Texting from your tracking number: only five call-tracking vendors publish what a message costs
Most call-tracking platforms meter minutes loudly and SMS quietly — only five name a per-message rate, only Convirza breaks out MMS, and the spread between cheapest and dearest text runs better than 20x.
Texting a caller back from the same number that rang — appointment confirmations, “missed you, here’s a link,” review requests — is a feature most call-tracking vendors technically support and almost none price out loud. They publish a per-minute call rate on the front of the box and leave SMS to the fine print or a sales call. In our dataset of 16 call-tracking vendors, exactly five name a per-message SMS rate, and only one names an MMS rate. That alone collapses the buying decision.
Here is every vendor in the dataset that publishes what a text costs, cheapest message first.
| Vendor | Tier (priced) | SMS / message | MMS / message |
|---|---|---|---|
| Dialics | Pay As You Go ($0 base) | $0.0024 | not published |
| Convirza | Agency ($149/mo) | $0.025 | $0.045 |
| Convirza | Starter ($29/mo) | $0.03 | $0.05 |
| CallRail | Lead Tracking ($50/mo) | $0.03 | not published |
| WhatConverts | Call Tracking ($30/mo) | $0.03 | not published |
| WildJar | Starter ($39/mo) | $0.05 | not published |
The marginal-text spread runs from Dialics at $0.0024/SMS to WildJar at $0.05/SMS — a gap of more than 20x on the per-message line. If texting is a core part of how you work a lead, that column matters more than the monthly base, and it is the column nobody puts on the pricing hero.
The cheapest text, and why it’s not the cheapest platform
Dialics wins the per-message line outright at $0.0024/SMS, an order of magnitude under everyone else, and it carries no monthly base at all — the platform is pure pay-as-you-go (local calls $0.045/min, numbers $1/mo). For a high-volume texting workflow on a thin budget, that is the floor, and nothing in the dataset is close.
But “cheapest per message” and “cheapest to run” are different questions. Dialics publishes no named monthly plan, no bundled minutes, and a lean integration list (Google Ads, Zapier, API). The $0.0024 rate is real; the trade is that you assemble everything yourself and live on metered usage.
CallRail and WhatConverts: same text rate, one platform price
CallRail and WhatConverts both land on $0.03/SMS — and in both cases that is a platform-wide rate, not a per-plan one. It is the same $0.03 whether you are on CallRail’s $50 Lead Tracking entry tier or its $195 top tier, and the same on every WhatConverts tier above the $30 entry plan. So for these two, your SMS cost is fixed the moment you sign up; the tier you choose buys you features (form tracking, conversation intelligence, usage credits), not a cheaper text.
That $0.03 is the median of the published field, and it comes attached to the two most heavily integrated platforms here — CallRail lists 700+ integrations, WhatConverts ships Zapier access to 2,000+. If you want texting and a deep CRM/ads stack, this is the unremarkable, predictable middle.
Convirza is the only vendor that prices MMS — and it moves the price down as you go up
Convirza is the only entry in the dataset that publishes an MMS rate at all, and it does it on both tiers. Picture/video messages cost $0.05 on Starter ($29/mo) and $0.045 on Agency ($149/mo); SMS runs $0.03 then $0.025. That makes Convirza the inverse of CallRail and WhatConverts: paying for the higher tier actually buys a lower marginal message rate (and a lower per-minute rate, $0.05 vs $0.08, and cheaper numbers, $1.00 vs $3.00). If your campaigns lean on MMS — coupons, before/after photos, anything visual — Convirza isn’t just the cheapest option for that, it’s the only one that will quote you a number without a sales call.
The honest reading
If your question is strictly “what does a text cost,” the answer is a short list: Dialics $0.0024, Convirza $0.025–$0.03 (plus MMS at $0.045–$0.05), CallRail and WhatConverts $0.03, WildJar $0.05. Everyone else — CallTrackingMetrics, Ringba, Nimbata, Infinity, and the quote-only incumbents like Invoca and Marchex — either doesn’t publish an SMS rate or doesn’t publish pricing at all, which for a buyer who needs to budget messaging is the same as not offering it.
Dialics owns the per-message floor by a wide margin; Convirza owns MMS by being the only one in the room; CallRail and WhatConverts sell texting as a flat $0.03 footnote to a much bigger platform. Pick on the message rate only if messaging is genuinely the workload — otherwise it’s a tiebreaker, not the deciding line. Either way, five names is the entire field, and we list the rate and the source page behind each one.
