Austria eSIM: Stay Connected in the Alps and Vienna
Skip roaming fees and get online the moment you land. Here's how an Austria eSIM keeps you connected across Vienna, Salzburg and the Alps.
From the coffee houses of Vienna to the ski slopes of Tyrol, Austria rewards travellers who stay connected. An eSIM gets you online the second your plane touches down, no SIM swap, no airport kiosk queues.
Why use an eSIM in Austria
An eSIM is a digital SIM you install by scanning a QR code. Buy it before you fly, activate on arrival, and pay one upfront price with no surprise roaming bills.
Austria has excellent mobile infrastructure. Your eSIM connects to leading local operators:
A1 - the largest network, strong nationwide 4G and growing 5G
Magenta (T-Mobile) - fast 5G in cities and reliable rural coverage
Drei (Three) - solid 4G/5G, competitive in urban areas
Expect fast 5G in Vienna, Salzburg and Graz, with dependable 4G in valleys and along Alpine roads. Coverage in remote high-mountain areas can dip, as anywhere.
How to get connected
1. Buy your Austria eSIM online and check your phone supports eSIM
2. Install by scanning the QR code we email you
3. Activate data roaming for the eSIM on arrival and you're online

Light (maps, chat, email): 1-3 GB for a short city break

FAQ
Will my phone work with an eSIM?
Most phones from the last few years support eSIM, including recent iPhones, Samsung Galaxy, and Google Pixel. Check your settings for an "Add eSIM" option.
When should I install the eSIM?
Install before you travel while you have Wi-Fi, then switch it on when you land in Austria. Activation is quick.
Can I keep my WhatsApp number?
Yes. WhatsApp is tied to your original number, not the eSIM, so it works normally while you use Austrian data.
Yes. Austria has excellent mobile infrastructure, and a HelloSIM eSIM connects to local Austrian networks the moment you arrive, giving you data without a physical SIM or a trip to a shop.
Is my phone compatible with a HelloSIM eSIM for Austria?
Most phones from the last few years support eSIM, including iPhone XS and newer, Google Pixel 3 and newer, and recent Samsung Galaxy S, Note and Z models. Your phone must also be carrier-unlocked.
How do I check if my phone supports eSIM before travelling to Austria?
On iPhone, dial *#06# and look for an EID number, or check Settings then Cellular for an 'Add eSIM' option. On Android, look under Settings then Network and internet then SIMs for an 'Add eSIM' entry.
How do I install my HelloSIM Austria eSIM?
After purchase you receive a QR code by email. Go to your phone's eSIM settings, choose to add a cellular or mobile plan, then scan the QR code to install the profile. It takes about a minute.
How do I install the eSIM on an iPhone?
Open Settings, tap Cellular, then Add eSIM or Add Cellular Plan, and scan the HelloSIM QR code. Label the plan 'Austria' and keep your home SIM as the default voice line if you wish.
How do I install the eSIM on an Android phone?
Go to Settings, then Network and internet, then SIMs, tap Add eSIM or the plus icon, and scan the HelloSIM QR code. Steps vary slightly by brand such as Samsung, Pixel or Xiaomi.
Do I scan a QR code to set up the eSIM?
Yes, scanning the QR code is the easiest method. If you are installing on the same phone that received the email, you can also enter the activation details manually instead of scanning.
Should I install the eSIM before or after arriving in Austria?
Install the eSIM profile before you fly while you still have Wi-Fi, but wait to enable data roaming or set it as active until you land in Austria so your validity period starts when you actually need it.
When does my Austria eSIM data plan start counting down?
Most HelloSIM plans start when the eSIM connects to an Austrian network for the first time, not at the moment of purchase, so you can buy and install ahead of your trip without wasting days.
Which networks does HelloSIM use in Austria?
HelloSIM roams on Austria's major mobile operators, which are A1 Telekom Austria, Magenta Telekom and Drei (Three). The exact network is assigned automatically for the strongest available signal.
