Casino app data usage
Casino app data usage comes from three places: the one-off download, the games you open, and any live video you stream. The download is the only part with a published number (from 25.4 MB to 112.3 MB for our partner apps), while live dealer streams are by far the heaviest ongoing use. Operators don't publish per-hour figures, so check your phone's own counter.
Key takeaways
- Partner app downloads range from 25.4 MB (PlayOJO) to 112.3 MB (10bet) on iPhone; all five together come to 393 MB.
- Live casino and game shows stream video, so they use far more data than slots or RNG table games.
- Your phone's settings show exactly how much data each app has used and let you block mobile data for one app.
- If your connection drops mid-game, UK technical standards say a completed result should stand, and an interrupted stake should be returned.

How much data does a casino app use?
There isn't one number, and anyone quoting a precise 'MB per hour' for a named casino app is guessing, because operators don't publish it. What you can pin down is where the data goes, which parts are heavy, and how to measure your own use.
Think of it in three layers. First the app download, which is a one-off cost (plus updates). Then the lobby and the games, which load images, sounds and game files as you open them. Finally live video, which streams continuously for as long as a dealer table or game show is on screen.
This page is part of our casino app guides. For the storage side of the same question, see casino app storage space.
Casino app download sizes compared
The App Store lists each app's size, so this is the one part of casino app data usage you can compare precisely. These were the UK listing sizes in October 2026; PlayOJO's App Store listing (opens in a new tab), for example, gives 25.4 MB. Google Play didn't show comparable figures, and sizes change with each update.
| App | Type | Size | Share of 1 GB |
|---|---|---|---|
| PlayOJO Real Money Casino | Casino only | 25.4 MB | About 2.5% |
| Casumo Casino & Sports Betting | Casino and sportsbook | 52.5 MB | About 5.3% |
| Ladbrokes Casino Games & Slots | Standalone casino | 101.2 MB | About 10.1% |
| Coral Casino: Slots & Games | Standalone casino | 101.6 MB | About 10.2% |
| 10bet: Sports Betting & Casino | Sportsbook and casino | 112.3 MB | About 11.2% |
The share column uses 1 GB = 1,000 MB, the way mobile networks usually count. Downloading all five would use 393.0 MB (25.4 + 52.5 + 101.2 + 101.6 + 112.3), so on a 5 GB monthly plan that's just under 8% of your allowance before you open a single game.
PlayOJO's app is about a quarter of the size of Coral's or Ladbrokes', which matters on a tight plan or an older phone. Our smallest download casino apps list ranks them on that basis, and the PlayOJO app review covers the rest of the app.
What uses mobile data inside a casino app
Once installed, data use depends almost entirely on what you open. This is a rough guide to how different activities compare. The ratings are general, not measured figures for any app.
| Activity | Data demand | Why |
|---|---|---|
| Logging in, checking your balance, cashier | Low | Mostly text and small images |
| Browsing the game lobby | Low to medium | Lots of thumbnail images, often cached after the first load |
| Loading a new slot | Medium, mostly at the start | Game graphics and sound load once, then each spin sends little |
| Playing a slot you've opened before | Low | Files may already be stored on the phone |
| RNG blackjack or roulette | Low | Simple graphics and small result messages |
| Live dealer tables and game shows | High and continuous | Live video streams for the whole session |
| Watching sport in a combined app | High | Video streaming, as with live casino |
Slots built in HTML5 download their assets when you first launch them. That's why a new game can take a moment to load, while one you played yesterday may open faster. Clearing the cache frees storage but means those files download again; see how to clear a casino app cache.
Live casino data usage on 4G and 5G
Live casino is the main reason a casino app can eat into a mobile plan. Every live roulette spin or game-show round is a video stream, much like watching a video app, and it runs the whole time the table is open, even between bets.
How much it uses depends on the picture quality the stream picks, the length of the session, and your signal. Studios don't publish per-hour figures, so treat any number you see elsewhere with caution. Our guides on playing live casino on mobile data and does live casino work on 4G cover connection quality, and the live casino section of the Coral app shows what one partner lists.
Long live sessions also cost time and money, not just data. UK rules require casino games other than slots to allow at least 5 seconds per game cycle, and you can't play several games at once, but nothing stops a session running on. Set a time reminder before you start.
How to check a casino app's data usage on your phone
Your phone keeps a running total for every app, which beats any estimate. The menus vary slightly by software version and phone maker.
iPhone
- Open Settings and tap Mobile Data (or Mobile Service on some versions).
- Scroll to the list of apps; each one shows how much mobile data it has used since the counter was last reset.
- Turn the switch off next to any casino app you only want to use on Wi-Fi.
- At the bottom, use Reset Statistics at the start of your billing month to make the totals easier to read.
Android
- Open Settings, then Network & internet (or Connections), then Data usage.
- Open the app data usage list and pick the casino app to see its total.
- Turn off background data for that app if you don't want it using data while closed.
- Set a data warning or limit for the whole phone if your plan is small.
