Don't know what type of proxy would fit for your needs? Here's some info about differences between residential and mobile proxies.
Residential proxies use IP addresses that providers give to "real" devices – PCs, laptops, etc. From the side of the target services, they have the highest level of trust.
Residential proxies are rotated. IP addresses change if the device is offline.
Mobile proxies use IP addresses that belong to the device connected to the 3G/4G network. They have the maximum degree of trust in the services. Most popular with web resources.
Froxy does not currently provide data-center proxies. But we are working on it!
