I have a new phone and my existing IDMobile sim seems to partially works (I can use 4g etc and send/receive messages on WhatsApp and signal) but the actual phone number cannot make or receive calls or sms.  How can I get my phone number working again!?

Hi ​@dhfiej 

 

Thank you for getting in touch, and I am so sorry to hear of the issues that you are facing.

 

Please try the steps below, depending on the type of phone you have:

 

For Android:

  • Open Settings
  • Tap General Management
  • Tap Reset
  • Select Reset network settings

 

For iPhone:

  • Go to Settings
  • Tap Phone
  • Tap My Number
  • Delete the old number
  • Enter the new number
  • Tap Save

Then follow these steps to refresh iMessage:

  1. Go to Settings
  2. Tap Messages
  3. Turn iMessage OFF
  4. Go to Settings > General
  5. Tap Reset
  6. Choose Reset Network Settings
  7. Once your iPhone restarts, go back to Settings
  8. Tap Messages
  9. Turn iMessage ON again

Your iPhone should now recognise the new SIM and verify your number.

 

Regards,

Hi - thanks for a speedy help - I have done this, but it still doesn’t work. I have also been trying to connect with help via chat (and have followed all guidance about troubleshooting chat issues) but still can’t connect directly with your support team. Please help!
