SMS Gateway - how to use it correctly?

Question

SMS

There is a task to send sms through php.
As I understand it, I need an SMS Gateway service.
What can you advise?
And the difficulty lies in the fact that the system will be used in Switzerland, but do I need a Ukrainian SMS Gateway for testing?
And are there any free proven services or methods?
Thanks for any help!
