Worth Every Penny
I travel to the USA a fair amount, having a dedicated US chip makes reservations, paying for parking and lifein general easier. Tello are amazing, I buy an E sim prior to leaving and it works wonders on arrival, I can even use it in the UK over WIFI to call and make reservations from the UK before I leave. It is the best circa £25 I spend while away, unlimited texts calls and 50GB of data. I still take my UK mobile but turn this off during the night and use my Tello mobile as an emergency number should I be needed urgently at an unreasonable hour.

Olivia at Tello is AMAZING!
I just had the greatest customer service experience with Olivia at Tello. She was super helpful, patient, and kind in guiding me through the eSIM setup process after I had accidentally messed it up at the beginning and lost all phone connection. She made a very stressful situation an easy one to fix in less than 15 minutes. Thank you so much!
Very best company I would recommend.
Love Tello
Love Tello! The service is reliable, the pricing is excellent, and there are no confusing contracts or unnecessary fees. It’s easy to manage my plan, and I can change it whenever I need to. Great value, great service, and refreshingly simple. Highly recommend!
3 LINES with Tello and 611 never answers NO CUST SERVICE
We have THREE tello phone lines and 611 customer service is always "NOT AVAILABLE" Horrible and dangerous when you need help. Can no longer recommend tello

Works using a ETROSS VolTE 8838 unit. Tello being T-Mobile sim, etross manufacturer did not know if it would work OK, because of testing only with ATT. Hooked up the ETROSS and it works with TELLO

Huge shoutout to Sebastian
Huge shoutout to Sebastian! He was incredibly knowledgeable about the Tello process and patient throughout the call. During troubleshooting, he walked me through each step clearly and methodically, making the process easy to follow. His communication was excellent, and he was friendly, professional, and easy to talk to. I truly appreciate the outstanding support he provided and am grateful that Sebastian was the one who assisted me.
The best customer service provided by any company!
I spoke to your customer service agent Rossio. She is very respectful and quickly understood my concern and helped resolve it. She also kindly emailed me additional information regarding international travel and how I could use tello service for my calls abroad. I would like to thank Tello for having good customer service agents as I have always been answered and taken care of when I have called Tello support. Also, it is excellent that one doesnt have to go through the automated responses and options before being connected to a live agent. Appreciate it! Once again a big Thank you!
I am really disappointed with Tello
I am really disappointed with Tello. In our group, there are people who have esims from two additional providers. Throughout large portions of California, they had connectivity and we didn't. In addition, it didn't work at all on one of the phones. The same phone worked on different a different network. Ubigi was much better. It is strange that they reply with a clear mistruth. We had 6 phones on three different networks, only Tello failed to work.

Dear customer, We appreciate your feedback and would like to clarify your account details. The connectivity issue you experienced was likely caused by a brief nationwide outage some days ago, which was fully resolved within a few hours. Normal service usage has since resumed across your active lines. However, if you are still experiencing any issues, please contact our Customer Service team, they are available 24/7. Regarding the line that did not work at all, our records indicate that the specific phone being used is incompatible with our network. We sent an email with further details—please check your inbox or spam folder to view our response. You can also verify device compatibility anytime using our online Device Checker. Thank you, Tello
