A small technical upgrade can sometimes say a lot about where a market is going. Nar subscribers in Azerbaijan can now use Asan Imza, the country’s Mobile ID digital signature service, through eSIM technology. For users, the immediate benefit is straightforward: they can move from a physical SIM card to eSIM while keeping access to mobile authentication and digital signing.

The wider signal is more interesting. eSIM is usually discussed as a travel or convenience feature. No plastic card, easier device setup, multiple numbers on one phone. But when eSIM also supports a digital signature service, it becomes part of the trust layer, not just the connectivity layer.

Why this matters

Asan Imza is used for identity confirmation and electronic signing across Azerbaijan’s public and private digital services. Nar says its eSIM-based Asan Imza service gives subscribers access to more than 2,500 electronic services. That is the point where mobile identity stops being a niche tool and starts becoming everyday infrastructure.

For citizens, it can mean logging into government platforms, approving applications or signing documents without a desktop certificate setup. For businesses, it can reduce the frictions that still slow down digital administration: printing, scanning, card readers, branch visits and document chasing. None of this sounds glamorous. That is exactly why it matters.

The eSIM format also removes one weak point from the old model. A physical SIM can be lost, stolen, damaged or swapped between devices with very little ceremony. eSIM reduces the dependency on a removable card and gives users a more modern way to manage mobile identity on compatible phones. It also quietly reduces plastic SIM usage.

How it works

The service is available to both individuals and legal entities for three years. Activation is carried out at Nar Customer Service Centers, so this is not yet a completely remote onboarding flow. That may feel old-fashioned to some users, but for a digital signature product, in-person activation can still make sense when identity assurance is part of the process.

Nar’s setup also avoids pre-issued PIN codes. Subscribers set their PIN codes online during their first authentication or signing session. If PIN1 or PIN2 becomes blocked, unblocking can be handled remotely through the Asan Imza Call Center at 1847.

There is one area to watch. If Azerbaijan wants eSIM-based identity to feel truly native to digital life, activation will need to become easier over time. People accept friction for security, but they notice when other services move toward app-based onboarding.

Not only Nar

Nar is not alone in this market. Azercell also supports Asan Imza on physical SIM and eSIM, and its eSIM Asan Imza materials describe online options and transfer from a physical Asan Imza number to eSIM. Bakcell also states that subscribers can use Asan Imza through both physical SIM and eSIM.

That matters because Nar’s announcement is not just a product update. It shows that operator-supported mobile identity is becoming a baseline expectation in Azerbaijan. Once major operators support eSIM-based Asan Imza, the question becomes less “who has it?” and more “who makes it easiest, safest and most understandable?”

The strongest alternative inside Azerbaijan is SİMA. Unlike SIM-based Asan Imza, SİMA is a cloud and app-based digital signature using public key and face recognition technologies. For users who do not want their digital signature tied to a specific operator or SIM profile, that model may feel lighter. For users already comfortable with Mobile ID and operator-supported trust, Asan Imza on eSIM remains practical.

The European comparison

Europe has been moving in the same direction, although with different models. In Estonia, Lithuania and Latvia, Mobile-ID and Smart-ID have made mobile authentication and document signing part of normal digital life. Smart-ID is relevant because it shows how app-based identity can scale beyond the SIM card while still supporting strong authentication and electronic signing.

Sweden’s BankID is another useful comparison. It is bank-issued rather than operator-led, but the behavioral lesson is similar: once a trusted digital identity becomes widely accepted, people stop thinking of it as a “signature product” and start treating it as the normal way to access services.

At EU level, the European Digital Identity Wallet will push this further. The European Commission says Member States must offer at least one wallet by the end of 2026, with the framework designed for digital identity, credentials and electronic signatures across borders.

Final thoughts about Asan Imza eSIM

Nar’s eSIM-based Asan Imza service is not flashy, and that is probably its strength. It solves a practical problem for users who already depend on mobile digital identity, while aligning Nar with a broader shift in telecom: the SIM is becoming less visible, but more strategically important.

This will not be the perfect solution for everyone. Occasional users may prefer app-based identity. Cross-border European users may need eIDAS-compatible options. Some business users will want more remote activation and cleaner admin flows.

But for Azerbaijan, the direction is clear. Connectivity is no longer only about getting online. It is becoming part of how people prove who they are, sign what matters and move through digital services with less paper in the way. Operators that understand this will not just sell access. They will help define trust.
