Quo (OpenPhone) alternative for business texting, dialing and API

Quo, the product formerly called OpenPhone, is a good business phone system. It gives each teammate a number, a shared inbox, calling and texting on desktop and mobile, and it is billed per user. If your team mostly talks to customers one at a time, there is a good chance you don't need to switch.

This post is for the teams whose volume has outgrown that model: more outbound texting, campaigns to thousands of opted-in contacts, an app that needs to send through an API, or a software product that texts on behalf of its own customers. We make Ready, so we're biased. We'll be specific about where Ready fits, where it doesn't, and what we don't do. That includes power dialing.

The real difference is the pricing model

Quo charges per seat. Ready charges per segment. That is the whole comparison, and it decides which tool fits you.

• Per-seat pricing tracks headcount. Five people texting and calling all day cost the same each month whether they send 500 texts or 15,000, within the plan's limits. It is predictable, and it suits a team that works one conversation at a time.
• Per-segment pricing tracks volume. On Ready, every segment sent or received is $0.0075 on Standard, plus a $0.0045 carrier fee. There are no seats, so adding a teammate costs nothing. Sending more costs more.

We won't quote Quo's prices here, so check their current plans. The rule of thumb: if a few people send heavy outbound volume, per-segment usually works out better. If many people each send a light load of one-to-one texts, per-seat is often the better deal.

What each tool is built for

Dialing: what Ready does and doesn't do

Many people searching for a Quo alternative want automatic list dialing, so here is the plain answer: Ready does not auto-dial. There's no queue dialing, no parallel dialing, no voicemail drop and no call transfer. If calling through a list of 300 leads an hour is your main workflow, look at a dedicated dialer.

The Ready Dialer covers calling that happens alongside texting:

• Click-to-call from the dial pad in the dashboard or inside GoHighLevel
• Call recording and transcripts, with consent
• Inbound calls that ring the open pad, plus a Missed call card in the Inbox thread for each call you miss
• $0.025 per minute. Each started minute bills as a full minute. There are no seat plans, and every minute bills at that same rate.
• Only answered time is billed. A ring-out or a busy signal costs nothing. A call that reaches voicemail counts as answered and bills normally.

This setup works well when you text a new lead immediately and then call from the pad while they're still engaged.

Texting at volume: segments, throughput and 10DLC

Heavier outbound volume hits three limits that a per-seat phone system rarely makes you think about.

Segments, not messages

A segment is 160 GSM-7 characters, or 153 for each part of a longer message. A single emoji drops the limit to 70 characters, or 67 per part. A 175-character promo with an emoji is 3 segments. Sent to 5,000 contacts, that's 15,000 segments:

• 15,000 × $0.0075 = $113
• plus 15,000 × $0.0045 in carrier fees

Remove the emoji and trim the text to 160 characters, and the same campaign is 5,000 segments at the Standard rate plus 5,000 × $0.0045. Ready converts curly quotes, long dashes and ellipses to plain characters before sending, so those never change the count. Emoji still do.

Throughput and daily caps

Carriers don't publish an official rate card, so treat these as approximations. A fresh standard 10DLC campaign usually gets about 1 to 4 segments per second. At an assumed 2 segments per second, 15,000 segments take a little over two hours to go out.

T-Mobile also caps daily volume per brand based on trust score. The lowest tier is about 2,000 messages a day, and the tiers run up to about 200,000. Brand vetting ($79 Standard or $179 Enhanced, one-time) can raise your trust score. It only moves the daily cap if the score crosses into a new tier, and it doesn't change the per-second rate. Most senders don't need it.

Registration

Unregistered business texting gets filtered by carriers. Ready handles brand and campaign registration inside the app. There's no setup fee: you pay the first month, $25, when you submit. After that the monthly cost is $25 for registration and $2 per number. Most approvals take 2 to 7 days. If you're new to this, start with our 10DLC explainer. If a campaign gets rejected, here's how to rewrite sample messages so they pass.

A worked example: a five-person team

Here are our assumptions. Change them to match your own numbers.

