Lucas was able to help me fix and restore my Tello Phone Service. Thank you very much Lucas for your patience and understanding. Tello: You have an excellent agent. I’m retired now but if I were still in business I would hire him immediately. Thanks Lucas.

Excellent service, very easy to understand and use, excellent price.

Zero connectivity issues, excellent customer service and very responsive, price is by far the cheapest. I love the mobile app very easy interface efficient and stable. I recommend Tello every day. I have been a loyal user with 2 lines for more than 4 years. The unlimited plan started at 20GB, then increased to 35GB and today I got an absolute happy surprise that they increased it to 50GB that's by far more than double than any best offer you can get at this price and I did not even had to ask or complain. Go Tello, you are the best in your rank and I thank you everyday for making my life a little bit better and less stressful compared to other mobile services. Again, strongly recommended.

I was tired of paying big money for poor service, 2 bars at best from both AT&T and Verizon. Tello has given me FAR better reception, full bars all the time here, at a far cheaper price. The ONLY thing I don't like is the limited choice of phones and the poor quality of refurbished phones. Buy new, not used. Word to the wise.

My unlimited plan got upgraded for free to be 50 Gbs of high speed data. I think it used to be 20 Gbs before it got slow. I’ve been a customer for a year or so now. I’m not sure how much this benefits me. They sure presented like an amazing gift so I’m happy for that experience.

I've never had any problems with Tello, NEVER. I asked a question not too long ago & received a response within 24 hrs. Great! No issues!

good quality and affordable

Tello gives me the service I need for a reasonable price. I have never had a problems of any kind with tello.

One of the best phone operators I have ever had, great rates and great coverage everywhere even overseas

Your help me get the phone back on line. Thank you

THE YOUNG LADY THAT HELPED ME WAS JUST AWESOME, PATIENT WITH ME AND SWEET. She had such a beautiful and friendly voice, I could have talked to her longer. THANK YOU FOR YOUR HELP

The best company ever. I now have 3 phones and get great signal.

I've never had any problems with the Tello reception.

We've had great phone service since we switched to Tello. No lost calls. The price is very affordable.

Flawless cell service for my 3 years. I use automatic bill pay and I have saved a small fortune. Keep up the good work !!

1. Price is right. 2. They don't consistently bother me with unneeded {but surely marvelous!} added stuff. 3. Service to date has been perfect.

I've found that the greatest Tello attribute is consistency I have had no issues with this company from Day One. I think my phone Plan is a Great Value when compared to other National carriers.

never any problems

Absolutely great customer service. He was willing to help to reduce cost and also gave me the solution.

Good price, good service!

As far as we're concerned switching to TELLO was the best move we ever made regarding the low cost, high dependability communication service. I still don't understand why some still choose to pay a much higher monthly price for locked in plans that offer very little in return.

good phone service, website very easy to navigate

It's basically ok phone company, just as good as the others.

It was a great one and everything went smooth and better than what I expected m, it was the middle of the night when I had an issue with my service and the customer service Mr. Maurice Perez was very helpful and showed great patience as I had a very important call to do in regards to my work.

I've been using Tello for a couple of years and it has performed very well. It is on my wife's Moto 5G phone and there is no gaming or other intensive use.

I never have to think about tello. It works, it's easy, no contract.

Thanks for helping me with change the number, I appreciate it!

Very helpful customer service, explained and walked me through changing SIMs succesfully.

Really good like prices easy to get in or change plans and they have a lot fo service everywhere

Excellent Service

Fantastic rates; I can't understand why more people don't use them and why you don't see them reviewed in places like Consumer Reports. And their support is superb – quick responses and actually helpful answers.

The representative was extremely knowledgeable and helped resolve our SIM transfer will we were in the Apple Store

Great service! We've had others in the past, with them the price goes up and quality goes down, but not with tello.

