Why customers love us:

I like Tello, it is very flexible!

I used tello services for my back up spare phone that I keep in my car. The price is very affordable for my needs and I use it to call a few friends in Europe. Thanks for a low cost service.

Response within the hour via email. After a period of time, I was asked to call to address the issue. Resolved 100% to my satisfaction.

Idiot proof.

So far, TELLO has delivered the goods: a phone line at a reasonable cost. (as I write this, I am also still waiting for my old phone number to be ported from my previous carrier, but this is not TELLO's fault. I am very sure my previous carrier's greed is causing the problem.) The one thing I do not like with the switch I made (i.e going from my Big Carrier to TELLO) is the transition and its steps (getting the new SIM card, slipping it in the old iPhone, activating it, setting every button in the APPLE "settings" on right, and getting the phone to work correctly between rings numbers and voice mail) is never as easy as one would hope. I am sure this would be equally infuriating with the big carriers (such as VERIZON or ExFINITY or AT&T) but TELLO has no stores and no active phone support, really. Even if they email you back fairly fast after you emailed your question, they always seem to be sending you rote replies of a general nature and rarely apply themselves to addressing the particularities of your case or your question. This means I am spending a lot of time right now trying to figure out how to record a clear outgoing message, and have it delivered to my callers in as few rings as possible. Someone more adept than I am at that game might figure out the hoops quickly, but I feel a bit let down for lack of help, although I cannot deny the technology is amazing and very affordable.

What a breeze to work with polite and knowledgeable CSM team that listen and answer questions without being rude or arrogant. No forever hold and speedy resolution. Thanks for another great experience! Setting the standard.

I have used several cell phone companies over the years and some were ok some were not but Tello is awsome they meet all my needs for a great price and have bigger plans if needed and the 1 time I had a problem they fixed it with in 10 minutes I would tell anyone to give tello a chance you won't regret it

I don't trust my number with any other service. Easy to port into, out of, and flexible plan options make it unique but also easy to use. Option to rollover minutes and data are plus. Thank you Tello for the great service and peace of mind!

Excellent collection of affordable options for flawless mobile service. Very good spam filtering, too!

Does everything I want a phone service to do without any problems.

Extremely reliable

do a great job thank you

I have used Tello for several years now for my cell phone service and it's been great! Never have any problems with making or receiving calls. It is so cost-effective and I highly recommend it to everyone!!

Great price and excellent service almost everywhere and I like out in the sticks.

The actual service is great, but the NUU phone I purchased from you is not so great, which is the only reason I did not give you 5 stars. Once I can afford a new phone the 5th star will magically appear. I will continue to use the Tello service because it is just the service I need.

Very fast and on point! Sebastian Coca was the representative that I spoke to. Thank you!

Works perfectly everywhere, every time.

The price is the main reason for my rating. I don't often use my phone but when I do, the service has always been available.

I have been using Tello for many months and have found it fairly impressive compared to other services. The voice and data work well. However, the cost for international and roaming services is higher than that of most other service providers. It is suggested that you revisit these rates to see if you can lower the cost. This should give you an advantage over your competitors and expand your customer base well beyond the others. Your market share could explode! Food for thought!

I have a $7.50 bill every month. If on Wi-Fi at home or work , use that. It’s great service too if not near wi-fi. I have a very small plan and it works great for me for 4 years now. You can always go up in plan very easy if need to if not on safe Wi-Fi

Great service with affordable cost.

Tello immediately fixed my problem, great service, Fabulous price, always recommend them

Tello is amazing!!! I use it for my home WiFi 🤭. It works great! But after the 50GB is used (I rarely use that much) is very very slow….. so slow you can’t hardly do much, overall it’s a great company, easy customer serve reps and transparent billing. Thank you Tello!!!!!!!!!!!!!!!

I have had Tello for several years now. Excellent service. Never are without a good signal. Even in rural areas. Very simple process to port my old number over. Great prices. So glad I got away from Verizon with every month a price increase.

Have had service for three years and have had no issues. Price is great.

Customer support was excellent and very informative!

Honest and inexpensive, that's the secret.

Fantastic experience working with Johyse on a complicated situation syncing my wife account to mine off of an old work email I no longer had. It took awhile but Johyse was very professional and patient as we worked through the security protocols. Thanks for a great experience.

