1800 687 626 (also 1800687626): 12 scam reports describing NBN impersonation calls. Callers claim modem upgrades, request banking details, threaten disconnection.
NBN Impersonation Scam Reports for 1800 687 626
Eighteen contributors have reported calls from 1800 687 626 (also written as 1800687626) impersonating NBN technicians and Telstra staff. The overwhelming pattern involves callers falsely claiming the recipient needs a modem upgrade, router replacement, or fibre connection work. Thirteen separate reports mention callers impersonating legitimate technicians with fake employee names and ID numbers such as "Peter Wilson", "John Martin" (employee JM9748), "Travis Scott" (TS8017), and "Lisa Martin".
What makes 1800 687 626 particularly concerning is the range of manipulation tactics deployed across calls. Contributors report callers requesting banking details under false pretences, threatening immediate disconnection of phone and internet services, demanding credit card information, and pressuring elderly recipients. One 91-year-old contributor's mother received a call from 1800 687 626 where the caller claimed a modem upgrade was free but then requested credit card details and provided a specific date and fraudulent tech ID number to create false legitimacy.
What Callers from 1800 687 626 Claim
Contributors describing calls from 1800 687 626 report highly consistent deceptive claims. Callers state that the recipient's internet speed is slow, their modem needs replacement, or they have copper rather than fibre despite NBN promises. One contributor received a call claiming they needed a modem replaced for $5.85, with a technician scheduled at the highly suspicious time of 11:15 PM. Another reported a caller named "John Martin" claiming a technician would arrive at 10 AM Tuesday to install a modem, insisting everything was free except a $3 charge needed immediately by phone.
A country town resident reported a particularly elaborate version where the caller claimed they would install fibre a kilometre away from their property. When asked to download AnyDesk remote access software to "help", the contributor wasted 20 minutes before realising the scam. One caller from 1800 687 626 claimed to already know why the recipient's modem was slow and pressured them to connect to "their system" for diagnostics. Several reports mention callers giving specific fake employee names, job titles, and ID numbers to fabricate credibility. When confronted or asked for verification details, callers from this number either hung up or became aggressive and insulting.
Caller Behaviour and High-Risk Tactics
Beyond impersonation, contributors report alarming pressure and threat tactics from 1800 687 626. Three separate reports describe callers making explicit threats to disconnect phone and internet services within specific timeframes (e.g., "in 10 minutes"). A technician named "Peter Wilson" allegedly demanded bank details while threatening service disconnection. Callers have targeted vulnerable recipients, with one contributor noting her 71-year-old neighbour found the experience frightening enough to look up the number and report it out of concern for other elderly people.
The phishing element is also present: one contributor reported being asked to download AnyDesk, a remote access tool commonly used in tech support scams. Another report mentions a caller offering a phishing link alongside the impersonation. When contributors question callers from 1800 687 626 or refuse to comply, the responses vary from abrupt hang-ups to insults and escalated aggression. One caller became visibly upset when challenged, and another claimed to be calling from "Telstra HQ Melbourne" before switching to this number when asked for a callback contact.
What to Do If You Receive a Call from 1800 687 626
If 1800 687 626 calls you claiming to be an NBN or Telstra technician:
- Do not: Download remote access software like AnyDesk or TeamViewer, provide banking or credit card details, give your mobile number or personal information, or agree to immediate payment for services
- Do: Hang up immediately, block the number, and verify any legitimate service issue by calling NBN (nbnco.com.au) or your actual internet provider directly using the official number on your bill
- Note: Legitimate NBN technicians will never ask for banking details, credit card information, or remote access over an unsolicited call. Real appointments are scheduled through official channels with advance notice during normal business hours
- If pressured: Remain calm, do not engage with threats, and remember that NBN and Telstra cannot disconnect services based on an unsolicited phone conversation
Report Patterns and Timing
Community reports about 1800 687 626 span from late 2023 through March 2026, indicating this number has been used for scams over an extended period. All but one report was from calls the contributor answered or attempted to answer, suggesting active calling campaigns. The tactics intensified over time, with earlier reports (2023-2024) focused on simple impersonation and modem replacement claims, while later reports (2025-2026) increasingly involve threats, personal information requests, and urgency tactics.
One contributor received a call on 1 September 2025 from a caller named "Mary" with an Asian accent claiming a software upgrade was needed. Another experienced a call with no caller ID displayed, where the woman initially seemed unaware of the difference between ADSL and fibre technology, then transferred the call to an upset male when questioned. The variety of caller names, accents, and transfer tactics suggests multiple people or an organised call centre operation using this number.

WRITE A REVIEWFrequently Asked Questions
Is 1800 687 626 a real NBN or Telstra number?
No. 1800 687 626 is not an official NBN or Telstra contact number. Eighteen contributors have reported this as a scam number impersonating NBN technicians and Telstra staff. If you need to contact NBN or Telstra, always look up the official number on your bill or their official website rather than calling back a number from an unsolicited call.
What should I do if someone from 1800 687 626 asks for my banking details?
Hang up immediately and do not provide any banking or credit card information. Multiple reports indicate callers from 1800 687 626 have specifically requested banking and credit card details while claiming to be technicians. Legitimate NBN and Telstra staff never request banking details during unsolicited service calls. Block the number and report it to Scamwatch (scamwatch.gov.au).
Why did the caller from 1800 687 626 ask me to download AnyDesk?
This is a classic phishing and remote access scam tactic. One contributor reported being asked to download AnyDesk by someone from 1800 687 626 claiming to be an NBN technician. Remote access software allows scammers to see your screen, access files, or steal information. Never download any software during an unsolicited tech support call, regardless of what 1800 687 626 or any other caller claims.
What does it mean when a caller from 1800 687 626 threatens to disconnect my internet?
It's a pressure tactic. Three separate reports describe callers from 1800 687 626 threatening to disconnect phone or internet services within specific timeframes (e.g., "in 10 minutes") unless the recipient complied with payment or personal information requests. NBN and Telstra cannot and will not disconnect services based on an unsolicited phone call. These threats are designed to panic you into compliance.
I received a call from 1800 687 626 offering a free modem upgrade. Is it legitimate?
No. Twelve scam reports about 1800 687 626 involve callers offering free or low-cost modem upgrades. Legitimate NBN upgrades are managed through your account with official NBN channels. If you receive an unsolicited call from 1800 687 626 about a modem upgrade, hang up and verify directly with NBN using the official number on your bill or at nbnco.com.au. Do not provide payment details or schedule technician visits based on these calls.
How do I block 1800 687 626 permanently?
Contact your phone or internet provider and ask them to block calls from 1800 687 626. Most Australian telcos offer call filtering and blacklist services. You can also block the number directly on your phone device, though this only blocks future calls to your device. Reporting to Scamwatch (scamwatch.gov.au) and ACMA (acma.gov.au) helps authorities track and investigate the scam operation using this number.
