Safe Talk allows you to generate a temporary phone number to use for 7 days to give to people you don’t trust/know. Each number costs 1.50 and you can choose to extend your usage of the number after seven days or cancel it. Avoiding confrontation seems very British-y, but this service should do well in the US for daters. It’s simple – text CALL to 80876 and get a temporary number that diverts to your mobile phone for seven days, and keep your own number safe.”]
