Bosnia and Herzegovina eSIMHow much eSIM data for 30 days in Bosnia and Herzegovina?
✓ Prices checked 22 Oct 2026For 30 days in Bosnia and Herzegovina with normal daily use, TripUtils estimates 12–18 GB. A 20 GB plan is the usual buffer. Not a live price. Sarajevo, Mostar and mountain roads are normal use for maps and messaging. Saily’s own Bosnia and Herzegovina plans stop at 5 GB, so longer trips usually need the Balkans regional plan or a top-up.

Saily plans for Bosnia and Herzegovina — snapshot
As listed on saily.com on 22 Oct 2026, in US dollars. Prices change; the live price is on Saily.
| Data | Valid | Price (as listed) |
|---|---|---|
| 1 GB | 7 days | US$4.99 |
| 3 GB | 30 days | US$9.99 |
| 5 GB | 30 days | US$13.99 |
No single Bosnia and Herzegovina plan reaches 20 GB. Saily’s Balkans plan (9 countries) lists 20 GB for 30 days at US$48.99 — or top up a smaller Bosnia and Herzegovina plan in the app.
For comparison: at the 2026 cap of €14 per GB, 20 GB on a participating home network could cost up to €280.
Roaming in Bosnia and Herzegovina on an Austrian plan: what A1 and Drei charge
Bosnia and Herzegovina is outside EU roam-like-at-home, so the EU data in an Austrian plan does not apply there. Published prices, checked on 22 Oct 2026 (euros incl. VAT):
| Network | Option | Data | Price |
|---|---|---|---|
| A1 | Roaming Pass (Zone 1) | per started GB | €4.90 |
| A1 | A1 Roaming Datenwoche | 2 GB, 7 days | €4.90 |
| Drei | Roaming-Paket Go | 1 GB, 15 days | €5.00 |
For the 20 GB planning size (30 days), A1’s Roaming Pass would bill 20 × €4.90 = €98.00, the A1 Roaming Datenwoche 10 × 2 GB = €49.00 (packages run 7 calendar days, Austrian time, and can be stacked). A1 says the Roaming Pass is switched on automatically for every tariff signed since 24 June 2026, and it blocks roaming data at a default limit of €60, which you can raise yourself. Drei packages last 15 days, so a longer trip needs packages for each period.
Magenta prices depend on the tariff — look them up in Magenta’s roaming finder. Older tariffs without these options can cost more. Sources: A1, Drei, Magenta.

Common questions
Is 20 GB enough for 30 days in Bosnia and Herzegovina?
Sarajevo, Mostar and mountain roads are normal use for maps and messaging. Saily’s own Bosnia and Herzegovina plans stop at 5 GB, so longer trips usually need the Balkans regional plan or a top-up. The 12–18 GB estimate plus buffer lands on 20 GB. Hotel Wi‑Fi is not counted. Streaming video on mobile is the usual reason to go larger.
Should I roam in Bosnia and Herzegovina instead?
Bosnia and Herzegovina is outside EU roaming. As of 22 Oct 2026, A1’s Roaming Pass bills €4.90 per started GB there (zone 1), the A1 Datenwoche gives 2 GB for 7 days for €4.90, and Drei sells 1 GB for €5 (valid 15 days). Compare that with an eSIM quote for the same GB.
Do you show live Saily prices?
