Claude VPN: Getting Ready for Uploads and Long Chats
Many people use Claude to read long reports, edit code and tidy up meeting notes, often uploading several files in one conversation. On a shaky connection, stalled uploads and cut-off replies break your train of thought. This page explains where HZVPN helps, and starts with the rule: Claude is only offered in regions Anthropic supports.

What a VPN does for Claude
Claude's website, desktop app and mobile apps all send your files and prompts to Anthropic's servers and stream the reply back piece by piece.
In regions Anthropic supports, HZVPN can encrypt that connection on shared networks, and give you another route to compare when uploads keep failing on your local line.
A steady line for PDFs and codebases
Large uploads take time, and a drop halfway means starting over. Before uploading, connect to an HZVPN location near you, try once with and once without the VPN, and keep the steadier one.
Editing contracts in a shared office
What you give Claude may include contracts or financial reports. On a shared network, HZVPN means the operator only sees encrypted VPN traffic, not which services you use.
Pick a location and stick to it
Changing IPs often can make your account need extra checks. Once you find a good location, keep it: in Singapore, for example, use Singapore (24 servers).
Write on the computer, read on the phone
Claude has a website, desktop app and mobile apps. One HZVPN account covers several devices at once: 3 on VIP, 5 on SVIP.
Claude and VPNs: three rules to know
These affect your account and your data, so read them before you start.
Only offered in supported regions
Anthropic publishes a list of countries and regions where Claude is supported. Using it outside that list may breach its terms and lead to account restrictions. Check Anthropic's official list to see whether you are covered.
Sign-up may need a phone number
Anthropic may ask you to verify a phone number when you sign up. The code travels over the mobile network, not a VPN, and a new IP does not change the country your number belongs to.
Uploads go to Anthropic
A VPN only encrypts the connection between you and the HZVPN server. Files and prompts still go to Anthropic and are handled under its privacy policy. For confidential material, check your company allows it first.
Ways to use Claude
The website, desktop app, mobile apps and developer API each behave a little differently on the network.
Website
Open Claude in a browser. The HZVPN app on Windows and macOS encrypts the whole computer's traffic, including the browser.
Desktop app
Claude's desktop app needs the internet too. With HZVPN on, its traffic also goes through the encrypted tunnel; check the connection is steady before big uploads.
Mobile apps
HZVPN runs on Android 9+ and iOS 13+. Switching between Wi-Fi and mobile data can cut off a reply that is still being written.
API and development
Developers calling Anthropic's API must follow the same supported-region rules. HZVPN's Linux command-line client works on servers, but don't use it to get around regional limits.
Get started in 3 steps
Sign up and download
Create an HZVPN account on our website, then download the app for Android, iOS, Windows, macOS or Linux.
Pick a server location
Choose one of 43 server locations in the app and tap connect. If it doesn't feel right, switch to another any time.
Open the app you want to use
In a region Anthropic supports, open Claude and upload a small file first; if uploads keep failing, switch to a nearby location or compare with HZVPN off.
Long-document upload failing? Check in this order
1. Start with the file: is its size and format within Claude's limits? If not, no network will get it through.
2. Disconnect HZVPN and upload the same file on your local network. If that fails too, the problem is most likely the local network or Claude itself.
3. If it uploads without the VPN but not with it, try another HZVPN location near you; each location takes a different route to Anthropic's servers.
4. Once the upload succeeds, avoid switching networks or server locations while a long reply is being written, so you don't have to regenerate it.

Frequently asked questions
Can I use a VPN to use Claude where Anthropic doesn't support it?
We don't recommend it. Using Claude outside the supported list may breach Anthropic's terms and lead to account restrictions. Go by the official list.
Claude wants a phone number at sign-up. Will a new IP help?
No. Phone verification looks at the number itself, not your IP.
With HZVPN on, can Anthropic no longer see my uploads?
No. A VPN only encrypts the connection between you and the HZVPN server; your files still go to Anthropic for processing.
Claude uploads keep failing. Is it the VPN?
Not necessarily. First make sure the file is within Claude's limits, then compare with the VPN on and off; if it fails only with the VPN, switch locations.
Does the Claude desktop app work through HZVPN?
Yes. With HZVPN connected on Windows or macOS, the desktop app's traffic goes through the encrypted tunnel too.
Ready when you are
Sign up for an HZVPN account to use the free servers. Upgrade later if you need more server locations or more devices online at once.
Server numbers come from our server list (43 locations, 265 servers). They change with maintenance; the app always shows the current list.
