In the last 48 hours, the community has been actively discussing how to bypass carrier restrictions on internet tethering from mobile devices. Users shared methods to circumvent carrier bans and continue using the internet on other devices.

The main problem users face is carrier detection of tethering. Networks use various technologies such as TTL (Time To Live) analysis, IMEI, and DPI (Deep Packet Inspection) to determine if traffic is being shared from one device to others. If the carrier detects tethering, they may throttle speed or require additional payment.

One of the most popular methods is changing TTL. TTL is a parameter that decreases at each router hop. If packets from one device arrive with different TTL values, it indicates tethering. To hide this, users fix TTL to a specific value (e.g., 64 or 128) on the tethering device or change it on receiving devices. The materials mention various ways to change TTL: on routers (e.g., Keenetic, OpenWRT), on PCs with Windows, Mac, Linux, and on Android and iOS.

Also discussed is changing IMEI — the unique device identifier. If a SIM card is intended for phone use, but you insert it into a modem or router, the carrier may block tethering. In this case, changing IMEI to a smartphone IMEI (preferably from a Windows Phone if tethering to a Windows PC or Xbox) helps.

To bypass p2p traffic blocks (e.g., torrents), it is recommended to use VPN or other encryption technologies that hide traffic content from DPI.

The materials also mention specific solutions for different carriers: MTS, Beeline, Rostelecom, Tele2, MegaFon, Yota, as well as Vodafone Ukraine and MTS Belarus. For example, for Tele2 it is important to use a real IMEI from an Android smartphone, not a generated one.

Additionally, methods for Keenetic routers and Huawei, ZTE modems are discussed. For Keenetic, there are special instructions for fixing TTL, and for modems, ready-made firmware.

Please note that these materials are discussions of technical methods, and their use may violate the terms of your contract with the carrier. We do not encourage breaking rules, but merely inform about existing discussions.
