Why customers love us:

Process for migrating to Tello was super easy. Whole process was completed in just a few minutes.

Tello is very popular so I had to hold for a long time and call back a couple times. But once I reached Maurice, my problems were solved. He took all the time I needed and provided clear, complete, reassuring information, above and beyond requirements. Thank you!

Very affordable and flexible plan!

The service is perfect and exactly what I was looking for. It allows me to keep my number virtually via eSIM. They do have their own app that you can use for dialing US numbers, but it definitely needs a lot of improvements.

I use Tello for a secondary mobile line and am very pleased with the service and especially the cost. No issues whatsoever. Their international roaming features are excellent and surprisingly inexpensive. Highly recommended.

Tello is great. Original setup was easy. That's important to me as I am a senior citizen. It just rolls along. No issues with coverage. I only use it for calls and texts, but's is reliable for that.

Was a breeze to set up. Porting of Skype In number worked perfectly. Everything well laid out and organized online. Only once needed to utilize phone support, and that went without a hitch too.

Excellent service!

works all the time, no outages, no technical isues.

Flexibility with data and minutes, being able to change month by month, all at a very reasonable cost

Outstanding Cellular Service Since obtaining Tello service several years ago, I have not had a single issue with my cellular service, not a single issue. I have and still do highly recommend Tello to everyone. And, on top of great service, the low cost is also outstanding.

Have been using Tello for a couple of years now and never had an issue. The choice of plans are ideal for my needs and the monthly renewal is seamless. For me, Tello is a budget friendly full service cell phone service.

Tello has been very reliable for me, from at home and abroad.

Its low cost is highly attractive to me, plus getting free texts and phone calls; also love being able to call free all over the world

Talked to phone service trouble specialist. He guided me thru the issue step by step. Within 10 minutes I had my phone service restored. Outstanding! I highly recommend Tello. You won’t be sorry.

My thanks to Tello and Mauricio of customer service for guiding a tech newbie through activation in April of 2025 and again thru a scary situation - loss of SIM card. Mauricio guided me through how to order the new card in 2025, and in 2026 assured me I am not the only one whose SIM card has gone missing. The support is a gift. I remain appreciative.

I reviewed Tello before and I can only give them 5 stars. Their rates are very competitive and I get good cell phone coverage all around the country given the fact that they use the T-mobil network

I spoke to Julia and she helped me with my problem. Whata sweet woman and very courteous pleasant and knowledgeable. Kudos to you Julia for a job well done. I would give her 10 stars if i could.

I tried many mobile services, but none as reliable and affordable as Tello.

Quick and easy - 1,2,3 Got up and running in literally seconds and got my entire family connected without ever having to talk to an agent. Reliable solid communication for our entire trip, A+++

Tello provides great talk and text service at the best price ANYWHERE! I love my flip phone!

The girl that helped me deserves a bonus for the problem she solved for me! Robert Langdon

Tello is the best in everything.

I lucked out, both times I called Tello and Julia answered. The first time was to answer all my questions about starting a family plan, where she was incredibly knowledgeable and helpful. When i messed up the eSIM activation on one of my lines I called and Julia answered again, and resolved my issue in minutes. Super helpful, and I am super grateful

I was able to get what I needed with Tello in less than an hour and couldn't with At&t in 6 hours. I needed to get rid of voicemail with no message and Tello succeeded! LUIS was awesome and took me through even installing the Sim card

Best deal in América

price and performance

The best part of your customer service is the responsiveness. Verizon is hard to reach and when you do, they are unresponsive; not Tello. I think my trouble activating my phone on Tello was due to a failure in Verizon's cell towers and Tello might have realized that sooner. After a day of trying we succeeded, because Verizon's towers were awake again, I think.

Laura Litardo from support she was really kind with helping me with my issue I will always be grateful for her help.

Reasonable prices help us

It’s great that you provided this service,setup was good just missed a big part about setting up the 911 on app didn’t know about it too receive calling and texting,that was very frustrating,if you can make sure people understand that they must complete this task before they go over seas that would be very important.

Been using Tello for the last couple of years... Love the low price plans . And very easy to use website.

Cheap and reliable phone service

Works well in the US. I use it since years and like that I keep my number

Super easy, no hassles, no snags.

I have been using Tello for many years now. I have never had a problem with their service. When I wanted to join a new phone years ago, it was a Google Pixel 5a5g, a new technology (5g) at the time, it was not an easy task getting the phone on 5g, we had no luck with the supplied SIM, we had to switch to an eSIM and that finally worked. My point here is the technician was patient, and worked with me as we sorted out the problem. Remember this is when 5g first became available. Great customer service, rate flexibility that always guarantees you the lowest cost and 100% reliable service for me. There is nothing else I could ask for from a mobile service provider. This review was not solicited, I felt I owed it to Tello after they have done such a great job for me.

