That would be nice, but I don’t see that as an option on my plan.
nm. DCtrix beat me to it.
I just got back yesterday and want to thank you all for posting. I made my bank aware that I’d be out of town and bought a short term international cell plan. Everything went off without a hitch. Gothenburg is a great city.
Having just come back from the UK. A couple of points that changed since last time I was there (3-4 years ago)…
- US credit cards have now moved to the 20th and you can use them in Europe pretty universally. One quirk of this is you now get the “do you want to convert to USD?” messages (aka “do you want to throw away some money?”) on every transaction (not just on some ATMs). Sometimes the server/shop-assistant will press it for you which is a pain, if they press wrong one.
- I used my US international plan on Verizon, rather than getting a UK sim card. It generally worked well except it meant my phone still thought it was a US phone which breaks some things. E.g. you cannot convince it to install the parking app I needed to pay for parking at the local station. This was infuriating as it was a confluence of two things that are personal bug bears of mine: Computers that you own but don’t let you choose what software you can install and important agencies deciding you must install an app to use them
I just returned from 3 weeks in Spain, France, and Italy. Same basic story.
US chip- or tap-equipped credit and debit cards and US phone-pay apps work pretty much everywhere with no worries. Most ATM & most CC payment devices offer to convert the charge into dollars at some rip-off rate. But some of them just do it in Euros with no option to be ripped off.
I had that same problem when I went to the States, using an eSIM. Apple wouldn’t let me install Ticketmaster app and I wanted to take my kids to an NBA game because my region is set to Japan.
There was a way be get around it, but it was a pain in the ass.
This is due to the country you have set for your Apple account, rather than your SIM. You can easily change it, unless you have subscriptions. If that’s the case, you need to sign out, create a new account in the correct region, install the app, sign out, sign back in to your regular account. The apps installed under the alternate account will continue to work.
Which of course no one has 
in addition there are other constraints on Android at least (e.g. you can only do it once every 12 months WTF ) that make that basically not an option even if you don’t.
So to convince the computer I own to install a piece of software (that I need to install to pay for &$#@ing parking because that’s what GWR have decided I need to do ) all I need to do is create a completely new fake online identity in foreign country with an associated email and foreign bank account, thats ok then . That seems like a totally reasonable thing to do to pay for a days parking.
It’s the fault of the developer that they don’t make it available in your country. As a frequent traveller, I’m just telling you how to make it work at least on iOS.
I have zero experience, but you may want to look into saily which is a data only eSIM
