Stay Connected Anywhere Without Roaming Fees
When you travel abroad, staying connected can be expensive and complicated. Roaming fees, SIM swapping, or losing access to your main number can cause serious inconvenience.
What if you could travel anywhere — use a local SIM for cheap data — and still receive all your calls and SMS from your home number, instantly and for free?
Introducing 1SimBox, the world’s first no-roaming SIM box that keeps your number active and reachable, no matter where you go.
What Is 1SimBox?
1SimBox is a smart device that lets you use your home SIM card anywhere in the world — without paying roaming fees.
You simply insert your SIM card into the 1SimBox device before traveling. The box stays at home (connected to your Wi-Fi), while all your calls and SMS are forwarded securely to your smartphone through the 1SimBox App.
You can answer calls, send and receive texts, and even make outbound calls showing your real number — all through data or Wi-Fi.
It’s like carrying your SIM with you virtually, without the physical card or roaming costs.
How 1SimBox Works
1SimBox combines smart hardware with cloud-based telecom technology. Here’s how simple it is:
-
Insert Your SIM
Place your SIM card into the 1SimBox device and connect it to your Wi-Fi. -
Download the App
Install the 1SimBox app on your phone and log in. -
Connect Globally
From anywhere in the world, your app stays synced with your SIM.
All calls and SMS to your home number are instantly delivered via the internet.
That’s it. No roaming setup, no forwarding service, and no surprises on your bill.
Why Travelers Love 1SimBox
🛰️ Zero Roaming Fees
Stop wasting money on international roaming. 1SimBox forwards all your calls and messages over data or Wi-Fi, saving you hundreds of dollars on every trip.
🌍 Stay Reachable on Your Real Number
Receive calls and OTPs from banks, work, and family on your original number, even when using a local eSIM or foreign SIM for data.
📱 Works with Any Carrier
Whether your SIM is from AT&T, Rogers, Vodafone, or any local carrier, 1SimBox supports it all. Just insert, connect, and go.
💬 Supports Both Calls and SMS
Unlike many internet-based solutions that handle only text, 1SimBox provides full call and message functionality, including voice calling with your original caller ID.
🔐 Secure and Private
Your SIM card stays safely in your home country, inside your 1SimBox. All data between the box and your app is end-to-end encrypted, ensuring total privacy.
🧳 Perfect for Travelers, Expats, and Businesses
From digital nomads to business travelers, 1SimBox helps anyone who needs to maintain access to their home number — without switching SIMs or carrying multiple phones.
Example: Travel Without Losing Connectivity
Imagine John, a professional who lives in Canada but travels to Asia for meetings.
John’s Canadian SIM receives important client calls and banking OTPs. Normally, he’d pay steep roaming fees or switch SIMs and lose access to his number.
With 1SimBox, John simply places his Canadian SIM into the device before he leaves. In Japan, he connects his phone to Wi-Fi, opens the 1SimBox app, and instantly receives calls and messages from his Canadian number — just as if he were at home.
No roaming fees. No missed calls. No headaches.
