Best ISP in Colombia for 2026
Claro and Tigo are Colombia's two largest ISPs. Both offer fiber and HFC cable in Bogotá, Medellín, Cali, and Barranquilla. ETB remains the dominant fiber provider in Bogotá specifically. Fiber penetration is growing but cable is still the primary technology in many markets. Updated 2026-04-27.

ISP breakdown
1. Claro Colombia
Claro Colombia is the country's largest ISP by subscriber count. Fiber and HFC cable in Bogotá, Medellín, Cali, and other major cities. Expanding FTTH rollout is the main 2025–2026 growth story.
2. Tigo Colombia
Tigo is a major challenger ISP in Colombia. Strong HFC cable network and growing fiber footprint in major Colombian cities. Competitive pricing and good peak-hour cable speeds where available.
How to pick the right plan in Colombia
- Match the plan to actual usage, not headline speed. A 1 Gbps plan only matters if multiple people stream 4K, run cloud backups, or transfer large files at once. For a couple of streams and video calls, 200–500 Mbps is plenty.
- Prioritise upload symmetry if you work from home. Fibre plans in Colombia are usually symmetric; legacy DSL and cable hybrids are not. Asymmetric plans cripple video calls, cloud sync, and uploading large files even when download looks fast.
- Watch for promotional vs renewal pricing. Most ISPs advertise a 6–12 month introductory rate that doubles afterwards. Check the post-promo price before signing — that's what you actually pay long-term.
- Check the router they ship. A flagship plan on a 4-year-old ISP-issued router still tops out at the router's Wi-Fi 5 speed. If you have Wi-Fi 6/6E devices, ask whether you can BYO router or upgrade the issued model.
- Read the fair-use policy. Some plans deprioritise traffic after a monthly threshold (often 1–3 TB) or during peak hours. The fine print is where the real bottleneck hides.
What to test after installation
Within the first 14 days of a new connection, run a wired speed test at three different times of day (early morning, evening peak, and late night). If sustained throughput is consistently below 80% of the advertised plan speed on a wired connection, escalate to your ISP within the cooling-off window — most providers in Colombia are required to fix or release you from the contract.
Also test ping and jitter — see our guides on latency, jitter, and packet loss to interpret the numbers.
Frequently asked questions
Fibre vs cable vs 5G fixed wireless — which is best?
Fibre (FTTH) wins on reliability, symmetric upload, and consistent latency. Cable can hit similar download speeds but uploads are typically 10–20% of download and contention is higher at peak hours. 5G fixed wireless is improving fast and can be a strong option in areas without fibre, but performance varies with cell-tower load and weather.
Does the contract length actually matter?
Yes — long contracts (12–24 months) usually get the better headline price, but make it expensive to leave if service quality deteriorates or a faster competitor launches in your area. Read the early-termination fee before signing.
Is the ISP-supplied router good enough?
It depends. Newer Wi-Fi 6 / Wi-Fi 6E gateways from major ISPs are usually fine for typical homes. Older Wi-Fi 5 (802.11ac) units bottleneck plans above ~400 Mbps over wireless. If you can't change the router, hardwire your most important devices over Ethernet to bypass the wireless ceiling.
How to check ISP availability at your address
ISP availability varies at the address level — two houses on the same street can have different technology (fiber vs cable vs DSL) available. Always check each provider's address-level tool, then run a speed test after installation to verify real-world performance.
How does Colombia's broadband quality compare between major cities and smaller towns?
Bogotá, Medellín, Cali, and Barranquilla are by far the best-served cities in Colombia, with multiple providers offering fiber and HFC cable plans that can reach 300–500 Mbps. Medellín in particular has invested in digital infrastructure and has a reputation for above-average connectivity quality relative to its size. In secondary cities such as Bucaramanga, Cartagena, Manizales, and Pereira, Claro and Tigo offer cable and some fiber options, but plan tiers are typically lower and peak-hour performance is more variable. In smaller municipalities and rural areas — particularly in Pacific Coast departments, the Llanos, and Amazonia — fixed broadband options are extremely limited, and mobile data (4G LTE) is often the primary internet source. Colombia's MinTIC has prioritized rural connectivity through the Zonas Digitales program, which has deployed public Wi-Fi hotspots in underserved municipalities, but dedicated home broadband in these areas remains scarce.
