MPTCP (Multipath TCP) is an extension of standard TCP that allows a device to use multiple network interfaces simultaneously for one connection. Simply put, it's like having several roads to the same destination, and you can distribute traffic across them, increasing overall speed and reliability.
In the context of tethering from a mobile phone, MPTCP can be useful when your carrier limits speed after you've used up your data allowance or blocks tethering. By using MPTCP, you can combine multiple channels (e.g., mobile data and Wi-Fi) to bypass these restrictions. However, it's important to understand that MPTCP is not a universal solution, and its effectiveness depends on the specific carrier and conditions.
The materials we reviewed mention various methods to bypass carrier restrictions, such as changing TTL, IMEI, and using VPN. MPTCP is another tool that can be useful in certain situations. For example, if you have two internet connections (e.g., mobile data and Wi-Fi), MPTCP can combine them to increase speed and stability.
However, it's worth noting that the provided materials do not contain detailed instructions on setting up MPTCP for tethering. Most advice focuses on changing TTL and IMEI, as well as using VPN to encrypt traffic. So, if you want to use MPTCP, you may need to search for additional information on your own.
In any case, remember that bypassing carrier restrictions may violate your tariff terms, and use these methods at your own risk.