This is absolutely the best phone service available. Highly recommend this company

Tello is the perfect solution for having a US cell phone while living abroad. I have always had reliable service with Tello and recently had a good experience with a helpful "live" customer service rep when I needed to change my number to a new phone. I highly recommend them.

i want to tell you Julia is the best. she was clear, fast and very friendly. best customer service i have had in years. i cant tell you how nice and helpful she was. thank you Julia!

Excellent Customer Service, always friendly and helpful personnel.

It provides a stable service for a good price.

The price,quality of phone and coverage is great. Tello lets users know exactly what's going on. The best company we have ever used!

Todo excelente muy feliz gracias

Fantastic human customer service

Every time that I have called, the representative was very, very pleasant, and patient. I would be the one, who was over excited, with my concern, but they would always listen to me with consideration, and my concerns, were always resolved, when the call ended. And for this reason I was left very satisfied!

Excellent customer service! Transferring an existing line with another company was a piece of cake with the step by step information supplied by Tello.

He was a wonderful help, I definitely needed he service THANK YOU alot

Low price, reliable performance. Been with them almost two years.

Easy interface to pay bill

My payment card was compromised and had to be replaced. Tello gave me time to replace the card without interrupting my service.

have been using Tello for over a year now, and my experience has been excellent. The service and connectivity are very reliable, and I have not faced any major issues. I really like how easy it is to customize my plan based on my needs. The pricing is also very affordable compared to other providers. Overall, Tello offers great value and quality service. I highly recommend it.

Excellent, reliable service at a very reasonable price. On the few occasions when I've had a question, Tello has responded quickly and clearly via email.

Super quick and helpful support

Signed up - set up auto pay = no hassle data/voice/text - easy web access - no pain low cost cell service - did I mention no hassle?

Everything was fine until I found out the hard way that I needed another $20 for Pay as u go, for my 2nd line, even tho I signed up as a family plan, and my wife’s phone refused to connect to International Roaming! It would have been nice to know ahead of time that I needed $40 of Pay-As-U-Go just to have roaming for 2 lines!!….The $5 minimum is a joke and does NOT exist! I did not know this and not happy right now and looking for other options! I did NOT need $20 for a 2nd line!!!

Tello just works and is inexpensive. Just what I need and want.

Excellent service without intrruaption, and fair price with online processing.

I'm so happy I switched my cell phone carrier to Tello, it's literally the best phone service I've had in a long time! Their plans are affordable, ($25 a month for unlimited)! Im not locked into a plan like most carriers. My reception and wifi is always spot on, never missing a beat and the customer service is great too!! If you're looking for a decent cell phone plan that's affordable then I highly suggest Tello. You can always cancel it if you don't like it, but it's definitely worth trying it out for a few months in my opinion.

Ormai è quasi due anni che sono abbonato a Tello. Il servizio funziona egregiamente e il numero di telefono americano funziona ovunque sfruttando il wifi calling

We would like to share our sincere appreciation for Tello. We are Dmytro and Victor, and our experience with Tello has been truly excellent. The service is reliable, flexible, and very convenient, even when used outside the United States. What impressed us the most is the outstanding customer support. The support team works very fast, professionally, and efficiently. Every issue we had was resolved promptly and with genuine care, which is especially important when you are abroad. Thanks to Tello, we feel free and connected anywhere in the world. Whether it’s Wi-Fi calling, app-based services, or account support — everything works smoothly and gives peace of mind no matter where you are located. We highly recommend Tello to anyone who values freedom, reliability, and excellent customer service. Thank you, Tello, for a great service! Sincerely, Dmytro & Victor

You deliver on what you promised.

Talking to Sam was a pleasure as she was very polite, not a AI response, and resolved my issue very promptly.

Great service at an amazing price point. I got the cheapest 6$ plan for 2GB data for international visitors temporary use in the USA and it works great

I love Tello. You guys even put up with me letting my bill lapse, which is great never change.

After finally getting through to a real human, the movement of a phone number to another account was finally accomplished, with the phone working.

The nice thing about tello is that when you need help there's always somebody live there to help you. And they speak English! Otherwise, other services are excellent.

I am a seasoned Tello customer who maintaining 2 phone lines with them. I also bought other communication products from them. Any time there was an issue (which is rare) their excellent customer support team responded quickly and resolved the issue quickly and very satisfactoryly. they acted professionally and with good knowledge and understanding of the problem at hand. I was always completely satisfied with their support!. Deserve AAA+++

I've had Tello for years. It's the cheapest, best deal ever. No problems with connecting and it never drops the call. Love you guys.

