Internet in China: WhatsApp, VPN and eSIM Guide for Pakistani Travellers

It’s late. You’ve just landed in Beijing or Shanghai, someone back home is waiting to hear you arrived, and you open WhatsApp. Nothing loads. Google Maps is no help with the hotel address either, and the airport Wi-Fi login asks for an SMS code sent to a number you don’t have. Then a taxi driver says something you can’t follow, and the translator on your phone needs the very internet you’re missing.

It’s a common first-night story, and nearly all of it can be fixed before you leave Pakistan. This guide covers what stops working in China, why “I’ll sort it out when I land” falls apart, what buying a local SIM really involves, how to cope with translation when your data is dead, and where a travel eSIM helps and where it doesn’t.

We sell China eSIMs at Simless.pk, so we’re not a neutral voice. To make up for that, every fact below links to its source, the sources are listed at the end with the date we read them, and we’ve said where they disagree. This is a source-led guide, not a field test. It covers connectivity only: for the visa, payments and a route, read our China travel guide, and for data sizes see the China eSIM selection guide.

What actually stops working in China

The blocking happens at the national network level, so it isn’t something your phone, your Pakistani operator or an eSIM provider decides. The Government of Canada’s travel advice says China “blocks access to several websites, social media, search engines and online services within its territory” (source 11). Wikipedia’s list of blocked sites (source 1) shows the services in the table below. It describes itself as a dynamic list that may be incomplete, and Imperial College’s IT guidance (source 2) adds Google Maps, Gmail and Docs to the blocked services, so check again a week before you fly.

Why “I’ll sort it out when I land” goes wrong

None of the hurdles is dramatic on its own. Stacked on a tired night in a city where you can’t read the signs, they add up.

A VPN has to be installed, configured and tested, and Imperial’s IT team notes that VPNs are often blocked by networks (source 2), so you want to find that out at home on a normal connection. The maps, translation, ride and train apps that help most all work better with live data, and you need them in the first hour. Public Wi-Fi login pages can also ask for an SMS code, which needs a local phone number. And hosts and hotels often prefer WeChat to WhatsApp, so even a quick “I’ve arrived” message becomes a small puzzle if WeChat isn’t set up.

The local SIM route: what it really involves

You can buy a SIM in China, and plenty of travellers do. It just isn’t the quick purchase it is in many countries. Mobile numbers are registered to a verified identity: the BBC reported that from 1 December 2019 people in China registering new mobile services must have their faces scanned to match their ID (source 4), and an official Shanghai education FAQ from March 2024 says anyone activating a SIM must register under their real name and that visitors need a passport or a copy of it (source 5). Check the carrier’s current process before you rely on it. Expect a queue at the airport or a trip to a carrier shop in the city.

The local SIM does have one real advantage: it comes with a Chinese number, which some apps use for verification, and a data-only eSIM can’t offer that. Our guide to keeping your Pakistani SIM active while travelling covers the safe two-SIM setup.

Translation when you have no data

This is the one people underestimate. Picture yourself at a hotel desk or a taxi rank with a phone full of translation tools and no signal to run them. A little preparation turns that into a non-event.

1. Download the Chinese offline pack while you’re at home. Google says downloaded languages let you translate without an internet connection, and that camera translation may work for supported languages (source 6). Then switch on airplane mode and test it, because how much works offline depends on the app and your language.
2. Screenshot every booking. Make sure the hotel name and address appear in Chinese characters, so a driver can read them.
3. Save each hotel’s phone number in a note, in case someone has to speak to the driver for you.
4. Keep a second translator installed, such as the one built into your phone, as a backup.

Be realistic about Google’s live features: they rely on Google services, which Imperial’s IT guidance lists as blocked in China (source 2). The offline pack is the dependable fallback, and a live data connection is what makes everything else smoother.

What a travel eSIM fixes, and what it doesn’t

What it helps with

• Data without a SIM counter. You install the eSIM over Wi-Fi at home and switch it on after you land, following the plan’s activation instructions.
• Your Pakistani SIM stays in the phone for calls and one-time passwords.
• Plans on familiar networks. Our China catalogue lists plans on China Mobile, China Unicom and China Telecom partner networks, with 4G and 5G speeds listed (6 November 2026 snapshot). What your phone connects to depends on the plan, your device and your location.
• Payment in rupees. You order over WhatsApp, and the team confirms the plan and PKR price before you pay.

