In the bustling digital landscape of 2025, a reliable internet connection isn’t just a luxury—it’s a necessity. Whether you’re streaming 4K content, gaming online, or managing a work-from-home setup, your broadband plan needs to deliver speed, stability, and value. Enter Alliance Broadband’s QTR 400 400Mbps plan, a flagship offering that promises blazing-fast speeds and premium features, particularly for users in Kolkata and other parts of India. But does it live up to the hype?
In this comprehensive, no-stone-unturned review, I’ll dive deep into every aspect of the QTR 400 plan—pricing, speed performance, customer service, installation process, add-ons, and even the nitty-gritty details like network stability during peak hours. By the end of this post, you’ll know whether the QTR 400 is the right fit for your internet needs or if you should look elsewhere. Let’s get started!
What Is the Alliance Broadband QTR 400 Plan?
Alliance Broadband, a Kolkata-based Internet Service Provider (ISP) with a Unified License Category A from the Department of Telecom, Government of India, has been a trusted name in the broadband industry since 2003. Known for its competitive pricing and high-speed plans, Alliance has carved a niche, especially in eastern India. The QTR 400 plan is one of its premium quarterly offerings, boasting a headline speed of 400Mbps and a suite of benefits tailored for heavy internet users.
The QTR 400 is a quarterly plan, meaning you pay upfront for three months of service, which often comes with cost savings compared to monthly billing. It’s marketed as an ideal choice for households with multiple devices, small businesses, or anyone who needs robust internet for bandwidth-intensive tasks like streaming, gaming, or large file transfers.
But what exactly does the QTR 400 offer? Let’s break it down step by step, starting with the most critical factor: pricing.
Pricing: Is the QTR 400 Worth Your Money?
When choosing a broadband plan, pricing is often the first thing we look at. After all, no one wants to overpay for internet that doesn’t deliver. The QTR 400 plan is positioned as a premium yet affordable option, but let’s dissect the costs and value.
Base Pricing and Payment Structure
As of May 2025, the QTR 400 plan is priced at approximately ₹2,500 for three months (including GST). This breaks down to roughly ₹830 per month, which is competitive for a 400Mbps plan in India. The quarterly billing structure means you pay upfront, which might feel like a hefty initial investment but saves you from monthly hassles.
Compared to competitors like Jio Fiber, Airtel Xstream, or BSNL Bharat Fibre, the QTR 400’s pricing is in the mid-to-high range for 400Mbps plans. For instance:
- Jio Fiber: Offers a 300Mbps plan for around ₹1499/month and includes some OTTs and digital-feed TV.
- Airtel Xstream: Prices its 300Mbps plan at ₹1599/month which includes some OTTs and 350+ TV Channels.
- BSNL Bharat Fibre: Often cheaper but struggles with inconsistent speeds and outdated infrastructure in many areas.
Alliance’s QTR 400 stands out because it doesn’t impose a Fair Usage Policy (FUP) limit, meaning you get unlimited data at 400Mbps without speed throttling after a certain data cap—a big win for heavy users.
Hidden Costs and Additional Fees
While the base price is straightforward, there are a few potential add-ons and fees to consider:
- Installation Charges: For new customers, Alliance may charge a one-time installation fee of ₹1,000–₹1,500, depending on your location and whether you opt for a router. This is often waived during promotional periods, so keep an eye out for offers.
- Router Costs: The QTR 400 plan requires a high-performance router to maximize its 400Mbps potential. Alliance provides a dual-band Wi-Fi router for free in some cases, but you might need to purchase one (₹1500–₹2,000) if you want a premium model.
- OTT Add-Ons: Alliance offers optional OTT subscriptions (like Netflix, Amazon Prime, or regional platforms) as add-ons, which can increase the cost by ₹100–₹500 per month, depending on the bundle.
Value for Money
At ₹830/month for 400Mbps with unlimited data, the QTR 400 is a solid deal for power users. The lack of FUP is a major advantage, especially for households with multiple 4K streaming devices, gamers, or professionals handling large cloud-based projects. However, if you’re a light user who doesn’t need 400Mbps (e.g., basic browsing and HD streaming), Alliance’s lower tier plans like the 40Mbps or 140Mbps options might offer better value.
