Can you text a landline? What happens and what it costs

Usually, no. Most US landlines can't receive an SMS. Depending on the phone company, a text sent to one either fails silently or, in a minority of cases, gets converted into a robot voice call that reads the message aloud. If you're sending one text to one person, that's a curiosity. If you send a text to landline numbers sitting in a 10,000-contact list, it's wasted segments, a misleading delivery report and leads you think you reached but didn't.

This post covers what happens on the carrier side, why landlines end up on lists that are supposed to be mobile, what that costs on a campaign, and how to filter them out before you send. We make Ready, so the last part shows how we handle it, including when the filter isn't worth paying for.

What happens if you text a landline?

If you text a landline, the message usually goes nowhere. The phone company either rejects it, drops it without telling you, or in a few cases turns it into an automated voice call that reads the text aloud.

You often get no clear error, so it looks sent on your end. The person on the other end never sees it.

Why most landlines can't receive texts

SMS is a mobile network feature. A mobile number is tied to a carrier that runs the messaging infrastructure: it receives the message, finds the handset and delivers it. A traditional landline (copper or a cable-company home phone) sits on voice infrastructure that was never built to accept a text.

When your message reaches a number like that, the outcome depends on the landline provider:

• The message fails. This is the most common result. The carrier rejects it or it goes nowhere, and you may or may not get a clear failure status back.
• Text-to-voice conversion. Some landline providers turn the text into an automated call: a synthetic voice reads your message, sometimes repeating it. For a promo with a link and "Reply STOP to opt out," the result is confusing at best.
• The landline has been text-enabled. Some businesses put SMS on their main office number through a hosted messaging provider. Those numbers can receive texts even though a line-type lookup may still report them as landlines.

The third case is mostly about business-to-business texting. For a consumer list, assume a landline means "can't text."

What about VoIP numbers?

VoIP numbers (Google Voice, app-based numbers, many business phone systems) sit in between. Many receive SMS without problems. Some don't, and some are temporary numbers people use to dodge forms. A line-type check reports VoIP as its own category, so you can choose how to treat it instead of guessing.

Text to landline: how they get onto your list

If your list is opt-in, nobody typed "please text my landline." Landlines get in anyway:

• "Phone" form fields. A form that asks for "phone" instead of "mobile number" collects home and office numbers. Older customers especially still list the house phone.
• CRM imports. Records merged from an old database, a POS system or a trade show scanner carry whatever number was on file, often a work desk line.
• Ported numbers. A number can move between mobile and landline status. A contact who was textable three years ago may not be today.
• Call-first workflows. Service businesses that book by phone save the number the customer called from, which is often a landline.

None of this is a compliance failure on its own. It's a data-quality problem that turns into a cost problem when you send a campaign. Line type is one check. Whether the number is real and in service is another, which we cover in how to check if a phone number is real and can receive texts.

Why landlines waste money on a campaign

There are three costs, and the per-text charge is the smallest.

1. The segments

How providers treat a text to a landline varies. Some bill the attempt, some don't, and some only fail it at the carrier after the meter has run. If yours bills attempts, every landline on the list is a full message charge for nothing. Check your provider's terms. "Delivered" and "billed" are not always the same thing.

2. A misleading delivery report

A campaign report showing 94% sent tells you nothing if 8% of the "sent" numbers were landlines that could never show the message. You'll attribute a weak reply rate to the copy or the offer when part of the cause is the list.

3. The leads you think you reached

This is the expensive one. An appointment reminder that goes to a landline doesn't prevent the no-show. A "your quote is ready" text sent to a home phone doesn't get the quote read. The contact didn't ignore you. They never got it. The fix is to identify the landlines and call them instead.

A worked example: one campaign, with and without landline filtering

Assumptions, labelled as such:

• 5,000 opted-in contacts, collected over a few years through a web form that asked for "phone"
• We'll assume 8% are landlines (400 numbers). Your share could be far lower on a recent mobile-only list or higher on an old one.
• One 150-character message, plain text, no emoji: 1 GSM-7 segment (under the 160-character limit)

On Ready Standard, each segment costs $0.0075 plus a $0.0045 carrier fee.

Without filtering, if your provider bills attempts, the 400 landlines cost:

400 × 1 segment × ($0.0075 + $0.0045). At this list size that's around ten dollars per campaign, plus 400 contacts who never saw the message.

Ready's all-in prices per segment include the carrier fee but not screening: Scrub lists and Number validation, the two switches in Settings under Compliance, each add $0.003 per segment when switched on, shown as screening on your bill, and both are off by default. Unless you turn the opt-out footer off, the first text to each contact, and one again from time to time, also gets "Reply STOP to opt out" and your business name if the message does not already have them, so a text close to the segment limit can bill one more segment.