What it won’t do

It won’t promise access to blocked apps. Whether a roaming-based plan can reach WhatsApp or Google depends on how its traffic is routed, and we don’t guarantee it for any plan. It’s also data only, so there’s no Chinese number and no local SMS or calls; set up WeChat and Alipay at home with your Pakistani number. Some plans slow down after the full-speed allowance, and the fair-use line on each plan card says when.

If you carry an iPhone, check this first

Apple’s page for China (source 7) lists the iPhone 18 Pro, 18 Pro Max, iPhone Duo, 17e and iPhone Air as supporting eSIM in mainland China. It says other models, “including those purchased outside of China mainland”, can’t install an eSIM profile from carriers in mainland China, and that eSIMs from non-mainland carriers can’t be installed while you’re located in mainland China. That’s one more reason to install before you arrive. The page doesn’t say how a profile installed abroad behaves once you’re inside China on other models, so message our team with your exact model before you buy. Our list of iPhones that support eSIM and the compatibility checker cover the basics.

A simple countdown before you fly

1. About a week before. Check that your phone is unlocked and supports eSIM. Choose a plan on the China plans page, then set up WeChat and Alipay with your Pakistani number and link a card, as our China travel guide explains.
2. If you want blocked apps, sort the VPN now. Install it, open it and connect while you’re still in Pakistan.
3. Two or three days before. Install the eSIM over Wi-Fi, following our iPhone or Android steps, and read the plan’s activation rule first. When to install a travel eSIM explains installing versus activating.
4. The same days. Download the offline translation pack and an offline map in the app you plan to use, and screenshot your bookings with the Chinese addresses. Google says offline maps aren’t available in some countries or regions (source 8), so test the download for your cities before you rely on it.
5. On the day. Label your two lines, keep mobile data off on the Pakistani SIM, and turn on Data Roaming for the eSIM line when the instructions say to. Send one test message and open one map before you leave the airport, and save the Simless WhatsApp number.

How much data do you need?

Maps and messaging are light. Video calls home, photo backups and a VPN running all day are not. Our China eSIM selection guide has trip-length guidance and the trade-offs between daily and total-data plans.

Questions travellers ask

Does WhatsApp work in China?

Not reliably. Wikipedia’s list of blocked sites shows WhatsApp as blocked since September 2017 (source 1). OONI measurements also confirmed the block on one Chinese network from 23 September 2017 (source 9). Many visitors use WeChat for local contacts and a VPN for family chats. Whether any particular eSIM reaches it without a VPN depends on how its traffic is routed, and we don’t promise that for any plan.

Does Google Translate work in China?

The offline pack does, once you’ve downloaded it at home (source 6). Google’s online services are listed as blocked (source 2), so don’t count on live features. Test the pack in airplane mode before you fly.

Do I need a VPN if I buy an eSIM?

Only if you want the blocked apps. Plenty of trips run on WeChat, Alipay, Amap and Trip.com with just a data connection. China’s rules on VPNs are described differently depending on the source: Imperial’s IT guidance says VPN use “isn’t specifically banned” but advises against third-party VPNs (source 2), while Wikipedia says unauthorised VPN services were declared illegal in 2017 (source 3). The ministry notice from that month concerns licences for internet access businesses (source 10); we could not read its full text in English. We don’t recommend a product, so read the current official guidance and decide for yourself.

Can tourists buy a local SIM in China?

Generally yes, with registration at the point of purchase, and a passport is the usual document for visitors (source 5). That FAQ dates from March 2024, so confirm the current process with the carrier before you rely on it.

Will I get a Chinese phone number with a travel eSIM?

No. A Simless travel eSIM is data only, with no local number, SMS or calls. Use your Pakistani SIM for calls and one-time passwords.

The short version

China doesn’t have to be a connectivity headache, but nearly every fix happens before you board: the VPN if you want one, the offline translator, the Chinese-language screenshots and a data plan that’s ready to switch on when you land. If you’d like one less thing to queue for, a travel eSIM is a straightforward way to handle the data.
