GoHighLevel A2P Verification Help

I need an A2P campaign verified and fully operational inside my Go High Level account. My priority is making sure the brand registration, campaign filing and phone number setup all meet current carrier requirements so messages reach U.S. mobiles without being blocked.

I keep getting failed due to
Opt in message via trust-center. Need help getting it approved and confirming the whole flow from my Wix site’s lead-capture forms through to successful text delivery.

Please tell me how quickly you can start and what information you will need from my side so we can get this verified without delays.
