Stay Reachable Anywhere with Call Forwarding
Call forwarding allows you to redirect calls from your main phone number to your Second Phone number, so you can answer them directly in the Second Phone app.
This can be especially helpful while traveling, when cellular signal is weak, or when you want to keep work and personal calls more organized.
1. Reduce roaming costs while traveling
Before leaving for your trip, you can forward calls from your regular number to your Second Phone number. This allows incoming calls to ring inside the app instead of through your physical SIM card while abroad.
This is useful if you:
turn off your home SIM while traveling
want to stay reachable on your usual Canada or US number
want to reduce or avoid roaming charges for incoming calls
In many cases, setting up forwarding before leaving the country helps reduce roaming costs for incoming calls.
A few important things to keep in mind:
We recommend enabling forwarding before traveling, as some carriers may not allow forwarding changes while roaming.
Call forwarding only applies to voice calls. SMS messages will continue to be delivered to your original phone number.
Your carrier may apply standard forwarding charges depending on your mobile plan.
To receive calls in the app while abroad, you’ll need:
Wi-Fi
or mobile internet
Need internet during your trip? You can activate an eSIM in just a few minutes — no physical SIM card required.
2. Receive calls even in areas with weak signal
Cellular coverage may sometimes be weak indoors or in certain locations.
If you experience poor reception at home, at work, or while traveling, you can forward calls to your Second Phone number and answer them using Wi-Fi or mobile internet instead.
This can be especially useful if:
your office has poor reception
your building blocks mobile signal
your carrier performs poorly in your area
you live in a rural or remote location
Important:
Calls inside the app require Wi-Fi or mobile internet.
SMS messages are not forwarded.
3. Keep work and personal calls separate
Use one number for work and another for personal life — then forward calls into Second Phone Number when you want everything in one app.
This can be useful for:
freelance work
clients
side businesses
online marketplaces
travel
dating apps
It’s an easy way to stay organized without carrying two phones or constantly switching between devices.
Important:
Call forwarding only works for voice calls.
SMS messages continue going to the original number.
How to set it up
Step 1. Copy your Second Phone number
Open the Second Phone app and copy your number.
Use the number format required by your carrier.
Some carriers require:
a 10-digit number
or 1 + area code + phone number
Examples are listed below.
Step 2. Dial your carrier’s forwarding code
Open the regular Phone app on your main phone and enter the forwarding code exactly like making a normal call.
Then tap the green Call button.
You’ll usually hear:
a short confirmation tone
or a voice message confirming forwarding is active

Done using call forwarding?
To disable forwarding, simply dial your carrier’s turn-off code from the table above.
Everything goes back to normal instantly.
A few important things to know
Some prepaid or low-cost carriers may not support forwarding to VoIP numbers.
International forwarding can become expensive.
Forwarding calls from non-US or non-Canadian numbers to a US number may trigger international forwarding charges from your carrier.
If copy-pasting the code doesn’t work, type it manually. Some phones automatically add formatting that can break carrier codes.
