Try Tello

When my contract with Sprint came to a close, it became clear to me that I wanted to try something new for a change. However, I realized that my options were quite limited with the 4 main carriers in the US whose ads I've grown used to seeing.


This was when the concept of MVNOs came onto my radar: for those who don't know what an MVNO is, it's an abbreviation for a Mobile Virtual Network Operator.

At its core, an MVNO is a cell phone carrier that doesn't own the entirety of network coverage like the 4 main companies do, but instead purchases small amounts of territory through significantly lower rates. This then allows them to sell it to consumers at whichever price they want, making it a new way to have cell phone service for those who are wary of purchasing from bigger brands.

Because MVNOs are typically much smaller companies with non-comparable advertising budgets to the bigger corporations, their biggest competition is typically with each other. And, since there are over 300 MVNOs currently operating in the US right now, the rates are becoming increasingly more competitive, something that is a great opportunity for consumers who are looking to have significantly cheaper phone bills.

MVNOs allow you to have the same (if not identical) service to that of larger brands without the contractual obligations that typically make your service with more notable companies feel restricted.

The main advantage of MVNOs for people who are on the lookout for a new phone plan is the ability to not overpay for things that you aren't going to use in the first place. This definitely became a huge problem for me as I started to realize I didn't need the unlimited plan I used to have with Sprint. Sure, I use a good amount of data on my Smartphone, but not nearly enough to justify the price that I was paying for Sprint when compared with friends of mine who do use enough data for that to be a bargain.

Ultimately, though, MVNOs come down to flexibility. If you want to stop your plan when leaving the country for a few months, you just don't have to pay until you return. Many of the best phone service providers even let the minutes roll over, ensuring that not only are you paying a fraction of what you used to pay, but the service you're getting is truly flexible.

Tello Mobile Phone Plan Review

This is where Tello comes in—as an MVNO, Tello is a relatively new service (since 2014) that purports itself to be a true change for the world of MVNOs. It is owned by KeepCalling, a telecommunications company from the UK that also has set up shop in the US.

Some of the benefits that Tello uses to distinguish itself from the rest of the MVNO market are: 4G coverage nationwide, flexibility with their plans, free tethering away, and no phone-specific plans.

Right from the get-go, though, it's clear that the service is very intuitive. Tello has their “Build Your Own Plan” widget that lets potential customers design their own plan to see how much it will cost them for a monthly, pay-as-you-go contract.

For those who are more interested in simply signing on with a preexisting plan, Tello also offers a decent variety of “ready-made deals” ranging from $10/month for 500MB data/200 minutes/Unlimited text to $39/month for 10GB data/Unlimited minutes/Unlimited text.

Unlike other MVNOs, Tello unfortunately does not cover necessarily everywhere in the US. However, they do provide a helpful map of their 3G network so you can understand exactly where they are able to reach before you commit to a purchase.

Because I live on the east coast, it was clear that I should at least give Tello a try to see if I like the service. So, that's just what I did.

My Thoughts on Tello

Hands-down the biggest advantage for me of being on Tello is the flexibility. As somebody who doesn't use my Smartphone that much, I was able to pay only $14 per month to have 1GB of data and unlimited texting/calling. This was a huge plus for me, as previously I would frequently think that the amount I was paying for my phone bill didn't feel accurate for how much I was actually using.

I have only been using the service for a month, but even knowing that I'm not locked into a contract puts my mind at ease. For example, if I want to go out of the country for a month or longer, I can simply leave my phone idle and not have to worry about paying for the bill while I'm away.

I found that their coverage was also good for what I was paying, since it was pretty robust on the east coast. The only negative side for me was that there would then be almost no coverage when I visited the west coast, but I didn't mind too much.

When the service is good, though, it is good. Something I was worried about when trying out Tello was that because of its status as an MVNO, the service I would be getting would be second-rate. This could not have been more false, as I was delighted to find that the service I was getting was pretty strong.

In terms of data, it was a similar story; the nationwide 4G network that Tello boasts is pretty fast and allows you to surf the web at lightning speed in areas that have coverage. My phone is typically on wifi at work, so I didn't take full advantage of this, but noticed it heavily when traveling on the subway or using my phone in public over the weekends.

The data that they give you isn't necessarily the most, though. For about $14 per month I had 1GB which was certainly sustainable, but I did feel like there was an upper limit at some point. At the end of the month I ran out of data and was subjected to Tello's throttled 64 kbps speed which is actually half as slow as competing MVNOs, so that was a bit discouraging. This made the limit of the wifi feel real and almost inaccessible unlike other services I've used in which I'm able to

Tello Mobile Phone Plan Review

On my last pay-as-you-go phone plan I was paying about $10 for 1.5GB, so that feels a bit cheap on the part of Tello. Given that the same amount with Tello would get you only 500MB of data, a third of the other network, that could be deterring for some.

However, the service for telephone calls is better on Tello than it was on the previous pay-as-you-go provider I had. So, depending on which is more important to you (data or calls/texting), you might find your needs swaying you a certain way.

Something that users without unlimited talking plans will notice immediately is that Tello, unlike over MVNOs, doesn't have rollover minutes. However, there is a way that you can have your minutes roll over regardless, but you need to be using the “Build Your Own Plan” model. To do this, change your plan on the last day of the month to the next highest option (i.e. if you had 100 for talking last month, choose 200). Then the minutes will roll over to the following month, after which you can switch back to 100 at the end of the month. Continue doing this to save your minutes if you'd like, ad infinitum.

For me, though, I didn't need to necessarily do this with my month of Tello. I was on an unlimited talking plan, so it was a non-issue for me.

One of the most relieving things to know, though, about Tello's service is that it actually uses the same network as Sprint. This means that I can enjoy the same coverage I got from Spring for only a fraction of the price I was once paying, which I think is really, really convenient.

A downside about Tello (and most MVNOs in general) is that there are no phone/data bundles that you can get. So, if you want to get a new phone, you'll have to pay full price to get it. If you're somebody who needs to get a new phone, then I might suggest looking into a different MVNO that has the best cell phone deals you can utilize. There are plenty of Verizon wireless deals that will meet this need. However, if you have a phone already and are not in the market for a new one, this is irrelevant.

That being said, though, there are some phones you can find through Tello that offer discounts—it's not just the same thing as the phone being free and coming with a certain amount of minutes like other MVNOs do.

Final Thoughts

All in all, I'm very happy with how Tello has given me an alternative to my Sprint contract that not only gets the same exact coverage as them, but does it for a fraction of the price. The downsides only really come when you stretch the limits of your service (i.e. going over your data limit and experiencing the slow crawl of the throttled data), but if you're the type of person who is able to control and regulate their usage, this is likely no problem for you.

The amount of data the service gives you is not as much worth the money as other services, period. However, if you don't need as much data and are simply looking for a cheap plan, then Tello is the plan for you.

That being said, there are also other services that give more data but don't give unlimited calling and texting, so it all depends on what your priorities are.

At the end of the day, I'm happy with my Tello plan and am relieved to have found a service that is affordable and flexible!

I also considered other MVNO options by reading Republic Wireless reviews and Tracfone reviews. I tried to look at Boost Mobile deals too.
