ABSTRAK
Pada tahun 2015, Indonesia berada di peringkat ketiga negara pengguna smartphone terbanyak dengan jumlah mencapai 65.2 juta pengguna (eMarketer Worldwide Mobile Users, 2015). Semua lapisan masyarakat kini memiliki akses untuk menggunakannya. Dalam membeli smartphone ada beberapa kriteria yang menjadi pertimbangan konsumen di Indonesia, yaitu fitur, harga, merek, serta tampilan smartphone tersebut. Namun di kondisi sekarang dimana biaya hidup terus meningkat, konsumen semakin sensitif dan selektif terhadap harga. Untuk mencari informasi mengenai kriteria-kriteria tadi, mayoritas konsumen di Indonesia menggunakan informasi word of mouth (Smartphone Buying Habit Survey by Jakpat, 2015). Erafone, ritel di bidang telekomunikasi terbesar di Indonesia yang fokus pada distribusi smartphone, adalah contoh ritel yang mampu melihat peluang dari fenomena diatas.
