Ubigi promo code EDC10 applies a 10% discount to Ubigi travel eSIM data plans, taken off the plan price at checkout. This guide explains what Ubigi actually sells, how the discount behaves across the different plan types, and the two checks worth doing before you buy anything.

Ubigi is the consumer travel eSIM brand of Transatel, a French mobile network operator that is now a subsidiary of NTT, the Japanese telecoms group. That ownership is more relevant than it first appears. A large share of the eSIM market consists of resellers who buy wholesale capacity and repackage it under their own branding. Transatel operates its own core network and holds direct agreements with carriers, which is why Ubigi tends to score well on network quality in independent testing rather than on price.

The product itself is a digital SIM profile you install on a compatible device instead of collecting a plastic card. Coverage extends across 200 or more destinations, sold as single-country plans, regional bundles covering Europe, Asia, the Americas, Africa, the Middle East, Oceania or the Caribbean, and global plans spanning a large share of the catalogue at once.

Ubigi is also a substantial business-to-business operation, supplying embedded connectivity for connected cars from manufacturers including BMW, Toyota and Jaguar Land Rover. The consumer travel plans that EDC10 applies to are sold through the Ubigi eSIM store and the Ubigi mobile app.

EDC10 is a straightforward percentage reduction entered in the promo code field at checkout. It changes the price you pay and nothing else — the data allowance, the validity window and the covered destinations are all determined by the plan you selected, not by the code.

The cheapest option and the right choice for a single-destination trip. Allowances and durations vary by country, and pricing differs substantially between destinations depending on Transatel's wholesale costs there. Japan is a particularly strong market for Ubigi because it runs over NTT Docomo, which gives coverage well beyond the major cities.

Sensible for multi-country itineraries. A single Europe or Asia bundle avoids buying and juggling several country plans, and usually works out cheaper than the sum of its parts. Check the destination list carefully — regional definitions differ between providers and the country you assumed was included may not be.

The most expensive tier, and the one where a percentage discount is worth the most in absolute terms. These suit long multi-continent trips or people who travel frequently enough that buying per-destination becomes tedious.

An eSIM only works on hardware that supports it. Recent iPhones, recent iPads, most flagship Android handsets and Windows 11 machines with cellular modems generally do. Budget Android phones and older devices frequently do not, and a handset still locked to a carrier may refuse to install a third-party profile even when the hardware is capable.

Check your device against Ubigi's compatibility list before purchasing. Buying a plan your phone cannot install is the single most common way to waste money on an eSIM, and a 10% discount does not soften that. Install the profile while you still have reliable Wi-Fi at home rather than attempting it on arrival — activation requires an internet connection, which is precisely what you do not have when you land.

Ubigi's unlimited plans are governed by a fair use policy, which in practice means speeds can be managed after a certain volume of high-speed data. The thresholds vary by plan and are not always prominently displayed, so read the plan detail page rather than assuming unlimited means unmetered at full speed indefinitely.

The plans are data-only. There is no local phone number, so you cannot receive SMS verification codes or make standard voice calls on the Ubigi line — messaging and calling apps over data work normally. This is standard across the travel eSIM sector rather than a Ubigi failing, but it catches people out when a bank sends a one-time passcode to a SIM they left at home.

Support is the weakest part of the offering. It runs through email and a help centre rather than live chat or telephone, and reviewers consistently report slower responses than the sector average. The purchase experience on the website is also dated compared with newer competitors; the mobile app is the smoother route.

If you have already settled on Ubigi, EDC10 costs nothing to apply and reduces a price you were going to pay regardless. There is no argument against using it.

The more useful question is whether Ubigi is the right provider for your trip. It is a genuinely good network with unusually solid infrastructure behind it, and for Japan, Europe and anyone who travels often enough to value the single-profile model, it earns its price. For a short city break to a mainstream destination where you will use a couple of gigabytes, cheaper providers exist and 10% will not close that gap. Pick the provider on coverage and price for your specific destination, then apply the code once the decision is made.

Promotional terms, eligibility and values are set by the provider and can change at any time. Always confirm the current terms on the official site before signing up or completing a purchase.