The service is solid and seems affordable but doesn’t offer enough data. Extra data is pricey. If you’re in a remote area, the reception is not great. I have one to two bars in the house. I live in the Mojave desert.

loading their esim and porting your # is a breeze! Their pricing can't be beaten as well! And you call their customer service and you get a person..no phone tree!!!

I do not use the phone much, but each time I do the contact to the phone system works just fine!!

Excellent price for seniors

Happy with their service and happy with their price!

low cost, custom plans, very good customer service.

Excellent service, excellent coverage.

Price coverage

It is convenient to use, the charges are reasonable, and the customer service responses are professional and prompt.

Great experience , I live partly in South America and when I’m in the US I just up the unlimited and use the phone for work and everything , but when in south America. I turn it all down and it cost only $8 to keep the phone and still use it on all WiFi calling .

It is easy to get the roaming resources abroad, and I can have my own cellphone number, I could start to use it when I was in the US. Once I landed in Calgary, I could turn on the roaming and had the Internet immediately, so the experience was so nice, I would like to keep using tello company.

I’m just happy to switch from my previous cell phone provider. My son helps me out with the process. I’m happy with the great customer service experience. Thank you!!!

Sebastian was extremely knowledgable and amazingly patient and kind with me as we changed and e-sim to a new phone and helping me change the sim card to an old phone.

Dependable service with a great price. Even international calling is included and working, a big plus.

Easy to set up, easy to manage. Great pricing and package

The most affordable plan in the US. Signal down occasionally in some blind spots but generally usable.

The best deal. Cell service works great.

Excellent customer service. Relies quickly to emails. Human beings are always available to help.

Tello is the best

Easy to use, to manage and to get support. Good price as well.

I travel abroad frequently so it’s great having Tello to make calls to the USA, but even more importantly, to receive verification messages. When I return to the US, I use to renew my AT&T subscription but that was getting difficult and expensive so I switched to eSIMs. I just discovered that I can easily change my Tello plan whenever I return. Tello is far superior to the eSIMs and AT&T.

How easy it was to upgrade to a better plan, not allowing a salesman to bombard me with useless plans, my choice my plans, after initial test drive common sesnse dictated to upgrade to better plans. Thanks

We switch to Tello over a year ago when we moved from the us overseas. For such a low price per month I can get sms messages from banks and my grandma can call my US number. In that time they also cut pay as you go rates so they are now competitive with data only eSIMs but often with better service. The service in the US is deprioritized compared to other major networks and especially noticeable outside cities but it still works and is a good option for the price conscious or travelers. There’s no catch and customer service was great the one time I did need help. The only thing I don’t like is that there isn’t rollover if you switch your custom plan. So for example my monthly plan was ending with 2G of data left and I wanted to switch back to my usual overseas plan without data and there wasn’t rollover. If it wasn’t a difference of less than $10 this might matter more but because of the price it’s more something to be aware of.

Fast and reliable service at an economical price.

Tello's recent activities precisely meet my needs.

Great customer experience from two separate agents

I spoke with two reps, Sebastian and Andy, and both were knowledgeable, professional, and efficient. I needed to move my eSim back to my old phone but could not through the self service. Sebastian generated a new eSim for me and gave me clear instructions on how to proceed before we disconnected the call. Unfortunately, I didn't follow the instructions (ROFL) and to make a long story short, I ended up deleting ALL the sims on my phone including the new request. I called back and spoke to Andy, and she regenerated the eSim again for me and cleaned up my mess. Now I have the eSim working on the correct phone. I have been with Tello for years now, and it's just solid phone service for a good price and 24/7 customer support that can't be beat. Worth every penny.

Low cost efficient service.

My whole family uses Tello because they have different plans that meet all of our needs. I recently ordered a different sim card so that I could have an extra line for a trip. It got lost in the mail so I contacted Tello customer service to cancel that line. They did so immediately and refunded my money with no issue. Never had service like that from other service providers before. I highly recommend Tello.