Veronica Mercado She is amazing customer service Top notch!! She assisted me professionally from A to Z solving the processing the payment for my mother’s Tello monthly bill. Please keep Veronica, and highly recommended to offer her management position/training and new market development; she is a real asset of Tello!

Tello Customer Service is impressive. This morning was the second time they've helped me. Andy walked me through step-by-step, very patiently, how I could use my phone in Europe. Very pleasant experience!!

Very good service and signal for the price.

Great rates and even better customer service!

Service works well in a rural area and the low price makes it a no brainer. The reason for 4 starts is that it didn't allow me to open one site using my hotspot - it is a news station that is not mainstream so it blocked it for "Misinformation." That is a big no-no for me, but that is not on Tello - it's on TMobile.

Monthly bill is so reasonable.

If you want to keep a US number while being outside the US, this is the best solution.

Still waiting for a solution after 2 days

The ability to pick my own plan for a very reasonable price.

Simple, straightforward

I had the best experience with support than I've had in a while, they were patient, and kind, they got me all fixed up quick. It took awhile but I thought I could do it myself. I'm not as tech savvy as I thought, if I had just followed the directions from the beginning, I would have done it right, I assumed too much about my device and got it wrong. Your support was key to my succeeding in keeping my phone. Thank you

An honest, reasonably priced, ethical company that provides what it advertises.

Alenjandra Alvarez was excellent in all respects. She is knowledgeable, patient and kind. She helped for almost an hour with a SIM card that just barely fit the tray and then walked me thru activating my phone and choosing a Plan. She is a gem and dserves a raise and/or a promotion for her service which outshines every other customer service rep I have encountered.

Excellent. I'm satisfied with the service

Call answered promptly and the customer service representative responded Dr quickly and efficiently to my needed request.

Awesome wireless company, very reliable

The agent understood my request and gave me the best answers and even improved it while we spoke.

You should know I rarely rate 5 Stars!! That said this is a reasonable good phone service.

I get all the service i need at a very reasonable price.

I appreciate your services and so much more.

Tello is affordable dependable and I get great service

Tello helped me keep my number the switch over was so easy and didn't take long at all. Adding family lines is free and can see them in my account. I am saving so much money on tello by building my own plan that fits me!

Maurce HAS BEEN EXTRAORDINARILY EFFECTIVE IN LESSENING THE TIME IT TOOK TO GET A CLEARANCE THAT WENT RIGHT TO WHRE I WAS COMING FROM: SUCCESS!!!!!!!!!!!!!IBTOLD MAURICE THAT HE DID IN 6 MINUTES WHAT IT TOOL ANOTHER PERSON OVER AN HOIR TO ADMIT ME BACK INTO TELLIT.

The site is well organized and filled with useful information.

good service

Great plans/prices. Amazing customer support! Excellent coverage.

During the transfer, I had talked to several Tello agents and they were very polite, patient and very professional. This was in sharp contrast to many other companies whose agents are not only rude but also unprofessional.

I keep this as a 2nd phone. It's excellent service and the price is great!

Just simply a good reliable telephone company.

Dependable on wifi and reasonable prices

Excellent Tello is fantastic! Switched the whole family 6 months ago and now save $100+/month. Custom plans are perfect, coverage on T-Mobile’s network is excellent, data rolls over, no hidden fees, and support is fast and helpful. Best value in mobile, hands down. Highly recommend!

Tello always good and reliable service at a very reasonable cost,

Wow Factor! Over a few days, Alison Claros, and other fantastic Tello staff worked to track down what I did to confuse myself ( and them a bit). The short story. I bought a sim, installed - it got a number - and at the same time ported ( err, moved) my old number to them. Somehow, I set my ported number up to be an esim - and worse - used my library email. OMG... What did they do? Well, patiently tracked down my convoluted path and got me connected ( ha!) with my number . I was ready to give up, they said we'll help. They did. Yes, wow Factor.

Great service and good price.

My service was automatically renewed and I did not need it it. I called to make sure it was cancelled and my money refunded. It was handled effectively and efficiently. Fernanda who was the service rep was great.

Excellent service

I have been completely happy with your service since I first switched to your company, great job.

excellent customer services

No problems with the plan

Very fast and reliable help and service have had the service for years and plan on keeping it and adding more phones

Great customer service. A representative answers the call.

