If you found this page, you're probably weighing CallFire against InfinitySMS for your real estate outbound texting — prospecting, follow-ups, open house blasts, or investor campaigns. Both platforms can send SMS. The real differences come down to how they charge you, how they handle 10DLC compliance, and whether either one was actually built with real estate workflows in mind.
What Is CallFire, and Who Is It Built For?
CallFire is a general-purpose voice and SMS platform that serves a wide range of industries — political campaigns, nonprofits, retail, and more. Its pricing runs on a credit system: you buy a bundle of credits, each credit covers a certain number of SMS messages or call minutes depending on the tier. It's a flexible model if your usage is unpredictable or occasional, but it has a specific catch that hurts steady senders.
CallFire credits expire. If you buy a bundle in January and don't use it all, you don't roll those credits forward indefinitely. For real estate professionals with seasonal campaigns or irregular send volume, that means paying for credits you lose.
What Is InfinitySMS, and Who Is It Built For?
InfinitySMS is an SMS marketing platform built specifically for real estate — agents, teams, brokers, and investors. The pricing model is simple: $99/mo flat fee plus $0.02 per SMS send. No per-seat fees, no credit bundles, no expiry. Your credits never expire. If you send 1,000 messages one month and 5,000 the next, you pay exactly what you send at the same rate.
InfinitySMS also handles 10DLC registration as a managed service for real estate businesses. That matters because 10DLC — the carrier-level registration required to send application-to-person SMS in the US — is a meaningful compliance hurdle that many platforms leave you to figure out on your own.
How Do the Pricing Models Actually Compare?
The honest way to compare these two platforms is total cost at real send volumes, not just the base price. Here's how that math looks across common real estate outreach scenarios.
| Monthly Send Volume | CallFire (credit model, varies by tier) | InfinitySMS ($99 + $0.02/send) | Notes |
|---|---|---|---|
| 500 messages | Depends on credit tier purchased | $99 + $10 = $109/mo | Low-volume agents or single campaigns |
| 1,000 messages | Depends on credit tier purchased | $99 + $20 = $119/mo | Typical active agent follow-up cadence |
| 2,500 messages | Depends on credit tier purchased | $99 + $50 = $149/mo | Small team or consistent drip campaign |
| 5,000 messages | Depends on credit tier purchased | $99 + $100 = $199/mo | Active investor or multi-agent team |
| 10,000 messages | Depends on credit tier purchased | $99 + $200 = $299/mo | High-volume wholesaler or large team |
| Unused credits | May expire depending on plan | Never expire | Critical for seasonal campaigns |
CallFire does not publish a simple per-message rate independent of its credit tiers — actual cost per message shifts based on which bundle you buy. Always verify current CallFire pricing directly with their team before making a decision.
What About 10DLC Compliance for Real Estate?
10DLC (10-digit long code) registration is now required by US carriers for most business SMS. Without it, your messages get filtered or blocked. This isn't optional — it's table stakes for any outbound real estate texting program.
CallFire supports 10DLC registration, but it's not a managed service they've specifically built around real estate use cases. You're largely responsible for navigating the registration process yourself.
InfinitySMS handles 10DLC registration for real estate businesses as part of its managed service. If compliance setup is something you'd rather not own yourself, that's a practical difference worth weighing.
Where CallFire Has a Genuine Edge
This comparison wouldn't be honest without acknowledging where CallFire holds its own. CallFire is a mature platform with strong voice broadcast capabilities — if you're running a mixed voice + SMS outreach strategy, it's worth evaluating. It's also a reasonable fit if your SMS volume is very low and occasional, where a credit bundle might cover you cheaply without hitting expiry. And if your use case isn't specifically real estate — say you're a property management company with varied outreach needs — CallFire's general-purpose design gives you more flexibility across verticals.
Where InfinitySMS Has a Genuine Edge
- Flat per-message rate ($0.02) that never changes regardless of volume tier
- Credits never expire — no lost spend from seasonal slowdowns
- No per-seat fees — add agents to your team without the bill climbing
- 10DLC compliance handled as a managed service for real estate
- Purpose-built for real estate workflows: agents, investors, teams, and brokers
Which Platform Makes More Sense for Your Real Estate Business?
The right answer depends on your actual usage pattern. If you send SMS steadily throughout the month — prospecting, follow-up sequences, listing alerts — a flat per-send rate with no expiry is almost always more economical and easier to budget for than tiered credit bundles. If you send infrequently or in one-off bursts and want voice capabilities in the same tool, CallFire is worth a look.
For real estate teams and investors running consistent outbound campaigns, the math on InfinitySMS is straightforward: $99/mo + $0.02 per message, no credits to track, no expiry to worry about, and 10DLC handled for you.
Do InfinitySMS credits expire like CallFire credits?
No. InfinitySMS credits never expire. Whether you send heavily one month and go quiet the next, your remaining balance carries forward. CallFire credits may expire depending on the plan you purchase, which can result in losing spend during slower periods.
Does InfinitySMS handle 10DLC registration, or do I have to do it myself?
InfinitySMS manages 10DLC registration for real estate businesses as part of its service. This covers the carrier-level compliance required to send outbound SMS in the US without your messages being filtered. CallFire supports 10DLC but does not emphasize it as a managed real estate service.
If I add more agents to my team, does InfinitySMS charge per seat?
No. InfinitySMS does not charge per-seat fees. The flat $99/mo base rate covers your platform access regardless of how many agents or team members are using it. You only pay more when you send more messages, at $0.02 per send.
