Mobile Internet is enabled and stable.

The tariff supports distribution (no blocking)

The battery is charged ≥30% or the phone is charging

VPN/proxy disabled

Free ≥1 GB of traffic (if limited tariff)-->

2. Method 1: USB modem (the fastest and most economical)

Connection via USB cable - the best option if you need maximum speed and minimal battery consumption. This method works on all versions. Android (starting from 4.0 Ice Cream Sandwich) and does not require additional programs.

⚡ Pros:

• 🔋 Minimal battery consumption (phone charges via PC)
• 🚀 Speed ​​is close to maximum (limited only by the tariff)
• 🔒 Reliable connection without interference

⚠️ Cons:
