Ubigi is one of the few travel eSIM brands that does not put a discount banner on its own homepage. Search for a Ubigi promo code and you will find plenty of pages offering one anyway — which raises the obvious question of where those codes come from and whether they work.
Disclosure up front: we sell travel eSIMs too, so treat the comparison section at the end accordingly.
The short version
Ubigi runs no public, self-published coupon. What exists instead is three separate discount mechanisms, and they are not equivalent:
- Partner codes, typically around 10% off, distributed through review sites and affiliates
- A two-sided referral, worth more than any partner code
- A student discount, verified through Student Beans
If you are buying once and have no friend to refer you, a partner code is your realistic ceiling. If you have either of the other two routes available, take them instead — they are worth several times more.
Partner codes: real, but capped and restricted
Ubigi works with comparison sites and affiliates, and those partners get a code to hand out. These are genuine, but they come with limits that matter more than the headline percentage:
- One-time use per account. This is not a code you reuse on every trip.
- Monthly subscription plans are excluded. If you were planning to use Ubigi's recurring plan — which is one of its genuinely distinctive products — the code does not apply.
- Ubigi can withdraw or change them at any time. Partner codes are not contractual.
Because they are capped at roughly 10% and single-use, the sensible way to think about a Ubigi partner code is as a one-off welcome discount rather than an ongoing saving.
We are deliberately not publishing a list of specific codes here. Codes rot: a page listing five of them is wrong within months, and a dead code at checkout costs you more time than the discount was worth. If you want one, any current Ubigi partner will have theirs on their own page, and they are broadly interchangeable.
The referral is the better deal, if you can use it
Ubigi's referral programme is worth substantially more than a partner code, and it runs in both directions:
- The person being referred gets around 20% off their first data plan
- The referrer gets roughly a 50% discount on their next purchase
That 50% figure is the largest single discount in Ubigi's ecosystem, and it is not obtainable any other way. If you travel with someone who already uses Ubigi, having them refer you is straightforwardly the cheapest route in — and it pays them too.
The catch is structural: you need an existing user. There is no way to self-refer, and referral rewards land as account credit rather than cash.
Students get 20%
Ubigi offers a student discount of around 20%, verified through Student Beans. If you are eligible this beats a partner code outright and, unlike the referral, needs nobody else involved.
Worth checking before you spend time hunting codes — for a student the decision is already made.
"Coupon code", "voucher code" and "promo code" are the same thing
These are searched as though they were different products. They are not. Ubigi has one discount box at checkout, and coupon, voucher, promo, referral and discount code all describe something entered into it.
The one real distinction is the referral link, which is not a code you type — it applies the discount by carrying it through the link itself.
When the discount is not the deciding number
A 10% code is a small adjustment to a price, not a reason to choose a provider. Two things move the number far more:
Plan size. Ubigi's per-gigabyte price falls as the plan grows, and the gap between a small plan and a large one is usually wider than any code. Buying the size you actually need beats discounting the wrong size.
Plan type. Ubigi's monthly subscription is genuinely competitive for people who travel continuously — and it is the product most excluded from promo codes. If the subscription suits your travel pattern, the fact that no code applies to it is not a reason to avoid it.
The general rule across this market: work out the real cost per gigabyte for the trip in front of you, then apply whatever code you have. Doing it the other way round is how people end up with a discounted plan that was never the right plan. We wrote about this at length in how to actually find the cheapest eSIM.
How Wanderly compares
We built Wanderly around not needing a code. Rather than a list price with a discount programme layered on top, we show the plan price directly and compare providers side by side — so the number you see is the number you pay.
That is a genuine trade-off rather than a strict improvement. If you have a Ubigi referral from a friend, that 20% is real money and worth taking. Where we tend to win is on smaller, shorter plans, and on not making you hunt for a code at all.

Before you buy, whichever provider you choose
Check your phone actually supports eSIM. Most phones from the last few years do, but a surprising number of travellers discover the problem at the airport rather than at home — our device compatibility checker gives a straight yes or no.
