Great company

The fact that I could reach a 'Customer Service Person' rather than recorded messages was excellent. Your customer service personnel are the most helpful, professional and accommodating people I have had the pleasure of dealing with. Yes, I had an issue with my Tello sim card but your customer service lady had it sorted in no time at all. Lovely people to deal with.

Great Company, Great Service

Amazing service. Simple, no ads or spam mail, super cheap, and I get exactly what I want. Makes me feel like big phone companies are a scam. I would recommend Tello to anyone.

New phone set up super easy

I just got a new unlocked phone, and the set up was, overall, super easy, IMEI number, plan selection, Tello cancelled my previous phone's plan. I didn't have to ask for anything... I am so happy I found Tello a few years ago... Great plan prices, the Service. Other carriers would charge extra for some of what Tello offers, but not Tello. They just show up and deliver what they promise.

Josue was so helpful

Josue was so helpful. I wasn't clear on what I wanted and he was able to give me information and ask me the right questions in a patient manner until I made a decision on a product and plan. I appreciated his going the extra mile and giving me suggestions or other options to consider. I was initially thinking of using the SIM for one month but am now interested in keeping it and using it during my travels. As an HR Director, I recommend you keep a great employee like Josue. In fact give him a promotion and a raise. Such employees need to be recognised and appreciated.

During troubleshooting, he walked me through each step clearly and methodically, making the process easy to follow.

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!

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.

Great For My Second Mobile Line

Setting up via electronic SIMM was a breeze. Low monthly rate a definite plus. I haven't experience any loss of signal in my travels.

Colleen Vaughn

Site is convenient and easy to use.

I like that I can complete setting up service on line. The site is well designed and easy to use. I was confused on purchasing a sim card. Initially it seemed that I was only offered an electronic card. It was not until after I completed the plan purchase that I saw an option for purchasing a physical card. Perhaps I missed something. Otherwise the experience was very positive.

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!

Quick and Hassle-Free Number Change!

I needed to change my phone number because the one I was assigned turned out to be a recycled number. I submitted a support ticket, and Tello handled it right away — no questions asked, no hassle at all. The whole process was completed within just one day. Really impressed by how fast and efficient their customer service is. Great experience overall!

Flexible plans

I like that you can choose exactly what you want to include in your service. This means that for someone like me who rarely uses the phone, you can have a basic plan for $10 or less a month. I also appreciate that you can change your plan at any time.

Tello Customer Service while in Panama as an American

I purchased Tello based on my research for my extended international travel. I want to keep my USA number. I purchased the USA plan and the pay as you go. I am very pleased with its functionality and have suggested my grown children consider switching to Tello. Something went wrong with my Tello service while in Panama. I sent an email to Tello customer service. In less than 24 hours I received a very detailed response. I followed it and my Tello service was restored. I am very happy with Tello and it's customer service!

Contacted Tello support for a port out issue I had with their site. I was able to speak with a knowledgeable tech (Mauricio) who proceeded to troubleshoot the problem. The problem was on my end and he got to the possible solution quickly. Even though I was leaving Tello, the support provided was excellent with one phone call. Excellent company to deal with and with a live human support staff.

A reliable trustworthy business

Thank you so much for being a reliable, trustworthy business. I opted to buy our new phone from you as opposed to Best Buy, Walmart, EBay, and newer tech businesses (that I never heard of before). And thank you for shipping our new phone so quickly. This is our 4th cell/flip from you in 5 years. We appreciate the way you do business: straightforward, no gimmicks, no annoying sales emails ad nauseum, option to cancel/change plans anytime. God bless you all! Oh, and reasonable prices and kind personable (real person!) customer service.

Lucas was incredibly patient AND illustrative! At 77 years old and not very computer savvy, he was more helpful than ANYONE ANYWHERE has ever been over the phone! He never rushed me, but invariably took his time with me to explain things, frequently more than once! I HOPE that TELLO knows how valuable he is not just to TELLO’s customers, but to TELLO as well! I have never had assistance over the phone be this good and I pray that TELLO never replaces him with an Artificial Intelligence robot. He is SO GOOD that I would be willing to pay what I have paid T-Mobile for 25 years just to use TELLO with LUCAS on staff! Pax Vobiscum, Neil A. Ott of AllmakeApplianceRepair, Inc.

Lucas gave a great first impression of Tello

I just had an excellent first experience with Tello, thanks to the customer rep who answered, Lucas Rodriguez. There were several things I wanted to know - the steps required to get signed up with Tello seamlessly, how long porting in my number would take, making sure Tello supports getting 2FA codes from overseas, things like that - and Lucas answered each of my questions in turn, professionally and patiently. After explaining that to get the Tello eSIM onto my phone we would have to end the call, he made sure to explain the rest of the sign-up process to me. And it was just as he said. Exceptional service! I would be happy to get Lucas again whenever I need to call Tello for support.

I recommend tello to anyone looking for a hassle free mobile service, they offer everything one may need!
