# Mobile proxies: a carrier pool per GB, or a device of your own.

Real 4G/5G devices on real carriers. Rotate through the pool from $2.62 per GB, or rent a modem and decide yourself when its IP changes.


## Two modes

|  | Rotating pool | Dedicated device |
| --- | --- | --- |
| Endpoint | `mob.hodlproxy.com`, 9000 / 9001 | The device's own `ip:8000` / `ip:8001` |
| IP behaviour | New carrier IP per connection, or sticky with `-sid-` | One IP, yours alone, changed when you say so |
| Targeting | `-cc-`, carrier with `-asn-`, `-sid-`, `-ttl-` | Fixed at the order: country and carrier |
| Billing | Per GB, from $2.62, same rate in every country, never expires | Per device per term (24 hours, 30, 60, 90 days), by country; unlimited traffic |
| Best for | Collection at scale from mobile-first targets | Accounts and flows that must keep one phone-like footprint |


## The rotating pool

Everything on [Targeting & sessions](https://hodlproxy.com/docs/username-parameters) applies to `mob.hodlproxy.com`. Pick the country with `-cc-`; pick a carrier with `-asn-` and its AS number, listed on each [country page](https://hodlproxy.com/locations); hold an IP with `-sid-`. Carrier addresses are shared by thousands of subscribers behind NAT, which is exactly why targets tolerate them.

```bash
# Any US carrier, new IP per connection
curl -x http://USER-cc-us:PASS@mob.hodlproxy.com:9000 https://api.ipify.org

# Deutsche Telekom (AS3320), held for 15 minutes
curl -x http://USER-cc-de-asn-3320-sid-m1-ttl-15m:PASS@mob.hodlproxy.com:9000 https://api.ipify.org
```


## Dedicated devices

A dedicated device is a physical modem with an unlimited carrier plan, hosted in the country you chose. It is delivered like any dedicated proxy, as `ip:8000` and `ip:8001` with its own credentials, and it serves you alone for the term. Traffic is unmetered. Prices depend on the country because plans, hardware and hosting do; the United States and Canada are the reference.


## Rotating the IP of a device

You control when a device takes a new address from its carrier. Three ways, all returning the new IP:

| Method | How | Use it for |
| --- | --- | --- |
| Rotation link | A signed URL shown in the dashboard; a simple `GET`, no token needed | Anti-detect browsers, schedulers and tools that can only call a URL |
| API call | [`POST /v1/devices/{id}/rotate`](https://hodlproxy.com/docs/api#post-v1-devices-id-rotate) with your Bearer token | Your own code, before a new session starts |
| Timer | `rotate_every_minutes` on the device, set in the dashboard or with [`PATCH /v1/devices/{id}`](https://hodlproxy.com/docs/api#patch-v1-devices-id) | Hands-off jobs that want a fresh IP every N minutes |

```bash
# On demand, from your code
curl -X POST https://api.hodlproxy.com/v1/devices/dev_8k2m/rotate \
     -H "Authorization: Bearer TOKEN"

# Read the current IP
curl https://api.hodlproxy.com/v1/devices/dev_8k2m -H "Authorization: Bearer TOKEN"
```

- A rotation takes a few seconds. Connections in flight through the device are dropped; open new ones once the call returns.
- The new address comes from the same carrier and country. Carriers recycle addresses, so a rotation can occasionally return an IP the device held before.
- Rotations are unlimited and free. Rotate when the platform would expect a change (a new session, a new day), not on every request.


## Best practices for accounts

- One account per device, in the account's home country and on a carrier its audience actually uses.
- Keep the browser profile and the device together; moving an account between devices or countries is what triggers verification.
- Rotate deliberately: a new IP per session looks like a phone; a new IP per action does not.
- For scheduled posting on many accounts, the pool with short sticky sessions is often enough; reserve devices for the accounts that matter most.
