I would at this stage, get hold of a spare number and do this.

Add new number to amazon account

remove your auth device from amazon.


log out of amazon and log back in - do you then get an OTP text.


Tbh getting sms mesgages are insecure so i don't know why you are perusing enabling an insecure route...

On a side note do you have the amazon app on your phone as well?

@Taras,

I've tried different PAYG SIMS as part of my investigations - added to my Amazon account and OTP is fine. But for some reason once I added the temp number I couldn't remove it from my Amazon account- no option. The Amazon "James D" had to remove it.

I don't want to use SMS for my primary 2FA method. I want to add my mobile number to my account and have the option of SMS as a backup to my 3rd party authenticator app.

I don't have the Amazon apps installed. I prefer the browser. I could install to see if I receive a different outcome.

you can't delete it but just edit it to another number.... Semi stupid but there you go.

the app can do some authentication requests.


sidenote. when i go into the security bit for the number, amazon says its sent the code to my phone and email - my phone never gets that code, so something is up on the sms side

The problem has now been resolved.

I'd ordered from a 3rd party website and they used Amazon to fulfil the order. The order was delayed and I replied STOP to a one of the many "order delayed" messages from 65551 thinking it was the 3rd party but it was Amazon. I was charged £0.19p for the service by EE.

Numerous calls to Amazon and attempts to remove the block failed. Letters to Amazon HQ didn't appear to have an effect. Email CEO UK and after second attempt received a reply to say they would look into it.

Just logged on today and it allowed me to add my mobile to my account and sent me a OTP to verify the number.

Happy.

Glad you got this sorted
