Telecom: Technical Support for Broadband and Mobile with RAG
How telecom operators use RAG to automate technical support and reduce call center volume.
Telecom: Technical Support for Broadband and Mobile with RAG
Telecom operators manage millions of subscribers whose equipment constantly evolves: routers, TV boxes, smartphones, mobile plans. Each new technology (fiber, 5G, WiFi 6) generates its own set of technical questions. RAG (Retrieval-Augmented Generation) transforms an expensive and overwhelmed support system into intelligent assistance available 24/7.
The Technical Support Challenge in Telecom
An Industry Under Pressure
A mid-sized telecom operator faces:
- 3 to 10 million active subscribers
- 200,000 to 500,000 calls per month to support
- 65% of calls concern simple technical issues
- Average wait time: 12 to 25 minutes
- Cost per call: $10 to $18
The vast majority of subscribers contact their operator at least once a year, most often for a technical issue.
Equipment Diversity
Technical support must master:
- Routers: 5 to 10 different models in circulation
- TV boxes: varying interfaces and features
- Smartphones: hundreds of models, iOS and Android
- Connected devices: WiFi extenders, cameras, smart home
- Services: TV, VOD, cloud, security
Each device has its own troubleshooting procedures.
Customer Expectations
Subscribers want:
- Immediate resolution: no phone queue
- Step-by-step guidance: clear, visual instructions
- Accurate diagnosis: understanding the root cause
- Autonomy: self-solve when possible
A growing share of customers prefer self-service to resolve simple technical problems themselves.
Current Support Limitations
Existing tools struggle to deliver:
- Static FAQs: too generic, not model-specific
- Scripted chatbots: "Let me transfer you to an agent"
- Community forums: contradictory, unofficial answers
- Call centers: overwhelmed, high turnover, expensive training

Concrete Use Cases
1. WiFi Connection Problem
The problem: "My WiFi stopped working this morning"
The RAG solution:
Customer: "I have no WiFi since this morning, it was working last night"
Assistant: "I understand, that's frustrating. Let me check your situation:
Your equipment: Fiber Router Model 6 (installed 03/15/2025)
Network check: No incident reported in your area (Brooklyn, NY)
Remote diagnosis:
- Router powered: Yes
- Fiber connection: OK
- 5GHz WiFi: Active
- 2.4GHz WiFi: Disabled (abnormal)
Problem identified: Your 2.4GHz WiFi band got disabled. Most devices use this band.
Solution (30 seconds):
- On your router, press the WiFi button (right side, WiFi icon)
- Hold for 5 seconds until the green light blinks
- Release
The 2.4GHz WiFi should reactivate. Your devices will reconnect automatically within 2 minutes.
Is it working now?"
Impact: 80% of WiFi issues resolved without a call.
2. New TV Box Setup
The problem: "I can't install my new TV box"
The RAG solution:
Customer: "I received my new TV box but I can't connect it"
Assistant: "I'll guide you step by step.
Your new TV box: UHD TV Box (reference: TVB-UHD4) Your TV: [Not specified - I'll guide you for both cases]
Step 1 - Connections:
On the back of the TV box, you have 4 ports:
- Power cable (round, black) -> Wall outlet
- Ethernet cable (square, transparent) -> Black port on your router
- HDMI cable (flat, black) -> HDMI port on your TV
- Optical port (optional) -> If you have a soundbar
Check: Are all cables connected?
Step 2 - Startup:
- Turn on your TV
- Set your TV to HDMI source (Source or Input button on your TV remote)
- The box should display "Starting up..."
What do you see on your TV screen?
A) "Starting up" or operator logo B) Black screen C) "No signal" D) Other message"
Impact: Self-installation rate +45%.
3. Phone Lost Network
The problem: "My phone has no network"
The RAG solution:
Customer: "My iPhone has no service for 2 days"
Assistant: "I'll help diagnose the issue.
Your plan: Unlimited 100GB (active, due 11/28) Payment: Up to date Last network activity: 52 hours ago
Coverage check: Your address (Manhattan) has 4G/5G coverage - No incident reported.
Diagnosis: Your line is active but your phone can't connect.
Possible causes (by probability):
- SIM card poorly inserted (35% of cases)
- Airplane mode on (20% of cases)
- Defective SIM card (25% of cases)
- Phone issue (20% of cases)
Step 1 - Quick checks:
On your iPhone, check the top right:
- Is there an airplane icon? -> If yes, disable airplane mode
- Are there signal bars? -> If no, continue
Step 2 - Network reset:
- Go to Settings > General > Transfer or Reset
- Tap "Reset Network Settings"
- Enter your passcode
- Confirm
Your iPhone will restart and search for network.
If still no service after 5 minutes: Your SIM card is probably defective. I can send you a new SIM for free, delivered within 48h.
Would you like me to send it?"
Impact: Unnecessary SIM shipments -60%, first contact resolution +55%.
4. Slow Internet Connection
The problem: "My connection is very slow"
The RAG solution:
Customer: "Internet has been slow for a week, it's unbearable"
Assistant: "I understand, let's analyze your connection together.
Your plan: Fiber 1Gbps Your equipment: Router Model 5 (2 years old)
Real-time speed test:
- Download: 87 Mbps (expected: 900+ Mbps)
- Upload: 245 Mbps (expected: 500+ Mbps)
Diagnosis: Your speed is abnormally low for a fiber connection.
Cause analysis:
- WiFi connection: You're connected via WiFi, not cable
- Estimated router distance: >30 feet or obstacles
- Recommendation: Test with Ethernet cable for comparison
- WiFi congestion: 23 devices connected to your router
- That's a lot! Some may be saturating bandwidth
- Top 3 consumers: Smart TV (streaming), PS5, Desktop PC
- WiFi channel: Your router uses a very congested channel
- 12 neighbor WiFi networks on the same channel
Proposed solutions:
Solution 1 - Channel change (automatic): I can change your router's WiFi channel remotely. Takes 2 minutes and your devices will reconnect automatically.
Solution 2 - WiFi extender (if large space): Your home seems large. A WiFi extender would improve coverage. Available free with your plan.
Solution 3 - Prioritization (optional): I can configure priority for your important devices (work PC for example)
Which solution would you like to start with?"
Impact: Satisfaction on speed issues +40%.
5. Unexpectedly High Mobile Bill
