Hotel and Airport Wi-Fi in Asia: Who Caps Your Devices, and Who Never Says

The airports we read ask for nothing or for an email address, and none publishes a device cap. Hotels are where a count can stop your fifth device, and the chains’ terms never mention a number, so any cap is the hotel’s own.

Everything below was read on 2 October 2026 from the airports’, hotels’ and manufacturers’ own pages.

What the airports publish

Changi is the most explicit: “You do not need to register, pay, or provide personal information to access the complimentary internet connection during your visit.” Hong Kong’s page says “No registration is required.”

With no account, nothing is counted across your devices. Each one clicks through the login page by itself, so a family of five at Changi makes five separate connections. Every device has to reach that page in a browser, which an e-reader or games console may not manage.

Suvarnabhumi asks for more. Its page says to enter your email, accept the terms, and “you can use the wireless internet immediately for 60 minutes.” It does not say whether the 60 minutes belongs to the email address, the device or the day, or what happens when it runs out.

Narita’s page recommends a VPN: “Those seeking a secure connection are recommended to use a VPN (virtual private network).” Our habits for departure-hall Wi-Fi explain why.

Hotel chains do not count devices in their terms

We read the programme terms of two of the biggest hotel chains, Hilton Honors and Marriott Bonvoy. Neither uses the word “device” anywhere.

Hilton promises “Complimentary in-room and lobby standard WiFi internet access” to members across its brands, and premium WiFi to Diamond members, on a confirmed reservation made through the channels Hilton lists. Neither tier has a device number.

Marriott limits the benefit per room: it “is limited to one (1) guest room per eligible Member per stay regardless of how many rooms have been reserved.” In this region the membership matters less than elsewhere, because the terms name “properties in the Asia Pacific region which offer complimentary in-room internet access to all guests, regardless of booking channel.” It gives no device count either.

The number is set hotel by hotel, and most hotel pages we read do not publish it. Three Dorsett hotels in Hong Kong say different things:

The Capitol Hotel Tokyu in Tokyo publishes no number. For how to connect, its page says “Please ask the Front Reception or a member of staff.”

How a hotel tells your devices apart

A hotel that caps devices needs a way to count them. GL.iNet, which makes travel routers, describes the common one in its support pages: “Some hotels limit the number of devices each customer can connect to the hotel’s Wi-Fi by recognizing their MAC addresses, and they record the device’s MAC address when it first connects.”

Apple’s support page says an iPhone “identifies itself to each network using a different Wi-Fi address, and might rotate (change) the address periodically.” On a network with weak or no security, the default is Rotating, which changes “every 2 weeks”, and making the phone forget a network can give it a new address next time.

Apple’s page does not mention hotels, so this is our inference: on a hotel network that counts addresses, forgetting the network to fix a connection may make your phone look like a new device and use a second slot. On iOS 18 or later you can set that one network’s private address to Fixed instead.

A travel router turns the room into one device

GL.iNet’s page says some hotel networks “limit access to, for example, two devices”, and “The hotel Wi-Fi will only recognize the travel router as a single device”. Everything else joins the router. How a router changes your VPN count covers the VPN side. These are the hotel-side catches:

The VPN has to be off while the router logs in. GL.iNet’s troubleshooting steps for a login page that will not load include “Make sure all VPN connections are disabled”, then retrying the page. Turn the VPN back on once the router is online.

Its login helper is not private. GL.iNet’s automatic login mode for public hotspots “may leak your network activity to the hotspot provider (e.g. hotel or shopping mall)” while it is active.

A hotel that has already recorded your phone may refuse the router. GL.iNet’s fix is to copy the phone’s address onto the router, or to ask staff to approve the router, using its “factory default MAC address, not the random one”.

When your VPN’s own count matters

In the room, a router makes your VPN count smaller: one connection covers everything behind it. At the airport, where each device joins the free Wi-Fi alone, or in a café, it does nothing. So check the most devices running the VPN at the same moment, with each router counting as one.

For most travellers that number is well under ten, and any of the big VPNs covers it. NordVPN’s pricing page lists “Ten simultaneous connections on ten devices secured with one NordVPN account” on every plan. Proton VPN’s paid plan says “Secure 10 devices at a time”, and its free plan “Secure 1 device at a time”. If you already pay for one of these and stay under ten at once, keep it.

The count passes ten when a group shares one subscription across rooms. Four adults in two rooms with a router in each are at two before anyone leaves. If all four then work from a café with a phone and a laptop each, that is ten at once, and one tablet makes eleven. For that group, Surfshark, which publishes no device cap, fits: its pricing page says “You can protect as many devices as you like.”

Three things on Surfshark’s own pages narrow that:

• “Surfshark Antivirus service allows a maximum of five simultaneous connections per account”, so a bundle bought for antivirus stops at five.
• Its terms keep the right to limit “an immoderate number of simultaneously connected devices”, a clause aimed at resellers rather than a group of four, as our read of the unlimited clause explains.
• A free trial cannot test the group case: “if you use a free trial, you can only use it on 3 devices until the trial period ends.”

The hotspot and eSIM limits for a family cover the household case.

Before you check in

1. Ask the front desk how many devices one room can connect. The chain’s terms will not say.
2. Connect the devices that matter first, in case the hotel records addresses at first connection and the work laptop is left over.
3. Turn Wi-Fi off and on instead of making a phone forget the hotel network.
4. With a router, switch the VPN off, get past the login page, then switch it back on.
5. Count the most devices running the VPN at once, with each router as one. Over ten, compare Surfshark’s plans before renewing a ten-device subscription.

Not checked

We could not read a current official Wi-Fi page for Incheon or Kuala Lumpur, so they are left out rather than filled in from third-party sites. No airport page we read says whether it limits devices per person. We did not read IHG’s, Hyatt’s or Accor’s terms. How a hotel counts devices, if it does, is its own decision, and no chain we read publishes it.
