A hotspot is an access point that turns your phone’s mobile data into a Wi-Fi network other devices can use. It doesn’t create data — it shares the data you already have. That’s why the question that actually matters isn’t what a hotspot is, but how much data each activity burns through it.
In this guide you’ll find the full hourly consumption table (Netflix, Zoom, Spotify, TikTok and more), how long a 5 GB plan lasts depending on how many devices you connect, step-by-step activation on iPhone and Android, and the mistake that makes a hotspot brutally expensive abroad.
A hotspot doesn’t create data. It shares it — and burns through it faster than you think.
Turning on your hotspot is free, but every device you connect eats into the same data plan. One hour of Netflix in HD costs 3 GB; a 1080p video call, 1.2 GB. With three people connected, a 5 GB plan can be gone in under two hours.
That’s why the useful question isn’t “what is a hotspot” but how much data does each activity consume. Below you’ll find the full table, plus how long your plan lasts based on how many devices you share it with.
What a hotspot is and what it’s for
A hotspot is a wireless access point that converts mobile data (or a wired connection) into a Wi-Fi signal that multiple devices can use — phones, tablets and laptops. It lets you share one internet connection across several devices at the same time.
There are two main categories:
- Mobile hotspots: portable devices, or the built-in feature on your smartphone, that share your mobile data over Wi-Fi. This is the most useful option when travelling or in areas with no Wi-Fi.
- Public Wi-Fi hotspots: access points in cafes, airports, libraries and hotels offering free or paid internet. Range typically varies between 30 and 300 metres depending on the antenna and power.
The key difference: a mobile hotspot consumes data from your own plan. A public hotspot doesn’t — but it’s a shared network with strangers and far weaker security guarantees.
How much data does a hotspot use? 2026 table
This is the question almost nobody answers with numbers. A hotspot doesn’t consume data by itself — it consumes whatever the connected devices are doing. And that bill comes out of your plan.
| Activity connected to the hotspot | Data per hour | Source |
|---|---|---|
| Netflix in 4K / Ultra HD | 7 GB | Netflix official data |
| Netflix in HD | 3 GB | Netflix official data |
| Zoom video call in 1080p | 1.2 GB | Industry benchmark |
| Netflix in standard definition (SD) | 1 GB | Netflix official data |
| Microsoft Teams group meeting | 500 MB – 1 GB | Industry benchmark |
| YouTube Music on high quality (256 kbps) | 750 MB | YouTube Music guide |
| Google Meet in HD | 500 MB | Industry benchmark |
| Zoom 1:1 video call in 480p | 400 MB | Industry benchmark |
| Watching TikTok videos | ≈ 400 MB | Instagram & TikTok guide |
| YouTube Music on normal quality (128 kbps) | 250 MB | YouTube Music guide |
| Google Meet audio only | 90 MB | Industry benchmark |
| Spotify on standard quality | 60 MB | Industry benchmark |
Consumption per hour, per device. Netflix figures come from Netflix’s official help centre; the rest are verified by HOLASIM — July 2026. If you connect two devices doing the same thing, consumption doubles.
Three takeaways from the table:
- Video is the enemy. A single hour of Netflix in 4K eats 7 GB — more than an entire week-long travel plan.
- Audio is almost free. You can stream Spotify on standard quality for 16 hours straight on 1 GB.
- Video calls sit in the middle, but explode in groups. A Teams group meeting can reach 1 GB per hour.
How long your plan lasts by number of connected devices
Here’s the blind spot of hotspots: consumption multiplies by the number of connected devices. If you and two other people stream video from your hotspot, you don’t burn 3 GB per hour — you burn 9.
| Activity | 1 device | 2 devices | 3 devices |
|---|---|---|---|
| Netflix in HD (3 GB/h) | 1 h 40 min | 50 min | 33 min |
| Netflix in SD (1 GB/h) | 5 hours | 2 h 30 min | 1 h 40 min |
| Zoom 1080p video call (1.2 GB/h) | 4 h 10 min | 2 h 05 min | 1 h 23 min |
| TikTok / social media (≈400 MB/h) | 12 h 30 min | 6 h 15 min | 4 h 10 min |
| Google Meet audio only (90 MB/h) | 55 hours | 27 hours | 18 hours |
| Spotify standard quality (60 MB/h) | 83 hours | 41 hours | 27 hours |
Estimated duration of a 5 GB plan based on how many devices you connect to the hotspot doing the same activity at the same time.
