Since 2013, I’ve been researching, reviewing, and writing about the wireless industry through BestMVNO with a focus on MVNOs.
In this guide, I will explain everything you need to know about Tello before you subscribe. I’ll review each of their phone plans with you, and go over any gotchas that they might have. I want you to learn the ins and outs of Tello so that you can make an informed decision on if this is the best place for you to spend your money.

How Tello Plans Work
Tello Mobile soft launched in the USA in late 2015, and formerly activated customers on the Sprint network. On 1/18/21, Tello began activating all new customers on the T-Mobile network.
Although the MVNO launched in 2015, its parent company, KeepCalling, is a global telecommunications company that first registered in the USA in the year 2002. From 2011-2014 KeepCalling grew its revenue by over 20000% and was named by Inc 5000 to be one of the fastest growing companies in the USA for 5 consecutive years. With Tello, subscribers join a company that has years of experience in the telecommunications market.
How Tello Phone Plans Work
Tello allows its subscribers to custom build their own cell phone plans. When you custom build your own phone plan with Tello, you’ll enjoy having no contract, free tethering, and international calling at no extra charge. However, the highest data containing plan with 35GB of data is the only one to offer unlimited data at slow speeds of 256Kbps once the high-speed data allotment runs out. Prior to December 2023, all Tello plans with data contained unlimited data at 64Kbps once the plan’s high-speed data allotment was consumed. Tello decided to lower its prices and increase the amount of data included with some plans in December 2023 instead of continuing to offer slow data speeds after the data allotments run out. Customers that wish to have more data can purchase pay go credits or renew their plans early. Customers that renew their plans early and don’t use autopay billing do get to rollover any unused data that they have in their accounts.
In May of 2021, Tello updated its international calling list to include more than 60 countries up from just China, Canada, Mexico, and Romania. Tello charges state and county sales tax, and for the federal universal service fund.
Supported Phones And BYOD Devices
Tello does sell mobile phones, however, those that already have a phone are welcome to bring it to Tello, as long as it is out of contract and compatible with the T-Mobile network. Phones must also support VoLTE HD voice calling. Most universally unlocked phones from Motorola and Samsung are also compatible.
Where To Buy Service Plans And SIM Cards
SIM cards and plans can be purchased directly from Tello and through Amazon.

How To Port Out Of Tello
Porting out requires you to call Tello to get your account number. You will need to submit to them your name and email address. They will also ask you for your new provider name. Tello does not use PINS or passwords and so your port out password defaults to 0000.
Phone Unlock Policy
Tello sells all of its phones unlocked, so there is no device unlock policy to worry about.
With the unfortunate shutdown of our previous provider Boss Wireless looming ahead, I used this website to find our next phone provider. Tello came in at the top for us, as everyone gets the same low plan prices and everyone gets their own plan, no matter how many lines we want to manage under one account or how many individual family members want to manage their own accounts. Better for us is that they offer the monthly prices we would have to pay other MVNO’s for 6 months to a year up front to get, but we only pay Tello monthly. Some may see this as not getting a multi-line or multi-month discount, but what Tello really does here is not penalize individuals, low-income families who are not able to afford annual bills or anyone who does not want to take the chance that their chosen phone service provider will slam its flip phone shut 5 months after they made an up-front payment for a year. Yeah, I’m looking at you, Mint Mobile, who made this annual pricing popular by use of a celebrity spokesperson, but just got purchased by T-Mobile, still shows annual pricing on its website that excludes all additional fees they add on at the end of the bill, and now includes a large degree of uncertainty about its future, even 6 months from now. Also, although Tello doesn’t include every tax and fee in the price, they are really easy on the wallet when it comes to adding tax at the end. Real intelligible English speaking human customer service that is available 24/7 also helps. I did need to talk to them a few times, mostly with questions, but also once to fix an issue with wifi calling that was discovered to be an oversight on my part, something I forgot to set in our dashboard. Every time I spoke with someone, I heard a human voice that I could understand very well, even though one or two I could tell spoke English as their second language. I mean to say that although English is not everyone’s first language, Tello’s support, at least everyone I spoke with, speaks and understands it fluently and is not just reading a script. They also are courteous and knowledgeable of their products and services, which is also lacking in many customer service call centers these days. Most of my experiences with their customer service came from calls I made on a Sunday evening, as late as 10:30 at night, not to mention the call I had to make at near 11 o’clock on a Tuesday night, and in every case, I found their humans to be very courteous and helpful. I did see a complaint somewhere where someone didn’t like having to create an account to get the total price of their phone service plan. This was my first customer service call actually, on a Sunday evening. The agent I spoke with, again very courteous and knowledgeable, calculated my tax rate with just a zip code and told me to the penny the total price of the two rate plans we were interested in right over the phone. We were not surprised when we did get our account and activate our lines, thanks to humans who understand and actually do seem to care.
Having been with Tello only for a few days, I really can’t say too much about long-term stability and reliability. That said, because our previous provider is to shut down and one of our lines was coming due, we had to purchase our Sim kits on Amazon, which got them to us much faster than having them sent through the mail, even faster than the $5 priority mail Tello offers on the website. Our SIMs did come as a 3-in-one pop-out style that seems to be the common way of selling them these days. We were able to activate them with little trouble, although there is a bug in their human verification system that allows selecting images on the computer where I started the process, but won’t let me hear the audio version that works with my screen reader, choosing instead to show me an error message indicating that my computer is sending automated queries to their servers. This was one of those times when I needed their human customer service, which although they could not solve my problem over the phone, told me to try it on a cell phone, which worked perfectly on the same wi-fi network. Once I got past that bug though, activation was very smooth, and the porting of our numbers went even faster than expected, taking nearly 1 minute each time. Except for the early wi-fi calling issue, our service has been flawless for the first 3 days, and I’m not expecting any trouble, since they use T-Mobile’s network, which has always struck the best overall balance between reliability and device compatibility in our area.
The only improvement I want to see now is the inclusion of all the taxes and fees in the advertised price. Here where we live, the taxes they do add on are less than a dollar, but still, I prefer to see it up front rather than having to call customer service or set up an account and enter in all my billing info and calculate an extra charge after seeing the plan price. Our previous provider seems to have been a trend setter in this regard, as I have seen I believe two to three other MVNO’s do it in the past year. Still, when it comes to the total price, Tello actually beat out everyone for what we needed, a no-nonsense plan that includes bells and whistles and all the data we need, and no penalty because we don’t have a large number of lines managed under the same account and want to pay monthly, and even with the added taxes and fees, they managed to cut our bill nearly in half. As I said, I can’t comment about anything long-term, but we do seem to be getting service that is on par with other providers we have tried, only at a much lower price, and the customer service is nearly unbeatable. Now just fix the advertised plan pricing so that it includes everything on the front page, $14 should mean $14 charged to the card on file, or just make the advertised price $15, and we’ll all be happy as clams as they say.
Final thought, please update this article to mention that Tello sells their SIM kits through Amazon, not just through their website, confirmed through customer service and by our purchases, and that we need a Tello SIM kit, not Sprint, which has been officially dead for some time now.
Tello is my main phone. Been with them for over a year.
Speeds on Band 41 at my house are much faster than any of
the other networks. 70-120 mbps, Tmobile and ATT are about 4-16 mbps,
Verizon less than 1 mbps.
Will stay on Sprint as long as I can, hoping that the B41 tower stays
on LTE and is not converted to 5G. It is about 7 miles away, the other
network towers are about 2 to 5 miles away.
One of the best and unique things about Tello is that you can rollover your
minutes and data if you renew a day or two early.
Prices are excellent also.
