Let's do some math
You're in the USA and you want an unlimited residential or 4G proxy for whatever reason (sneakers, SEO, IG, etc.) You have 2 options. Buy or build your own.
Over the course of a year the cost of building your own will be:
| Hardware costs: | $100 |
| SIM card: (Unlimited AT&T through a special method) | $35/Month * 12 = 420 |
| Total: | $520/Year |
So, an unlimited 4G/residential proxy will cost you around $500/year and is technically risk-free, since you can sell the hardware anytime.
On the other hand,
if you were to buy a US 4G proxy, the average is about $100/Month which is $1,200/Year and comes with a lot of risk including sharing the proxy without your permission, logging your data, etc.
So we can conclude:
| Cost of building your own proxy: | $300-$600/Year |
| Cost of buying a 4G proxy: | $1,200 - $2,500/Year |
This is per dongle using this particular script.
To be honest, it highly depends on the cost of 4G data in your country, even so, I know people in Canada and Australia who are still running their own 4G proxies even though data is relatively expensive. It just depends on whether you care about absolute quality or not.
In my opinion, the quality alone is worth building your own 4G mobile proxy.
