A Ubigi alternative, compared honestly
Short answer: Ubigi comes out of the carrier world rather than the travel-app world, and is known for eSIMs built into cars and laptops as well as phones. If you are buying for a phone trip, you are comparing an ordinary fixed-data plan — and should compare it like one.
Ubigi’s heritage is telecoms rather than travel retail: it is operated by Transatel, and its eSIM turns up pre-provisioned in connected cars and in some laptops as well as on phones. That heritage matters less than you would think for an ordinary holiday, but it does shape what the product is good at.
Carrier heritage, and what it actually buys you
A carrier-operated eSIM is not automatically faster or more reliable on your trip. Every travel eSIM, ours included, rides on local host networks in the destination country — none of us builds masts in Spain. What differs is which networks a provider has agreements with, and that varies country by country rather than provider by provider in a way you can generalise.
Where carrier heritage does show is in built-in devices: if you want data in a connected car, a laptop with an embedded eSIM, or an IoT device, that is a genuinely different market and we do not serve it. We sell travel data for phones and tablets.
For a phone trip, compare it as an ordinary plan
If the device is a phone, the carrier backstory stops mattering and the usual questions take over: how much data, for how many days, at what price, with hotspot allowed or not. We sell 6 data sizes from 1 GB to 20 GB across 202 destinations, from £1.49, with tethering enabled on every plan.
A worked example: 5 GB for Japan is £5.49 valid 30 days. Price the matching plan on Ubigi’s own page and compare the two. Match data and validity, not headline “from” prices.
Device support is worth checking first
Whoever you buy from, the eSIM only works on a device that supports eSIM and is carrier-unlocked. That is a property of your phone, not of the seller, so it is the thing to settle before comparing prices at all — a cheaper plan is no use on a device that cannot install it.
We keep a device list at eSIM device compatibility. Check yours there, or in your phone’s own settings, before you buy anything from anyone.
When Ubigi is the better choice
If you need data in a car, a laptop with an embedded eSIM, or another connected device, that is their market and not ours. The same applies if your device shipped with their profile already on it — using what is already installed is simpler than installing something new.
The checklist, side by side
| What to compare | eSIM Ventures | What to check on Ubigi |
|---|---|---|
| What you are actually buying | A stated number of gigabytes. 6 sizes, 1 GB to 20 GB. | Fixed data or unlimited-with-fair-use? If unlimited, find the throttle threshold before you compare prices. |
| When the data runs out | The plan stops. Nothing renews and no further charge is made. | Does it stop, throttle, or auto-renew into another charge? |
| Hotspot / tethering | Enabled on every plan we sell. | Allowed, restricted, or disallowed? This is the one most often quietly limited. |
| Topping up | Available in the app for eligible fixed-data eSIMs, under My eSIMs. | Can you extend an active eSIM, or must you buy a whole new one? |
| Keeping your own number | Yes — the travel eSIM carries data; your usual SIM stays in place for calls and texts. | Same on most eSIMs, but confirm if you need your number reachable. |
| Price you compare on | From £1.49, shown in GBP, with the checkout price identical to the listed price. | Is the headline price the price at checkout, or does currency conversion and tax change it? |
The right-hand column is deliberately a list of questions rather than answers. Ubigi’s terms are theirs to state and they change; ours are above and come from the live catalogue. Check both before you decide.
Compare us against the others
The same questions apply whoever you are weighing us against. These pages walk through each one:
- Holafly — the unlimited-with-fair-use model, and when it genuinely wins
- Airalo — the biggest marketplace, and how to price a route against it
- Saily — a data plan bundled with security features
- Nomad — fixed data, with validity and top-up as the deciding details
- All of them side by side — the checklist on one page
We quote no Ubigi prices here: they change, and a stale figure would be unfair to them and useless to you. Every figure on our side is pulled from our live catalogue. Check their current plan page alongside ours and decide on your own numbers. Last reviewed 4 November 2026.