Is there 5G with a HelloSIM eSIM in Austria?
Yes, where 5G is available and your plan and device support it. Austria has broad 5G coverage in Vienna, Graz, Linz, Salzburg and other cities; elsewhere you will typically connect on fast 4G/LTE.
How good is mobile coverage in Austria?
Coverage across Austria's cities, towns and main road and rail corridors is very strong. Signal can weaken in deep alpine valleys, high mountain passes and remote hiking trails, which is normal terrain-related behaviour.
Does the eSIM cover Vienna, Salzburg, Graz and Innsbruck?
Yes. All of Austria's major cities including Vienna, Salzburg, Graz, Innsbruck, Linz and Klagenfurt have dense coverage, so you will have reliable data in urban and tourist areas.
Will the eSIM work at Vienna Airport when I land?
Yes. Vienna International Airport (VIE) has strong network coverage, so once you enable your eSIM and data roaming after landing you should connect within a minute or two, ideal for booking transport or checking maps.
Can I use my HelloSIM Austria eSIM in other EU countries?
It depends on your plan. A single-country Austria plan works only in Austria, but HelloSIM also offers regional Europe plans that cover Austria plus other EU countries such as Germany, Italy and Czechia on one eSIM.
Do I need a separate eSIM for Germany if I have an Austria plan?
A single-country Austria eSIM will not cover Germany. If your trip includes both, choose a HelloSIM Europe regional plan so one eSIM keeps you connected across the border without swapping profiles.
How much data do I need for a week in Austria?
For a week of maps, messaging, browsing and social media, most travellers are comfortable with roughly 3 to 5 GB. Add more if you stream video, make frequent video calls, or rely on the eSIM for hotspot.
How much data do I need for a two-week trip to Austria?
Two weeks of typical use often lands around 7 to 10 GB. Heavy streamers or people who tether a laptop should consider a larger bundle or plan to top up partway through.
What data plans and validity does HelloSIM offer for Austria?
HelloSIM offers a range of data bundles with validity periods commonly spanning from a few days up to about 30 days. You pick the amount of data and duration that match your trip length on the product page.
How much does an Austria eSIM cost?
Prices vary with the data amount and validity you choose, so check the live price on the Austria product page. As a guide, short low-data plans are inexpensive and cost rises with larger data and longer validity.
Is a HelloSIM eSIM cheaper than roaming in Austria?
For most travellers from outside the EU, yes. A dedicated Austria eSIM is usually far cheaper than pay-as-you-go roaming charges from a home carrier. EU residents may already have roam-like-at-home rates within the EU.
Do I need to set an APN manually in Austria?
Usually not. HelloSIM eSIMs configure automatically, but if data does not work, HelloSIM provides the correct APN in your setup details, which you can enter under your eSIM's cellular data network settings.
Do I need to turn on data roaming for the eSIM?
Yes. Because the eSIM connects to Austrian networks as a roaming partner, you must enable Data Roaming for the HelloSIM line in its cellular settings. This does not cause extra charges on the HelloSIM plan.
Can I keep my home number while using the eSIM in Austria?
Yes. With dual-SIM you keep your physical SIM or home eSIM active for calls and texts on your normal number, while the HelloSIM eSIM handles data. Just set HelloSIM as the line used for cellular data.
Will I be charged on my home SIM if I keep it active in Austria?
You will not be charged for data if you set HelloSIM as the data line and disable roaming on your home SIM. However, incoming calls or texts on your home number may still incur your carrier's roaming fees.
Can I use the eSIM for hotspot or tethering in Austria?
Yes, HelloSIM eSIMs support personal hotspot in Austria, so you can share your connection with a laptop or tablet. Tethering uses your plan's data allowance, so a hungry device will consume your bundle faster.
Can I make phone calls and send SMS with the eSIM?
