Lake Constance: Avoid the Swiss Roaming Trap

Reliable Connectivity for Kreuzlingen, Romanshorn, and St. Margrethen

⚠️ The "3-Border" Trap Explained

Traveling around Lake Constance (Bodensee) means you are constantly between Switzerland, Germany, and Austria.

Standard phones often get confused and connect to the wrong country's tower, triggering massive roaming fees (€10-15 per MB). Don't let this happen.
