If you need to verify your phone number when registering as a member on the seller's website, you can try using your personal phone number for verification in a location with good signal if the area code can be changed.
If you fail to receive the verification code or fail to change the area code, you may need a local phone number for verification. You can contact the seller's customer service for other verification methods.
You can also consider using "BUY&SHIP Proxy shopping" service if you cannot register in seller's website.