HelloSIM eSIMs are data-only, so they do not include a local Austrian phone number for regular calls or SMS. You can still call and message over the internet using WhatsApp, FaceTime, Telegram or Signal.
Can I use WhatsApp and video calls on the Austria eSIM?
Yes. Data-based apps such as WhatsApp, FaceTime, Zoom, Messenger and Telegram work normally on the eSIM's data, letting you call and video chat without a local number as long as you have coverage.
What is the emergency number in Austria?
Dial 112, the Europe-wide emergency number, which works in Austria for any urgent situation. Austria also uses 133 for police, 122 for fire and 144 for ambulance. Emergency calls work even without an active data plan.
How fast are typical data speeds in Austria?
Austria's networks are among Europe's better performers. In cities on 4G you can often expect tens of megabits per second, and 5G can be considerably faster, which is plenty for streaming, calls and navigation.
Is the eSIM good for Google Maps and navigation while driving in Austria?
Yes. Coverage along Austria's motorways and main roads is reliable for live navigation. For alpine drives with occasional dead spots, downloading offline maps in advance is a smart backup.
Will the eSIM work on trains between Austrian cities?
Generally yes. The main OBB rail corridors between Vienna, Salzburg, Graz and Innsbruck have good coverage, though signal can briefly drop in tunnels and remote mountain sections, which is normal.
Can I use the eSIM in Vienna's U-Bahn metro?
Vienna's U-Bahn has mobile coverage in many stations and stretches, so you can usually stay connected underground, though brief gaps between some stations are possible.
Can I use the eSIM in the Austrian Alps and ski resorts?
Popular ski resorts and mountain towns generally have coverage in the village and lift base areas. Higher backcountry slopes, deep valleys and remote trails may have weak or no signal, so plan for offline maps.
What happens when I run out of data in Austria?
When your bundle is used up, data simply stops working until you top up or buy a new plan. You will not be billed for overage, but you should keep an eye on usage in your account to avoid interruptions.
How do I top up or add more data in Austria?
Log in to your HelloSIM account and buy a top-up or a new data bundle for Austria. The extra data is added to your existing eSIM, so you do not need to install a new QR code.
My eSIM shows no service in Austria, what should I do?
First confirm Data Roaming is on for the HelloSIM line and that it is selected for cellular data. Then toggle Airplane mode on and off, or restart the phone. If it persists, manually select a network like A1 or Magenta.
My eSIM is not registering on a network, how do I fix it?
Go to your carrier or network settings, turn off automatic network selection, and manually choose an Austrian operator such as A1, Magenta or Drei. Restarting the phone after installing the eSIM also resolves many registration issues.
Do I need a passport or ID to buy a HelloSIM eSIM for Austria?
No. Buying a HelloSIM travel eSIM online does not require ID registration, unlike some local prepaid SIMs bought in a shop. You just complete the purchase and receive your QR code by email.
How many devices can use one Austria eSIM?
An eSIM profile installs on one device at a time. To connect a second phone or tablet, buy a separate eSIM, or use your primary phone's hotspot to share data with the other device.
Does the eSIM expire if I do not use it?
The validity countdown typically begins when the eSIM first connects to an Austrian network, and the plan is valid for its stated number of days from that point. Unused data is lost once the validity window ends.
Can I get a refund if the eSIM does not work in Austria?
If you cannot connect and the eSIM has not been used, contact HelloSIM support before or during your trip; they can troubleshoot and, where a genuine technical fault is confirmed, help with a replacement or refund per the refund policy.
What should I do before flying to make sure my Austria eSIM works?
Install the eSIM profile while on Wi-Fi at home, confirm it appears in your cellular settings, keep Data Roaming off until you land, and save your QR code and HelloSIM login in case you need support on arrival.
Any traveller tips for staying connected in Austria?
Download offline Google Maps for cities and alpine areas before you go, keep your home SIM active only for essential calls to avoid roaming fees, and enable Wi-Fi calling so you can still reach your home number over data.