I've been a Tello customer for several years now and have been happy from the very beginning. The service is good - is wide spread and easy to access..... and every time I've needed help, a *real person* answers the phone - and works hard to see that the help is given. Prices are wonderful and the service is just the best. Thank you, Tello!

They have a very reliable network (T-Mobile). For the price you can't find a better deal.

reliability

Reliable phone service- have had for many years now!

Great service and support. Everything as advertised, affordable options, highly recommended.

I haven't had any problems at all.

The rep, Maurice Pérez, was fantastic! He walked me through the entire procedure even with the original pSIM and handset gone. He waited until I installed the eSIM and made my first successful test call. I was so impressed that I will be adding additional lines from Tello!

not sure why anyone needs to pay more for t-mo/att/etc.

Belen, she is very knowledgeable and helpful, and ensured that my issue was resolved - finally. Also, Sebastien offered good directives to resolve the myriad of issues, at the 1st time I called-in.

Tello has given more security and coverage to my family and me than any other phone provider.

Best all around for the money.

The most reliable service at the best price. I am writing this review to express my sincere gratitude for the outstanding phone services provided by Tello.com. I am truly impressed with the reliable quality of my calls, messages, and data connectivity. Thank you for my recent order on Tello.com. The service has been consistently excellent, and the ordering process was simple and straightforward. I highly recommend Tello to anyone looking for reliable and affordable phone service.

Their customer service is the best I have ever experienced of online it over the phone ( especially as so many companys nowadays cannot be called or just make you sit in hold and never plan to help to begin with). I have interacted with them over phone and another time by email and they quickly resolved the issues. The price is a good I am doing $25 for unlimited data text and calls, it is probably has more areas that have trouble with service for calls or data than a larger company but is a great budget company, if you have allot of important zoom meetings or very high data use functions to use may not the be best one for you. I also appreciate no contracts just month by month, I have stayed with them for a year or 2 and don't plan on switching any time soon.

Atención inmediata a consultas

Lost my phone abroad and had to get a new one. Encountered somme difficulties setting up the eSIM. Tello support team jumped on the issue quickly with an ensuing long back and forth to troubleshoot the issue where they were always prompt to answer. Their suggestions helped me solve the issue with a now working line. In short, quality and prompt support with professionalism.

I was told that when I returned to the USA for the winter, I could reactivate my SIM card from last year. I tried for 2 hours to get that work without any success. I asked some helper online and they told me to do what I had been trying to do. Finally, I asked for a response from the Help Line. They told me that I cannot reactivate a SIM card that has be deactivated. They were very friendly and indicated they would send a new SIM card in the mail, which I should receive within 3 - 5 business days. I have not received it yet but this is day 4, so I anticipate it will be there tomorrow. Next time I will order an e-SIM card.

The cost is very reasonable and the service has been very good although I do not use my phone for a lot of different functions. I like that the company notifies me before they take my subscription money from my account.

I was having a real issue getting my sim to transfer over to my new phone. I called customer service and once I was able to speak with someone they went above and beyond Toto assist me. Very detailed and helpful with getting my account straightened out and getting the eSIM on my phone. Excellent service!!

I went on your website to update some personal information and was pleasantly surprised to find it so user friendly. It took less than five minutes to navigate, find my incorrect info and fix it.

Customer service

Miss Rossio was quick and too the point but was not rude to rushing me which I greatly appreciate and I hope she gets a raise for her stellar performance!

Flawless service

Great value for its price.

This is by far the best option I found online and i've been a happy customer for the last 2 years.

Been using Tello for about a year now. There's nothing to complain about on this service. It's robust (T-Mobile's network is great where I live), plenty fast, and it's flexible - I can give everyone in my house the data they require, for way less money than the competition; I tell everyone to use it. Tello is that name that when you walk through a store and "that guy" from the mobile counter wants to "save you some money on your mobile phone plan" clams up when you say "I have Tello", and they know they can't beat it.

LOVE IT!! Very easy to get started!

Great Service! And a very smooth experience

I like it very good , easy to use

The price is the lowest anywhere. The service is great. I slow down walking past the cell phone salesmen in Sam's Club, hoping they will try to sell me another service. As soon as they find out I have Tello they end the conversation, knowing they have nothing comparable.

have an older cell phone -works OK with Tello will get a new phone soon have the automatic billing works fine and always correct.

The time talk Tello customer service was poilte,new there job and patience

The agent was extremely helpful in first getting my eSim activated, and then making sure I could still do video chats with FaceTime, which is quite important for me.
