Hi @Sonia goldsbury,
We're really sorry to hear you've been experiencing this for so long. We completely understand how frustrating it must be not being able to make or receive calls.
If the iD Mobile app is continually logging you out, we'd recommend trying to log in through My Account on our website instead: https://my.idmobile.co.uk/login
If you're able to log in there, you can check your account and, if needed, contact our Customer Service team via Live Chat so they can continue investigating the issue with your service.
If you're still unable to access your account on the website, please let us know and we'll be happy to help further.
Regards,
Gemma M
The iD Mobile Social Media Team
