Perfect service for four years

We started using Tello several years ago, for two phones. We appreciate the low prices & the flexibility to personalize our plans to meet different needs for data. Never had a problem with Tello! They're trustworthy & reliable, and seem like really nice people.

Good T-mobile voice coverage, slow sms

Good T-mobile voice coverage. Occasional text message delivery have been delayed by as much as several hours although usually fast.

Tello's prices and communications are excellent

Tello's prices and communications are excellent. I never have to wonder when I'm going to get charged or how much my bill will be. Everything just stays the same which is exactly how I like it. My only complaint is with the actual signal. Since I've been on Tello's network, I have more connectivity issues when in urban areas that are on a more modern radio standard.
