Why customers love us:

I've never had dropped call no matter where I am service is reliable

I have said many times before, I am 86 years old, but still drive and get around, so I only use my cell phone for emergencies. I could not afford phone charges with anyone else as I am on Social Security, but you make me feel safe..Thank you for all the old people who can afford you. Thank you so much for not being greedy.

Fair prices. No deception. GBs that do not expire as long as you renew on time — or early. My kind of five stars.

For a relatively unknown company their service is great. I never have issues. Their payment processing and billing is excellent. Best value if you are looking to save on your cell service by not paying for the big name brand companies everyone knows. My Tello does use one of the top tier brand name networks so you can't go wrong!

So far I've had Tello service. I've had no issues. I've called customer service before just on small issues and they've always answered and taken care of my issue. It's a No frills service but you get what you pay for and I make and receive calls with No problems and use Data with no problem either. At the amount I save for a bigger provider, I save money and get good service.

Tello provides a very good service. It's very easy to cancel/change the plan. I don't have any issue so far.

Great coverage for the cost. And with automatic payments from the bank it's just like having a plan but it's still a pay-per-month system. Don't think it's worth trying to compare remote coverage these days, but we've had good signal when high enough for line-of-sight.

I have used Tello for several years now. It's a cheaper option than the major providers and works perfectly no matter where I go.

great service

Good service for the price. I’ve been using Tello for several months now and they seem to be a very above-board company. I generally only have two bars of signal, but I only pay $10 a month, so I can’t complain.

The price and great service

Tello has always given us reliable service. We are an elderly couple and don't use cell phones that much, so their lowest cost plan is just right. I very much appreciate that Tello has not bumped up the price like so many carriers do, in fact over the past years they have increased the gigs we get at the same low price. We hope to always have them! Thanks, Tello!

The price was cheap, so it was good to use and the speed was fast. And when I posted an inquiry, I got a reply right away, so I was able to solve it easily.

Very solid option for cheap USA esim for foreigners

One of the best network providers I ever worked with

They were very nice to talk to & very informative. Thank You

Mr. Lucas is a nice and calm person. Thanks so much Mr. Lucas

Very good service, and I used to have Verizon unlimited at $149 or so a month. Current customer service is fast and gets me going pretty quickly when I have changed phones. I have zero complaints. Highly recommend them!

These people always are the best. Helpful, courteous ,knowledgeable and friendly regardless of how stupid the question may be

Perfect, clear, easy porcess. Completely satisfied. Best prices.

Nicole was full of patience and friendliness. Nicole made my first Tello Customer Service experience easy and satisfying.

Was looking for a phone plan that was less then I was paying on a big carrier. Found Tello at a great price with a lot of extras. When I had a problem with not being able to send or receive text messages on my old phone they did not try and sell me a different phone as I expected. They seemed to be genuinely concerned and went right to work making changes on their system to allow me to send and receive texts. All in all very happy with this company

I have no problem using Tello as my phone carrier, in state or out of state.

New Sim card delivery was outstanding. Best customer service and best data packe and coverage.

Great service, great customer service and VERY reasonable rates. Best I could find. Highly recommended! A+

Great service and prices you can afford. Easy to do business with. What else is there !!. :)

Have not had any problems with service. Price has not increased for my service

Unbeatable service. Fantastic pricing.

Great prices and the service never fails.

I have no complaints about the service. Automatic low monthly and pay for additional usage is great.

Tello has been a fantastic service!

Needed support and they did great. Thanks

WONDERFUL! Customer Service: Excellent Plan Updates: Excellent THE PRICE IS RIGHT & I don't know why anyone would want to be with any other company!

Tello provide a wonderful cellular service and has a superb website, although there is one shortcoming that should be addressed by the company. For those customers that wish to change their plan they must wait until the day before the plan expires so they don’t lose prepaid value ($$). It would be much better if the website provided a feature that allowed the user to change the plan at any time but have the option of making the change effective on the next monthly renewal date. Other MVNO’s have that feature in their website customer interface. For Tello to continue to lead the industry it would be wise to add that feature as well. Tello please share this recommendation with your leadership. Thanks in advance for considering my feedback.

