smarty data sim with unlocked 3 router

hi,

i got a 40gb smarty data sim and bought an unlocked zte u50 5g router (its branded 3)

i put the sim in the router and it automatically connected  and set the apn to 3internet and its working fine.

do i need to reconfigue the apn to the smarty one? (mob.asm.net)

or should i just keep it as it is.

many thanks
