Imessage not working with my phone number

[HA110]

Hi all

I travelled to USA in January and on my return but imessage associated with  my phone number stopped working.

I have spoken to apple several times, they have taken logs, and done all troubleshooting but cannot find a fault on there side. In addition when i put another sim into the device it is working so it points at the issue being with o2.

I've spoken to o2 several times but for some reason i keep being put through to tech support but the people are quite unhelpful and just keep blaming apple. It seems i cannot get through to tech support directly and must speak to someone inbetween who simply does not understand the issue.

Can anyone here help? or been through something similar?

FTR I have done factory reset, tried other handsets and my imessage works with email but just not with phone number. I have checked settings and have reset them several times to no avail. I have ordered a new sim and now gone onto esim as somone from o2 suggested that it could be the simcard. 

Someone please helpppp!

Thanks

@HA110 You can try O2 via social media in the morning:
Facebook (https://o2uk.co/O2CFB), Twitter (https://o2uk.co/O2CTW), or Instagram (https://o2uk.co/O2CIG)
Or you can call them on 0800 081 0255

The O2 online advisors are not available on Sundays. I will also tag @O2Lisa who will be on Monday morning.

Thanks @Bambino - I’m hoping to get a solution from here S I’ve tried Reaching out to o2 with little or no help with a solution. I’m hoping a community memeber went through a similar issue and Dan advise me on here.

thanks anyway!

@HA110 

The problem with iMessage is that is an Apple provided service, using Apple Infrastructure Apple Push Services and Issued certificates to register your number to be able to use the service, and there is very little o2 can do apart from check you have data and an send the registration text. 

All Apple will check is the handset and not the backend service..

Have you tried the details below:

1. Turn off iMessage. Go to Settings. Scroll down and tap on Messages. Switch off iMessage.
2. Turn off your phone. Wait 5-10 minutes, then turn it on again.
3. Go to Settings → Phone and make sure My Number is set correctly. Change it if it isn't.
4. Turn on iMessage again. Go to Settings → Messages and toggle iMessage on.

And these settings

1. Sign out of your Apple ID. Head to Settings → Messages → Send and receive, then tap your Apple ID email at the top and tap "Sign out".
2. Turn off iMessage. Head to Settings → Messages and toggle it off.
3. Restart your phone.
4. Turn iMessage back on. Go to Settings → Messages and toggle iMessage on.
5. Sign into your Apple ID. Head back to Settings → Messages → Send and receive, then tap "Use your Apple ID for iMessage".
6. Check your carrier settings are up to date. As a last ditch attempt, head to Settings → General → About. Just hang about on this screen for around 60 seconds. If an update to your carrier settings is available, you'll see a pop-up appear.
