How to Start an ISP in Pakistan
A structured playbook for launching an Internet Service Provider in Pakistan — from feasibility to first live subscribers.
Starting an ISP looks like buying hardware and reselling bandwidth. In practice, it's a long list of engineering, business and operational decisions — each of which affects churn, cost and how fast you can grow.
This article outlines a practical path that has worked for many Pakistani operators: from the earliest feasibility questions to a live network with real subscribers and a clean operational baseline.
1. Feasibility & Sizing
The most important first step is deciding scope. Are you covering a housing society, a town, or a metro area? What's realistic in the first 12 months? Underestimating gets you stuck; overestimating burns capital.
- Coverage area & density
- Target subscriber count (year 1 & year 2)
- Service mix (residential, SME, enterprise)
- Backhaul & upstream options
- Competitive pricing bands in your area
2. Topology & IP Design
This is where architecture matters more than any single vendor. Core, distribution and access should be planned together — including how PPPoE termination, RADIUS AAA and monitoring integrate.
- Core routing (BGP if you're peering, OSPF internally)
- PPPoE / IPoE decision
- IPv4 blocks & IPv6 plan
- Redundancy targets
- Segmentation for management traffic
3. Hardware Selection
Pick devices you can actually operate. A powerful OLT that nobody in-house understands is a liability. The right OLT is the one you can commission, monitor and troubleshoot on day 400, not just day 1.
- OLT (VSOL, Huawei, ZTE, FiberHome, BDCOM, C-DATA, HSGQ)
- ONT strategy — vendor and Wi-Fi standard
- MikroTik CCR or vendor router for BNG
- Managed switches with 10G/25G uplinks
- Servers for RADIUS, NMS, ACS, billing
4. Software Stack
The operational layer around your network is where compounding value lives — RADIUS, billing, monitoring, ACS. This is what turns an installer into an ISP.
- Billing / CRM (in-house or third-party)
- RADIUS (FreeRADIUS or vendor)
- NMS (LibreNMS, Zabbix, vendor)
- TR-069 ACS for remote CPE
- Documentation & runbook
5. Deployment & Launch
By this point most decisions are made. Deployment is about executing them — and about writing everything down so that day 2 support is possible.
6. Monitoring & Scale
Once you're live, the priority shifts to visibility and repeatable operations. Alerts should reach humans, capacity should be tracked, and every new subscriber should follow the same provisioning flow.
