It was an ordinary day in Noida when Jyotsana received a WhatsApp call from an unknown number. The caller claimed to be a customer care executive from her mobile network provider. With a professional and reassuring tone, he introduced her to a new feature—an embedded SIM (eSIM), which he said would keep her number secure in case she lost her phone. Intrigued, Jyotsana listened.
The process seemed simple: share a code via SMS, and her eSIM would be activated. The caller also assured her that a physical SIM would arrive in two-three days. Trusting the faceless voice, Jyotsana followed the instructions.
