Texting from a business landline: how to enable it

Your business number is on your trucks, your Google profile, your invoices and probably a sign you paid real money for. Customers already text it. Most of those texts go nowhere, because a traditional landline can't receive SMS. The sender sees "delivered" or nothing at all, and you never know they tried.

You don't have to change numbers to fix this. Some providers can text-enable a landline while voice calls keep ringing exactly where they ring today. Ready doesn't do that yet; on Ready you port the number in or add a new local number. This post covers how each option works, which one fits, what registration you still need, and what it costs, with the math shown.

What "text-enabling a landline" actually means

Every US phone number has two separate routing records. One says where voice calls go. The other says where text messages go. On a plain landline, the messaging record points nowhere, so texts to it fail.

Text-enablement, usually called hosted SMS, updates only the messaging record so texts route to a messaging provider. Your voice service doesn't change. Your phone company keeps the calls and bills you the same way. A different provider handles texts in and out.

Because only the SMS route moves, three things are true:

• Calls are not interrupted. Nothing touches the voice side.
• You have to prove you own the number. This is normally done with a letter of authorization (LOA) signed by the account holder, often with a recent phone bill showing the number.
• Only one provider can hold the SMS route at a time. If an old texting app, a previous marketing tool or your VoIP system already claimed it, that has to be released first. This is the most common reason text-enablement stalls.

Three ways to text from your existing number

Text-enabling is one option. Depending on your setup, porting or adding a second number can be the better fit.

A few honest notes on each.

Hosted SMS is the least disruptive for businesses keeping a landline. Ready doesn't offer it today, so this route means another texting provider. It can fail if the number type or current carrier doesn't support it, or if someone else holds the SMS route.

A full port is how Ready texts from the number you already have: on the Numbers page, choose Port numbers. It's a bigger decision. Porting voice means your phone company is no longer handling calls, so you need somewhere for calls to land on day one. Ready has the Ready Dialer for click-to-call and inbound calls that ring the open dial pad in the dashboard or GoHighLevel. It's billed at $0.025/min, answered time only. It isn't a full phone system, though: no call queues, transfers or voicemail drop. If your front desk depends on those, keep voice with your phone provider and add a new local number for texting, or use a provider that offers hosted SMS.

A second number is unglamorous but quick, and sometimes it's the only option. Customers who already text your main number won't reach you there, so put the new number in your signature and booking confirmations.

You start the port yourself in Ready, from Numbers, then Port your numbers. Porting is free; the number is $2 a month once it lands. Most ports take 1 to 3 weeks, and the number keeps working with your old carrier until then. Whether a specific number can be ported depends on the number type and the carrier behind it; if you'd like us to check first, email support@tryready.com.

Registration still applies to your old number

A landline that has been yours for twenty years gets no head start with carriers. Once it sends business texts, it's an application-to-person (A2P) sender and needs A2P 10DLC registration: a brand (your business) and a campaign (what you send and how people opted in). Unregistered business traffic gets filtered by carriers, so skipping this means texts that quietly don't arrive.

On Ready, registration is handled in the app:

• No setup fee. The charge at submit is the first month: $25.
• After that, monthly is $25/mo for registration + $2 per number.
• Most approvals take 2 to 7 days.

On Ready, the app files the campaign for you; over the API you set use_case. Either way, the campaign use case should match what you'll actually send. A landline turned texting line is usually conversational or appointment-focused, not promotional. Registering as marketing when you mostly send reminders causes trouble, which we cover in matching your use case to what you send. For the full fee breakdown, see 10DLC cost: every fee explained.

If your landline runs through a VoIP platform such as RingCentral, Nextiva, Zoom or GoTo, check whether that platform already offers texting and its own registration flow. Here's what each one requires.

The step-by-step checklist

Here's the order that avoids most of the back-and-forth:

1. Find your current bill. You need the exact account holder name, service address and number as your phone company has them. Mismatches are the top reason LOAs get rejected.
2. Check whether anything else holds the SMS route. Think back: did a review tool, scheduling app or old texting service ever "add texting to your number"? If so, cancel it and ask them to release the number.
3. Decide: port, add a number or text-enable elsewhere. Use the table above. On Ready, a new local number is the quickest and doesn't touch calls.
4. Sign the LOA as the authorized account holder.
5. Get your website ready for registration. Carriers check for a privacy policy and terms that mention texting. Our website and privacy policy requirements post has templates.
6. Submit brand and campaign registration. Do it in parallel with the port, not after, so the two finish around the same time.
7. Test both directions. Text the number from your own cell, reply from the inbox, then text STOP and confirm the opt-out is recorded.

One timing note: your first 20 texts on Ready are free one-to-one sends, and they end the moment a registration is paid for. Use them for testing before you register, not after.

What it costs: a worked example

Assume a small service business ports its landline to Ready. In a typical month it sends 400 one-to-one appointment reminders and confirmations and receives 150 customer replies. Every message is under 160 plain characters with no emoji, so each one is 1 segment.

On Ready, sent and received texts are both billed at the Standard rate of $0.0075/segment, plus a $0.0045 carrier fee per segment.

• Segments: 400 sent + 150 received = 550 segments
• Message charges: 550 × $0.0075
• Carrier fees: 550 × $0.0045, itemized separately
• Registration: $25 for registration + $2 number

That figure excludes the compliance surcharge. TCPA/DNC scrubbing and landline validation each add $0.003 per segment when switched on, and both are off by default.

Watch the segment count. Add one emoji to a reminder and the limit drops to 70 characters. A 140-character reminder with a smiley becomes 3 segments, so those 400 sends jump from 400 segments to 1,200.

To be straight about price: raw CPaaS providers like Twilio, and GoHighLevel's LC Phone, charge less per message than Ready's Standard rate. If you're a developer wiring texting into your own stack, one of those may suit you better. What Ready includes is the rest: in-app registration, an Inbox, automatic STOP handling across campaigns, quiet-hours holds, optional litigator and DNC scrubbing, and a native GoHighLevel integration if that's where you work.

Things that go wrong (and how to spot them)

"The number is already enabled elsewhere." Someone holds the SMS route. Track down the old service, cancel it and request a release. This is the slowest problem to fix, so check early.

Texts send but replies don't arrive. The SMS route may not have fully updated, or your old provider still has a stale record. Test from more than one carrier (a T-Mobile phone and a Verizon phone, for example) before you announce texting to customers.

Approved, but texts get filtered. Registration covers who you are, not what you write. Link shorteners, all-caps and certain content still get blocked. See why approved campaigns still get filtered.

Other businesses can't text you. Some senders run line-type lookups that flag landlines. A text-enabled landline can still show as a landline in those databases for a while, and some senders filter landlines out. You can't control their lookups, but it explains why a few automated texts never show up.

Texting outside reasonable hours. Ready holds sends outside permitted local hours based on the recipient's area and sends them later, charged only when they go out. That lowers risk, but you're still responsible for who you text and why. Text people who gave you their number or asked you to reach them, and handle cold outreach by phone or mail. 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.

The practical takeaway

If you want to keep your landline exactly as it is, hosted SMS from a provider that offers it keeps calls put; Ready doesn't offer that today. On Ready, port the number if you're leaving your phone company anyway and your call handling is simple, so customers who already text it finally reach you and nothing gets reprinted. Add a second number if you'd rather leave the landline alone.

Whatever you choose, register for 10DLC at the same time. Most approvals take 2 to 7 days, and it's the difference between texts that arrive and texts that disappear. If you'd like us to check whether your number can be ported before you commit, email support@tryready.com. When you're ready to set it up, you can create an account and send your free test texts first.
