1. Metered gigabytes vs unlimited bandwidth
PacketStream's headline is $1.00/GB, and for a long time that made it the default recommendation for anyone who wanted cheap residential proxies without a subscription. It is genuinely inexpensive to start: you top up credits, you spend them, nothing expires, and there is no contract.
The catch is structural. Under a metered model, every page you load, every image your headless browser pulls down, and every retry after a failed request costs money. A scraping job that hits 100 GB in a month is a $100 bill, and a browser-automation workload that renders full pages — images, fonts, scripts and all — burns gigabytes far faster than most people estimate. Some PacketStream users have publicly reported bandwidth being counted more aggressively than they expected, which is a risk you only ever carry on a metered plan.
ProxyStream removes that variable entirely. You buy a mobile proxy for a window of time — 4 hours, a day, three days, a week, or a month — and the data is unlimited. Whether you push 2 GB or 2 TB through it, the invoice is identical. For anyone whose costs need to be predictable before the work starts, that difference matters more than the per-gigabyte rate ever could.
