step1: open the website : https://developer.arm.com/downloads/view/DS000B
step 2: click to log in
step 3: fill in the account password, then choose "SMS text message" to receive the comfirmation.
And then there is the error: The phone number is automatically filled in an invalid number, like this:
We have the following number on record for you. We will send a code via SMS to authenticate you.
Hi wang si , we will need to manually change the phone number. Please may you raise a support case through https://services.arm.com/support/s/contactsupport to do this. Hope this makes sense. Thank you.
