Lol! I do love my app….. 🤣 I also love my esims. And I woke up a long time ago.
Dick, for the BudapestGo app, you download it and set up an account ahead of time. I cannot find this anywhere on my account, but I feel like I used my passport (I understand you can use your DL but personally not sure). It never shows up again. I also entered all my payment info (your question just reminded me to update my new cc info). I am still a relative newbie, but have spent over 4 weeks in 3 trips in the last 17 months and never been asked for documentation. Doesn’t mean it can’t happen. It’s just my one person data point.
Once you have the app set up, you can buy your card or pass (or the 100E bus from the airport) as early as 30 days ahead - and tell the app the day you want it to start. You can buy single tickets as well, but can’t see the point of that.
Using the app requires you have data available.
For the metro, there are 2 ways to use it:
1. At the entrance to each station, there are small machines with a QR code. You open the app, choose Scan, and scan the QR code. This gives you a funny little dancing figure on your screen. This is what you would show an inspector. It stays there even if you close the app and reopen it when you leave your destination station.
2. There’s a feature that uses your location to find the closest metro stations, gives them to you, and before you board you choose which one you are taking. If you do this, you don’t have to scan. But you still get the little dancing picture.
For trams, no need to scan.
For most busses, no need to scan. There ARE some busses where everyone enters through the front door and exits through the back door. Apparently these are the ones you need to scan. I have only found one of these (on Margrit Island), but I am sure there are others.
Ok, and since you asked…. 🤣 Third way: My last weeklong trip in October, my app would not scan the QR code. It told me I didn’t have data, which I did. I even went to an office to ask and the guy told me I was on 3G and the app only works on 5G. (My data did everything else except the app so I am reluctant to believe this was the problem.) However. I wish I could remember where, but in the app there was a place to touch that brought up a QR code (no scanning involved), but no dancing figure, and this worked just fine. Numerous inspectors saw it and shooed me on through and I saw quite a few other people doing the same thing (young and old alike). This workaround isn’t mentioned anywhere and hopefully this is a temporary bug of some kind. But it seemed to be recognized. I was nervous at first, but I suspect it told them I had a valid pass, even if not info for a particular station.
But to Mr. É’s point about waiting. You have to walk into a metro station prepared. You can’t get to the escalator or little machine and THEN pull out your phone to start. Then there’s a line of impatient people behind you.
Another aside. The app will journey plan for you. Google Maps also does a good job. However one fluke for me is that Google Maps never includes the M1 Opera to Deak Ferenc. And I tend to use the M1 quite a bit but I guess it thinks I should walk…..
I like having my app set up and ready when I arrive. I know logically stopping for a paper pass doesn’t really take a lot of time but I like being ready to go. I also don’t like little pieces of paper. I worry about losing them. That’s also why I love esims instead of a physical sim.
I also travel with my phone handy, not hidden away in an inner pocket or purse. I also do not consider pickpockets in Budapest. I pay attention, and if I left my phone somewhere it might disappear, but pickpocketing not a thing there like some cities. And this makes using my phone for apps easier as well.
