I also was not able to login to my Pay Pal account as I do not have a mobile phone so could not give a mobile number. After many tries I finally was able to speak to someone in Customer Service who arranged for me to login using my landline phone number rather than a mobile phone number. Now when the screen comes up and says to "Add Mobile Number", just below this it says "Not now" so I click on the "Not now" and am able to access my PayPal account. Hope this works for you.
