Per device, per month.
Never per gigabyte.

Yes. The plan belongs to the device, so each phone is set on its own and a mixed fleet is the normal case — a Seed phone holding one steady IP next to Farm phones running multi-level policies and Turbo. Every device enforces its own capabilities and draws its own price from the balance each cycle, so you pay the higher tier only on the phones that earn it. If one phone needs multi-level policies, that phone moves to the Farm Plan and the rest of the fleet stays where it is.

One paired Android phone, stock, no root needed. It needs a SIM with a data plan to hold a mobile carrier IP, or it can egress over WiFi instead. Each device exposes SOCKS5 on a base port and HTTP on the next port up, and how many proxies it can run at once is set by the plan on that device.

You put a balance on the account before you subscribe, then pick a plan. Each cycle every paired device draws its plan price from that balance, one draw per phone. There is no card on file and no monthly charge to approve, so the balance only ever moves when a device fee comes out of it.

Endpoints keep serving through a grace window after the balance reaches zero. Top up inside that window and nothing on the fleet changes. If it closes with the balance still empty, endpoints suspend and stop accepting traffic until you top up. Your devices, credentials and policies stay in place the whole time.

Yes, on any phone, and it takes effect immediately in both directions. A change refunds the unused remainder of that device's current period to your balance and buys a full period of the new plan. An upgrade simply unlocks the new capabilities. A downgrade lands at once as well, which means anything the smaller plan cannot carry is unwound as part of the switch: proxies beyond the new limit are removed, Turbo and timed rotation switch off, and policy assignments in scopes the new plan does not have are dropped. The dashboard lists exactly what a change will remove before you confirm it. A phone still inside its free trial keeps the trial, and only the plan it converts to changes.

Your first device on the Farm Plan runs free for seven days, with no credit card and no balance required. The seven days start the moment you pair a phone rather than when you sign up, so you can set the account up now and start the clock when you are actually ready to test. That one phone gets the full Farm Plan feature set — Turbo mode, multi-level policies, SMS webhooks and rotation over the API — and nothing draws down until the trial ends. Each handset gets one trial: pair a phone that has already used one and it works normally, it just bills from the start. Devices beyond the first, and devices on another plan, are charged from the moment you add them.

Really. There is no gigabyte meter, no overage line and no throttle that fires at a threshold. A device that moves a terabyte draws exactly what a device that moves nothing draws. The only real ceiling is the phone: its carrier plan, its radio, and the request rate on your plan, 5/s per proxy on the Seed Plan, 15/s with a burst of 50 on the Grower Plan, 50/s with a burst of 200 on the Farm Plan, and no rate cap at all on the Enterprise Plan.

On fleet size, relay regions and contract term, which is why there is no published figure. Tell us roughly how many devices you run and where traffic needs to exit, and you get a figure on the first call. The Enterprise Plan bills by invoice, annually or quarterly.
