If you don’t want to transfer your existing number, you can call and say you’d like to test the network quality before committing to a plan. They’ll send you a prepaid sim with some credit on it. You can then call and say you’d like to sign up with this SIM card. Activation will become 0.– since you already have a SIM card and icing on the cake: the free credit leftover will be deducted from your next bill. I don’t think they’ll let you port your number with this method though.