Speed Tests: Does the QTR 400 Deliver 400Mbps?
The headline speed of 400Mbps sounds impressive, but real-world performance is what matters. To evaluate the QTR 400, I conducted multiple speed tests over a week, using both wired (Ethernet) and wireless (Wi-Fi) connections. Here’s what I found.
Testing Methodology
- Devices: Laptop with and Intel WiFI-6 Wi-Fi Card, Galaxy S23 Ultra.
- Router: Asus RT-AX86U PRO.
- Test Platforms: Ookla Speedtest, Fast.com, and Google’s Internet Speed Test.
- Time of Day: Tests were conducted during peak hours (7–10 PM), off-peak hours (2–4 AM), and midday (12–2 PM).
- Location: A residential area near Kolkata with Alliance’s fiber-to-the-home (FTTH) infrastructure.
Wired Speed Test Results
Using the ethernet connection from the Asus router, the QTR 400 consistently delivered speeds close to (or even more in some cases) the advertised 400Mbps:
- Ookla Speedtest: 420-440Mbps download, 410-415Mbps upload, 5–10ms ping.
- Fast.com: 400-410Mbps download, 390-400Mbps upload.
- Google Speed Test: 395-400Mbps download, 380-390Mbps upload.
These results are excellent, with download and upload speeds hovering within 5–10% of the promised 400Mbps. The low ping (3-5ms) is a boon for online gamers and video conferencing, ensuring minimal lag.
Wireless Speed Test Results
Wi-Fi performance depends on factors like router quality, distance from the router, and interference. Using the 5GHz band at a distance of 5–10 meters:
- Ookla Speedtest: 410-415Mbps download, 420–430Mbps upload, 8–12ms ping.
- Fast.com: 400-410Mbps download, 390-400Mbps upload.
- Google Speed Test: 395-400Mbps download, 380-390Mbps upload.
On the 2.4GHz band (better range but slower speeds), results dropped to 80–120Mbps, which is expected due to the band’s limitations. For optimal performance, stick to the 5GHz band or a wired connection.
Peak vs. Off-Peak Performance
During peak hours (7–10 PM), speeds dipped slightly:
- Wired: 380-390Mbps download, 370-380Mbps upload.
- Wireless (5GHz): 360-390Mbps download, 380-390Mbps upload.
The drop is a bit noticeable but not drastic, indicating Alliance’s network handles congestion pretty well. Off-peak hours (2–4 AM) showed more than maximum speeds, often exceeding 400 Mbps on wired and connections.
Real-World Use Cases
- 4K Streaming: Streaming Netflix and Amazon Prime in 4K Ultra HD on three devices simultaneously was seamless, with no buffering.
- Online Gaming: Games like Call of Duty: Warzone and Valorant ran smoothly, with ping times below 15ms on Indian servers.
- File Downloads: A 10GB file downloaded in under 4 minutes on a wired connection and on Wi-Fi (5GHz).
- Video Calls: Zoom and Google Meet calls in 1080p were crystal-clear, even with multiple tabs open.
The QTR 400 delivers almost the entirety of its advertised 400Mbps on wired connections and Wi-Fi (5GHz), which is impressive for a residential plan. The lack of FUP ensures consistent speeds regardless of data usage, making it ideal for heavy users. However, your router and device capabilities play a big role in maximizing performance.
Customer Service: How Responsive Is Alliance Broadband?
A great broadband plan is only as good as the customer service backing it. Alliance Broadband has a mixed reputation in this area, so I put their support to the test by contacting them through multiple channels.
Contact Options
Alliance offers several ways to reach their support team:
- Phone: A dedicated helpline – 1800-1200-300
- Email: abspl@alliancebroadband.co.in.
- Online Portal: A ticketing system at servicedesk.alliancebroadband.in.
- WhatsApp: A relatively new option for quick queries.
My Experience with Customer Support
Installation Query (Phone)
When I called to inquire about installation for the QTR 400, the representative was polite and knowledgeable. They explained the process, confirmed availability in my area, and activated the plan on my account after the current plan expired. They also sent me the receipt via WhatsApp. The entire process took around 10 mins.
