I understand that you are looking for methods to overcome data throttling on a USB modem or dongle used as a proxy. It's important to note that bypassing data throttling or restrictions imposed by your cellular carrier may violate their terms of service. However, I can provide you with some general methods that are known to help reduce the impact of data throttling. 1. Use a VPN: A Virtual Private Network (VPN) can encrypt your internet traffic, making it difficult for your carrier to detect the type of data you are using. Some VPN services offer features specifically designed to bypass data throttling. 2. Optimize your data usage: Minimize the amount of non-essential data you transfer while using your dongle as a proxy. Avoid bandwidth-intensive activities such as streaming HD videos or downloading large files excessively. 3. Use proxy servers: Utilize proxy servers that can route your internet traffic through different locations or networks. This may help in bypassing specific restrictions imposed by your carrier. 4. Modify User-Agent: User-Agent is a string of information sent by your browser to the websites you visit. By modifying the User-Agent to simulate browsing from a mobile device, you may be able to avoid detection and throttling. 5. Throttle-free plans: Some carriers offer special plans or packages that claim to provide unlimited or higher data speeds without throttling. You can inquire about these plans to see if they meet your requirements. It's important to note that these methods may not always be effective, as carriers regularly update their techniques to detect and impose restrictions on non-standard usage. Additionally, bypassing data throttling may be a violation of your cellular carrier's terms of service, which could result in penalties or termination of your service. Make sure to research and understand the legal implications before attempting any of these methods.
