Tello is the budget answer to the business phone question: a no-contract carrier running on a major nationwide 5G network where you build the plan yourself, picking exactly the data and minutes each line needs. Plans start at $5 a month and even the unlimited option is $25, which makes equipping a small team dramatically cheaper than the big carriers. Every calling plan includes free calls to 60+ countries, unlimited text, hotspot support, and eSIM activation in minutes, so a new hire can be live on a work number the same day. The trade-offs are honest ones: support is not the white-glove enterprise kind, data on the unlimited plan slows after 50 GB, and as an MVNO your traffic can be deprioritized behind the host network's own customers in congestion. For a solo operator or small team that needs reliable work lines without a contract or a carrier-store ordeal, the value is hard to argue with.
Tello scores 8.2 out of 10 overall. Its strongest area is reflected in the breakdown below, and the main tradeoff to weigh is that unlimited plan slows after 50 gb of high-speed data.
Each criterion is scored 1-10 using the same standardized framework across every product.
