How much data does a workday really use? I tracked mine

I’m a remote worker, and I’m jaded. I sit in my home office all day every day staring at the same four walls and trying to ignore my dog as she gives me those Bambi eyes, pleading to go out for another walk. Last night I had a revelation: I can work from anywhere.

A couple of hours later, I had a flight and an apartment booked in Cluj-Napoca, Romania. I leave in 10 days. It’s only for a week, but it’ll be my week. I’ll work in the mornings and explore in the afternoons. Then it hit me. What if the Wi-Fi’s lousy?

But it’s OK. I’m a tech-savvy entrepreneur. My phone can be my office. A hotspot will save the day, and I don’t use that much data anyway. Maybe 2 GB a day max? This morning I put it to the test. I reset my phone’s data counter, hotspotted my laptop, and worked my usual hours. I was wrong. Very wrong:

I was off by about 3 GB — more than two and a half times my guess. My phone plan gives me 20 GB a month. At this rate, I’d burn through it in four mornings. Clearly, my genius backup plan was somewhat lacking in the “genius” part.

I’d expected video calls to be the big data hog, and they did use more than any other single task. No wonder. According to Zoom’s own figures, an HD group call can use up to 2.6 Mbps, which is well over 1 GB an hour. What I hadn’t counted on was everything happening behind my back. A software update I didn’t ask for, plus Google Drive and Dropbox quietly doing their thing, used more between them than all my calls put together. In comparison, my email inbox — which gets more traffic than the 401 — barely registered. I suppose I’m not as tech-savvy as I smugly imagined.

My backup plan now needs its own backup.

The easy fix would be to find a café to work from, but I’m quite old and grumpy and don’t like being surrounded by people, especially when I’m working. The thought of being forced into one, or even worse, a coworking space, just doesn’t appeal. I know it sounds dramatic, but I don’t yuck your yum, so don’t yuck mine.

Thankfully, someone as stubborn as me won’t be held back from changing the world by something as inconvenient as running out of data. An eSIM is the obvious answer — but not just any eSIM.

The math doesn’t lie. Five mornings at 5 GB is about 25 GB, and that doesn’t include me deciding to have a night in streaming Netflix (old and grumpy, remember). Most eSIMs come in small per-GB packs. A 10 GB pack would be gone by Tuesday lunchtime. What I need is a global eSIM plan with unlimited data.

That search led me to Saily’s Ultra plan, which gives me 30 GB at full speed, comfortably covering my week with some left over for Netflix. If I somehow blow through all of that, it only slows down rather than cutting me off completely.

With my backup plan backed up, I’m ready to make my way around Transylvania as a proper remote worker. Looking at where the bulk of my data usage comes from, I’ll make a few quick tweaks to my setup when I arrive to make sure I’m not burning through GB unnecessarily.

Here’s the plan:

• Pause Drive and Dropbox sync while I’m on the hotspot.
• Switch off automatic updates, or set my hotspot as a “metered connection” so my laptop holds them back.
• Turn the camera off when I don’t need it, because audio-only calls use almost nothing.
• Download big files over Wi-Fi (even if it means going to a café for takeout).

So how much does your workday really use? Reset your counter tomorrow and find out. If you guess right, you’re officially more tech-savvy than me. Don’t feel too smug about it, though. I set the bar pretty low.
