Two lines, one phone

SecondBars sits next to your carrier. Calls and texts keep using your number.

Allow Cellular Data Switching

Your phone will use cellular data from both lines depending on coverage and availability.

03

Auto-switch in dead zones

Turn on data switching once. When your carrier loses coverage, your phone moves data to SecondBars by itself.

Why SecondBars

  • A second network

    A separate line on your phone, already installed when your main one drops.

  • Nothing to switch

    Your carrier, plan and number stay exactly as they are.

  • From 3 GB to Unlimited

    Pick the data you want each month, for maps, messages and calls over data.

  • Set up in minutes

    Scan a QR code after checkout. No store visit, no SIM in the mail.

  • Switches by itself

    Turn on data switching once and your phone moves data when coverage is lost.

  • Cancel anytime

    One plan, month to month, no contract.

Simpler

Add a line, change nothing

SecondBars is an eSIM that sits beside the SIM you already have. There is no port, no new number and no call to your carrier.

Faster

Live before your next dead zone

Buy it now and install it over Wi-Fi in a few minutes, so the backup is there the next time your bars are not.

Steadier

Two networks beat one

When your carrier has no coverage, your phone has somewhere else to go for data instead of going offline.

A second set of bars, 10% off to start.

Use the code SECOND10 on your first month. Plans from $16.20 now, $18 a month after, cancel anytime.