The best feature of Tello, apart from unlimited call and text, is that you can use it without additional charge anywhere outside USA where a wi-fi connection is available.

The service is very good and the price is amazing!! Thank you, Tello!

This is a great phone service. Inexpensive and I have never had any issues. I even ported numbers twice with no problem.

Consistent, reliable, affordable.

Great network coverage

Easy to switch my phone to tello with esim. Picking a plan was easy and clear. No hidden fees.

Tello is easy to change to had very little trouble able to do everything online.

I am pleased that I have unlimited texting and calls for such a reasonable price.

love how much money i am saving

Customer service was very good.

Tello continues to be consistent in providing uninterrupted cell phone coverage at one third the cost of previous provider. We are totally satisfied with Tello.

I was returning to Tello service and had difficulty on the web to reconnect my phone. Rossio helped me reset things so I could complete my transaction. She was very Patient and kind and stayed with me to verify that everything was done correctly. I appreciate her help!

For those not addicted to their smartphone, this is the place to go for reliable and affordable service. Prompt responsiveness, a variety of reasonable packages... no need for the big expensive brands!

A young woman named Dani was my customer service rep. She went over and above to help me with repeated phone calls until I had service and a new phone. Dani said she'd call back and she always did! I tried signing with another company before learning of Tello, and a guy said he'd call back and that call never came. That's usually the norm. So far, if Dani's extreme patience and professionalism are any indication, everything I read about Tello's customer service being exemplary, are true.

Great selection of different plans at different rates that fit all budgets.

Easy to use tello website to manage my account !

Tello gave me the help I needed so I could choose the right plan.

Simple, flexible, cost efficient.

problems in the beginning, Tello continued correcting until the problem was resolved

Satisfied with Tello

Lucas has been helpful with my issue. He was so helpful. 5 out 5 service. Thank you so much.

Excellent coverage, great low price customer service great. Anyone who wants a low cost provider which gives you everything you need, which is ⭐️⭐️⭐️⭐️⭐️ , it’s Tello!

Not the usual manipulation & expense of the BIG Box providers.

Very satisfied with the service.

Very knowledgeable, helpful and kind associate

La atención de mi problema fue muy rápido y me brindó solución de forma muy amable. Estoy muy agradecido

Great prices, customer service and coverage.

The customer support was amazing

Tello SIM Review – Affordable Price & Reliable Network in the US I recently used a Tello Mobile SIM during my time in the United States, and I was genuinely impressed with the overall experience. Very affordable pricing: Compared to major carriers like AT&T, Verizon, or T‑Mobile, Tello is significantly cheaper. You can customize your own plan and only pay for what you actually need. It’s perfect for travelers, short‑term business trips, or anyone looking to save money. Stable and reliable network: Since Tello operates on the T‑Mobile network, the 4G/5G coverage is solid. Internet speed is smooth, calls are clear, and I rarely experienced any connection issues. Easy activation: Buying an eSIM and activating it takes just a few minutes. No contracts, no hidden fees. Flexible plans: You can change or adjust your plan anytime with just a few clicks. → Final verdict: If you need a budget‑friendly, flexible, and stable SIM card while staying in the US, Tello is definitely a great choice.

Ive never been happier I like everything in general!

I really like the customizable plans. The cost is very low and the service is very good.

Best prices on cell service, never an an issue for well over 6 years, great customer service

Provides consistent SMS capability to me despite me being away from the US. I did a dumb where I didn't configure WiFi Calling on the website properly and couldn't connect for a while, but once I figured that out, that was all that was required to activate my eSIM while physically away.

Was having trouble activating my eSIM but a quick call to Tello support and Andy and their knowledgeable skill of iPhone devices had me connected to the Tello cellular network and ready to make calls.

I love tellos plan I use it for data for my Ipad and they offer a esim with 50gb of data a month for $25+ tax with equals a little over $26 it is so worth it!!

