If you've ever looked at an $80 monthly internet bill and thought about using your phone's hotspot instead, you're not alone. When my home ISP raised its price for the third time in two years, I decided to find out for myself. I unplugged my router, turned on my phone's hotspot, and lived this way for 30 days. I worked from home, streamed TV, and held video calls. Here’s what happened, what surprised me, and if I would do it again.
Why I tried it in the first place
I work from home four days a week. My internet bill had gradually risen to $89 a month for a mid-tier plan. My provider had just launched an "unlimited" plan that included hotspot data at no extra cost. On paper, the math looked simple. In reality, it was more complicated than I thought.
I set one clear rule for myself: the experiment would only "count" if I made no changes to my usual internet usage. No lowering video quality, no skipping calls, and no waiting for Wi-Fi at a coffee shop. If the hotspot couldn't keep up with my normal routine, that was the data point I needed.
- 30 Days fully hotspot-only
- ~68GB Total data used
- 4 Devices connected at peak
- $0 Extra cost on my plan
Speed and reliability: the honest truth
During the first week, I was truly impressed. My LTE connection regularly reached 40 to 60 Mbps for downloads, which was more than enough for Zoom, Slack, and 4K YouTube. Pages loaded quickly, uploads were decent, and I hardly noticed a difference from my old router.
Then week two came. Congestion during peak hours, roughly 7 to 10 PM, dropped speeds to single digits. One Tuesday evening, I ran a speed test and got 3.1 Mbps. That was fine for browsing but really uncomfortable for a video call. I had to reschedule a client meeting because of this. That’s when I started keeping a simple log.
Mobile hotspot data is usually given lower priority by carriers when towers are crowded, even on "unlimited" plans. This leads to slower speeds for hotspot users compared to regular data users during busy times.
What worked surprisingly well
Daytime work hours went very well. From 9 AM to 5 PM on weekdays, I had steady, fast connections that handled everything I needed. This included hour-long Zoom meetings with screen sharing. I also discovered that 5G coverage in my area, a mid-sized city suburb, was better than I expected. On days with a 5G signal, speeds often exceeded 150 Mbps, which is faster than my old cable plan.
Streaming worked well too. Netflix, YouTube, and Spotify never buffered during off-peak hours. I watched an entire season of a show without any interruptions. For casual use or light work, a hotspot could truly replace home broadband for many people.
Where it fell short
Three situations made the limitations clear. First, there was evening congestion. Second, large file transfers were a problem. I upload design files regularly, and a 2GB upload that usually takes about 8 minutes stretched to 35 minutes on a slow evening. Third, a firmware update on my laptop decided to download 4GB overnight. By morning, I had used nearly a quarter of my month's deprioritization threshold without even realizing it.
The battery drain on my phone was also significant. Running a hotspot constantly kept my phone warm and drained its battery by early afternoon. This meant I had to stay closer to a charger more than I wanted. A dedicated hotspot device would fix this, but it adds an extra cost.
What worked
- Daytime work hours, video calls
- Off-peak streaming, no buffering
- 5G speeds rivaled cable broadband
- No extra monthly cost on my plan
- Works great for travel or backup
What didn't
- Evening congestion tanked speeds.
- Large uploads/downloads are painful.
- The phone battery drained fast.
- Data cap anxiety on heavy days
- Rural/suburban signals are inconsistent.
Who should actually consider this switch?
After 30 days, my assessment is more complex than a simple yes or no. If you are a light to moderate internet user who browses, streams, and makes occasional video calls, and you live in a city with good LTE and 5G coverage, a mobile hotspot can definitely replace your home internet. You will save money, and you may not even miss your router.
If you work from home full-time, share your connection with several people, or frequently move large files, a hotspot is a reliable backup but a frustrating main connection. The evening slowdowns alone would likely drive most remote workers back to a traditional ISP.
One option worth considering is to maintain a basic ISP plan at the lowest tier for peak-hour reliability and use your hotspot to supplement it. In some areas, that combination can actually cost less than a single mid-tier cable plan.
Bottom line
A mobile hotspot is not a scam; however, it isn’t a full replacement for most households just yet. If your carrier has a solid unlimited plan with a good amount of hotspot data, it's a good idea to test it for a week before you ditch your broadband. The best situation is to have it as a reliable backup that you can depend on, not something you have to struggle with every evening.
Frequently asked questions
Is using a mobile hotspot all the time bad for your phone?
Running a hotspot continuously makes your phone generate more heat than usual and heavily drains both the battery and the processor. Over time, this sustained heat can slightly reduce battery capacity. If you plan to use hotspot data as your main connection, using a dedicated portable hotspot device is a better long-term option. It lessens the strain on your primary phone.
How much hotspot data do I actually need per month?
It largely depends on your habits. A solo user working remotely (video calls, browsing, email) usually uses 20 to 40GB per month. Adding streaming TV increases that to 50 to 80GB. A household of two to three people using it as their only internet connection can easily use over 100GB. Check your current home internet usage in your router's settings to get a realistic baseline before switching.
Can you use a hotspot for working from home?
Yes, but with some conditions. During business hours, hotspot speeds are generally fast and steady enough for most remote work tasks, including video calls and screen sharing. The main risks include evening congestion if you work late, data deprioritization if you go over your carrier's limit, and occasional dropped connections at crucial moments. It works, but it's less reliable than a dedicated broadband line for full-time remote work.
What's the difference between a phone hotspot and a dedicated hotspot device?
A phone hotspot uses your existing mobile data plan and shares your phone's connection with other devices. A dedicated hotspot (also called a MiFi or mobile router) is a separate device designed specifically for this purpose. It usually has a longer battery life, better antennas for signal, and supports more connected devices at the same time. Dedicated devices typically require their own data plan or SIM card, though some carriers let you add them to an existing plan for a monthly fee.
Is a mobile hotspot cheaper than home internet?
It can be, but it depends on your current phone plan. If your mobile plan includes unlimited hotspot data at no extra cost, then yes, cutting your home ISP saves you that entire bill. However, if you need to upgrade your phone plan or buy a separate hotspot plan, the costs change. Compare your total current cost (home internet plus phone) against what a new combined plan would cost. In competitive markets, carriers sometimes offer home internet replacement plans specifically designed to beat cable prices.
