@Tatsuhiko if you already tried different IPs like Draven suggested and it still fails, the platform is probably blocking VOIP numbers. most sms api providers use virtual numbers and those are dead for registration on main platforms now. you need to find a supplier that offers physical sim cards/non-voip numbers. what service are you trying to register anyway?

Just try another provider. The verification blocks some numbers and virtual services.

this is likely cause by device and number quality, make sure the IP is not blacklisted and use non-voip phone number.

clearing the profile usually isnt enough if they are tracking canvas or tls fingerprints. you need a proper antidetect and honestly, even physical sims get blocked if you use cheap residential proxies. mobile 4g/5g proxies are way better for this because the ips are shared with real users so they rarely block them. what platform is this for? some of them block almost all virtual sms providers instantly now.

also check whether the number range is already cooked... a lot of providers sell “real” numbers but the prefix has been abused to death, so it trips instantly even if the sim is legit. if you keep retrying the same service on the same range, it usually just gets worse, i’d leave it for a bit and test with a fresh carrier range instead of another number from the same pool.

another thing to look at is whether the country of your proxy matches the country of the number. if you're using a us number on a proxy from somewhere else, it's an instant flag on most strict platforms now. also don't go straight to the signup page on a fresh profile... warm it up for a bit, browse some random sites, accept cookies, then try. if the profile has zero history they hit you with the hardest verification filters right away.
