The Ubigi code EDC10 takes 10% off the plan price at checkout. That is a percentage, not a flat sum, so its cash value moves with the size of your order. The worked example cited by Ubigi is straightforward: a $17 plan should display at roughly $15.30 once the code is applied, a saving of about $1.70.
Scale that up and the picture is clear. On a small single-country data pack, the discount is worth loose change. On a larger, longer-validity plan for a multi-week trip, it is worth proportionally more in absolute money because the base price is higher. There is no cap mentioned in the terms, and no minimum spend is stated either — that is listed as an unknown, so check the plan page terms at checkout before assuming a cheap plan qualifies.
The discount reduces the price you pay. It does not add extra gigabytes. This distinction matters when comparing offers: a 10% price cut on a 5 GB plan still leaves you with 5 GB, valid for the same number of days shown on the plan listing. If your real constraint is data volume rather than budget, the code does not solve it.
Similarly, the plan remains data-only. Ubigi eSIMs carry no phone number for traditional calls or SMS. Messaging and calling apps work over the data connection, but voice calls to landlines do not. The 10% is a discount on a data service, not on a full mobile line.
Several restrictions limit how often and how widely the saving can be captured:
Monthly plans are excluded. The discount applies across the catalogue except monthly recurring data plans. If your instinct is to subscribe rather than buy a one-off pack, the code is worth nothing to you. Select a one-off plan instead.
Single use. Promo codes are single-use and EDC10 should be treated as one per account. That caps the lifetime value of the code at 10% of a single order, not 10% of everything you ever buy from Ubigi.
One promotion per order. You cannot stack EDC10 with another offer. Remove any other promotion before applying it.
One plan per order. Each order can include only one eSIM data plan; adding another replaces the plan already in the cart. You therefore cannot bundle three destinations into one large order to inflate the discount.
Entry timing. The code must go into the dedicated coupon field before you select a payment option, otherwise the field may be greyed out. Miss that window and the saving is lost for that transaction.
Pricing and eligibility vary by country of residence, which is fixed when the account is created, so the pre-discount price you see may differ from someone else's. Local taxes and card currency conversion charges sit outside the code's control, and billing currency details are not stated — check the plan page terms at checkout. A 10% discount can be partly eroded by a poor conversion rate on your card.
Ubigi is positioned toward the premium end of the travel eSIM market. It is a brand of Transatel, a Paris-based connectivity company owned by NTT, which negotiates carrier agreements directly rather than reselling through intermediaries; Transatel also supplies in-car connectivity for BMW, Audi and Mercedes-Benz, and Asia-Pacific traffic can route through NTT Docomo. Coverage is advertised in more than 200 destinations. Whether 10% closes the gap to cheaper providers is a judgement you make on the plan prices in front of you.
One piece of value is not monetary but practical: the eSIM profile is reusable. Install it once and you can top up the same profile later, across iOS, iPadOS, Android and Windows 10 and 11.
To capture the maximum, apply EDC10 to your largest single one-off plan rather than a small test purchase, since the code is single-use. Confirm first that your device supports eSIM — dial *#06# and look for an EID, or on iPhone check Settings > General > About — and that it is carrier-unlocked, shown on iOS as 'No SIM restrictions' under Carrier Lock. Then verify that the total has dropped by a tenth before paying, and keep the confirmation screen and email issued afterwards.
