Got hacked - should I get a new phone/number?

Hey guys,

Many thanks to Binance, I was able to reactivate my account thanks to the help of the Binance Support Team. 10/10 service and they were with me throughout the whole process.

- I use an Android phone currently
- My email was hacked into 3 days ago – and this is how my Binance account got hacked
- I'm not sure if the hacker accessed my email through my desktop and/or my phone
- After the hacking incident, I was able to secure my email using hardware 2FA and got rid of all devices linked to my email

I've done a full BitDefender scan on my phone and no Malware/virus was detected.

Do you think I'm being paranoid by switching to iPhone? And should I even consider changing my mobile phone number? Or is this not necessary?

Any advice would be greatly appreciated. Thanks.
