Great customer service experience

Dana was exceptionally clear in explaining the steps to resolve the issues I was having with moving my phone number from a dead iPhone to another iPhone.

No mobile data while roaming on Tello--Resolved!

I am roaming in South Korea and have had problems connecting to mobile data, meaning I couldn't receive MMS's or connect to the internet at all. After trying to troubleshoot with forum discussion suggestions, I sent an email to Tello's customer service. Over the course of solving the problem, I was contacted by 3 different representatives who each provided key information on solving my problem: Alejandro, Samuel, and Mihail. Key information provided like roaming Tello APN settings and manually choosing a network were essential in confirming my roaming status and resolving my issue. Replies and troubleshooting messages were detailed and swift. I've had a great experience with Tello's customer support (and especially with Alejandro and Mihail) and I wouldn't hesitate to reach out again if I have another concern. They are awesome!

Purchase was fine but a waste of money.

Purchased $20 worth of additional data for my wife’s phone. The transaction was easy and the data was immediately available. The reason I am only giving 4 stars is because I previously bought $20 “pay as you go” for my phone because I was traveling to Canada and wanted to use my phone. I did, using exactly $1.15 for international roaming, leaving an unused balance of $18.95. I could not use that money to buy data for my wife and I doubt I will be traveling internationally again. I cannot apply the $18.95 to my monthly charge so I guess I will just have to kiss that money goodbye. It’s a bit of a shame.
