Bitcoin.se - Safello
Safello Support

Those who use Safello with their widget do not have the ability to send bitcoins
to an address that someone else owns or uses with them.

In order to resend, you must first send bitcoins to a wallet you own and then
to the address you wish to send to.

Conclusion: First create a wallet for bitcoin, download an app to your mobile,
for example

Coinbase Wallet
