On April 1, thousands of Mobile-ID certificates tied to SIM cards will expire as a more secure solution will be adopted by decision of Estonia's Police and Border Guard Board (PPA).
According to SK ID Solutions data, as of Tuesday more than 4,000 people have yet to update the certificates for their Mobile-ID.
The switch will affect those users who received their Mobile-ID SIM card from their mobile network carrier before 2015 and applied for its certificates in 2014.
According to Tele2 commercial product director Katrin Aron, owners of such outdated SIM cards will have to begin using the new and more secure SIM cards and apply for new Mobile-ID certificates if they would like to continue to be able to make convenient online payments and sign things electronically.
According to Aron, who noted that the final day to adopt the new SIM card is Friday, March 31, approximately half of Tele2's clients who use the Mobile-ID service have switched to the new SIM card.
