Why customers love us:

Happy with customer service.

They are a really affordable and flexible option for mobile connection in US. And the support team is amazing, I was unnable to make or receive calls in a new location, they resolved the issue sending me some tricky codes specific for my phone that worked like a charm, and over the weekend!

Excellent service, Camila have an extremely Great Customer service, I am happy with Tello and Camila. Thanks Again.

After the 3rd call, Franco was able to resolve my texting issues. He was very patient and supportive.

Stumbled across Tello cuz I was thinking about traveling and Grok AI recommended it. Subsequently thought about switching to another carrier, port number etc., but decided to stay with Tello because they are prompt, proactive and help you out. Best of economical, unlimited phone, text, web data I've found. $25? How you gonna top that?

Mauricio Torrez was very helpful. My wife has handled this sort of thing, phones, internet, etc for more than 10 years and I'm just now taking over and I'm fairly ignorant at it. Mauricio was able to explain to me the differences between different types of plans, and was kind and thoughtful in the process. Great job Mauricio! Many thanks!

Customer service was great and my concerns are being handled.

I am very pleased with the consistent, no frills, ease of payment, no drop calls, and low cost service. I hope more people discover Tello.

Jose was phenomenal, he's truly a blessing. He had patience with me, and assisted me to the best of his ability. Definitely needs to be a manager to train on coming customer service agents. I'm literally blown away how fast he solved my problem of not having no service after switching to tello. He walked me through the entire process. The experience I had with Tello customer service, was just good to see as a first interaction with them.

Joseu , was very helpful and kind. He saw to it that my problem was taken care of in full. This man explained everything, and I appreciate that. I love this company and the support that goes with it. Yes hard to find today!

Tello is without question The Best!

Andy was very helpful with my mistake.

I had the privilege to work with a CSR by the name of Fabio on August 28th 2026 at around 1400 Houston time the man was very patient and very understanding. He took the time to explain my contract with my service and also my equipment limitations because I was using an old Google pixel phone. I have had a stroke and Fabio was kind enough to be patient with me when I had trouble remembering things or the difficulty in pronunciation he did not make me feel uncomfortable at all and I really am grateful for that thank you TELLO and Fabio for a great experience picking up a new cell phone Robert McGuire Houston TX

We had a 3 line service with Tello for many years until they cut off the text ability of my wife's number. I called and they insisted that number or account never existed? Strange; it was paid for automatically every month for many years. So on to another popular provider for 3-4 times the cost. Calls dropped everywhere, even in the home. Called them and was told to seek another service. So-Back to Tello for us, hoping wall will go well as it did for many years before. Tello cost is unbeatable!

Tello staff were extremely professional and helpful I appreciate the honest help and they went above and beyond to help me. Thanks a lot

Today Lucas settled my issue with my account. I attempted to swap devices last night to no avail. This morning I called in and received immaculate service from Lucas who was extremely supportive and calm. He walked me through regaining access to my old phone. And we ascertained the issue was with my newer device still being locked to T Mobile service. I was assured my T Mobile previously that the device was unlocked. 10 stars to Lucas for getting my service back on.

within my means

Customer Service by your Tello Support Team Diana

Tello is the best company I ever joined. Literally wouldn't be in good place with it. Amazing service that outmatches all else

Prompt service and appropriate updates are much appreciated.

Everything: price, service, quality of service, customer relations

Fast shipping of the sims card good service iny area. And very affordable

Reliable and an expensive

Lower rates. Specially for retired seniors that do not use mobile phone much. And allow a minimum monthly rate to rollover unused data and minutes for "Custom Plan".

Laura G. Help me recover my number and I appreciate her help so much she was fast, kind and explained everything. Great! She made the presses feel so smooth and effortless ✨🫶🏻

Fast, easy process at an affordable price. Great connection as well, would highly recommend!

Mirvia made my data insufficiency issue go away with a creative solution and saved my day. Buy from Tello with confidence, they have your back when help is needed. 11 stars to Mirvia's outstanding customer service above and beyond the call of duty.

