# FAQ

## General

**What is EProxies?**
EProxies is a global proxy network offering 72M+ residential IPs across 195+ countries, providing reliable proxy infrastructure for data collection, multi-account management, ad verification, and more.

**What types of proxies do you offer?**
Four products: Residential, Unlimited Residential, SOCKS5, and Static Residential. See the [product overview](https://www.eproxies.io/docs).

**Are the IPs ethically sourced?**
Yes. All residential IPs come from real devices with explicit user consent. We comply with applicable data protection regulations and maintain transparent data handling practices.

**Is there a free trial?**
Yes. Free accounts include a limited amount of trial traffic so you can evaluate performance, speed, and tool compatibility before buying.

**Which countries are supported?**
195+ countries and regions, with city-level targeting in major markets. See [Geo-Targeting](https://www.eproxies.io/docs/usage/geo-targeting).

## Billing & payments

**Which payment methods do you accept?**
Cryptocurrency (USDT/BTC/ETH/TRX/LTC), Alipay (CNY/HKD), and credit cards (Visa/Mastercard). See [Purchases & Payments](https://www.eproxies.io/docs/account/billing-and-payments).

**How are residential proxies billed?**
By transferred traffic (GB). Buy a traffic package and use it within its validity period; unused traffic carries over for as long as the package is valid.

**Can I upgrade or downgrade my plan?**
Upgrades take effect immediately and you only pay the difference; downgrades take effect at the next billing cycle.

**What is the refund policy?**
Refunds are available within 3 days of purchase if less than 20% of the plan has been used. See the [refund policy](https://www.eproxies.io/docs/account/billing-and-payments).

**Is there enterprise pricing?**
Yes — volume discounts, SLA guarantees, and a dedicated account manager. [Contact sales](https://www.eproxies.io/company/contact) for a quote.

## Technical

**Which protocols are supported?**
HTTP, HTTPS, and SOCKS5 on the same gateway and port (`proxy.eproxies.net:23333`). Whichever protocol your client connects with just works.

**How do I integrate?**
After purchase you get credentials (host, port, username, password) — plug them into your program or tool. We provide [code examples](https://www.eproxies.io/docs/usage/code-examples) for Python, Node.js, Java, Go, PHP, and cURL.

**What is the average response time?**
Residential proxies average under 0.6 seconds; actual times vary with the target site and geographic distance.

**Do you support sticky sessions?**
Yes — the same IP can be held for 1–120 minutes. See [Session Control](https://www.eproxies.io/docs/usage/session-control).

**How does IP rotation work?**
By default every request is automatically assigned a new IP, handled entirely by the proxy gateway. When you need a fixed IP, use the sticky session parameters.

**My proxy will not connect — how do I troubleshoot?**
Check in order: (1) verify your credentials with [cURL](https://www.eproxies.io/docs/usage/code-examples); (2) confirm your plan still has traffic (dashboard overview); (3) check the username parameters for typos (the most common one is a missing `-pool-flow`); (4) in whitelist mode, confirm your exit IP is on the whitelist. If it still fails, contact [technical support](https://www.eproxies.io/docs/support).