Before sharing your hotspot, it’s worth checking how much data you have left and working out how many GB you need per week of travel.
How to turn on your hotspot on iPhone and Android
On iPhone (iOS)
- Open Settings and go to Personal Hotspot (if it isn’t there, check that mobile data is switched on).
- Turn on Allow Others to Join.
- Tap Wi-Fi Password and set a password of at least 8 characters.
- On the other device, find your iPhone’s name in the Wi-Fi list and connect using that password.
On Android
- Go to Settings → Connections (or Network & Internet, depending on the manufacturer).
- Look for Mobile Hotspot, Portable Wi-Fi hotspot or Tethering.
- Turn on the hotspot and open its settings to set the network name and password.
- Choose WPA2 security or higher. Never leave the network open.
- Connect the other device by finding that network in its Wi-Fi list.
Three methods, three consumption profiles: Wi-Fi is the most practical and the biggest battery drain; Bluetooth is slower but battery-efficient; a USB cable is the most stable and fast, and barely uses battery because the phone charges while it shares.
Types of hotspot and which one suits you
- Phone hotspot: free, always with you. Ideal for occasional use or 1–2 devices. Drains battery and eats your data plan.
- Portable router (pocket Wi-Fi): connects 10 to 30 devices and has its own battery. Good for families, work teams or long trips, but it’s one more thing to charge and usually rented by the day.
- Public Wi-Fi hotspot: free, but shared. Fine for checking email at an airport, not for banking or sensitive work. Many use captive portals that require authentication before granting access.
- Private or paid hotspot: password-protected networks in hotels or coworking spaces. Safer than public ones, but tied to a fixed location.
For travellers and remote work, the combination that works best is a phone hotspot plus an eSIM with local data: you don’t depend on other people’s networks and you don’t pay roaming.
Using a hotspot abroad: the mistake that costs you
This is the most common and most expensive mistake: turning on your hotspot in another country using your home line. Every megabyte you share is billed as international roaming, and because the hotspot feeds several devices, consumption spikes without you noticing until the bill arrives.
The alternative most travellers use today is installing an international eSIM before leaving: you get local data the moment you land, you share your hotspot with no extra charges, and you know exactly what you’ll spend.
HOLASIM’s eSIM covers more than 200 destinations, installs in minutes from your phone, and never expires: install it once and top it up before each trip. See the plans on eSIM Global or eSIM for Mexico.
Frequently asked questions about hotspots
What is a hotspot?
A hotspot is an access point that turns a mobile data or wired connection into a Wi-Fi signal other devices can use. When you turn on your phone’s hotspot, the phone becomes a portable router and shares its internet with laptops, tablets or other phones.
How much data does a hotspot use?
A hotspot uses no data on its own: it uses whatever the connected devices are doing. One hour of Netflix in HD burns 3 GB, a Zoom call in 1080p burns 1.2 GB, and an hour of Spotify on standard quality only 60 MB. If you connect two devices doing the same thing, consumption doubles.
Does a hotspot drain the battery?
Yes. Keeping a hotspot active forces the phone to broadcast a Wi-Fi signal continuously, which noticeably reduces battery life. If you plan to share your connection for several hours, keep the phone charging or use a USB cable connection, which uses far less battery.
What is the difference between a hotspot and tethering?
Tethering is the generic term for sharing your phone’s connection with another device, whether over Wi-Fi, Bluetooth or USB cable. A hotspot is one of those methods: specifically, the one that uses Wi-Fi. Every hotspot is tethering, but not all tethering is a hotspot.
Can I use a hotspot abroad without paying roaming?
Yes, as long as you use an eSIM or a local SIM from the country you are in instead of your home line. If you turn on the hotspot with your home line abroad, every megabyte shared is billed as international roaming, and the cost can multiply tenfold.
How many devices can I connect to a hotspot?
It depends on the device. Most smartphones allow between 5 and 10 simultaneous Wi-Fi connections, while dedicated portable routers can reach 20 or 30. Keep in mind that the more devices you connect, the faster your data plan runs out and the slower each connection becomes.
