Yes, you can play Fallout Shelter offline. Bethesda's own support page says an internet connection is only needed to download the game, and once it's installed it doesn't need internet access. The Google Play listing also describes it as an offline base building game.
Fallout Shelter is one of those rare mobile games that's happy with no signal at all. You run an underground vault, and the vault doesn't care whether you're on Wi-Fi, a train or a plane.
Below is what Bethesda's help page and the two app store listings say, what still needs a connection, and a few habits that keep an offline vault running smoothly.
The official word from Bethesda
| Source | What it says |
|---|---|
| Bethesda Support | Internet only needed to download; once installed, no internet access needed |
| Google Play listing | Describes an offline base building game |
| Google Play labels | Bethesda Softworks LLC, 50M+ downloads, rated Teen, Contains ads, in-app purchases |
| App Store listing | Bethesda Softworks LLC, 647.6 MB, rated 13+, in-app purchases |
That's about as clear as an official answer gets. The help article asks the exact question, and the answer starts with a plain no: you don't need a connection to play.
What the internet is still needed for
The download itself, first of all. On iPhone the App Store lists the game at 647.6 MB, so grab it on Wi-Fi rather than mobile data. Updates also arrive through the store, and you'll need a connection to fetch those.
The Google Play listing shows a Contains ads label and in-app purchases. Anything that relies on an ad loading or a store page opening won't work while you're offline, so expect those parts of the game to wait until you're back online.
Getting a vault ready for a journey
- Install the game and open it once at home on Wi-Fi.
- Let any update finish before you leave.
- Switch to airplane mode and launch it, so you know it works without a signal.
- Charge your phone; base building games keep the screen busy.
- If a child's playing, set the store to require approval for in-app purchases before you go.
Phone or tablet, Android or iPhone
The answer is the same on both stores. Bethesda's help article doesn't split it by device; it simply says the game doesn't need internet access once it's installed. The Play listing calls it offline, and the App Store listing is from the same seller.
Age ratings differ slightly in wording: Google Play rates it Teen, and the App Store rates it 13+. Both point to the same thing, a game aimed at teenagers and adults rather than young children.
Why an offline vault suits travel
A lot of base building games need a constant connection, because they're built around raids from other players or a shared world. Fallout Shelter's listing frames it as your own underground adventure, which is part of why it can run without a signal.
That makes it a calm pick for a flight. You can check in on your vault, rearrange it and carry on building, then put the phone away. It's the kind of game that fits around a journey rather than demanding all of it.
Keep in mind that the listing and the help page describe how the game is meant to work. If something behaves differently after an update, Bethesda's support site is the place to check first.
If the game won't open offline
Bethesda's answer is clear, so if the game refuses to start without a signal, the cause is usually something on the device rather than the game's design. The most common one is an update that started but never finished.
- Reconnect to Wi-Fi and let the store finish any pending update.
- Open the game once while you're online, then close it.
- Switch to airplane mode and try again.
- Restart the phone if it still hangs on the loading screen.
- Check Bethesda's support site if none of that helps.
It's also worth keeping some free storage on the phone. A game that's 647.6 MB on the App Store needs room to update, and a nearly full phone can stop an update halfway.
Offline play and younger players
Offline doesn't mean the ads and the in-game shop go away. The Google Play listing shows both a Contains ads label and in-app purchases, and they'll come back as soon as the phone reconnects. If you're lending the phone to a teenager for a trip, set up approval for in-app purchases before you hand it over.

I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
The Teen and 13+ ratings are worth respecting too. They're the stores' guidance, not mine, and they're the simplest way to decide whether a younger child should be running a vault.

My answer in one line
Download Fallout Shelter at home, open it once, and you're free to run your vault anywhere. Bethesda says so itself, and that's the best source you'll find.