Technical Issue (Online Portal)
To test their troubleshooting, I raised a ticket about intermittent Wi-Fi drops (a simulated issue). The portal was user-friendly, and I received an acknowledgment email instantly. A technician called me within an hour and on call, he performed some tests from my laptop via AnyDesk. The issue was resolved within an hour or so.
Landline Connection Clarification (Email)
I emailed to ask about landline calling service. The response took hardly a few minutes, which is pretty reasonable but a tad bit slower than phone or WhatsApp. The reply was detailed, with a clear breakdown of the process of activation of landline calling.
WhatsApp Support
I messaged their WhatsApp number to ask about plan upgrades. The response came within 15 minutes, and the agent was proactive, offering to schedule a call with a senior representative to discuss technical details of the plans.
Strengths of Alliance’s Customer Service
- Multiple Channels: Phone, email, portal, and WhatsApp provide flexibility.
- Knowledgeable Staff: Representatives were well-versed in technical and billing queries.
- Quick Resolution: Most issues were addressed within 2 hours.
- Local Expertise: Being a regional ISP, Alliance’s team understands Kolkata’s infrastructure and user needs.
Weaknesses
- Response Time Variability: Phone and WhatsApp are faster than email or the portal.
- Holiday Delays: During national holidays, phone as well as email wait times wait times can stretch to 10–15 minutes.
- Technician Scheduling: While my experience was smooth, some online reviews mention delays in technician visits.
Customer Service Verdict
Alliance Broadband’s customer service is above average for a regional ISP. They’re responsive, professional, and equipped to handle most issues, but response times can vary depending on the channel and time of day. For urgent issues, stick to phone or WhatsApp.

Installation and Setup: What to Expect
Getting started with the QTR 400 plan involves a straightforward but sometimes time-sensitive installation process. Here’s how it went for me and what you should know.
Booking the Installation
After subscribing online via Alliance’s helpline, I received a confirmation email with a tentative installation date of next day. A representative called to verify my address and schedule a technician visit.
Technician Visit
The technician arrived on time, equipped with a fiber optic cable, a router, and tools for setup. The process took about an hour:
- Fiber Connection: The technician ran a fiber cable from the nearest junction box to my home.
- Router Setup: They configured the provided dual-band router, ensuring both 2.4GHz and 5GHz bands were active.
- Speed Test: A quick speed test confirmed 400Mbps on Wi-Fi, which was my chosen plan.
The technician was professional, answered my questions and even took no installation charges.
Potential Hiccups
- Router Performance: The provided router is decent (TP-Link XC220-G3V), but heavy users might want a high-end model for better range and performance.
- Scheduling Delays: In busy periods, installation team visit can take 2-3 days, especially in busy areas.
The installation process is smooth if you’re in a fiber-ready area. Alliance’s technicians are competent, but scheduling and wiring issues can cause minor delays. Plan ahead and confirm FTTH availability to avoid surprises.
Add-Ons and Features: What Else Does QTR 400 Offer?
Beyond raw speed, the QTR 400 plan includes several features and optional add-ons that enhance its value.
Unlimited Data with No FUP
As mentioned, the QTR 400 offers unlimited data without a Fair Usage Policy. This is a game-changer for:
- Streamers who binge 4K content on Netflix, Disney+, or YouTube.
- Gamers downloading massive updates (e.g., 100GB+ for AAA titles).
- Professionals uploading large files to cloud services like Google Drive or Dropbox.
OTT Subscriptions
Alliance sweetens the deal with optional OTT add-ons. For an extra ₹100–₹500/month, you can bundle platforms like:
- Netflix (Standard or Premium plans).
- Amazon Prime Video.
- SonyLIV, ZEE5, or regional platforms like Hoichoi.
These bundles are cost-effective compared to standalone subscriptions, especially for households that already use multiple streaming services.
Static IP Option
For businesses or advanced users, Alliance offers a static IP address (SNAT IP) for an additional fee (₹3,500/year). This is useful for:
- Hosting servers (e.g., gaming or web servers).
- Remote access to home devices.
- Enhanced security for certain applications.
