Most texting bills grow between the quote and the invoice. An advertised per-message rate tells only part of the story. Carrier surcharges, registration charges, and quiet markups pile on later. Finance teams then discover the real number weeks too late. That gap distorts campaign forecasts for marketing teams. Signal house SMS Pricing puts every layer on a public rate card. That visibility turns budgeting from guesswork into simple arithmetic. Network rules, segment math, and volume tiers all shape the final number. Approval timelines matter too, since delays push launch dates back.
Carriers Set Fees, Providers Set Markups
Every US text crosses a mobile network first. AT&T, Verizon, and T-Mobile each charge a delivery toll. No business can negotiate those tolls down. Providers, however, decide whether to stack margin on top. A pass-through model forwards each charge at cost. A bundled model buries the surcharge in vague totals. Hidden margin compounds across thousands of sends.
Why Does Message Length Change the Bill?
US billing runs per segment, not per message. A standard SMS segment holds 160 plain characters. Push a promo to 300 characters, and two segments go out. That doubles both the rate and the carrier fee. Emojis shrink the limit further, since special encoding takes more space. Trimming copy is the cheapest saving available.
Published Rate Cards Remove Invoice Guesswork
Open pricing lets a team build a forecast before signing. Signal house SMS Pricing lists every cost line openly:
- Per-segment rates drop as monthly volume climbs.
- Carrier fees pass through with zero added margin.
- Campaign registration charges reach TCR without markup.
- Number rental costs sit on that same panel.
Brand vetting fees get listed alongside, priced to the cent.
What Does 10,000 Texts Really Cost?
Consider a clinic sending 10,000 single-segment reminders monthly. On published rates, the total lands near $115. About $65 covers the messaging rate itself. Network pass-through adds roughly $40. Campaign and number charges contribute around $11. That split surprises teams expecting one flat per-text price. At one million messages, network surcharges alone approach $4,000.
Which Carrier Charges Hit Hardest Per Text?
Outbound tolls vary by network:
- T-Mobile charges $0.003 each way.
- AT&T bills $0.003 per outbound SMS.
- Verizon collects $0.0031 per send.
- US Cellular takes $0.005 outbound.
Only T-Mobile currently bills inbound replies, which affects two-way support. MMS rates run higher, reaching a full cent on T-Mobile. A list heavy with US Cellular subscribers costs noticeably more.
Two Segments, One Overlooked Budget Line
Operator tolls stay fixed no matter who sends the message. Savings must come from somewhere else. Published rates show exactly where that somewhere sits. Cutting a 300-character promo to 160 halves its delivery cost. No contract renegotiation delivers that result overnight. At a million monthly sends, the edit protects about $4,000. Any finance lead scanning the rate card spots that lever. Transparent billing quietly moves cost control from procurement to copywriting.
FAQs
Are carrier fees included in advertised SMS rates?
Rarely, since most providers list them as separate charges. Budget an extra $0.0025 to $0.0045 per segment on top of any quoted rate, multiplied by segment count for longer texts.
Does Signal House add margin to 10DLC registration fees?
No, brand and campaign charges pass straight to upstream registries. The amount billed matches what TCR and the carriers collect, while platform rates and number rental carry their own published pricing.
How long does A2P campaign approval take?
Standard use cases clear in about 24 to 48 hours. Campaigns needing enhanced vetting can take longer, and accurate brand details on submission prevent most rejections.
When do volume discounts start applying?
Tiered discounts begin at 500,000 segments per month. Larger senders can request custom quotes from the sales team, while smaller accounts pay the same published rates.
