As I understood, you are from another country and do not know how to register on the British site? I think in this case, only using a https://sms4you.net/free/ will help you. Temporary or fake numbers that are in no way linked to you can end the SMS and sales calls you get from online companies. You can get the disposable numbers for free on SMS4You to maintain a high level of privacy and anonymity. With the numbers, online companies can’t track what you do online, and scammers won’t be able to contact you directly with your phone number.
