Have u checked FireBase? They have amazing backend services such as wut u just mentioned

FireBase
isnt that a service by google? can i generate a phone number to recive sms with that?
Twilio has APIs for this very purpose.
so i can generate new phones by code and then receive sms ? i was checking out twilio but they just gave me a single number
If you want to go old school and save money by not using a 3rd party gateway, such as Twillio, you can always “text” your phone using SMTP (E-mail).
Most cell carriers allow you to send email directly to a phone as a text message, by appending the carriers gateway domain to the phone number. Just set the text you want sent as the body of the email, and plug the “Fully Qualified Number” into the “To” line like: [email protected] and send.

Rule 2- No malicious, intentionally harmful, or piracy-related software
No service will allow you to automate creation of accounts to bypass spam filters. That is against the terms of service of almost every account provider (and phone API).
