Tello is very good

Tello is very good。 I have used it for many years, and my only worry is that if the bad guy knows my email and phone number, he can change my password and make it his.

The reason I gave 4 stars instead of 5…

Very good product, with flexible plan options and great quality. I especially appreciate the calling app, which solves the issue of poor call quality caused by weak carrier signal. Calls made through the Tello app are very clear. Also, Tello’s choice of a blue-themed design is very pleasant to look at. The reason I gave 4 stars instead of 5 is because Tello tends to suspend accounts too easily, often without sufficient reason, and once an account is suspended, there is no way to appeal or recover it. This is the only downside so far.

I absolutely love Tello

I absolutely love Tello! You can get to a human being, who you can understand, quickly and easily if you call their customer service. And they are able to fix issues on the first call.
