Open settings, select apps, scroll down and select phone, and where it says “My number” type your number starting with a 0(zero). Then click save.

Dear Paul,

My sincere thanks for your reply. After trying everything else, I was rather tearing my hair out.

Your suggestion fixed it - thank you - very much appreciated.

Best wishes

Hi I have had the same issue for days. I took the above action and I can now ring out but when people call me it rings  on their phone but does not ring on mine or show as missed call.

Is there anything else I can do please? 

Hi @AG24,

Welcome to the Community!

Have you tried enabling VoLTE on your handset?

As 3G is turned off you’ll need to enable VoLTE to make calls over 4G.

No it didn’t. I moved to O2 instead and it works fine now. 

Have had the same problem. But on my Samsung s10e I don't have the final "My number" option. Any idea where I can find it?

I've also tried all the various options, including waiting for over an hour for customer service before I gave up. Not impressed.

I'm relying on my mobile at the moment and having no calls is a BIG problem. Is there a way I can get out of my contract early? 

Hi @AG24 

Glad to hear you found a resolution that works best for you, we wish you the best with your new provider.

Hi @CathB 

The “My Number” options would be for iPhones, not Androids.

We’d recommend the below;

Hi @CathB 

Have you checked the coverage for VoLTE (4G) network in your area? https://www.idmobile.co.uk/help-and-advice/coverage

Do you see ‘LTE’ under the Network settings i.e LTE/3G/2G (auto connect)?
Is there toggle a under Settings > Connections > Mobile networks to turn VoLTE on and off?
With a SG phone you will need to see ‘LTE’ (NOT 4G) to be able to connect to the network.

Hi @Tom , I managed to get somewhere-see another thread.

Evidently I have a us-style handset so that's tough as far as iD are concerned and I should get another one. Which won't be happening, so I moved to a proper implementation on VoLTE with another provider, and its all good. 

Thanks

Hi @CathB 

Glad to hear you found the root of the issue, we wish you the best of luck with your new provider.

Ive been struggling for 3 weeks without being able to make or receive calls. Nobody in Curry’s could fix it and it’s been driving me crazy. Following your instructions it worked straight away and I am indebted to you. Thank you so much 

I can't make calls and receive calls 

@Jaffer Khaliq -

Have you tried all of these steps?

Thanks.
