Good service generally

Good service generally. Drops calls less than AT&T and costs 1/3 as much. Customer service is nice. Not always technically knowledgeable and it can be slow going to wait for them to figure out technical issues, but they do try and genuinely want to help. Would recommend overall.

Helpful customer service

I called Tello customer service for advice on how to manage a feature of my plan. The call agent was courteous, patient, kind, and very helpful. She also informed me that Tello customer service is available 24/7, 365 days a year. What's more, I didn't have to wait long in a calling queue to get my call answered. Low cost and great customer service make Tello a great company, on top of their actual great product-- which is excellent call clarity and terrific signal coverage which equals that of their much pricier competitors (whose customer service is lacking).

Calls to Tello always rate at least 5…

Calls to Tello always rate at least 5 stars! Johyse was very helpful and professional. It is always a surprise when customer service representive for large companies speak english clearly and correctly. I have been with Tello for a while and could not be happier. And the Black Friday Sale didn't hurt ether.
