Keep your BSNL number active while abroad

This card is mostly empty, and the empty cells are the honest result rather than an oversight. BSNL is a licensed operator in India, so the regulator's floor applies to its prepaid connections exactly as it applies to everyone else's. What we could not do is read BSNL's own statement of how it implements that floor.

What applies to BSNL regardless

The Telecom Consumers Protection Regulations bind every service provider, and the three clauses that decide the fate of an unused number are quoted in full on the India page. In short form: regulation 11 requires that no prepaid connection be deactivated for non-usage "for a minimum period of ninety days or such longer period as may be specified by the service provider", regulation 12 blocks deactivation while more than twenty rupees sits in the account, and regulation 14 keeps a deactivated number out of anyone else's hands for at least fifteen days.

Those are floors, and a carrier may be more generous than a floor. What a carrier may not do is fall below it.

What we could not read, and how hard we tried

On 22 September 2026 we tried to reach BSNL's own site with three different clients, because a single failure usually means the tool rather than the site:

• curl with a browser user agent: no response at all, connection did not complete.
• A server-side fetcher: the socket closed before a response arrived.
• Node's built-in fetch: a type error at the network layer, meaning no response came back.

Three clients, three different failure shapes, no page. So the cells above say unverified, and they will keep saying it until BSNL's own document is in hand.

What unverified means here is worth stating plainly, because the temptation to read it as a verdict is strong. It means we could not confirm the rule on an official page. It does not mean BSNL has no rule, does not mean BSNL is worse than the others, and does not mean the regulator floor fails to protect a BSNL number. A blank is a gap in our reading, and this page exists to say so rather than to fill it with a figure from somewhere else.

What to do while this card is thin

If you are on BSNL and about to leave the country, the safe reading is the floor: assume ninety days of silence is the limit, keep more than twenty rupees on the account, and treat the fifteen days after any deactivation as the whole of your recovery window. Those are the regulator's numbers, they bind BSNL, and they are the conservative end of any implementation a carrier might publish.

Then ask BSNL directly what it does on top of the floor, and if the answer arrives in writing, send it to us. This card is scheduled for another attempt in a month rather than the usual quarter, and a reader's copy of the terms would settle it sooner.

Where the verified cards are

Jio, Airtel and Vi all publish their implementations, and the three read differently enough to be worth comparing before you assume yours works like the others. They sit side by side on all carriers, and each has its own card from the India page.