• 2,000 opted-in contacts, one 1-segment campaign a week (4 per month)
• An assumed 20% of each campaign gets a reply, one segment each. Replies are billed like sends.
• 1,500 one-to-one texts a month from the inbox
• 300 answered call minutes a month
• One brand, one campaign, two numbers

Ready monthly cost (excludes the compliance surcharge):

• Campaign segments: 2,000 × 4 = 8,000
• Replies: 8,000 × 20% = 1,600
• Inbox texts: 1,500
• Total segments: 11,100 × $0.0075 = $83, plus 11,100 × $0.0045 in carrier fees
• Registration: $25 for registration + 2 × $2 per number = $40 a month
• Dialer: 300 × $0.025 = $8

That comes to about $330 a month: $222 in segments, $49.95 in carrier fees, $40 in registration and $18 in calls, before any compliance surcharge. The five seats cost nothing. Put that next to Quo's per-user price for five people on the plan you'd actually need. If your team sends half this volume, per-seat may come out ahead. If it sends double, it probably won't.

Scrubbing and landline validation are off by default. Each costs $0.003 extra per segment when you turn it on for an account. The standalone TCPA and DNC litigator scrub is $0.005 per contact, if you'd rather clean a list once before importing it.

The API and platform side

Ready differs most from a phone system in its API. Ready is built for software companies that text on behalf of their own customers. Each of those customers gets a sub-account with its own numbers and its own 10DLC registration, all managed through one REST API.

Here is a single send:

POST https://api.tryready.com/v1/messages
X-API-Key: <key>
Idempotency-Key: 6f1c2a9e-3b7d-4e21-9a0f-1d2c3b4a5e6f

{"to": "+12125550199", "body": "Your order #1042 has shipped.", "consent_attested": true}

POST /v1/messages/bulk accepts up to 100 recipients per call. GET /v1/registration returns registration status, and POST /v1/sub-accounts creates a customer's sub-account. Opt-outs and numbers on your Ban list are refused before sending and aren't charged. An API text sent during the recipient's quiet hours is held only if their window opens within 6 hours; otherwise it is refused and must be resent. A bulk call answers 200 either way, so the texts to resend are the results[] entries with error_code quiet_hours or QUIET_HOURS_BLOCK. A held text is charged only when it actually goes out. The full reference is in the messages docs and the quickstart. For a step-by-step build, see our SMS API integration guide.

A few other features matter at volume:

• Local presence: sends from your registered number closest to the contact's area code.
• Blue line: iMessage texting at $99 a month per line, plus 6 cents a segment.
• MCP server: lets AI agents send texts and manage campaigns.

Compliance: what helps and what's still on you

STOP and UNSUBSCRIBE replies are honored automatically, and the opt-out applies across every campaign. Quiet hours hold sends based on the recipient's area. Each bulk send and each API send that sets consent_attested records the sender's attestation: who sent it, to how many people and when. That record is not a per-contact consent log. You still need to store each contact's opt-in yourself, including when they opted in, the exact wording and the page URL. Campaigns, drip campaigns and automations wait up to 24 hours for the window; a one-to-one or API text is held only if the window opens within 6 hours, otherwise it is refused and must be resent; a one-to-one reply to someone who texted you in the last 24 hours goes out at any hour.

Text consented or engaged contacts only. Cold outreach belongs on the phone or in the mail. None of these features makes you immune to TCPA claims, which can run $500 to $1,500 per text. They lower your risk, and compliance stays your responsibility.

Which should you pick?

Stay on Quo if your team mostly makes calls and sends one-to-one texts, values its mobile apps and shared numbers, and doesn't run large campaigns.

Look at Ready if your outbound volume is growing faster than your headcount, if you need campaigns and drip campaigns with built-in compliance, if you're building an app that needs an SMS API with sub-accounts, or if you're a GoHighLevel agency replacing LC Phone. If you mostly need a team inbox, our Textline alternative comparison covers that side.

Use neither alone if power dialing is the core of your work. Pair a dedicated dialer with whichever texting tool you choose.

To test Ready, sign up. The first 20 one-to-one texts are free, and to send any text you need a card and a number ($2 a month, the first month charged when you get it). Use those texts before you register, because they end once a registration is paid for. Plug your real numbers into the worked example, and check pricing for the current rate.
