How to cancel the service or stop a charge for BSNL 4G SIM (Step by Step)

  1. Step 1. Call BSNL customer care at 1503. Press Mobile → Agent for the cancellation desk and state clearly: "I want to cancel 4G SIM effective today".
  2. Step 2. Note the cancellation reference number. Ask the agent to send written confirmation by SMS or email within 24 hours.
  3. Step 3. If there's an auto-debit mandate (UPI / card / NACH), ask the agent to also cancel the standing mandate. The mandate cancellation is separate from the service cancellation.
  4. Step 4. Check your bank / app within 7 days. If a charge still appears, raise a dispute with your bank quoting both the cancellation reference and the date of cancellation.
  5. Step 5. For SaaS / OTT subscriptions, additionally cancel the subscription inside the app to stop auto-renewal on the next billing cycle.

Escalation Matrix for Cancel Issues

If the first-level customer-care call doesn't resolve your cancel the service or stop a charge, India's standard escalation path is: grievance officer → nodal officer → TRAI → consumer court. Most regulators require 4 weeks of brand non-response before they accept a case, so keep every reference number and timestamp.

Frequently Asked Questions about BSNL 4G SIM Cancel

How do I stop BSNL 4G SIM auto-debit?

Calling to cancel the service is step one. Step two — and easy to miss — is asking the agent to cancel the standing mandate (UPI AutoPay / card-on-file / NACH). Without that, the system can keep retrying the charge.

Will I get a refund if I cancel BSNL 4G SIM mid-billing-cycle?

Depends on the brand's terms. Telecom & utility services usually pro-rate to the cancellation date. SaaS & OTT subscriptions typically don't refund the current cycle. Always ask the agent to quote the refund policy in writing.

What's the proof that my BSNL 4G SIM cancellation went through?

Two things: the cancellation reference number (verbal at the call), and the written confirmation (SMS / email) within 24 hours. If you don't receive written confirmation, call back the same day and re-confirm.