Great price. Easy to set up and pay online, or automated. Never any problems. Price remains stable. International calls are clear as a bell. As good as any other telephone provider.

The EU promo to have access till September 30 is super generous and have saved me a lot of money! Thank you Tello!

I needed to get a sim and the customer service was stellar and I hope my card does take 5 days

Email reply is prompt. But the phone number gets disrupted frequently before reaching support staff

I only give 5 stars because you won't add more stars. Great service, best prices, good support. I've been very happy with Tello for years and have convinced many friends to also switch to Tello.

If you travel a lot, Tello has really reasonable roaming rates.

Tello has great prices and coverage. I like how you can customize your plan based on your needs. Also has great customer service. Excellent in so many ways!

Excellent service

Excellent prices and much more affordable than Verizon or other mobile phone providers.

Very Low Price

After 30 years with AT&T I had some trepidation about switching. Porting 4 lines was simple. The first one took 15-30 minutes the last one was nearly instant (<1). We noticed the increase in speed immediately. T-mobile (what tello uses) is substantially faster. I’ve never seen 300MBs+ on AT&T, the first speed test on Tello was 1.1GB download. Crazy!! Ultimately we changed because we live in Europe most of the time and a legacy carrier like AT&T didn’t make sense. We will know how it operates better overseas in a week but the USA experience is fantastic

Very professional and detailed support in resolving my concern regarding the switching and activation of an eSIM onto a new device.

I've used this carrier for years. The price & features are fair & the service has been good during all that time.

I love Tello! All of the quality and service of a larger, greedy company without the fleecing of my wallet!

Switching from Tracfone quick and easy. The Tello communications were clear and easy to follow.

I want to give a big thank you to the customer service agent Belen who helped me today at Tello. She was extremely patient and kind, walking me through everything step-by-step on my phone. I’m not the fastest with technology, but she never made me feel rushed and stayed sweet and helpful the whole time. On top of the wonderful customer service, Tello’s plans are a fantastic deal. I have one of their plans and I’m paying very little for great coverage. I highly recommend Tello to anyone looking for an affordable phone plan with people who actually care about helping their customers.

Ulike Mint, I was able to speak with someone who was highly skilled and knowledgable and committed to resolving my problem. I have both Mint and Tello services on different lines and this contrasts so greatly over the terrible customer service being provided by Mint. It seems that after Xfinity acquired MINT, its customer service can no longer be relied upon.

I was having trouble porting my number into my new Tello account. Lucas came to my rescue and was very knowledgeable, understanding and easy to understand, and walked me through the entire process. This interaction with Lucas has given me the confidence that Tello was the right choice for me.

I was having trouble trying to Port my number into my new Tello service by myself. My Tello agent was very knowledgeable, very understanding and explained the steps to me as he walked me through them. This was also a good experience to feel confident that Tello is the right choice for my needs.

I received exceptional service when I called. She was really knowledgeable about how to fix my problem. She was very nice and patient with me while I was following her direction. She was great!!

I only use the phone to call and text and Tello is priced low enough. I don't have to pay for things I don't use. Just stop raising up the price.

I am amazed that Tello's Customer Support can be called all time 24 hours and waiting time to have the call answered is minimal. In my case the person who answered was in Bolivia, seemed very young but extremely knowledgeable and very patient with an 86-year-old, almost deaf fart. My case was resolved in less than 10 minutes, and the phone started to work like new. I am also very happy with the free calls to lots of countries.

They offer affordable phone service and an easy setup. Website is easy to use and gives you enough information to make a solid decision. Plus you can check your devices compatibility right on the site.

Excellent service, Data and minutes Rollover, and the Coverage

Clear instructions, easy and smooth transaction.

Consistent service. I have patchy service in my house but it's consistently patchy. In town is fine. Good price

I had problems with activating my Tello esim and Diana was knowledgeable, patient and helpful with resolving the issue. She was able to resolve the issue very quickly. Great customer service experience!

