eSIM or roaming in the Balkans? Serbia, Montenegro, Albania & co. on an Austrian plan

In short

• A1 customers: the A1 Datenwoche (2 GB/7 days for €4.90) covers all six countries and costs less per GB than the Roaming Pass (€4.90 per GB, €5.90 in Kosovo).
• Drei customers: Serbia has Go (1 GB) and Go Select (5 GB); the other countries only a 1 GB package (Kosovo: Travel for €10.00). More than a few GB gets expensive.
• Magenta without a travel package: €15.36 per MB (data zones 3–5), cut-off at €60 – don’t use data there without a package or an eSIM.
• Saily (as of 22 Oct 2026, US dollars): from US$3.99 for 1 GB/7 days; fixed plans up to 30 days, unlimited for Serbia, Montenegro and Albania. For several countries: Saily Balkans.

What Austrian networks charge in the Balkans

Published prices, checked on 22 Oct 2026, euros incl. VAT.

• A1: the Roaming Pass bills per started 1 GB block; A1 says it is switched on automatically for every tariff signed since 24 June 2026, with a default data limit of €60 (you can raise it). The Datenwoche ends after 7 calendar days at midnight (Austrian time), has no commitment and can be booked several times at once.
• Drei: packages last 15 calendar days, up to 5 packages within 15 days.
• Magenta: data roaming stops at €60 without a package. Travel packages depend on your tariff – check the roaming finder.

The EU rule behind this: according to the European Commission (Your Europe), “roam like at home” applies in the EU, in the EEA countries Iceland, Liechtenstein and Norway, and in Moldova and Ukraine. Other countries are not covered – operators may extend their offers voluntarily, and roaming outside the EU/EEA can be expensive. None of the six countries is on that list.

Saily eSIM in the Balkans — snapshot from 22 Oct 2026

As listed on saily.com, in US dollars, not converted. Saily sometimes also offers shorter durations per GB size at slightly lower prices; we list the longest duration shown.

Unlimited (Serbia, Montenegro and Albania): according to Saily 3 GB per day at full speed, then unlimited at up to 1 Mbps.

7, 14 or 30 days: costs compared

Data need at normal use (0.50 GB per day plus buffer, as in the eSIM calculator). Saily in US dollars, A1/Drei in euros – we do not convert. A1 Datenwoche: enough packages for each started week to cover its share. Drei: at most 5 packages per 15 days; “–” means that is not enough.

A1 blocks at €60 by default – higher A1 totals only if you raise the limit. Magenta without a package is not listed: at €15.36 per MB, about 4 MB already pass €60.

What this means

• A1 customers: for a week with little data, the Datenwoche is the simplest option without a new eSIM. For several GB or longer trips a Saily country plan is usually cheaper – compare with your card’s exchange rate.
• Drei customers: outside Serbia there are only 1 GB packages; for normal use over a week that is rarely enough.
• Magenta customers: don’t use data without a suitable travel package – check the roaming finder or use an eSIM.
• Road trip across several countries (e.g. Croatia – Montenegro – Albania): Saily Balkans covers all 9 countries on one eSIM.
