This iOS subscription import guide is for anyone setting up network acceleration on an iPhone for the first time. The process is more than pasting a URL into an app: the client must recognize the server protocol, parse the subscription, receive permission from iOS to create a VPN configuration, and then confirm that traffic is being routed as expected. If any step is incomplete, you may see “imported but unable to connect” or “connected but the exit location has not changed.”
Start by distinguishing three components. The client is the app installed on your iPhone that parses nodes and establishes the connection. The subscription URL provides the client with a list of routes and their parameters. A node is an individual connection profile available within the subscription. A subscription URL is not an ordinary web address or a single fixed node. Keeping these three concepts separate makes troubleshooting much easier.
Before you begin: Check the client, subscription, and system permissions
Proxy clients on iOS typically use Apple’s Network Extension capability to create a local VPN interface. What you see is the VPN status in the system status bar; behind the scenes, the client performs the protocol handshake, encryption, and traffic forwarding for the selected node. Whether the client supports the protocols in the subscription is therefore the first condition for a successful setup.
Common node protocols include Shadowsocks, VMess, Trojan, VLESS, Hysteria2, and TUIC. They use different formats, and no client should be assumed to support all of them. Shadowsocks, VMess, Trojan, and VLESS are widely supported across clients, but the specific transport layer, TLS, WebSocket, or Reality parameters still depend on the implementation. Hysteria2 and TUIC rely more heavily on UDP and QUIC, so older or lightweight clients may not parse them or establish a connection.
| What to check | What to confirm | What happens when there is a mismatch |
|---|---|---|
| Client | Supported subscription formats and node protocols | The import is empty, an unknown protocol is reported, or the node cannot be selected |
| Subscription URL | Copied in full and still valid | Download failure, authentication failure, or webpage content returned |
| iOS permissions | Permission for the app to add a VPN configuration | The connection stops immediately or repeatedly requests authorization |
| Current network | The Wi-Fi or cellular connection can access the internet | Every node times out and ordinary webpages also fail to load |
- ✅ Get the client from a trusted source and confirm that it is still receiving updates.
- ✅ Copy the subscription URL directly from the service panel to avoid manual transcription or truncation.
- ✅ Keep a basic network connection that can still access webpages while setting up.
- ✅ Note the current node name so you can verify it and troubleshoot after connecting.
- ❌ Do not mistake a single-node share link for a complete subscription URL.
Step 1: Get a compatible iOS client
Open the client download instructions in the service panel and check the currently recommended iOS client and acquisition method. App Store listings can vary by account region, app availability, and device system version, so your search results may not match the screenshots in this guide. Do not identify an app by its icon or a similar name alone; verify the developer, app description, and the entry point provided in the service documentation.
If a compatible client is already installed, open it first and confirm that you can reach its main interface normally. An app that has not been updated for a long time may lack support for newer protocols or transport methods. In that case, some nodes may remain unrecognized even if the subscription imports successfully. Before upgrading, check that existing configurations have been synced or backed up so local rules you still need are not overwritten.
What to look for in a client
For a first setup, you do not need the app with the most options, but these capabilities directly affect usability: importing and updating subscriptions from a URL; viewing node protocols or basic details; routing by domain, IP, or rule set; displaying connection logs; configuring DNS; and reconnecting after switching between Wi-Fi and cellular data.
Connection logs are especially valuable. Without them, “connection failed” leaves you guessing by repeatedly changing nodes. With logs, you can distinguish subscription parsing failures, DNS resolution failures, handshake timeouts, certificate validation failures, and unavailable UDP. Logs may contain server addresses or node names, so review and redact account credentials before sending them to support.
Step 2: Copy and import the subscription URL
After signing in to the service panel, open the subscription or client configuration page and use its copy function to obtain the complete URL. Return to the iOS client and look for “Subscription,” “Remote Configuration,” “Import from URL,” or a similarly named option. Labels vary between apps, but the workflow is the same: create a remote subscription, paste the URL, save it, and then update it.
- Copy: Click the copy button next to the subscription URL in the service panel. Do not paste it into a public search box or online note-taking tool first.