Fantastic service worldwide.

The service agent was very helpful and solved not only my problem but she also helped my wife who I had convinced to switch to tello. She was having trouble with her eSIM and the agent walked her through the process . Again, her patience and expertise needs to be rewarded.

For what it does, it's a cheap way to get a phone service that doesn't require you to pay $50 or more for the same service.

Excelente servicio

Great !! Amazing

I have been struggling with getting sms to work, i spoke with Camila and she was MAGIC. WOw, how patient she is with customer, always smiling and making life simply easier. Thank you so so much Camila.... truly a pleasure speaking with you. You restored my faith in tello!

Fantastic Customer Service, with a very pleasant and helpful representative. I highly recommend Mauricio T. with his excellent demeanour as with all the Tello Customer Care Representatives. In the 5+ years with Tello, I have always received the very best attention, whenever, I call Tello customer service.

The setup was fast and easy, the prices were fair, I ran into a few issues when activating my line while travelling, but Belen was super helpful and she had me up and running in no time!!! Great customer support is what keeps things moving along, so I feel I made the right choice by signing up with Tello. Case number 19124922

Very good service

Ordered a new SIM card and it came so fast and with easy instructions!

Easy guidelines for setup and porting old phone number.

Excellent service and very useful.

Tello is amazing, that is all. I use Tello as my US number when abroad on a basic plan, and the upgrade it when travelling in the US and now Europe. I love how straightforward the product and services are. I forgot that the internet and commerce could be so easy to use.

Diana help me to resolve my issue , she is so nice with the customer service , more people like her

I’m 80 y/o male. I had to call a few times to know what and how to do. Yes I was on hold: called busy time of day; but each representative was more than patient and kind. I was afraid they had reached their wits in, but I called again. This time Johyse so kindly and politely and patiently helped me through the finishing touches which required going back a few touches because I transferred from another carrier, (who was also understanding after I finally got past AI). It was an ordeal, but I was able todo it from home (with lots of help) so didn’t have to take a number and wait for an hour or more. I already had one phone with Tello and liked the service/reception Good enough to transfer my other phone.

Edit (2 stars before): Tello replied to this really fast and refunded the money for this plan. Thank you for this uncomplicated customer service. The plans are cheap and flexible, which is nice. However, you need a US phone number already to get... a US phone number? That makes no sense. Minutes after getting my number, I was bombed with spam messages, which made me cancel my plan immediately, unfortunately. If I could, I would want my money back...

I've had good luck with Tello for many years and just opened a 3rd line. Great service on the T-Mobile network, many price options for my needs including data only. Buy with confidence.

Sébastien answered all our questions with patience, clarity and care. He assisted untangling our accounts numbers, the difference between online account and the Tello app functionalities, the confusion about our accounts and numbers, creating a required new login along with explaining how porting other phone lines to Tello works. Thank you, fantastic to talk to a human being these days rarer to competent ones like him.

I've been using this service for years. I've never had a problem and the few times I needed customer service because of my own lack of knowledge, they've been kind, helpful, and wonderful. Highly recommended!

Very fair pricing and easy to follow instructions for installation. The porting process was efficient and completed within minutes. All in all a very good initial experience after transferring from ATT as a loyal customer for years.

very good and economical

I had an incredible experience with Tello’s customer service Olivia today. The representative spent over 30 minutes on the line with me, patiently answering every single question and troubleshooting all my issues until everything was 100% resolved. It’s rare to find support that genuinely listens, takes their time, and doesn't rush you off the phone. Truly top-tier, professional service. Tello has earned a loyal customer!

fantastic! the agent working with me, Arwen, was so kind and helpful and made sure i was taken care of all the way through.

A good simple service

Nicole was incredibly helpful and patient throughout my entire conversation with her. I came in with a confusing issue — lost rollover data across two lines — and she took the time to walk me through what happened, clarified the requirements clearly, and worked with me to find a fair solution that worked for my specific situation

Very efficient!

Recurring payments keep service going. Affordable communication.

