Smrtphone and InfinitySMS solve different problems. Smrtphone is a calling and texting app built to live inside CRMs like Follow Up Boss and LionDesk — voice is the centerpiece, and SMS comes along with it. InfinitySMS is a dedicated SMS platform built specifically for real estate professionals who run SMS as a primary lead-gen channel. Choosing between them comes down to one question: are you paying for a dialer that also texts, or for a texting platform that your whole team shares?
What Is Smrtphone Built For?
Smrtphone is designed for agents and teams who want their phone calls and texts to flow directly into their CRM — Follow Up Boss and LionDesk integrations are the headline feature. Every agent gets their own line, call recording, and texting capability in one app. That's a real convenience if dialing is part of your daily routine and you want activity logged automatically.
The pricing model is per seat, meaning each agent on your team pays separately. SMS is included in the bundle, but so is the dialer — you're paying for both regardless of how much you actually use each one. 10DLC registration (the carrier compliance requirement for business texting) is something you manage yourself.
What Is InfinitySMS Built For?
InfinitySMS is a dedicated SMS marketing platform built for real estate — agents, investor teams, brokers, and wholesalers who send a meaningful volume of texts for lead generation. The pricing is a flat $99/month for the account, plus $0.02 per message sent. There are no per-seat fees, so a team of five agents costs the same as a solo operator at the account level. Credits don't expire.
10DLC compliance — the registration process that carriers now require for business SMS — is handled for you. You don't have to navigate brand registration or campaign approval on your own.
How Do the Costs Actually Compare?
The honest way to compare these two platforms is at volume, not at the base price. Smrtphone's per-seat structure means your monthly cost scales with headcount. InfinitySMS's flat account fee means your cost scales with messages sent, not with people. Here's how that plays out across a few realistic scenarios:
| Scenario | Smrtphone Est. Cost* | InfinitySMS Cost | Notes |
|---|---|---|---|
| Solo agent, 500 sends/mo | Per-seat fee (1 seat) | $99 + $10 = $109/mo | Smrtphone seat covers voice + SMS; InfinitySMS SMS only |
| 3-agent team, 2,000 sends/mo | Per-seat fee × 3 seats | $99 + $40 = $139/mo | InfinitySMS has no per-seat charge regardless of team size |
| 5-agent team, 5,000 sends/mo | Per-seat fee × 5 seats | $99 + $100 = $199/mo | Cost gap widens as headcount grows on per-seat platforms |
| 10-agent team, 10,000 sends/mo | Per-seat fee × 10 seats | $99 + $200 = $299/mo | InfinitySMS flat fee means no incremental cost per added agent |
*Smrtphone pricing is per-seat/per-user. Exact seat pricing is published on their website. The point is structural: every agent you add increases your monthly bill on Smrtphone regardless of SMS volume. On InfinitySMS, adding a team member costs $0 extra.
What About 10DLC Compliance?
10DLC is the carrier registration system that governs business text messaging in the US. If you're sending any volume of outbound SMS for lead generation, you need to be registered — unregistered traffic gets filtered or blocked by carriers. This isn't optional and it's not going away.
With Smrtphone, managing 10DLC registration is on you. That means understanding brand registration, campaign use-case selection, and carrier approval timelines — a process that trips up a lot of agents who just want to send texts.
InfinitySMS handles 10DLC registration for you. It's part of the service. You're not left figuring out carrier compliance on your own.

When Does Smrtphone Make More Sense?
If your agents are on the phone every day and you need call recordings, click-to-dial from Follow Up Boss or LionDesk, and automatic activity logging — Smrtphone is purpose-built for that workflow. The per-seat cost makes sense when every agent is using the dialer regularly, because you're getting a full phone system, not just texting.
It's a reasonable choice for teams where voice calls are the primary touchpoint and SMS is secondary.
When Does InfinitySMS Make More Sense?
If SMS is your main lead-gen channel — drip campaigns, new listing alerts, open house follow-ups, investor outreach — then paying a per-seat fee for a voice bundle you're not fully using inflates your cost-per-message unnecessarily. InfinitySMS's flat account fee means the math gets better as your team grows, not worse.
For brokers, investor teams, and high-volume agents who measure success in response rates and conversations started per dollar spent, a dedicated SMS platform at $0.02/send with no seat fees is a straightforward fit.
Does InfinitySMS integrate with Follow Up Boss or LionDesk like Smrtphone does?
Smrtphone's deep CRM embedding — where calls and texts log automatically inside Follow Up Boss or LionDesk — is a core differentiator for that product. InfinitySMS is a dedicated SMS platform; check our integrations page for current CRM connections. If seamless dialer-to-CRM logging is your top priority, that's a genuine reason to weigh Smrtphone. If SMS volume and cost-per-message matter more, InfinitySMS is worth the comparison.
Why does per-seat pricing matter if my team is small?
For a solo agent, per-seat pricing may not be a major factor. Where it becomes significant is team growth: every agent you add to a per-seat platform increases your monthly cost by one seat, regardless of how many messages that agent sends. On InfinitySMS, your account fee stays at $99/mo no matter how many agents you add — you only pay more as message volume increases.
What is 10DLC and why does 'done for you' matter?
10DLC (10-digit long code) is the carrier registration system that governs business SMS in the US. Without proper registration, outbound texts can be filtered or blocked before they reach leads. Navigating brand registration, campaign use-case filings, and carrier approvals is a real administrative burden. InfinitySMS handles this process for you as part of the service, so you don't have to become an expert in carrier compliance just to send text messages.
