasn't been installed. Once it's installed, the balance is yours to use whenever you travel, since it never expires.
