No Text Messages Rec’d

I have not been able to access my Google account for hours. I request the second of the 2-step verification — a text message, but never receive one. This morning I signed into Yahoo, and did not receive that text either. However, Yahoo, unlike Google, provides an option to call with the code. Yahoo called with the code and I got into my Yahoo account within a few minutes. I have yet to be able to access my Google account.
