Im with o2 mobile boradband,
I've had to have a replacement sim card.
My mum rang up to get it sorted out for me
but it wuouldnt connect me, we went up the shop
and they said we had to wait for the sim to activate,
how long would this usually take ?How long does it take for a replacement simcard to activate ?Normally, seconds.
Go back to the shop or give them a call back. Don't get off the phone until your cell phone is working.
