Spoke to customer service rep Michael

Spoke to a representative named Michael. He helped guide me through the process of resolving my issue, and his customer service skills were PHENOMENAL. He helped guide me through a tough tech issue, and he showed a great deal of patience and genuinely wanted to help. I was very impressed considering that most reps with other companies just want to get you off the phone as soon as possible. Michael's the best customer service rep I've ever interacted with. (And for the record, I've spoken with 2 other Tello reps, and they were great as well, so props to Tello!)

We have been with Tello for almost 2…

We have been with Tello for almost 2 years now. The pros: we haven't had any service interruptions and I can email support and not be stuck on the phone all day. I have as good of coverage as I did with AT&T. Cons: sometimes the data does not penetrate into certain buildings where I had coverage before and the unlimited plan is not really unlimited. I thought it was supposed to just slow down at certain limit, but we were charged for 1 GB of data on the unlimited plan.

Most friendly over the phone customer…

Most friendly over the phone customer service I have seen at all. Best provider for travellers to USA. Despite they don't promise refunds, they often do refund for unused phone service at later day. I've got refunds three times over the years... Compartable service with international phones. Signal may be weak in some rear areas but, considering super low price, their service worth of every penny.