A number Ready has already seen as a landline is refused up front and not charged, on every account. Switching on landline validation adds a live line-type lookup for numbers Ready hasn't seen yet; a landline it finds is refused and not charged (the number check itself can still be billed). The 4,600 mobile numbers that do send carry the validation surcharge of $0.003 per segment:

4,600 × 1 segment × $0.003 = $13.80

The honest read on that math

On a single one-segment campaign, validation can cost more in surcharge than it saves in wasted segments. The break-even is roughly where the landline share of your list equals $0.003 divided by ($0.0075 + $0.0045). That works out to around one landline in every five numbers, and fewer for multi-segment messages. A clean, recent, mobile-only list won't reach that.

The case for filtering rests on the other two costs: accurate reporting, and knowing which 400 contacts need a phone call instead of a text. If your list came from a form that collected "phone," or from an old import, it's usually worth turning on. If every number came from a "mobile number for texts" field last month, you can probably leave it off.

How Ready handles landlines

Here's what we offer, with the prices from our billing:

A few specifics:

• Validation and scrubbing are separate switches. Validation answers "can this number receive a text?" Scrubbing answers "is this a known litigator or DNC number?" Turn on either, both or neither.
• Opt-outs, numbers on your Ban list and known landlines are refused, not charged. A refused send doesn't hit your prepaid credits.
• Checking at intake beats checking at send. If you control the form, call the validate endpoint when the number is submitted and ask for a mobile number on the spot. That clears the problem before it reaches a campaign:

X-API-Key: <your key>

The response fields are documented on the docs site. We won't paraphrase them here, so build against docs.tryready.com instead of this post. If you're also wondering which network a number is on, phone carrier lookup covers that separately.

What to do with the landlines you find

Don't delete them. A landline in your CRM is still a customer who gave you a number.

1. Tag them. Mark the record "landline" so future campaigns skip it automatically.
2. Call the ones that matter. For reminders, quotes and follow-ups, a short call works where a text can't. The Ready Dialer lets you click-to-call from the dashboard or GoHighLevel at $0.025/min. A two-minute reminder call costs $0.05. It has no auto-dialing or voicemail drop. It's a manual dial pad, which suits a short list of known contacts.
3. Ask for a mobile number. At the next touchpoint (a call, a checkout, an email), ask whether they'd like texts and on which number. A new number needs its own opt-in. Consent given for one number doesn't carry over to another. If that distinction is fuzzy, what opt-in means for text messages walks through it.
4. Fix the form. Relabel the field "Mobile number (for texts)" and validate at submit.

Calls to landlines carry their own TCPA and Do Not Call rules, separate from texting rules. Consent and DNC still apply. Compliance remains the sender's responsibility, and our tooling reduces risk rather than removing it.

The practical takeaway

You generally can't text a landline. At best the message fails quietly, and at worst a robot voice reads your promo to someone's kitchen phone. On a campaign, the per-text waste is small. The bigger losses are the skewed reporting and the contacts you never actually reached.

If your list came from "phone" fields or old imports, filter landlines and call those contacts. If it's a fresh, mobile-only opt-in list, the surcharge may not pay for itself, and that's fine.

FAQ

Can I text a home phone?

Usually not. A home phone on a traditional landline can't receive SMS, so the text fails or turns into a voice call. If the number is a VoIP line, it may well receive texts.

Can a landline send a text?

Most traditional landlines can't send texts either. Some providers offer text-enabled business lines, and a mobile or web app can send texts for you.

Can you send a text to a landline from your cell phone?

You can hit send, but on most US landlines the message won't arrive. Some landline providers convert it to an automated voice call. Others drop it. You often won't get a clear error back.

Will I know if my text went to a landline?

Not reliably. Some failures come back with a status and some don't. A line-type check before sending is more dependable than reading delivery reports afterward.

Does Ready charge for texts sent to landlines?

A number Ready has already seen as a landline is refused up front and not charged, on every account. Switching on landline validation adds a live line-type lookup for numbers Ready hasn't seen yet (the number check itself can still be billed). Validation adds $0.003 per segment to the texts that do send, and it's off by default.

Can a business landline receive texts?

Some can, if the business has text-enabled its number through a hosted messaging provider. A line-type lookup may still report it as a landline, so for B2B lists, treat those results with some care.

Should I remove landlines from my list?

Remove them from text campaigns, not from your CRM. Tag them, call the contacts who need reaching, and ask for a mobile number with fresh opt-in at the next opportunity.
