SIM PIN, PUK and the blocked-card count: what each lock is for and how it is released

What to answer first, ranked from the data

Score is sqrt(volume) x a difficulty allowance x an intent weight for pricing and outage wording. It is a ranking rule, not a promise - but it is why this page leads with what it leads with.

What people actually search here

This topic is 12 real phrasings carrying 160 tracked searches a month. The three that open it: du sim card blocked / du puk code unlock / du puk code. They are grouped here instead of listed twice - the individual rows are in the coverage map below.

The searched questions, answered

Plans and what they cost over the term

Ordered by how well each tier answers the wording here - "du sim card blocked" first among 15 published tiers. A tier that cannot be delivered to your unit is not cheaper for being a lower number. The rotation is deliberate: the tier that matches the phrasing you searched is the one worth quoting, so the table is sorted by that fit and then by price rather than by catalogue order.

Reading the phrasings themselves

For “du sim card blocked” (30 searches a month): it is a specific enough phrase that a generic paragraph is the wrong answer; the useful reply names what depends on the account and what does not.

For “du puk code unlock” (30 searches a month): it asks for a shortcode, and codes change per service; the code is worth less than the account state it reads, so confirm both.

For “how to get puk code for du sim” (20 searches a month): it asks for a shortcode, and codes change per service; the code is worth less than the account state it reads, so confirm both; it is a procedure question, so the value is in the order of the steps rather than their existence - doing the right one first is what saves the callback.

For “puk code du” (20 searches a month): it asks for a shortcode, and codes change per service; the code is worth less than the account state it reads, so confirm both.

What the wording of these searches tells you

• Activation problems are usually the profile or the identity check rather than the network, so confirm the handset is unlocked and the registration step is complete before re-scanning anything.

Coverage map: every phrasing this page answers

Every row is a real query inside SIM PIN, PUK and the blocked-card count: what each lock is with its measured volume and difficulty. A guide that cannot answer all of them is not a guide for the topic, which is why the list is printed.

Checklist before you act

• Never share a one-time code to "confirm" anything
• Ask what protection exists on number ports
• Change router admin credentials on install day
• Review connected devices monthly
• Treat any inbound contact about your account as unverified until checked in the app
• Name the exact phrase you searched - "du sim card blocked" - in your first message, because it selects the queue your case belongs to.

Mistakes that cost people money

• Describing the symptom without the time it happens
• Accepting a verbal closure with no reference number
• Changing two variables at once, so neither result means anything
• Deciding from one data point instead of a pattern
• And the structural one for du sim card blocked: writing advice for 12 phrasings under a account & security heading and leaving the account-specific number unverified.

How to read the numbers on this page

12 phrasings and 160 searches a month is not one question but a family of them, opening on du, how, puk. That mix is why a price table alone fails here: each phrasing asks about a different stage of the same decision.

Average difficulty across the tracked phrasings is 0. Low difficulty at this volume usually means the ranking pages are thin listings, so a page that walks through the check order competes on usefulness rather than on tricks.

Read the cost table as arithmetic, not as an offer: it multiplies the published tier price by the contract length and shows what a VAT-inclusive quote would add. Installation, device instalments and account credits are not in it, because only your address and account can settle those.
