mANTBox 19s not discoverable on mobile

i have mANTBox 19s
but not discoerable on mobiles i dont know why , i was have omnitik 5 ac and i can reach the WiFi without problems , on computers i saw it but on mobiles cant be

any advice :frowning: :frowning:

Do you use the same country settings and channel frequencies on the mANTbox like you did on the OmniTik? I could imagine that your phones could ignore some WiFi channels depending on their target market settings.
