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.

Out of service for four days

I had been without phone service for 4 days. An employee who I spoke to at about 1030PM Saturday night was able to talk me through getting my phone working again. He was knowledgeable and patient. I wish I had asked his name. But he is a great asset to Tello. I was at my wits end being unable to type in all the PUK codes I could and nothing worked. He was able to walk me through getting my phone working again. It was on an APPLE SE phone first generation. I have had it since it was new. And it still looks new as it has always been in a case. I did not want to give it up. But this Tello employee was the most helpful person I have ever come into contact with.

Holy mackerel!!

Holy mackerel!!! One of the best customer service/support I have ever experienced. Shaun F and the prior representatives were extremely helpful and patient, with an old guy like myself who has a lot of anxiety when it comes to "technology". I couldn't ask for more professionalism and care. Customer service was available 24/7 and again, each time was awesome. I cant say enough about Tello, I highly recommend their service.