Tello debited me and canceled my plan and didn't refund me, then also debited me for a plan that I tried renewing and still deactivated the plan for non payment. They're now scammy they used to be a good service. And no single response to my email. Update: one have been refunded I am waiting for the second refund before I remove my review. Update on 21/09/2026: they have been very helpful in resolving the issue and have decided to change the rating.

Good 50 gig, and roll over. Good customer service.thank you.

Excellent service, reliable experience

I got the service as a second number but found it to be every bid as good as my primary, V, and very reasonably priced. I also got it because is was a GSM networked phone and the coverage in my garage was good.

I've been with Tello for several months now and am very happy with my 300 minutes/no data. My flip phone for Tello is my backup phone, and I have another identical phone with another stripped-down plan, another network. I finally feel like I have plans that work well for me. I have not had to use Tello customer service, because all is going well. I found their website easy to use when I was setting up the phone and am impressed with the level of detail you can choose to read (or not). The website is set up like a manual with links that you can look at or bypass if you don't need them. It's nice to read here that CS representatives are helpful. The phone connection is great in my area, so I am happy.

Yes Diana really made my day by taking her time and being not only patient and professional but also understanding my needs. Thank you Diana for a job well done. Much appreciated.

Alejandra got to the bottom of & resolved my issue super quick and helped me understand what I was confused about. She was perfectly pleasant, very helpful. Wanted to let you guys know she's terrific!

It was a seamless process. Even the number porting went faster then expected.

First of all, Kudos to Alexander and Nicole--Thank you!! I was looking for a basic stripped-down plan (ZERO FRILLS-just 300min/No Data) to take over my home VOIP phone service by a major cable provider and came across Tello. I took some time to carefully read over the information on their website, and decided their plans and options were very good and flexible for my needs (and I suspect they will be for many others). The online process was easy and straightforward from the start. Selecting a plan, with a truly inexpensive device like the TCL Flip2 w/sim (4/8/26) to pkg receipt (4/11/26) was efficient and fast. Their responses to my two issues (1. Accidently ordering a sim without a device and 2. Requesting a one-time change for an assigned number because of technical issues) was quick, professional and friendly. Tello quickly responded to my email queries/technical issues. Alexander and Nicole were great during the entire process. You can also get online (via chat) with a representative if they're available. The service uses T-Mobile towers. I tried several times and it works well for me. I chose to not have a data plan because I just using it as a house phone. I still get text messages without any issues. And that considering I decided to just get their cheapest flip phone with 4G! My plan stripped plan also covers 5G networks. Don't know what the other user was referring to when they mentioned" you get what you pay." Ok so the toll-free number might make it a challenge to get a live person, but there's a chat and email you can use, and I think it works pretty well. I'll come back an update if things change.

The price cannot be beat!!

The person that I was talking with was a very good operator efficient fast good with words and overall I felt my experience was super smooth and made me feel a lot better about this service since I've had bad experiences with customer service with other service providers so definitely a 10 out of 10 I appreciate how good the operator was

Nicole answered all my questions promptly. She seemed to know them at the tip of her fingers. She was Patient, polite, courteous and helpful. She is an asset to your company

With the representatives like NICOLE I will remain with tello forever. She was not only very helpful and professional but also very pleasant. Thank you NICOLE for a job well done.

Tello was my hero when I needed an international Internet. It worked very well and their packages was reasonable without big commitment.

Knowledgeable agent was able to solve my issue

Mauricio Torrez was so awesome and patient and fixed my problem!! Amazing service thank you Mauricio

Es muy sencillo buscar y solicitar el equipo que me agradó, solo el tiempo de espera para recibir el paquete si es un poco extenso pero pues no es culpa de ustedes.

Arianne was a great help! She patiently walked me through my issue. She gave exceptional customer service.

I recently had the pleasure of using Tello Mobile, and I must say, it exceeded my expectations! From the moment I engaged with their team, I was impressed by their professionalism and dedication to customer satisfaction.
