So I'm getting a new phone Friday (HTC Wildfire S, I've decided) and my GoPhone balance doesn't run out until the end of the month. I've compromised with my parents that if I got the phone, I'd wait until the end of the month to start the service (Which is $10 more than I'm paying on AT&T currently). So if I buy the phone, can I activate it/get a new phone number (Which I need because my current phone number isn't in this area code/it annoys me and my phone number has been spammed by numerous telemarketers) without topping up right away? Or do I have to put money on the account right away? If so, I can wait a week to activate it (I'll just play around with the phone itself until then!) Thanksya!
