How to share photos with your travel companions without using mobile data

Phone to phone, with nothing in between

At the end of a day out, everyone has the photos the others want, and sending them one by one through a chat uploads every file to the internet and downloads it again on the other phone. Nearby sharing skips that. Apple's security guide says AirDrop uses Bluetooth Low Energy and peer-to-peer Wi-Fi, and that the Wi-Fi radio talks directly between devices without any internet connection or wireless access point. Google says Quick Share works even without an internet connection, and Samsung describes sharing to nearby devices as a way to send files without using mobile data.

That is why it is the right tool on a trip. A long video from the boat goes from your phone to your partner's at full size and costs nothing from the data plan, even in a place with no signal at all. The only requirement is to be close together, with Bluetooth and Wi-Fi switched on.

AirDrop between iPhones, and the hotspot catch

Apple's steps: open Photos, tap Select, choose the photos, tap the Share button and then AirDrop, tap the person under People and ask them to tap Accept. Both iPhones need Wi-Fi and Bluetooth on, and if both run iOS 17 or later, you can simply hold them together to share.

One condition catches travellers out. Apple says that if either device has Personal Hotspot on, it must be turned off. On a trip where one phone shares its travel eSIM with the other, that is exactly the situation you are in. Switch the hotspot off, send the photos, and switch it back on; our guide to sharing mobile data with another phone has the steps.

If the other person is not in your contacts, their AirDrop has to be set to receive from everyone for a few minutes. Which setting to leave on the rest of the time is covered in AirDrop and Bluetooth settings for crowded places.

When AirDrop does use your data

Since iOS 17.1, Apple has let AirDrop transfers continue over the internet when you step out of range. Its user guide explains that if you leave Bluetooth or Wi-Fi range after a transfer has started, the transfer continues over the internet, and it warns that mobile data charges may apply.

Picture sending twenty videos at the hotel door just as one of you heads off to the station. On Wi-Fi, nothing changes. Away from it, the rest of the transfer goes over mobile data, and on a travel plan that comes out of the gigabytes you bought.

If you would rather keep AirDrop strictly local, Apple's route is Settings, General, AirDrop, and turn off Use Cellular Data. Transfers then only happen while you are close together, which for photos between people on the same trip is usually what you want.

Quick Share between Android phones

Google's steps: open the photo, tap Share, then Quick Share, and choose the nearby device. The other person has to have Quick Share open in Receive mode with the screen unlocked, and then taps Accept. Both phones need Bluetooth on, and on Android 12 or earlier, location as well. If a transfer fails, Google suggests bringing the phones within about 30 centimetres of each other.

Samsung's version adds Wi-Fi to the list: Wi-Fi, Bluetooth and Quick Share on, on both phones. It also draws the line on data clearly. Sharing with nearby devices does not use mobile data; sharing by QR code, by link or with contacts who are not nearby needs Wi-Fi or mobile data.

Google adds a setting worth knowing about. Under Quick Share settings there is an option called Use mobile data, and Google warns that if you are not on Wi-Fi, data charges may apply. On a trip, keeping it off avoids surprises.

An Android phone and an iPhone in the same group

Mixed groups used to have no direct option, and now some do. Google says Quick Share can send to an iPhone through AirDrop from a Pixel 8a or later and from certain Samsung, Oppo, OnePlus, Vivo, Xiaomi, Honor, Transsion and Motorola phones; the iPhone user sets AirDrop to Everyone for 10 Minutes and accepts the transfer in the AirDrop notification. Samsung lists only some recent Galaxy models for this, so check your phone before relying on it.

Without that support, Google offers a QR code route, and it is a different thing. Google says both devices need internet access and that the files stay available for 24 hours on Google's servers, protected with end-to-end encryption. In other words, the photos are uploaded and downloaded again, so on mobile data they count twice: once on the phone that sends and once on the phone that receives.

Chats, shared albums and links always count

Sending photos through a messaging app, adding them to a shared album or sharing a cloud link all work the same way: the file goes up to the internet and comes down again on the other phone. That is fine on hotel Wi-Fi and expensive on a small data plan, especially with video.

It counts double when the group shares one connection. If your partner is on your hotspot and you send them a video by chat, the upload from your phone and their download both come out of your plan. AirDrop or Quick Share does the same job for nothing.

A simple routine works for most trips: nearby sharing during the day, albums and backups at night on Wi-Fi. If you are still sizing a plan for a group, the Snoozim data calculator helps you estimate how much you will use.