- Create: Open the client’s subscription management area and choose the option to add a remote configuration by URL.
- Paste: Make sure there are no extra spaces, quotation marks, line breaks, or Chinese punctuation at either end of the URL.
- Name: Give the subscription an easy-to-recognize name. The name is stored locally and does not change the server-side configuration.
- Update: After saving, refresh it once and wait for the client to finish downloading and parsing the subscription.
After a successful update, the node list should show recognizable details such as regions, routes, or protocols. If the client only says “subscription successful” while the list remains empty, do not proceed directly to connecting. Open the subscription details first and check the update time, response status, and parsing result. Some clients record incompatible formats in the logs while showing only a generic message on the main screen.
Why a subscription URL may look like garbled text in a browser
Subscription content is a machine-readable format for clients. It may be an encoded collection of nodes or a structured configuration. A browser may show a stream of characters, download a file, or display plain text when you open it directly; none of these necessarily means the URL is invalid. The real test is whether a compatible client can download and parse it. Conversely, if the browser shows a sign-in page, error page, or CAPTCHA, the client usually cannot recognize it as a subscription.
Do not edit parameters in the subscription URL or replace its protocol prefix with a more familiar-looking one. The server may return different configurations based on the client type, and manually removing parameters can cause authentication failures or change the format. To switch subscription formats, use the official options provided in the service panel.
Step 3: Choose a node and allow the system to add a VPN configuration
Choose a route from the node list that matches your current purpose. For the first test, there is no need to switch through several nodes. Select one node, complete system authorization, and establish a basic connection before comparing regions or route types. This keeps permission, client, and node issues from being confused with one another.
After you tap the connect button, iOS displays a system prompt saying that the app wants to add a VPN configuration. Confirm that the app matches the client you are using, then choose Allow. The system may ask for your device passcode or biometric authentication. This lets the client create a network extension configuration; if you deny it, the app cannot establish a system-level connection even if the nodes have already been imported.
After authorization, the client usually returns to its main screen and begins connecting. On success, the connection status changes and the VPN status in system settings updates as well. If tapping connect immediately returns to a disconnected state, check the client logs first rather than repeatedly deleting and reinstalling the app. Common causes include incompatible node parameters, UDP blocked by the current network, failed server DNS resolution, or a conflicting VPN configuration on the device.
Understanding direct, relay, and IEPL routes
A direct route connects the device straight to the destination server. Its path is simple, but performance depends more heavily on the public routing between your carrier and the destination region. A relay route first enters a relay gateway and then forwards traffic to an exit node, adjusting the cross-network path while still depending on the quality of both the gateway and exit. An IEPL dedicated route generally carries planned international link segments, with a focus on path stability; it does not make local network issues between the device and the gateway disappear automatically.
Route type is therefore only one factor when choosing a node. Video calls are more sensitive to sustained packet loss and jitter, web browsing to time to first byte, and file transfers to both path quality and server bandwidth. During first use, judge a route by whether it keeps your actual task stable rather than focusing only on the client’s momentary latency.
Step 4: Complete connection verification and check the exit, DNS, and routing
When the client shows “Connected,” it only means that the network extension has started; it does not prove that all traffic is passing through the expected node. Verify connectivity in order: basic access, exit address, DNS resolution, and routing results. Change only one variable at a time so you can tell whether the issue comes from the node, the rules, or the current network.
- Check basic access: Open a webpage that normally works and confirm that the connection has not cut off internet access entirely.
- Verify the exit: Use a trusted network test page to check the public exit region and confirm that it matches the purpose of the selected node.
- Check DNS: Run a DNS test and see whether resolution requests are handled by the expected resolver, rather than bypassing the client’s policy.
- Check routing: Visit destinations that should use a direct route and destinations that should use the proxy, confirming that the rules do not send all traffic down the same path by mistake.
- Switch networks: Switch between Wi-Fi and cellular data, then confirm that the client keeps or restores the connection.
A DNS leak usually means that application traffic is being forwarded through a proxy or VPN while DNS queries are sent directly through the local network. This can expose the domains being queried and may produce results inconsistent with the exit region. Check the client’s DNS mode, remote resolution settings, and routing rules rather than relying solely on results from a browser cache.
