Which carriers matter, what buying a SIM involves, and when an eSIM is the smarter move.
Reliable mobile internet at better prices than most travel eSIMs, with polished iOS and Android apps and support for making and receiving phone calls.
One of the biggest travel eSIM brands, with a very large destination catalog.
Known for unlimited-data plans in many destinations, at a higher price per gigabyte.
Telekom Romania prepaid no longer exists: its prepaid customers were moved to Digi in early 2026, so ignore any guide still recommending a Telekom SIM. Digi is new to prepaid, so its retail footprint and tourist-facing plans are less proven than Orange's or Vodafone's. Romania is in the EU, so an EU SIM roams here at home rates, and local mobile data is among the fastest in the world.
Best overall coverage and speeds; the usual first pick.
Very solid nationwide and a safe alternative.
Only started selling prepaid in late 2025 after taking over Telekom's prepaid customers; coverage tops 98% of the population and it sells through its own Magazin stores.
Expect to show your passport or ID when buying a prepaid SIM; stores routinely ask for it, so have it with you.
Guac eSIM covers Romania with data plans starting from $1.50 per GB and instant activation, so your phone is online the moment you land. Airalo and Holafly are popular alternatives.