Wi-Fi 6 Router Compatibility
The QTR 400 is optimized for Wi-Fi 6 routers, which support higher speeds and better device handling. If you use Alliance’s provided router, it’s Wi-Fi 6-capable, ensuring you get the most out of the 400Mbpe speed.
The QTR 400’s unlimited data and OTT add-ons make it versatile for entertainment and productivity. The static IP option is a niche but valuable feature for tech-savvy users. However, the cost of add-ons can add up, so choose only what you need.
Reliability and Network Stability
A 400Mbps plan is useless if the connection drops or slows down unexpectedly. To assess the QTR 400’s reliability, I monitored its performance over a month.
Uptime
The connection was stable 99% of the time, with only one brief outage (15 minutes) due to scheduled maintenance, which Alliance notified me about in advance. This is better than some national ISPs, which can suffer from frequent downtimes in certain areas.
Peak Hour Performance
As noted in the speed tests, peak-hour congestion caused a 5–10% speed drop, but the connection remained usable for all tasks. Streaming, gaming, and browsing were unaffected, even with 10 devices connected simultaneously (including IoT devices).
Weather Impact
Kolkata’s monsoon season can wreak havoc on internet infrastructure. During heavy rain, the QTR 400 maintained stable speeds, all attributing to to Alliance’s FTTH setup, which is less prone to weather-related disruptions than copper lines.
The QTR 400 is highly reliable, with minimal downtime and consistent performance, even during peak hours or adverse weather. Alliance’s fiber infrastructure is a key strength here.
Who Is the QTR 400 Plan For?
The QTR 400 is a premium plan, so it’s not for everyone. Here’s a breakdown of who it suits best:
Ideal Users
- Heavy Streamers: Households with multiple 4K streaming devices will love the unlimited data and high speeds.
- Gamers: Low ping and fast downloads make it great for competitive gaming.
- Work-from-Home Professionals: Reliable speeds and upload performance are perfect for video calls, cloud work, and large file transfers.
- Small Businesses: The static IP option and high bandwidth support small-scale servers or office needs.
Who Should Look Elsewhere?
- Light Users: If you only browse, check emails, or stream in HD, a 40-100Mbps plan will save you money.
- Budget-Conscious Users: The quarterly payment and potential add-on costs might be too steep for some.
Comparing QTR 400 to Competitors
To put the QTR 400 in context, let’s compare it to similar plans from top ISPs:
Jio Fiber (300Mbps, ₹1,499/month)
- Pros: Bundled OTT subscriptions with Live Digital TV, nationwide coverage.
- Cons: Lower speed (300Mbps), FUP limits in all plans, horrible customer service.
Airtel Xstream (300Mbps, ₹1,599/month)
- Pros: Reliable network, excellent customer service, OTT and IPTV with 350+ channels.
- Cons: Higher cost, FUP in all plans, limited availability in smaller cities.
BSNL Bharat Fibre (300Mbps, ₹1,799/month)
- Pros: Wide rural coverage, higher FUP than competitors (6.5TB vs 3.3TB), OTT and IPTV in most states.
- Cons: Inconsistent speeds, outdated infrastructure, slower support.
The QTR 400 holds its own with unlimited data, competitive pricing, and strong regional performance, but Airtel’s customer service and Jio’s OTT bundles might sway some users.

Final Verdict: Should You Get the QTR 400 Plan?
After spending a month with the Alliance Broadband QTR 400 400Mbps plan, I can confidently say it’s one of the best high-speed broadband options in Kolkata and surrounding areas. The near-400Mbps speeds, unlimited data, and reliable performance make it a powerhouse for heavy users, whether you’re streaming, gaming, or working from home. The customer service is responsive enough to handle most issues, and the OTT add-ons add extra value for entertainment buffs.
However, the quarterly payment structure and potential add-on costs might deter budget-conscious users. If you don’t need 400Mbps or live outside Alliance’s coverage area, consider lower-tier plans or competitors like Jio or Airtel.
For power users in Kolkata, the QTR 400 is a no-brainer. It delivers on its promises and offers a premium internet experience at a reasonable price. If you’re ready to level up your broadband game, the QTR 400 is worth every penny.
