Gmail error

Hi guys, I’ve bought 10 domains and wanted to buy 2 gmail per domain (according to what I’ve read/watched online) but impossible to verify the gmails because I used my phone number too many times
Same for all my family phones

I tried different softwares/ tools like quackr/ slynumber but nothing worked…

I’m from Europe btw, and want to pay is usd

Do you have any tips or recommendations?
How do you guys do it?

Thank you for your help!