Routing rules determine which requests connect directly, which use a node, and which are rejected. Proper routing lets local services continue using the local network while destinations requiring international routes use the designated exit. When rules conflict, clients typically follow their defined matching order, so an overly broad rule near the top can override more specific rules below it. If you are unsure, start with the default rules provided by the service and add your own domain rules gradually.
- ✅ Both the system and client show a connected state, and ordinary webpages open.
- ✅ The public exit matches the target region of the selected node.
- ✅ DNS test results match the resolver settings in the client.
- ✅ Local services and international websites use their expected routes.
- ❌ Seeing a VPN icon does not prove that the exit or routing is correct.
Common errors and the recommended troubleshooting order
Subscription download fails or an authentication error appears
Copy the URL again from the service panel and check for spaces, line breaks, or punctuation. Then confirm that the subscription is still valid and try deleting and re-adding the remote subscription in the client. If the URL returns a sign-in or error page in a browser, the problem is usually not the node itself but an expired URL, changed credentials, or an unsupported request format.
Import succeeds but the node list is empty
This is often related to subscription format or protocol compatibility. Check the client logs for messages such as “unsupported,” “unable to parse,” or “unknown field.” Confirm that the client version recognizes Shadowsocks, VMess, Trojan, VLESS, Hysteria2, or TUIC configurations in the subscription. Do not use online conversion sites to process sensitive subscriptions; choose a compatible format in the service panel or use a client that clearly supports the format.
All nodes time out while connecting
Disconnect the client first and confirm that the current network itself can access webpages. Then test both Wi-Fi and cellular data to determine whether the access network is imposing a restriction. If only nodes using UDP or QUIC fail while others connect, the current network may be handling that traffic poorly. Choose a route compatible with the network instead of repeatedly changing certificates or server parameters.
The client says connected but webpages will not open
Temporarily restore the routing mode to the service’s recommended defaults, then check DNS. Common custom-rule problems include rejecting DNS requests, proxying the local network by mistake, or selecting a resolver that the current network cannot reach. You can also disconnect and reconnect to let the system rebuild the network interface. If basic access returns, add custom rules one by one to locate the conflict.
The connection drops after locking the screen or switching networks
iOS manages background network extensions based on system resources, network conditions, and app capabilities. Check whether the client offers on-demand connection or reconnection after network changes, and set those options to match your usage. Frequent drops can also result from failed node handshakes rather than the app being closed; use logs from around the disconnection time to determine the cause.
The original nodes disappear after updating the subscription
Remote subscriptions are maintained by the service, and the client replaces the old content with the latest list during an update. After route changes, an old node name or profile may no longer exist. Do not keep relying on local parameters copied from the old subscription, because certificates, domains, or gateways may have changed. Keeping the remote subscription and updating it regularly makes it easier to obtain valid configurations than using a static copy indefinitely.
Routine maintenance: Update subscriptions and protect your configuration
After the first connection is working, you do not need to re-import the URL every day. Keep the remote subscription in the client and use its update function to retrieve route changes. If the client supports automatic updates, enable them according to your usage frequency. If node names differ from those in the service panel, run a manual update before deciding that the issue is a cache problem.
Manage the subscription URL as an account credential. When changing devices, retrieve it again from the service panel rather than forwarding it through public chat history. When an old device is no longer in use, delete the subscription and local nodes from it. If you suspect the URL has been seen by someone else, reset its credentials in the panel and re-import it on every device that still needs access.
Custom rules also require maintenance. Website domains, service addresses, and network conditions change, so an outdated rule set may send requests down the wrong path. If a website suddenly behaves unusually, test with the default rules first. If the defaults work, inspect custom domain matching, DNS policy, and rule order instead of immediately assuming the node has failed.
At this point, the complete iPhone setup path is in place: the compatible client runs the network extension, the subscription URL syncs nodes, iOS permissions allow the VPN configuration to be created, and exit and DNS checks confirm that traffic is being forwarded as expected. When issues arise later, checking each layer in this path is usually more effective than uninstalling and reinstalling the app.
