I had issues with delayed codes before, but switching to a different country number on the same platform fixed it. Sometimes certain regions get overloaded or blocked by specific sites.
I’ve used it a few times and it worked fine for quick verifications. Sometimes you gotta wait a minute or two for the code, but it's still faster than dealing with SIM cards. Text messaging services like this are a simple way to register on platforms that require a phone number without using your personal one. Just make sure you choose the right country and app so it doesn't fail.
I usually grab their name from the site’s about page or LinkedIn, then personalize the intro by mentioning a specific post of theirs I actually liked—makes a big difference in replies.
I tried it a few weeks ago, and indexing worked pretty fast for me, way quicker than usual methods. If you're combining it with crowd marketing, the boost can be noticeable since your links already have user activity around them. Makes Google pick them up faster, at least in my case. Just avoid spamming your links everywhere—it still needs to look natural.
