How to find Mobile Phone number in order to recharge 4GX Dongle

How do I find my mobile phone number attached to my 4GX dongle - so that I can recharge it.

I do not have the email sent originally to activate the dongle but am out of credit and need to recharge.

Hi HelpMe29,


Your Pre-Paid mobile broadband service should be showing in your My Telstra App or in Telstra My Account online using:


Note: if it's been more than 6 months since the expiry date of your last recharge then the SIM has been automatically deactivated and you'll need to purchase a new SIM.


You could try taking the SIM out of the dongle, and putting it into a mobile phone (if it's the correct size SIM for the mobile phone) and dial #150# into the mobile phone and press the call button. This will then show the Pre-Paid SIM'S phone number and Account number.


You could also go to a Telstra store (if you have 1 nearby) with some ID to prove you own the Pre-Paid service and they'll be able to tell you what the number is and put a recharge on for you.


If you can't get to a Telstra store then you can send a message via the My Telstra App (blue icon in the Get Help section, bottom right of the screen). If Codi the bot replies with an irrelevant response type "I want to speak to a consultant". You'll be placed in a queue for a Telstra Employee to reply to your message. It could take hours for the initial reply to your message. You'll receive a notification on your mobile phone when they reply. 

I am NOT a Telstra employee and never have been. However, I AM a customer who volunteer's my time in the hope to help someone with their question.
