How much does a Eastern Europe eSIM cost?
A Eastern Europe travel eSIM from roamsync.co starts at $0.89 for 502 MB valid 1 day. 32 plans are available for Eastern Europe, priced from $0.89 to $61.25, with validity from 1 day to 30 days. Data allowances run from 502 MB up to 50 GB. 3 unlimited-data options are also offered, subject to a fair-use policy. Connections run at 5G / 4G / 3G / 2G speeds on local partner networks. Every plan is data-only: it carries mobile internet but does not include a local Eastern Europe phone number, so calls and messages travel over internet apps such as WhatsApp. Activation is by QR code, delivered to your email and WhatsApp within seconds of purchase, and the profile installs in about two minutes on any eSIM-capable iPhone, Samsung or Google Pixel. Prices are listed in US dollars and converted to your local currency at checkout. Plans can be bought and installed before departure, so the eSIM is ready the moment you land.

Most eSIM-capable phones from the last few years work fine — this includes iPhone XS and later, Google Pixel 4 and later, Samsung Galaxy S20 and later (including Z Fold/Flip models), and recent OnePlus and Motorola devices. Your phone also needs to be carrier-unlocked. If you're not sure, check our device compatibility checker before you order.
While you're still on Wi-Fi (ideally before you fly), open Settings on your phone, go to Mobile/Cellular Data, choose Add eSIM or Add Data Plan, and scan the QR code from your order confirmation. Leave the new eSIM line installed but inactive until you land, then switch on Data Roaming for that line.
Yes. The eSIM runs on a separate line purely for data, so your existing SIM stays in the other slot for calls and SMS on your normal number — most travellers keep both active throughout their trip.
Yes — once the data line is active, every internet-based app works exactly as it would on a local SIM: WhatsApp, FaceTime, Google Maps, ride-hailing apps, streaming and email all run over the eSIM's data connection with no extra setup required.
You won't be cut off with unexpected charges — instead, simply come back to roamsync.co and purchase another plan or a top-up (where supported, this is shown as the plan's Top-Up Protocol in the order details). The new data is applied to the same eSIM profile, so there's no need to reinstall anything.