Tello has best affordable plans

Excellent price and service. Love it.

The knowledge and amount of time and patience from the service representative was sincerely exceptional. A great company to deal with.

Very Happy with Tello! This is October the 4th 2025. I am with Tello already for several years, and I never had any problems with them. Whenever I had a question, they answered me right away. Their prices are VERY reasonable! I am recommending Tello to all of my friends.

Generally good coverage that is consistent in our area.

Exelente atencion y rapida resolucion de los asuntos planteados.Muy buen trato profesional.

I could not believe the value of Tello but my ai recommended it so I thought I’d try. It was exactly as advertised. But what put it over the top was customer service. I called to change plans and was connected with an actual person who was knowledgeable and helpful. Where does that happen anymore? Solution found and very happy.

Love my Tello service ! Easy to navigate the site 🙂

Everything is great from the moment you go to the web site. Great prices for great plans.

Excellent, quick, easy customer service. 10 out of 10 experience. I've been a Tello customer for years, and never needed customer service help until a couple of days ago. I am thrilled to report that their customer service team is equally fantastic as their phone service and prices. Highly recommend.

Very Helpful in transitioning from one iPhone to another iPhone with the same number!!

you offer low cost plans where the customer doesn't have to pay for more service than they need and the website is easy to use

I've been using Tello for many years now, and I've always found the service / coverage to be as good or better than any others I've used. The best thing, however, is how easy everything is to do online. You don't have to call an agent to get port out details, for example, which is a breath of fresh air. Try that some places and you're on the phone with a foreign call center for 15 minutes.

I found Tello phone service is great quality at amazing price that is hard to match also their customer service is very good and friendly. I will always recommend to everyone. Keep up the great service!

A courteous and professional human being walked me through ( and resolved ) my issue ... thank you for your customer consideration

low cost and good service

Nothing but good things to say about Tello. Reliable, cost-effective, professional.

Wonderful app that has really helped our business to grow

I’ve been using Tello now for about 6 months and it’s been smooth sailing so far. Sometimes there seems to not be cellular data, when web pages and apps stalls, but could be the location gets a weak signal. Calling Cust Service is easy, quickly responded with support in a caring and professional way. Let’s not forget the great prices in the building of your own personal plan accordingly to individual needs.

This service is absolutely fantastic! We used to be with T-Mobile for years, but we switched over to Tello for a better price, and the signal quality is just as good as T-Mobile's. We’ve enjoyed over a year and a half of flawless service, even adding an extra line! I wholeheartedly recommend Tello—it's been a game-changer for us!

I had to change the review. Tello has the best customer service and I am keeping 1 line of service with them because of this. I had to go to a competitor because they offered me a better phone with the more data and unlimited talk and text. I really like Tello though. Thank you

Very good services

There's nothing cheaper plan wise. Your website is nice, clean and simple to navigate. Customer service is spot on and speedy.

The operator was very knowledgeable and pleasant.

Love Tello! Excellent service & I am kept informed each month that my service will continue. Also a great price.

Economical and reliable

Good Deal, Adequate coverage area

Customer service agent was extremely helpful and patient through the process of getting my phone and messaging back in service. His knowledge made the process easy.

Good Service Been with Tello for 7 years and have been happy with them ever since. Planning on staying with them.

Very reliable and a fair price.

low price, easy upgrade to better phone, ease of doing business

It just works.

Love, love, love Tello!!! Great phone service. Great price. Clear reception. And had to call Customer Service to set up a different phone and she was so kind and informative. Thank you Tello

My family has been using Tello for a few years now. Tello provides a great service with great price with no hidden fees or surprises. I also love the free international call service as my dad who doesn’t always have his smart phone on lives overseas, and I can call his land line anytime. The customer service has been great, being able to talk to a real person if you need to. While the price of many things are going up, I can’t believe that Tello’s service got even better (more data for the same price) a while ago! I love Tello and I hope the company stays in business for a long time!