My phone was broken with my eSim. I was not able to find any resolution on the Help Center so I decided to e-mail Tello for help. Their reply was quick and Alex, the assistance agent, was super helpful and very calm. He helped me getting through step by step and finally fixed my problem. I really appreciated Alex for all the helps.

Lucas Rodriguez persued the problem until he rectified it. He was very thorough and extended patience.

I previously gave this company a1 star rating, however, I have since been in contact with an extremely polite and patient call centre representative named Andy Andy talked me through step by step instructions, which although very involved, eventually resolved all my issues. I use the company frequently for travelling to the US and have always found them to be extremely professional and their call centre staff are first class.

I needed help initiating WI-FI Calling and the rep I got was Dana Nia. Dana was GREAT! She was helpful, easy to understand & patient. You have a great employee in Dana! Also, while I appreciate my Tello service & monthly cost, I am really impressed with your 24/7 live Customer Support! While your pricing was attractive, getting ready answers to my questions is what made me choose Tello in the first place

Inexpensive, simple and reliable renewal process, good service.

Tello is an excellent carrier, I like how flexible their packages are, Am generally impressed.

I have had Tello for years with no problems ever.

I was trying to activate my new flip phone. Lucas from Bolivia was patient and knowledgeable. We got it done quickly.

Lucus was professional, and friendly. Helped me resolve my issue quickly and efficiently!

Tello.com has always been easy to navigate and complete the task I set out to do. The service is great and the cost just can't be beat!

Amazing, knowledgeable, and professional customer service experience!! Johyse helped me fix my phone service while being abroad! Thanks a lot

Price is much cheaper than Tracphone . Plans are more flexible as well. Signal is much better than Tracfone, gone from 1 bar to 4 on the same phone. 5 on a newer phone. Customer service is better too. I would never go back. I had Tracfone over 20 years. It went from not very good to useless, and from cheap to not so much. I have had Tello quite a while now, maybe a couple of years now, never disappointed

Tello is the best, most versatile service, good signal, and a most customer focused website and responsive customer service team… Tello =s High Value for their customers💯

Jhonatan Cadima was a freaking hero give that man a raise! I was stuck and freaking out of course because well, you know. My phone is my life as its for personal use...and my business. He came through and fixed the issue immediately! Thank you X 100000000000!!!!!!!

A low cost alternative for the same high cost services with the ability to pick all your plan settings online yourself and apply them instantly.

Easy to solve the issue on time

Price is great.

I wanted to use a different credit card for payment on my account. And the written information was a bit confusing. So I called Tello to speak to a representative to get clarification. I only waited two minutes if that, to talk to a representative, and she not only clarified the process, but verified seeing the new credit card information on her end. I was thrilled that it could be solved so quickly! Thank you, Tello!

Good reliable service at an awesome price.

I’ve had no issues to date and I’ve been using Tello for about 3 years now. Affordable, easy to set up, and just what I was looking for. It’s also easy and hassle-free to change or cancel your plan at any time, which I appreciate.

Life changing upgrade from the miserable legacy carries. They ride the rails of other networks, but provide a highly useful and functional UI beyond anything from the dark pattern nightmare that are all legacy carriers

You guys are good

Very affordable plans, easy to use mobile app,

Initially I had some teething problems getting connected but that was due to my location and not Tello. A supervisor named Stella was fantastic. She listened to my issues, she understood exactly what was required and helped me resolve it. Her communication, problem solving and customer service skills were excellent. I hope she was recognised as a valuable member of the company.

Trouble-free service

The price, the refurbished phone at such a decent price, the customer-response and care received when a problem arrived... I've never ever regretted my decision to quit my long past association with the huge provider and go with Tello! Tello is Stellar! <3

Easily ported in ATT landline number to my Tello mobile device. Completed in 2 days. Keeping the phone number with huge savings.

Great service great prices

service is better than the big carriers and the price is fantastic. The only added costs are fro data when I travel.

Rossio was wonderful! They handled my predicament and helped me upgrade my plan instantly! I don’t know when my home wifi will be restored. But, until then, I know I’m covered. I also learned how to run my tv roku from my phone’s plan… Yay!
