How long do I have to wait to make a call after doing a SIM Card Transfer?

[Monimoe]

When you transfer from another carrier with your new Sim Card, how long does it take to make a call out?

I believe sometimes simply swapping the SIM card will not activate service. You may need to contact the carrier to have them do provisioning on their end.

Yes I have done that, the new carrier said I am good to go to make a call just not receive calls right away.

Just found out when the other carrier activates your phone, you need to call from someone else's phone to activate yours. Well good to know, been trying to figure this out all night.
