Which proxy would work best for my youtube uploading needs?

I am looking to upload 2-3 1hr long YouTube videos per day on 5 separate YouTube channels from the same device and router. Would a static isp work for each channel ran through a anti detect browser? This seems like the most cost effect method as they claim to have unlimited bandwidth which is super important due to the length of the videos. If not what would you go for?

You could try SIM-based 4G proxies. Grab five LTE SIM cards and a multi-SIM router so each SIM gets its own static IP. Give each YouTube channel its own SIM, your uploads will look like real mobile traffic and stay smooth.

using residential or static proxies helps in connecting on interest location and make upload of videos to get listed on channel for viewers and page ranking.

Running 5 channels with 2–3 full-hour uploads daily from the same setup is totally doable, but your proxy setup needs to be solid. Static ISP proxies might work bandwidth-wise, but YouTube can be sensitive to IP reputation, and some static ranges are overused.
If you want smoother uploads without triggering trust issues, unlimited 4G/5G mobile proxies with API rotation are a better choice. They’re treated more like real users by YouTube, especially when paired with proper fingerprinting. You’ll reduce the risk of rate limits, shadowbans or verification loops, and get the bandwidth you need without throttling.

residential proxies for sure . you can use 4g proxies as well.

4G mobile proxies works best for me
