How to set up your wallet on a 2nd device
As long as you have written down your 12 word backup phrase, which was shown when you first opened the Bitcoin.com Wallet app, you will be able to restore your wallet to your second device using that same phrase. If you did not write it down, you should do so now by going to Settings > Your Wallet > Backup.
Please note that you will need to do this for each sub-wallet inside your Bitcoin.com wallet if there is more than one (i.e. if you have one or more Bitcoin sub-wallets, and Bitcoin Cash sub-wallets).
To set up the same wallet on 2 different devices (phone/laptop) please follow the instructions below:
When you have downloaded the Bitcoin.com wallet on your 2nd device, tap on the "+" symbol to the right of your bitcoin wallets.
Now select Import wallet
Enter your 12 word backup phrase for the wallet you want to import (BTC or BCH) and make sure you select the correct coin below.
There is also an option to scan a backup QR code.
Once you have entered the backup phrase and selected the correct coin tap on Import
You will now have the same wallet with the same backup phrase on both devices.
