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

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!

Lucas was the Tello rep who helped me through the process of updating my phone and restoring service. Lucas was patient, professional, good-natured and, just to emphasize the point, patient. I dreaded this process but my fears were unfounded because I got lucky and Lucas happened to be the person who took my call.

Used this for cheapest possible SMS + WiFi Calling service during extended international travel, while hopping between local eSIM providers for data. 5/5, worked perfectly for 10 months. Allowed me to keep my local USA number while traveling.

Loucast had done a phenomenal job , helping me activate my new phone.

I was pleased to receive the customer service required to port my Mint Mobile number to Tello. The representative was friendly and knowledgeable and got it done.

It's inexpensive and uses T-Mobils towers, if you don't need the extras or priority data then this is great.

The TELLO customer support person stuck with me through multiple attempts to activate my new iPhone esim. Finally got things working. Do not confuse this actual TELLO support person with the JustAnswer website that you could accidentally end up at! They were more interested in selling me a subscription to JustAnswer than solving my issues.

Tello is very affordable with different plans. No problem with mobile receptions.

Got Tello Service to plan for an International trip. Got a used DUAL SIM phone to bea able to use TELLO and the local country's phone service ON THE SAME PHONE. TELLO works,BUT YOU have to know-how the settings work. TELLO Customer Service via PHONE was excellent!!! 5- STARS It is VERY HARD to get the direct answers needed by JUST using the online FAQs. I hate FAQs. They don't allow you to ask about something NOT mentioned in FAQ. On phone, representative was SO HELPFUL, PATIENT & kind. Spoke clear ENGLISH AND was articulate. He was great!!! 20-STARS!!!!!!!!!! I just did my PAY2GO & activated International Roaming as the rep suggested. Will test the feature later today. Thanks TELLO

Great service and value - love it.

It works very well, I haven't had any problems and I managed to reduce my cell phone bill by more than $100, and it works well in other countries too. I believe I made an excellent choice.

I switched from TracFone at the suggestion of my 22-year-old about 3 years ago, and I'm paying around $100 per year with much better service!

What a customer pro model...I loved it . I ported to new number within 5 min Awesome service

I have been using Tello for 7 years and am very pleased with their affordability, service and flexibility. The process to choose and modify your plan anytime is simple and straight forward; all their plans are very affordable. I found their International Roaming plan very useful and reliable. Definitely recommend them!

Tello is a lot of bang for your buck, great service and coverage at a very low price. Like their website also, easy to use. Highly recommened, 2 thumbs up.

Have had Tello for a few years now and it has been 100% on providing connection and the ease of changing plans online without needing to wait to talk to an operator is gold! Previous provider was soaking me for $200 for the same service Tello provides for $50

Excellent signal service area but you pay less a month. From opening my account to getting my Sim delivered to my home and setting up my phone was just way too easy. I have yet to experience any issue with my service. What I did notice was all the money I was saving monthly. Thank you Tello

My wife switch to TELLO 3 months ago. I did last week. We are very happy and pleased with service! The support is the best. Took them like ten minutes to replace phone # . First # did not work with Telegram App. Second yes. I can say if looking for good service go with TELLO.

Good company in a sea of bad ones.

I use the system for data only via a cell number. Once up and going it has been seamless for several years and the cost is the lowest in the industry.

Affordability

Very happy with your service

Mostly fine service, sometimes internet slow or doesn't work I mostly do email, text, calls, read news, been with tello for a few years and plan to stay with them a few more I think

Tello is the best for my needs. Completely hasslefree. Excellent service. No additional charges. Great flexibility with the plans.
