Great phone service for those abroad

I recently transferred my Tello e-sim from one phone in Poland to another. This service is the best way to keep a U.S. phone line in operation during long trips abroad. This is my iphone's second line. Not only can I get text messages from the U.S. (for example, from my bank during a security check), but if I have Wi-Fi access, I can call friends and have my number show up normally.

Number porting for two numbers was flawless

Number porting for two separate numbers from two different providers has been flawless. Steps given for obtaining a number and performing port provided all required details. Service has been great, with comparable coverage of previous providers. We've not experienced any outages or notable slowdown in service. First number has been with Tello for 6 months. Second number was ported in the last month.

Perfect for International Travelers and Expats

In addition to the US, I have been utilizing Tello in South America (Brazil), and Tello has met or exceeded all expectations. First and foremost, the receipt of SMS messages for TFA, via either WiFi Calling or International Roaming, has been seamless, in addition to its other functionalities. And to top it off, Customer Service is of a consistently high caliber and always helpful. Very highly recommended!