Wi-Fi or mobile data for casino apps
Home Wi-Fi is the obvious choice for big downloads, updates and live dealer games. Mobile data is fine for light use, such as checking a withdrawal or a quick look at your account.
Public Wi-Fi is a different matter. You are logging in to an account that holds money and ID documents, so a café or station hotspot is a poor place to do it. Mobile data is often the safer choice there. Turning on two-step sign-in where the app offers it helps too: the NCSC says 2-step verification (opens in a new tab) makes accounts harder to break into even if a password is known. More in public Wi-Fi and casino apps.
What happens to your bet if your data connection drops
Dropping signal mid-spin is the worry behind many data questions. The Gambling Commission's technical standard on interrupted gambling (opens in a new tab) (RTS 10) sets out how operators should treat you.
- If the bet was received and you can no longer affect the outcome, the result should stand, and a win should be credited.
- If a single-player game is interrupted before an outcome is generated, any deducted stake should go back to your balance.
- Games with several stages, such as a blackjack hand, should be restored to their last known state so you can finish.
- Operators must publish their policies on service interruptions.
So a lost connection doesn't usually lose you money on its own. Reopen the app and check your history. Our guides to what happens to a bet if your app crashes and how casino apps handle disconnections cover the detail.
Ways to cut casino app data usage
- Install and update apps on Wi-Fi only.
- Keep live dealer games and game shows for Wi-Fi.
- Stick to a few games you know, so their files are already on the phone.
- Turn off background data for casino apps on Android, and mobile data for them on iPhone if you only play at home.
- Pick a smaller app if your plan or storage is tight; PlayOJO's iOS app is 25.4 MB against 112.3 MB for 10bet's.
- Delete apps you no longer use rather than letting them update in the background; see how to delete a casino app.
The other kind of casino app data usage: your personal data
Some people searching for casino app data usage mean something else: what the app does with information about them. That is declared in the App Store privacy label and Google Play's Data safety section. Labels range widely: PlayOJO's iOS label lists only identifiers, while Casumo's lists financial info, contact info, usage data and diagnostics among other categories.
If that's the question you came with, read how casino apps use your data and casino app permissions explained.

Frequently asked questions
How much data does a casino app use per hour?
No UK operator publishes a per-hour figure, so the honest answer is that it depends on what you play. Slots and RNG table games use little once the game has loaded, while live dealer tables stream video continuously and use far more. Your phone's mobile data settings show the exact amount each app has used, which is more reliable than any estimate. For the live side, see how much data live casino uses.
Which casino app uses the least data to download?
Among our partners, PlayOJO's iPhone app is the smallest at 25.4 MB on the UK App Store, followed by Casumo at 52.5 MB. Ladbrokes (101.2 MB), Coral (101.6 MB) and 10bet (112.3 MB) are roughly four times bigger. Sizes change with updates, so check the listing before downloading. Our list of casino apps with the smallest download size compares them in more detail.
Does live casino use a lot of mobile data?
Yes, live casino is the heaviest data use in any casino app, because it streams video for the whole time a table is open. The amount depends on stream quality, signal strength and how long you stay. Studios don't publish per-hour figures. If your plan is limited, keep live tables and game shows for Wi-Fi and check your phone's data counter afterwards. Our guide to playing live casino on mobile data has practical tips.
Do slots use much data on a phone?
Slots use most of their data when you first open them, as the graphics and sounds load, and very little for each spin after that. A game you have played before may load faster because its files are already stored. Live features are the exception, as they stream video. If you want to keep use down, stick to a few familiar games. Our best slot apps list covers the partner apps for slot players.
Can I stop a casino app using mobile data?
Yes, both iPhone and Android let you block mobile data for one app. On iPhone, open Settings, then Mobile Data, and switch the casino app off; it will then work only on Wi-Fi. On Android, open the app's data usage settings and turn off background data, or restrict it further depending on your phone. This doesn't affect your account. See Android phones and iPhone device guides for more settings.
What happens if I lose signal during a spin?
Under the Gambling Commission's interrupted gambling standard, a bet that was received and can no longer be influenced should stand, with any win credited. If a single-player game is interrupted before an outcome is generated, the stake should be returned. Multi-stage games should be restored so you can finish. Reopen the app and check your game history. Our answer on losing signal during a spin explains more.
Is it safe to use a casino app on public Wi-Fi?
It's better avoided, because you are signing in to an account that holds money and identity documents. Mobile data is usually the safer choice away from home. If you must use public Wi-Fi, make sure you are on the official app, and turn on two-step verification if the operator offers it. The NCSC says 2-step verification makes accounts harder to access even if a password is known. Read public Wi-Fi and casino apps.
Do casino app updates use a lot of data?
They can, as an update may download a large part of the app again, and partner apps run up to 112.3 MB. Update sizes aren't published in advance. To protect your allowance, set the App Store or Google Play to update apps on Wi-Fi only. Don't skip updates altogether, though, as they carry security fixes. Our guide on how to update a casino app covers automatic and manual updates.
