Textr does one job well: it gives you a second phone number on your existing device so your work texts and calls don't bleed into your personal life. For a freelancer, a solo consultant, or a one-person shop that mostly replies to inbound, that's often all you need — and you should not over-buy.
But "second number" and "SMS platform built to send at volume" are two different products, and the gap between them is where a lot of buyers get stuck. If you've started running campaigns, chasing leads with a dialer, or worrying about whether your texts are even landing, you've probably outgrown the second-number category. That's the comparison this post is about.
Full disclosure: I work for ReadySMS. I'll keep the Textr description in verifiable, general terms — their plans and features change, so confirm specifics at textr.team before you decide. My goal here isn't to dunk on a perfectly fine app; it's to tell you honestly where each one fits.
Where Textr is genuinely the right call
Textr sits in the "virtual second line" category — apps that give you a dedicated business number you can text and call from without carrying two phones. That category is real and useful. If your situation looks like this, Textr (or a similar second-number app) is probably the cheaper, simpler choice:
- You mostly reply to inbound texts and calls rather than blasting outbound.
- You want a clean separation between work and personal, and a number that survives if you change carriers.
- Your monthly send volume is low and conversational — dozens of messages, not thousands.
- You don't need to register an A2P 10DLC campaign because you're not doing application-to-person marketing.
If that's you, stop reading and go get a second number. Genuinely. The rest of this post is for people whose needs have grown past that.
The two things second-number apps quietly don't do well
There are two moments where a second-number app starts feeling like the wrong tool.
1. You want to send the same message to a lot of people. A second number is built for one-to-one conversation. The moment you try to text 800 contacts about an event or a promo, you hit two walls: there's no real campaign tooling, and carriers start filtering your messages because the number isn't registered for A2P traffic.
2. You want to call through a list, not dial one number at a time. Outbound sales and follow-up live or die on call volume. Manually dialing from a softphone caps you well under what a real power dialer does. Second-number apps generally aren't built for that workflow at all.
Those two gaps — bulk SMS that actually delivers, and a dialer that moves through a list — are exactly what ReadySMS is built around.
What ReadySMS adds on top of "a number"
ReadySMS is a sending platform, not a phone replacement. The point of difference:
- Registered A2P 10DLC, handled in-app. Brand and campaign registration happen inside ReadySMS — roughly ~$10/mo per brand and ~$20/mo per campaign in carrier fees, with approval usually in 1–3 days. Registered traffic is what keeps your bulk messages from getting carrier-filtered. We walk through the whole thing in What is 10DLC.
- Bulk campaigns and a two-way inbox. Send a blast, then catch every reply in a conversations inbox — without losing the one-to-one feel that made texting work in the first place.
- A built-in power dialer. Outbound voice with queue dialing, call recording, voicemail drop, and speed-to-lead auto-dial on new leads. So the same platform that sends your text can also work your call list.
- Native GoHighLevel integration. If you run on GHL, ReadySMS syncs inbound and outbound two-way, mapped per sub-account. (More on that in the GHL SMS setup guide.)
- Compliance scaffolding — automatic STOP handling, quiet-hours enforcement, and optional litigator/DNC scrubbing. None of this makes you lawsuit-proof, but it reduces the obvious exposure.
- 20 free test sends plus a $25 credit when you submit 10DLC registration, so you can pressure-test it before spending real money — pay-as-you-go, no monthly platform fee.
Side-by-side: which tool for which job
| Need | Second-number app (Textr) | ReadySMS |
|---|---|---|
| Dedicated business number | Yes — core feature | Yes |
| One-to-one texting/calling | Strong | Yes |
| Bulk SMS campaigns | Limited / not the focus | Built-in |
| Registered A2P 10DLC handled for you | Confirm at their site | Yes, in-app |
| Power dialer for call lists | No | Yes, built-in |
| Native GoHighLevel sync | Confirm at their site | Yes, OAuth two-way |
| STOP / quiet-hours / DNC tooling | Confirm at their site | Yes |
| Free to start | Confirm at their site | 20 free test sends + $25 credit on 10DLC registration |
This isn't "ReadySMS wins every row." If you only need the first two rows, the simpler app wins on simplicity. The table just shows where the line is.
The cost math when you actually send at volume
Per-message pricing only matters once you're sending real volume, so here's the worked version.
ReadySMS bills per outbound segment plus a flat, separately itemized $0.0045/segment carrier pass-through. On the Starter tier (0–50,000/mo) that's $0.0155 + $0.0045 = $0.0200 all-in per segment. As volume climbs the per-segment rate drops — Growth (50K–500K/mo) is $0.0125, and Enterprise (500K+/mo) is $0.0028.
Say you send a 175-character promo. That's over the 160-character single-segment limit, so it splits into two segments of 153 each. Blast it to 5,000 contacts on Starter:
5,000 contacts × 2 segments × $0.0129 = $129.00
Drop the message under 160 characters and it's one segment:
5,000 × 1 × $0.0129 = $64.50
That second number — message length — is the lever most people ignore. Add a single emoji and the per-segment limit collapses to 70 characters, which can double or triple your segment count. We get into all of that in how to reduce SMS costs, and you can model your own numbers on the cost calculator.
The honest caveat: a second-number app usually bills a flat monthly subscription, which can be cheaper if you barely send anything. Per-segment pricing wins when volume is real. Match the model to your usage, not to a sales page.
On the dialer side
If outbound calling is part of your motion, the Power Dialer is where ReadySMS stops looking like a Textr alternative and starts looking like a sales tool:
- Free — $0/mo, 1 agent, 1 number, 500 minutes/mo, then $0.06/min.
- Pro — $29/agent/mo, up to 3 agents, $0.05/min.
- Team — $69/agent/mo, unlimited agents, $0.0375/min, plus speed-to-lead auto-dial and manager monitoring.
The speed-to-lead piece is the underrated one: a new lead comes in, ReadySMS fires an instant text and queues an auto-dial. Getting a human on the phone inside the first few minutes is the single biggest lever on contact rates. If calling is your main workflow, the PhoneBurner alternative and OpenPhone alternative posts go deeper on that comparison.
So which should you pick?
Here's the decision in plain terms:
- Stay on a second-number app if you mostly reply to inbound, send conversationally, and value one simple monthly bill over campaign features.
- Move to ReadySMS if you've started running bulk campaigns, need registered 10DLC so your texts actually land, want a power dialer in the same place, or run on GoHighLevel.
A lot of people start on a second number, then quietly outgrow it the week they try to text their whole list and watch half the messages disappear into carrier filtering. If that's the wall you're hitting, the 20 free test sends (and the $25 credit when you submit 10DLC registration) are there to test whether the registered-A2P approach fixes it for you. Look at the full pricing first so the per-segment model is clear before you send a single message.
Right tool, right job. Sometimes that's a second number. Sometimes it's a sending platform. The trick is knowing which problem you actually have.
