Why buy a United States travel eSIM from Olysim
Pick the size that fits the trip
A long weekend and a month in United States need very different plans, so you choose the data and the days. Around 3GB covers a week of maps, messaging and a daily scroll; 10GB carries a fortnight with video calls home.
Set it up at home, land connected
The QR code arrives by email seconds after payment. Scan it on wi-fi before you leave, and the United States line comes alive on its own once you land and switch it on.
Someone answers, any hour
Stuck on the install, or the line will not attach after landing? Message us and a person replies, whatever the hour is where you are.
What is an eSIM and how does a travel eSIM work?
A SIM built into the phone
Phones from the iPhone XS onward, and most Android flagships since 2019, carry an eSIM slot alongside the usual tray. Adding a travel plan writes it to that slot, and your everyday SIM stays where it is.
The QR code is the plan
Scanning the code from your email writes the plan onto that handset. It installs once and stays there, so scan it on the phone you are actually travelling with.
Skip the arrivals counter
Buying a local SIM at arrivals usually means a passport, a form and a queue, in a language you may not read. An eSIM is already on the phone when the wheels touch down.

United States eSIM: frequently asked questions
Any carrier-unlocked phone with eSIM support works - iPhone XS or later, and most Android flagships from 2019 onward. Check your phone's network settings for "Add eSIM" before you buy.
Install it anytime before you fly, while you still have Wi-Fi to scan the QR code. Data only starts counting once you land and connect in United States.
Yes, and data is what runs maps, messaging, internet calls and the rest of your phone in United States. Around 3GB is a comfortable week of that.
You can top up the same eSIM from the Olysim app or website in a couple of minutes, so a slow connection in United States never means starting over with a new plan.
