My friend had an iPhone 6 that was lost recently. The phone is offline now so we couldn't locate it using Find My Phone
She wants to recover the data from the iCloud account connected to the lost device. When she tried to login to the Online portal for iCloud, we were asked to enter a verification code that was being sent to the lost device. So she got a new sim card under the same number, put it in a new phone and tried the SMS option for the verification code. But it seems any sms that is being sent to the number is sent as an to the lost device and not as a normal sms. So we cannot get the verification code now.
Any other way to get the verification code or possibly change the phone number of the iCloud account without access to the device ?
Thanks in advance.
