Du block sim card - what decides it
This phrasing sits inside a cluster with 19 related UAE queries - the busiest measured at 30 searches a month. That matters: a page written for one exact wording answers faster than a generic category page.
The answer changed twice in the last year (tiers and the business bundles), so anything older than the checked stamp on this page is a suspect. The snapshot date at the top is part of the claim.
The recurring sections across those pages are: primary sidebar; 1. call the du helpline number to find puk code; 2. check your du welcome mail package. Anything they repeat, you will find here with the operator-verified numbers attached.
Change the du Wi-Fi password and network name
Steps
- Open the router admin page (usually 192.168.1.1 or the address on the sticker) and log in.
- WLAN/Wi-Fi settings: set SSID, then the pre-shared key - WPA2-PSK (AES) minimum, WPA3 if all devices support it.
- Change the router login password too; the printed default is public knowledge.
- Save and reboot; reconnect phones and IoT items with the new key.
- For smart-home gadgets that only speak 2.4 GHz, keep a separate 2.4 SSID so they survive future changes.

Activating a new du SIM or line
Steps
- Register with Emirates ID (residents) or passport (visitors) at a store, kiosk or through the app.
- Insert the SIM, restart the phone, wait for the network SMS - that is the activation signal.
- For a postpaid number transfer, complete the port request with the losing operator details.
- If the phone shows "no service", test the SIM in another handset to separate device from line.
- Visitors: a tourist line has a fixed life; extend or convert before it expires.

Can I activate without visiting a store?

Switching a business line from Etisalat to du with the same landline number - what 3 months free really saves
Steps
- Check the landline number and account-name match on the Etisalat bill - the port request must carry identical details.
- Tell the account manager explicitly: migration with number retention, not a new installation - a new install defaults to promo pricing and loses the waiver question entirely.
- Ask for both totals written on the proposal: discounted-12-month vs waiver-12-month, and tick the cheaper one.
- Keep the Etisalat service live until the agreed port date so the internet does not dip during cutover.
- If Etisalat is still inside its minimum term, read their cancellation terms before scheduling.
Does the landline number actually stay the same?
Can I get the discount AND 3 months free?
This section is written to answer: landline migration; number port; etisalat switch; fixed line waiver; business internet.

Checklist before you contact support
- Trade licence and establishment card copies ready (business lines)
- Owner EID or passport + visa page scanned
- The number(s) affected written exactly as they appear on the bill
- A quiet window for anything that touches the router config
- Written confirmation of completion before you close the request
Mistakes that cost people money
- Comparing headline speed without checking upload
- Ignoring relocation and exit fees in the totals
- Believing an aggregator price over the operator form
If you need to escalate
- Only then move to the formal complaint route with the whole thread attached. Regulators ask what the operator said, so the operator answer is your document.
- Take the evidence, not the adjective: one wired test at the time the fault happens, with the date and the figure, plus the indicator state. That is what changes the queue you are put in.
- Ask for a fault record and a reference number in writing, and ask what the committed resolution time is - then do not close the ticket when someone calls to say it is done.
- If the committed time passes, ask for a supervisor and for the written response, naming the missed commitment and requesting the credit schedule.
The same ladder is used for every account & security case on this site, because the order is what changes the outcome - not the words you happen to use.
