Looking for SMS provider

Hey
I have Crypto landing page and I want to send SMS to peoples who complete the form.

I am looking for sms provider
my end goal is to verify the phone so its be better if you have OTP solution,
If its only SMS's its ok also i could build my own OTP system.

thanks!

P.S send me a private message not only reply here beacuse I have new account here and i cannot reply to this post.

Not applying for the job.

If you want to build a OTP system for your website you may choose API’s.

The API will allows you to receive the SMS code and verify the account/number.

Furthermore you can use Python to create your OTP , is kinda easier to link API & OTP
