Where a second network earns its keep
One plan covers all of them.

Platforms and tunnels where one network gives up.

Games and concerts, when everyone is on the same towers.

Trails and back roads your carrier covers thinly.

The one room where calls over data always drop.
Then $18 / month. No contract. Taxes and fees shown at checkout.
How it works
Your phone can already run two lines at once. SecondBars is the second one.
A SecondBars eSIM is ready to be added to this iPhone. Your current line and number stay the same.
Add the eSIM
Check out, scan the QR code, tap Continue. It takes a few minutes and nothing about your current line changes.
Two lines, one phone
SecondBars sits next to your carrier. Calls and texts keep using your number.
Your phone will use cellular data from both lines depending on coverage and availability.
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.
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.
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.
Two networks beat one
When your carrier has no coverage, your phone has somewhere else to go for data instead of going offline.
