Great customer service from Julia!

We have had two Tello lines for the past few years, and the service has been great. Recently we were in Brazil had some trouble getting my wife's phone to recognize the American Tello number to make and receive US calls, so we called Tello customer service to see if they could help. We were very fortunate to have gotten Julia Infante on the line! She was very patient, knew exactly what to do to fix our complicated problem, and everything is good! She is a real professional, and was also very pleasant to talk to. Great job Julia!

These people always are the best

Tello SIM Review

Tello SIM Review – Affordable Price & Reliable Network in the US I recently used a Tello Mobile SIM during my time in the United States, and I was genuinely impressed with the overall experience. Very affordable pricing: Compared to major carriers like AT&T, Verizon, or T‑Mobile, Tello is significantly cheaper. You can customize your own plan and only pay for what you actually need. It’s perfect for travelers, short‑term business trips, or anyone looking to save money. Stable and reliable network: Since Tello operates on the T‑Mobile network, the 4G/5G coverage is solid. Internet speed is smooth, calls are clear, and I rarely experienced any connection issues. Easy activation: Buying an eSIM and activating it takes just a few minutes. No contracts, no hidden fees. Flexible plans: You can change or adjust your plan anytime with just a few clicks. → Final verdict: If you need a budget‑friendly, flexible, and stable SIM card while staying in the US, Tello is definitely a great choice.
