E signature verification failed solution - what decides it
This phrasing sits inside a cluster with 38 related UAE queries - the busiest measured at 1,000 searches a month. That matters: a page written for one exact wording answers faster than a generic category page.
Faults clear fastest when checks happen in order; jumping to a reset erases the evidence the technician needs. The ladder below is ordered so each step either fixes it or produces the one fact the next person asks for.
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?

eSIM on du: setup in five minutes
Steps
- Check the handset supports eSIM and is not carrier-locked.
- In the du app, choose line > switch to eSIM (or buy an eSIM plan for a visitor).
- Scan the QR in Settings > Cellular > Add eSIM; label the line (Work/Home).
- Keep the old line active for the first hour in case activation needs a retry, then delete the old profile.
- For travel, add the roaming or destination data pack before you fly, not at the gate.

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.

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
- Note the exact error text or light pattern, with the time
- One wired test over ethernet - keep the result and the figure
- Restart count and what changed after it (for the record, not for the technician)
- Account number and card status in the app, screenshot first
- Ask for the fault record number and the committed fix time
Mistakes that cost people money
- Resetting the router before documenting the fault - it erases evidence
- Describing the issue as "internet down" instead of the exact signal
- Accepting a verbal close without a reference number
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 getting connected case on this site, because the order is what changes the outcome - not the words you happen to use.

How this page was built
Plan names, prices and offer wording are read from verified resources, checked on 2026-09-12 20:27 UTC. Procedures follow the du Help Center articles named under each section. Demand figures - the search volumes in the tables - come from a licensed UAE search-demand dataset, which is where the "real searches" phrasings are taken from. Where a number depends on your address, your wall box or your contract start, the page says a quote is needed instead of estimating it. Nothing on this page is scraped from an aggregator or copied from another comparison site. Applied to E signature verification failed solution: diagnose it before.
Where to check it yourself
- The operator's own plan and support pages - the text your order form was written from
These pages belong to the operator and the regulator - open them side by side with your own bill or app before acting on anything here.
Verify this yourself in two minutes
- Prices and inclusions: the operator's own plan page for your emirate, then the same figure on the order form you signed.
- Your line state: the My du app - Account > Services shows suspension, bar, data cap and contract end.
