Unable to recieve calls apart from 3 network

[Nicola1]

I've had the same number for around 15 years no problem, as of this morning I am unable to recieve any updates calls from other networks and landlines, after 3 hours on chat, a visit to the three store and on call to another person they've now said they will escalate the issue to within 48 hours, any suggestions please. I've done all of the usual things. Thanks

@Nicola1are you saying that you ported your number to Three? or are you saying that you have been with Three for 15 years and this morning you started having problems?

[Nicola1]

I've been with three around 8 years I think I was with tmobile before that but this is the first time it's happened today 🙄 😂

if this was the first in 8 years you are lucky... all of us here in the users forum have a fair share of occasions that we can moan about it

Because you contacted support over chat, I'd assume they check the status of the network for your post code (you can check here https://www.three.co.uk/support/network-and-coverage/coverage?tab=2 )

Do you still have the problem? Or what is not working: data? calls? sms?

[Nicola1]

Yeah they checked all of that even though I had already done the obvious 😂 I can make calls, send texts, use Internet etc just unable to recieve calls from certain networks and landlines
