Before applying a discount to a travel eSIM, most people want the same handful of details confirmed: what the code does, where it goes, and what might stop it working. The answers below stick to what is known about Ubigi's 10% code and flag the points you need to check yourself.
EDC10 takes 10% off the plan price at checkout. It is a price reduction, not a data bonus, so you get the same allowance and the same validity window for less money. The worked example commonly cited is a $17 plan showing roughly $15.30 once the code is applied. If the total on screen has not dropped by about a tenth, the code has not registered.
Ubigi sells travel and local mobile data plans delivered as eSIM profiles for phones, tablets and laptops. It is a brand of Transatel, a Paris-based connectivity company owned by the Japanese telecom group NTT, and Transatel negotiates carrier agreements directly rather than reselling through intermediaries. The same company provides in-car connectivity for BMW, Audi and Mercedes-Benz, and traffic in Asia-Pacific can route through NTT Docomo. Plans are advertised in more than 200 destinations. The service is data-only: there is no phone number for traditional calls or SMS, though messaging and calling apps work over data.
There is a dedicated coupon/promo code field on the payment or summary step. In the app it sits just above the total; on the website it is under the order summary at checkout. The timing matters — enter the code before you select a payment option, otherwise the field may be greyed out. The full sequence is:
Confirm your device supports eSIM and is carrier-unlocked.
Sign in via the Ubigi app, ubigi.com, or the web portal at ubigi.me.
Tap the Top Up symbol to see one-off and recurring plans.
Choose your destination and a one-off plan.
Enter EDC10 in the coupon field and press Apply.
Confirm the total has fallen by a tenth, then pay.
Install the eSIM profile by QR code or direct install while on Wi-Fi, then enable the line and data roaming on arrival.
The discount applies across the catalogue except monthly data plans. Choose a one-off prepaid plan rather than a monthly recurring one if you want the code to work. Plans are listed with a data allowance, a validity window in days and a price, and unlimited-style options exist alongside standard allowances.
Promo codes are single-use, so treat EDC10 as one per account. Only one promotion is allowed per order, meaning you should remove any other offer before applying this one. Each order can also include only a single eSIM data plan — adding a new plan replaces the one already in the cart, so multiple discounted plans in one transaction is not possible.
Yes. Codes work on the website and in the app, and the eSIM itself is supported on iOS, iPadOS, Android and Windows 10 and 11. The profile is reusable: install it once and top up the same eSIM on future trips.
Dial *#06# and look for an EID number. On an iPhone, go to Settings > General > About and look for the EID entry; the same screen shows Carrier Lock, which should read 'No SIM restrictions'. On Windows, open Settings > Network & Internet and see whether 'Cellular' appears. Verify compatibility on your own device rather than assuming.
Several points are not stated and should be checked at checkout: whether any minimum spend applies, billing currency details, and whether a chosen plan auto-renews — that setting lives in your account. Pricing and eligibility vary by country of residence, which is set when the account is created. Local taxes and card currency conversion sit outside the code's control. Ubigi is positioned toward the premium end of the travel eSIM market, so compare the discounted total against the plan you actually need. A confirmation screen and email are issued after payment.
