eSIM adoption grows as Balkan nations mandate identity verification for digital SIMs

eSIM (embedded SIM) technology stores mobile network credentials directly in a device, allowing users to activate data plans digitally without a physical card. The technology speeds up activation, reduces the risk of lost or damaged cards, saves internal device space and lets a single phone host multiple lines, a feature embraced by manufacturers such as Samsung, Apple, Motorola and Huawei.

In several Balkan countries – Kosovo, Serbia, Bosnia and Herzegovina, Montenegro and Albania – telecom regulators require electronic Know‑Your‑Customer (eKYC) checks for eSIM purchases. Travelers must scan their passport or ID with a smartphone camera, after which the system verifies the document in a few minutes. The rule, aimed at preventing fraud and complying with national telecommunications laws, links each eSIM connection to a real person before the service can be activated.

The requirement adds a short verification step but still offers the convenience of instant connectivity for visitors, who can download a local data plan immediately after landing, provided they complete the eKYC process.
