For the last few weeks I've been unable to make calls to other mobile phones. I can ring landlines and send texts but every time I try to call another mobile I get a "sorry the system is busy try again later" message. I've even replaced the sim card with a new one, but I still can't call other mobiles. Anyone got any ideas?
Hi @zzzzak welcome to the community and thanks for posting, I'm really sorry to see you're having problems making calls on your BT mobile service.
This sounds like it may be a fault with your BT Mobile account, I'd recommend you report it to the Mobile technical team. They may need to refer it to specialists to fix it, post back and let me know how you get on.
