Wait. Is a Discount Tello Plan as Good?

Tello vs – Tello can feel just as fast as T-Mobile most of the time—until you’re in weaker signal areas, where latency and uploads dip and speed tests time out. The trade-off is a cheaper plan with fewer perks for travelers, international texting, and phone upgrade suppo

I didn’t notice much at first. In the comfort of home, my cellular 5G data on T-Mobile usually lands around 800 to 900 megabits a second—and with the Tello phone it was about 30 percent slower. Even then, both speeds are firmly in 5G territory.

Streaming wasn’t a problem. I had no trouble pulling up my usual dose of Josh Johnson comedy, and the speeds were well beyond anything you’d realistically need for 4K video.

But when the connection got harder, the difference showed up.

Latency was significantly higher overall on Tello. It wasn’t enough to ruin a casual game like Royal Match. but it could matter if you’re the kind of user with higher demands. The download numbers were also lower than T-Mobile in the same locations. just not by a whole lot—until you compare the moments when reception degrades.

Upload speed was the one surprise. With the Motorola Razr, uploads were actually faster on Tello than with an old iPhone on T-Mobile. After checking with my colleague Julian Chokkattu. who has covered phone advances for years. the likeliest explanation is improved modem performance in the newer Motorola—not some secret backdoor that’s making Tello uploads unusually fast.

Still, the real story of Tello’s performance starts outside the easy zones.

In areas with degraded or 4G reception, lapses became noticeable. Near the forested northwestern ridge in the outskirts of Portland, Tello showed fewer bars than T-Mobile. Data arrived at speeds slow enough to bother me, and a couple of speed tests timed out.

Uploads were affected there too. In low reception areas compared to my T-Mobile phones. upload performance slowed dramatically—sometimes dipping down to only a quarter of T-Mobile’s network speed. In other words: Tello often works just as well as T-Mobile. but the times when it doesn’t tend to be the times when you’re asking the most from your phone—clinging to a stray bar of reception. or trying to stream while riding a train.

That difference is where the decision gets personal.

If you travel a lot, the trade-offs stack up. Family discounts tend to be better with big providers. Frequent international travelers should also probably stick with the bigger carriers, since international roaming will cost you with Tello.

Tello also won’t match the texting experience travelers expect. International texts to and from most countries outside Latin America and Europe cost you, and travel is when you’re most likely to chew through lots of data outside Wi‑Fi networks.

Then there’s the phone itself.

With Tello, you’re on your own when it comes to procuring a device. T-Mobile and other postpaid plans, by contrast, tend to keep you tied to their higher-priced plans by offering the latest phones at steep discounts—something that can matter a lot if you upgrade often.

So the headline is simple: Tello can be perfectly fine—sometimes even surprisingly strong on uploads with newer hardware—but its weaker moments arrive right where reliability matters most: thin reception. the edges of coverage. and the high-demand situations that make you notice latency and stalled tests.
