Mobile-ID – a mobile identification document always within your reach
Mobile-ID enables you to access all the online services you’d normally access with an ID-card directly from your phone. Log in, sign documents, approve activities, order services, confirm transactions and so much more, without the need for a smart card reader or specialized software.
Replacement of Mobile-ID SIM Cards Has Begun
Estonian mobile operators are gradually replacing SIM cards that support the Mobile-ID service to ensure compliance with the new European electronic identity regulation.
To continue using the Mobile-ID, existing SIM cards that support the Mobile-ID service must be replaced before 19 May 2027. Detailed information about replacing the SIM card is available from your mobile operator.
For Mobile-ID users, the service will remain the same after the SIM card replacement, and access to e-services and digital signing will function as usual.
E-services do not need to make any changes to their systems.
NB! Without replacing the SIM card, the Mobile-ID service cannot be used for digital signing or authentication from 19 May 2027 onwards.
