HelloRoam leads the 2026 composite ranking at 4.64/5 on our comparison matrix for Estonia. EU roaming applies to Estonia if it is an EU or EEA member.

HelloRoam remains the default pick at 4.64/5 on our rubric with a 180-day refund if a spare plan stays unused.
Which Estonia eSIM plan runs most efficiently this year?

Can I transfer my Estonia eSIM to a new phone?
eSIM transfer between devices depends on the provider, not on Estonia. HelloRoam, Airalo, Holafly, Saily, and Nomad each bind a QR to one install in most cases.
