That's exactly where Adam Czarkowski, Product Manager, Collaboration, at TPx found himself when Mavenir pulled the plug:
- 12,000 users.
- Over 1,000 customers.
- A ticking clock that was about to destroy TPx’s entire SMS operation.
"Sabrhub definitely saved us," says Adam. "Our existing vendor was shutting us down in 60 days. So we found ContextSMS and the response was, 'Yeah, alright, we'll move you over.'”
So here's what happened when TPx found the right migration partner and compliance solution…
When a Forced Migration Threatened an SMS Business — ContextRegister Turned It Around
Tpx isn't a tiny startup with a handful of customers.
It’s been in the game for years, serving everyone from K-4 through K-12 schools to the New England Patriots🏈. Its SMS platform handles everything from plumbing companies sending service updates to legal offices coordinating with clients.
Life without SMS for these companies was not an option.
But when Mavenir decided to shut down its platform, the scale of the problem became clear:
- 12,000+ individual users who depended on SMS
- Over 1,000 companies across every vertical you can imagine
- 60 days to migrate everything without losing service
- Zero operational staff equipped to handle manual brand registrations
These numbers paint a clear picture. Unfortunately, it wasn’t a pretty one.

TPx did it in 30 days.
Here's where it gets interesting. Most SMS migrations of this scale take months of planning and armies of technical staff.
TPx completed theirs in just 30 days.
- Before ContextSMS: Stuck on a platform that was shutting down with no migration path
- During Migration: 12,000+ users moved seamlessly with zero service interruption
- Post Implementation: Full integration with TPx's Odin provisioning platform and in-house systems
TPx now uses ContextSMS and all its customers are free to send as many messages as they need and keep their own clients happy.
❌ Easy? Not even close.
Do you remember when 10DLC compliance enforcement hit in February 2025? Yeah, that was a fun time, wasn’t it?
How TPx Simplified 10DLC Compliance with ContextRegister
2025, compliance wasn’t top of mind. At the time, TPx had just four registered brands. Most customers — local service businesses like plumbers, clinics, and wellness centers had no idea what 10DLC even meant, and internal teams were suddenly buried under paperwork and regulatory confusion.
“Oh, it was a nightmare,” recalls Adam. “It just came out of the blue.”
That’s when TPx turned to ContextRegister. Within two months, the platform helped register 30–40 brands effortlessly — automating what used to take weeks. Today, TPx manages 70+ compliant brands with ease, all through a single automated dashboard.
The Manual Alternative Would Have Been Impossible
When asked to estimate the manual effort involved, Adam's answer was immediate:
"200 hours or more. It really saved us quite a bit. It would have been a nightmare if we didn't have ContextRegister.”
Think about that. 200+ hours of manual brand registration work that would have required:
- Understanding complex The Campaign Registry requirements for each business type
- Collecting 40+ fields of information per application
- Managing EIN validation and legal documentation
- Explaining compliance requirements to customers who "don't understand why they need this code snippet"
As Adam noted: "We do not have the operational staff to do that, so we definitely had to outsource it to Sabrhub."
The 10DLC Compliance Self-Service Platform Built for CSPs and Their Customers
The beauty of ContextRegister isn't just the automation, it might come as a surprise but it' s also how it makes compliance invisible to end customers.
"Registering with the campaign registry is not easy," Adam explains. "Most of our customers don't understand. Having an easy to understand platform has definitely been a benefit."
With ContextRegister, TPx eliminated confusion for its non-technical customers while keeping compliance fully managed in the background. The platform handles everything — from EIN validation to campaign approval including complex scenarios like:
- Franchise businesses that can’t implement compliance code snippets
- Monthly compliance validation for ongoing adherence
- Hosted opt-in forms for customers without technical resources
- Appeal processes when carriers block campaign traffic
For self-serve users, compliance is as simple as pasting one line of code into their website. For everyone else, Sabrhub takes care of the rest — hosting, validating, and managing compliance infrastructure end to end.
Setting the Stage for What’s Next in Business Messaging
ContextRegister is setting TPx up for long-term growth. We stand by that.
“We’re definitely looking to expand our SMS and MMS capabilities,” Adam says. “It sets us up for when we expand to MMS and Microsoft Teams.”
That means when TPx launches multimedia messaging or Teams-integrated SMS, no new migration will be needed. They’re already operating on the infrastructure that supports it.

Now what does it mean for other communication providers?
If you’re a CSP struggling with 10DLC compliance or managing platform migrations, TPx’s story is your wake-up call.
The manual approach doesn’t scale. It wastes hours, invites rejections, and leaves customers waiting — frustrated and unable to send texts when it matters most.
When compliance enforcement hit in February 2025, many providers saw message traffic blocked overnight. TPx didn’t.
Because they had ContextRegister.
What This Means for CSPs
ContextRegister turned what could have been a compliance crisis into a competitive advantage for TPx.
Results:
✅ 12,000 users migrated in just 30 days with zero service interruptions
✅ 4 → 70+ registered companies post-enforcement
✅ 200+ hours of manual work eliminated through automation
✅ Forced migration turned into an integrated, scalable infrastructure
If you're serious about offering SMS services at scale, the question isn't whether you need a solution like ContextRegister. The question is whether you can afford the 200+ hours of manual work when compliance enforcement hits your customers.
