Trying to change m sim card. but when i type in the sim card number, it says its invalid or already in use. i bought it less than 2 hours ago. and yes, ive triple checked that the number is correct. help?
Are you sure you purchased the proper card, prepaid if your a prepaid customer or postpaid if your a postpaid customer?
Also it can take some time for the SIM Card to become active after activating it online so pull your battery (or turn off the device if there's no removable battery) and sim Card for a minute or so then replace them and try the phone again as the card may already be activated but not active yet on the network.