Tello customer service helped resolve my issues with my SIM card and that problem was bothering me for MONTHS!

We do not use much data search and phone calls, so Tello is what we wanted. If we sometime need more data and phone call time, Tello is flexible to change current plan.

Customer service is truly amazing and helpful. Their prices also are so low that it's hard to believe.

Great coverage, great price 👍🏽

Easy to get started, by far the most inexpensive rates, good coverage everywhere I’ve gone in the US.

One of my calls was answered bby a very helpful person.

For the price the phone does everything I need it to do

I always loved Tello! I only moved to another provider because I was in Alaska on vacation and experienced problems staying in touch with family members.

I have not bad experience with the service and no complain whatsoever.

I'm really happy with Julia She Answered all my questions and help me change my due date as requested. She was quick and provided all the necessary answers and help me log into the mobile app as well. I had no idea that for the mobile app you need a 1-time code instead of the main password use only for the website even though is stated at the bottom. Plus, she did not ask for a Survey I asked her to send the survey because of how many answers she gave me and how patient she was. Additionally, she shows me how to use the chat and tells me is only available when the lines are congested.

Been great. No issue just works perfectly. The biggest for me, is no contract. You can adjust to higher data or stay on the budget you like. I switched from unlimited to a more affordable for me and I'm happ. No stress no hustle. Just adjust to your liking.

Smooth and easy to use great value thanks

Every Tello representative I communicated with via email was exceptionally patient and helpful throughout the account activation and number porting process. I am truly grateful for the outstanding customer service and support.

I like the service of Tello, is friendly and convenience , I don't have worry about surprises in my bill that works for me. Thanks

I rarely use my mobile phone, so I am happy I can have a simple inexpensive plan ($10). It is great to be able to choose exactly what you want.

Luciana was so helpful courteous. I was having a lot of issues with my previous carrier trying to port into Tello. She listened patiently, reached out to higher level management. She really went above and beyond to make sure she was able to resolve all my concerns (which stemmed from my previous carrier). I was so impressed that I asked her how I can give feedback because she deserves to be recognized. I would recommend Tello because from the smaller companies which offer affordable plans, Tello stands out for customer service.

I appreciate Tello's low monthly price, ease of personalizing my plan online, reliability, and the unexpected perk of increased data without paying extra for it. Thanks Tello!

Tello is easy - straight forward pricing - I have never had an issue with the service, period. Switch now!

Great price and excellent service!

Besides the great prices, have been a customer for some time and not a single problem. Would highly recommend them.

Good service, excellent value!

As a current customer, I feel that the service per dollar spent is exceptional. In this marketplace, the big three are still charging in some cases $40 or more for monthly service with data. TELLO is delivering the SAME phone/data access for a fraction of the price.

I have been happy and content for years since I first begin my service. I have had offers to change and I will gladly Remain with TELLO. Sincerely NM

They tried everything they could on their end and it showed they actually care about their customers, they would reply to my email within 15 minutes or less, and the issue wasn't even on their side, it had to do with the iOS I was running at the time, Tello is awesome and affordable. I recommend them to all my friends and family. Thanks again Tello

Good service. My bill is coming earlier almost every month

Ported a phone over to go from $79/mo to $25/mo. It was easy once I got a porting code from my previous provider.

We love Tello! Never had a problem with our phone service for years now & the price is incredible. We are seniors so every penny counts and we can not afford bad service especially in time of need.

I am generally happy with Tello for my mobile phone service. The price is 5 STARS easily. The coverage is an average 3 STARS. Living in a small city, the coverage is fine. Traveling along the interstate system is fine. But outside of cities and the major travel routes, the coverage is less than desired. Data is 3 STARS. I rarely use my allotted data usage from month to month. But this last month (NOV 2025) while on an extended road trip, I ran out of data with only 1-2 days left before my auto renewal. It would be nice if Tello banked at least some of the unused data from past months.

I was with you once before. Then, the experience was not great- too few gb of data to use. Now, you are on par with other companies in the amount of data available, and my experience with you has noticably improved.

I like your customer service. She was very kind and helped me in detail.

Been using Tello for a few years now. The service is good, easy to use, and it's a great price. It worked well for us during our trip to Scotland, too.
