Hi, I would like to recommend using a service that I use as well. They provide temporary numbers that you can use to confirm your PayPal account and it's paypal phone number just pick a number from the list on their website and you can get the necessary SMS to complete the registration.

Hi, I also used to use a disposable number for my own purposes and I can say that it's a great option because this way you leave your data safe and sure that you won't get a lot of unknown calls
