Greek phone numbers

[Fvckcovid]

Hello all  i am newbie here .
I have 110 greek mobile sim cards only used in Google can anyone advise me how i can use them?
I see people selling sms verifications.
Because of covid i m unemployed at the moment so looking for an income.
If asking for the sim cards all are bought and are real.
I can do some verification for free or if any one wants cooperation on anything.
