About Us
At PreferSIM, we believe staying connected while traveling the world shouldn't be complicated, expensive, or unreliable. We're a team of passionate travelers and tech enthusiasts who got tired of paying outrageous roaming fees, hunting for local SIM cards at airports, and dealing with throttled data when we needed it most — so we built something better.
Our Mission
Our mission is simple: give every traveler instant, reliable, and truly unlimited connectivity — anywhere in the world — without the hassle. No hidden fees. No throttling. No surprises on your bill when you get home.
What Makes PreferSIM Different
- Truly Unlimited Data — We mean it. No speed caps, no throttling after a certain threshold, no fine print. Stream, video call, and navigate freely.
- No Hidden Fees — The price you see is the price you pay. No activation fees, no roaming surcharges, no unexpected charges.
- Instant Activation — Your eSIM is delivered digitally the moment you purchase. No waiting for a physical SIM card in the mail.
- Wide Global Coverage — From the bustling streets of Tokyo to the remote landscapes of Patagonia, PreferSIM keeps you connected across 70+ countries and regions worldwide.
- Works on Your Existing Device — If your phone supports eSIM (most modern smartphones do), you're ready to go — no hardware changes needed.
