Free safe site for getting a 2nd phone number online

just looking for suggestions.
saw youmail.com but it looked mad sketchy.
any other suggestions

depends, you want it always with you or just to take sms? if something throwaway then sms24.me might help but if you want something to keep with you there is https://jmp.chat/

i would like something free

Phone numbers aren’t free. I suspect anything that is free is going to be sketchy.

MySudo is easy and relatively cheap if you aren’t looking for something that protects you from law enforcement / government.
