Aren’t their numbers been used thousands of times so your accounts will be flagged the next second as potential spammers?
i use this one, Dual sim cardm, cheap & its battery last for 5days
Smspva is known by instagram by now. Using them will definitely lower your trust score imo
Almost all services for phone verification use the numbers more than once. Not thousands of times, but more than once can already be dangerous.
I usually use own sim cards. In the past I used 1 sim card to verify more than 1 account. My experience is that if 1 account got problems the other accounts that were verified with the same number also got problems. PV’s and worse.
If you care about your accounts you can buy sim cards. I believe there are some sellers on this forum. Another option is to use a service that gives you a dedicated number that you can use again and again for a fee. Services like smspva are only good for accounts you are not afraid to lose.
