A2P Questions Aren’t Always Easy to Answer. So, Ask Us.

Magic 8 Ball that reads 'Your Answer Awaits'

If you work in A2P messaging long enough, you get used to having questions.

Sometimes they’re straightforward:

Why was this 10DLC Campaign rejected?

Other times, they lead you down a rabbit hole:

Is this actually a carrier requirement? Who enforces it? Does it apply to my customers?

And increasingly, there’s an entirely new category:

What should we actually be doing about RCS?

The problem usually isn't a lack of information. There are carrier notices, provider documentation, industry announcements, FAQs, newsletters, API docs, webinars, support articles, and plenty of opinions floating around.

The harder part is figuring out which answer applies to your situation.

Welcome to A2P Messaging

A2P is an ecosystem involving mobile carriers, Direct Connect Aggregators (DCAs), messaging providers, registries, software platforms, businesses, and other parties—all with different roles in getting a message from Point A to Point B.

That can make seemingly simple questions surprisingly difficult to answer.

For example:

  • Why does a 10DLC Campaign keep getting rejected?
  • Should a particular use case use 10DLC, Toll-Free, Short Code, or RCS?
  • What information should an ISV collect from customers before submitting a registration?
  • Is this new 10DLC compliance requirement mandatory, and who is actually enforcing it?
  • How will a carrier fee increase affect messaging costs at scale?
  • What does it take to start offering RCS Business Messaging?
  • How should an ISV think about becoming a Campaign Service Provider (CSP)?
  • Is there a better way to structure an opt-in flow before submitting it for review?

Sometimes there is a simple answer. Sometimes the answer is everyone's favorite: it depends.

But even then, knowing what it depends on can save a lot of time.

Sometimes You Just Need to Ask Someone

We publish a lot of resources at Telgorithm about 10DLC, RCS, carrier fees, compliance changes, messaging APIs, registration, the 10DLC ecosystem, and the broader A2P ecosystem.

But we also know not every question warrants reading six articles, three carrier notices, and an API document.

Sometimes you just want to ask:

“Hey, what does this actually mean?”

So, we created a way to do that.

Ask Us Anything About A2P

Have an A2P question? Send it our way.

It can be about 10DLC, RCS, Toll-Free, compliance, registration, carrier fees, or messaging APIs. Or the oddly specific situation your team has been debating in Slack for the past week.

We'll put it in front of someone on the Telgorithm team who works with this stuff every day and get you an answer.

No sales call required, no strings attached.

And no crystal ball required, either.
