Clarity please on Skype ending vs. continuing Skype number subscription international 2FA capabilities

I need unhindered text and voice call Two-Factor Authentication for U.S. websites, which my long-held annual subscription U.S. Skype number has always been easily able to do even though I am outside the U.S. I somehow don’t believe Skype when they say my subscription, auto-renewed just last month in February 2025, will continue without issue for the next 12 months. I need more clarity, as a message last week in my iPhone Skype app simply states that Skype will end in May 2025, which doesn’t inspire confidence.

Am I misunderstanding the connection between Skype closing in May 2025 versus what to concretely and realistically expect going forward for the next 12 months with my just-renewed annual Skype number subscription? I need unhindered international text and voice call Two-Factor Authentication and an accompanying U.S. phone number for this purpose, and didn’t think I’d have to sort out losing Skype capabilities in this regard for another 12 months.
