Blacklist check - Samsung

[Nimz]

Is there a way to check the IMEI status of a phone?

Situation:
Staff member bought a Samsung A20 Dual Sim phone from Cash Crusaders about a month back
Everything was working fine until today, it says SIM 1 not allowed so she thought it was the SIM that was faulty and did a SIM swap
issue still persists.

I advised her to try the same SIM in slot 2 and that works fine.

Want to rule out blacklisting before taking it back to Cash Crusaders or Samsung for the fault

I've tried the IMEI on international sites and it shows up as clean, i'm assuming that local networks use a different database

Some providers firmware block one of the SIM slots, Vodacom being one of them.. if the phone originated from such a provider, this is why the SIM slot doesn't work..

Hmm, I doubt Vodacom sell dual SIM phones. I know Cell C and Telkom do
