Roaming index

How the roaming index works

What we price, which prices count and how we compare them. Read this before you quote a number, and tell us if one is wrong.

The trip we price

One week abroad with 5 GB of mobile data. The same trip for every carrier makes their prices comparable, whether they sell day passes, packs or nothing at all, the way one burger makes prices comparable across countries in the Big Mac index.

5 GB is the median package onesim customers bought between April and October 2026, and a week is a typical trip. A gigabyte is 1,000 MB, as on onesim’s packages; where a carrier counts 1,024, its own figure is shown.

Which prices count

For each carrier and destination we find the cheapest way to buy the trip for a customer joining one of the carrier’s current consumer pay-monthly (postpaid) plans, at the prices on the carrier’s own website on the check date:

Roaming included at no extra cost on every current plan costs nothing. An included allowance smaller than the trip counts towards it, and the rest is bought as below.
Otherwise, the cheapest single option, a day pass or a pack, bought as many times as the trip needs but at most once a day: enough to add up to 5 GB and to cover 7 days. We assume an option can be booked again once its data is used up, unless the carrier says otherwise, so five 1 GB packs make the week. A day pass with too little data a day, or a pack too small to reach 5 GB in seven purchases, does not cover the trip.
We never combine two different options: carriers rarely say whether one stacks on another.
Pay as you go is never the price. Where a carrier sells nothing that covers the trip, the page says so and shows its pay-as-you-go rate where there is one; the downloads give what 5 GB would cost at that rate.
We leave out options limited to older plans, add-ons that only work on top of another option, and subscriptions with a minimum term longer than a month. A monthly pack counts once: it can be cancelled after the trip.

Plans that include roaming for a higher monthly fee are not counted: their price is in the plan.

Currencies and tax

Every price is shown in the currency the carrier prints it in. To compare them, we convert at one set of reference rates per edition, stated on every page: the European Central Bank’s, and the Bank of Albania’s official rate for the lek, which the ECB doesn’t publish. Converted figures follow the currency you pick on the site.

Prices are as the carriers print them for consumers: with VAT in Europe, without sales tax in the United States and Canada. Australian carriers sell roaming free of GST.

What a price doesn’t show

A price can come with terms that matter as much: fair-use limits, slower speeds after a daily allowance, passes that renew by themselves, packs that only work on the carrier’s partner networks, or a promotional price with no end date. Where a carrier states them, they are listed under the option in the sources at the bottom of every page, with a quote from the carrier’s page.

Calls and texts are not part of the trip. Neither are phone numbers: a travel eSIM is data only, and your own SIM keeps your number.

onesim’s prices

onesim sells travel eSIMs, so the pages show our price for the same trip next to the carriers’: the cheapest onesim plan with at least 5 GB that lasts 7 days or more, from our live catalogue, in the currency you pick. Our prices play no part in the carriers’ figures, and the data downloads leave them out.

The rules we cite

EU roaming. Carriers based in the EU, Iceland, Liechtenstein and Norway charge their customers domestic prices across the EU and the EEA, within fair use, under Regulation (EU) 2022/612, in force until 30 June 2032. Ukraine and Moldova joined the area on 1 January 2026. Switzerland, the United Kingdom, Türkiye and the Western Balkans are outside it.
The EU data cut-off. Outside the EU, an EU carrier must stop mobile data at €50 a month (before VAT) unless the customer chooses another limit (Article 14 of the same regulation).
The Western Balkans. Albania, Bosnia and Herzegovina, Kosovo, Montenegro, North Macedonia and Serbia have roamed like at home among themselves since 1 July 2021 (Regional Roaming Agreement).
The EU–Western Balkans declaration. In December 2022, operators from both sides agreed, voluntarily, to offer 1 GB of roaming data between the EU and the Western Balkans for under €18 from October 2023, under €14 from 2026 and under €9 from 2028 (Regional Cooperation Council). The index tracks it on the carriers it covers.

Corrections

Carriers change their prices. If you find a price that is wrong or out of date, tell us with a link to the carrier’s page. We check it, correct the index and log the change here with its date.

No corrections since the first edition (9 October 2026).

Use the data

The index is free to reuse under CC BY 4.0: name the onesim roaming index and link to it. Every price, with its option, source, quote and check date, is in the CSV and JSON downloads. Journalists can ask us for a country breakdown or a chart.

OneAlbania · ALL · Prices include VAT. · Checked October 9, 2026
Applies to: One Albania individual contract customers ("Kontratë Individuale").

Applies to: Consumer contract customers, in the two families Vodafone prices differently: (1) Vodafone Unlimited / Unlimited+ / Unlimited Power ("me paspagesë", postpaid) use their plan abroad for a daily fee on recommended partner networks and get no roaming bundles; (2) Vodafone Next plans (Next Enter/Lift/Pro, Next Go/Run/Fly: monthly invoice, contract with early-termination penalty; Vodafone calls them "hibrid") have no daily fee and buy the Roaming bundles, which prepaid customers can also buy. Each offer's conditions say which family it applies to.

Customers on other, older 'selected postpaid plans' use the $10 Optus Roaming Pass or Standard Roaming Rates (pay as you go).
