To prevent account balance deduction, BSNL Mobile customers who does not require ISD facility may deactivate the service by sending SMS - DEACT ISD to 53733Mobile customers have been receiving missed calls from unidentified / unknown International Number, especially those beginning with +263 & +960 etc. Customers should think twice before calling back to these unknown International (ISD) Numbers.

BSNL already received complaints from customers about Missed call fraud wherein people get missed calls from malicious international numbers like +263xxxx & +960xxxxx and when the user calls back they are charged a huge sum like Rs 45 to Rs 50 per minute for the call.

To eliminate 'One Ring Scam' or Wangiri Calls, the Telecom Regulatory Authority of India (TRAI) issued a directive on September 2012, to all operators to ensure that NO ISD facility is activated on prepaid SIM without the explicit consent of the consumer. As per this directive, BSNL already deactivated the ISD facility of it's Prepaid Mobile customers.

Customers who need ISD out going facility may activate the same by sending SMS ACT ISD to 53733.

  1. BSNL Kerala itself is cheating customers, They redirect you to a url which says topup after FUP, I topped up for Rs. 500. The next day I gor the same page saying FUP over, I was surprised and contacted he local exchange, They told me it is a software error and restored speed, Just one day later the same thing today, It is going on. I'am considering filing a criminal complaint against BSNL Kerala people for cheating, extortion and breach of trust, Contacted a lawyer today. Let us see what comes up

  2. This is right. I'm also getting messages from BA-BSNLDC on my mobile, as well as redirection on my browser, telling me that my FUP has been exceeded (even though I'm on an unlimited plan that does not have an FUP), directing me to go to to do a top-up. Something's fishy.
