How can I activate International Roaming on my ViTM number?
Prepaid users can send an SMS to 144, a toll free number. This is applicable for Ori, Bhr, Kol, ROB circles. For the remaining circles IR service is pre-activated & users are charged a ₹99 monthly rental under chargeable events like calling, sending SMS or data being used. Postpaid users can either activate IR packs via the ViTM International Roaming Page, through the ViTM app or by calling customer care on 199.
