Download 2ndSIM and get connected before your next trip.

eSIM FOR TRAVEL

Skip the airport SIM counter. Pick a plan, scan once, and your data is live.

Local plans for a single-country trip
Regional plans that follow you across borders
Global plans for multi-stop routes
Activation in minutes, no extra device and no physical SIM to swap
Real-time usage tracking, so you always know what's left
Clear pricing up front. No roaming surprises.

Flying soon? Set up your data plan tonight and arrive already online.

OTP AND VERIFICATION CODES

Receive one-time codes on a number that isn't your personal line — sign-ups, deliveries, banking, marketplaces. Your real number stays private, your main inbox stays clean, and codes arrive over Wi-Fi or mobile data wherever you are.

Get a number now and keep verifications in one place.

US AND CANADA NUMBERS

Choose a number from available regions in the United States and Canada. Handy for reaching contacts locally, registering on regional services, or keeping a familiar area code while you travel. Set one up in seconds, with no contract and no second phone to carry.

YOUR SECOND PHONE NUMBER

Call and text like a regular line, straight from the app.

Make and receive calls over Wi-Fi or mobile data
Send and receive SMS
Keep work, online listings, and daily communication separate from your personal number
Manage your number and your data plans side by side
