Went thru 2hrs of reading, can't find any info in Hotlink app about porting in(can't sign in also, as they needed me to have a hotlink no). just to be sure the ways of porting to prepaid pantas. rn, im on XOX mobile. I need a plan just for validity. so is this what i should do?

1. send a port out request to xox
2. buy a hotlink prepaid card(where can i get it)?
3. port in to hotlink?

or shall i buy the hotlink prepaid card first, before porting out XOX?

i was in hotlink website, but when i entered my XOX mobile no, it says invalid. Then, i went to Whatsapp support, & got stuck at the system sending me TAC, that i've nvr received. I restarted my phone, restarted the whatsapp process, but still no receive any SMS TAC
