Error result code e_invalidrag 0x80070057 - the fix ladder, in order - what decides it

This phrasing sits inside a cluster with 39 related UAE queries - the busiest measured at 1,900 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.

Porting a number to or from du (MNP)

Steps

1. Make sure the number is active, Emirates ID valid, and no outstanding dues on the current line.
2. Get a new SIM/eSIM from the operator you are joining and submit the port request there.
3. Do not cancel the old line yourself first - that kills the port.
4. Expect a short outage window during the swap; keep both phones charged and the account number to hand.
5. For fixed lines and home internet, porting is not the same process - book the new install before you disconnect.

du home internet not working - the 5-minute check

Steps

1. Check the light pattern first: power, WAN/optical, Wi-Fi. Red optical = line fault, not a settings problem.
2. Restart once - unplug the router for 30 seconds, not 5, then wait 3 minutes for the ONT to re-register.
3. Look for a known outage in your area before touching settings (du app > support, or the status thread for your building).
4. If the optical cable or the small white ONT box was knocked (cleaning, moving furniture), reseat the blue-tipped fibre connector gently - never bend it.
5. Still red after a reboot? Open the du app and raise a fault so the ticket timestamp starts now; escalate to us on WhatsApp and we will chase the job number.

This section is written to answer: outage; line down; no internet; los; ont.

Cancelling du home internet or a mobile line

Steps

1. Check the contract end date in the app - cancelling after month 24 avoids the penalty entirely.
2. Request the cancellation form (or use the app path) and get the reference number for the request.
3. Return or arrange collection of rented router/TV boxes; keep the receipt.
4. Pay the final settlement, which may include one month in advance plus device charges.
5. If you are switching to another operator for the same service, do not disconnect before the new line is live - book the port/install first.

This section is written to answer: cancel; terminate; unsubscribe; cancellation fee; close.

eSIM on du: setup in five minutes

Steps

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

This section is written to answer: esim; sim; activation; dual sim; visitor.

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

1. 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.
2. 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.
3. 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.
4. 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 support case on this site, because the order is what changes the outcome - not the words you happen to use.
