‼️ If you would like to send SMS text messages to prospects and clients from a 10-digit local phone number, you must register for A2P 10DLC.

In this article we explain:

Registering for A2P 10DLC will be simple!

There are three simple steps to registering for A2P 10DLC within the Trust Center:

  1. Create a business profile for your company in the Trust Center (one time)

  2. Register your brand(s) for A2P texting (one time)

  3. Select an A2P Plan: Low Volume or Standard Brand (one time) and register your phone numbers to campaigns/use cases (ongoing)

Two Types of A2P 10DLC Plans

There are two types of A2P Plans available to smrtPhone customers:

  • Low Volume Standard Brand

  • Standard Brand

Note: Any client who was previously registered for a "Starter Brand" plan will need to switch to one of these two plans by November 3, 2022. The Starter Plan is no longer available.

It's important to read through the options so you understand the benefits and limitations of each.

Once you are registered and your campaign use cases are approved, you will be able to connect your existing phone numbers to your A2P profile. There is no need to purchase additional phone numbers to become A2P compliant.

Low Volume (LV)

The Low Volume Standard Brand plan is for small businesses and businesses that use text messaging similar to a P2P fashion (personalized conversations, for negotiation and follow-ups) rather than high volumes of templated messages. Low Volume can be used for mixed messaging campaigns, multiple numbers per campaign, higher throughput, and lower filtering.

You can send up to 6,000 messages a day across all registered phone numbers (T-Mobile limits only 2,000 messages per day). Throughput is lower than Standard campaigns.

There is a limit of 400 phone numbers per campaign. LV plan has the option of one campaign type: Mixed Use, which covers conversational campaigns. You must provide sample messages as part of your registration process.

There is a one-time brand registration fee - of $4, a one-time campaign registration fee of $15, and ongoing campaign fees - of $1.50/month/campaign, both of which are significantly less expensive than regular Standard Plans. Fees are accrued upon registration approval, are passed through without markup, and are deducted from your credit balance.

Standard Brand Plan

A Standard Brand is a "full" registration for any business that needs to send more than 6,000 SMS segments and MMS per day to the United States or more than 2,000 per day to T-Mobile users.

This plan is for businesses with larger volumes of communication. You can have as many phone numbers registered as you like and the message limits per day are set based on your personalized Trust Score (calculated at the time of registration) but are commonly set to 200,000 messages per day.

Under the Standard Plan, you have many options for campaign types (including 2FA, account alerts, marketing promotions, and mixed-use/conversational.) You must announce the use case for each campaign and submit sample messages for approval.

The Standard Plan will require a registration fee (one-time) - of $44 and ongoing campaign registration fees - of $1.5 up to $10/month/campaign.

A2P Per Message Carrier Fees

⚠️Note: Per message carrier fees for A2P 10DLC are in addition to standard text messaging fees.

These are fees determined and required by the receiving carriers and vary depending on which one your contact uses. Because smrtPhone clients usually do not know the cell phone provider of their contacts, we cannot state a set price per message.

The most important thing to know is that Unregistered Messages will incur a higher per-message rate for AT&T, T-Mobile/Sprint, and any messages that use their network. Verizon has not currently voiced how they will handle unregistered traffic, but it is expected they will eventually announce a change in fee structure as well.

A2P Carrier fees per message, as of March 1, 2022:




Registered SMS




Registered MMS




Unregistered SMS




Unregistered MMS




This chart shows you will incur between $0.002- 0.003 for registered SMS and $0.0035 - 0.01 for registered MMS. You will incur between $0.0025 - 0.004 for unregistered SMS and $0.013-$0.005 for unregistered MMS - with the added possibility of your messages not being delivered.

Important reminders about A2P 10DLC fees

Additional fees are always difficult to swallow, but there are benefits to A2P 10DLC. While it may take a while to reach critical mass, the purpose of A2P 10DLC is to weed out spammers and scammers - which will make your legitimate business communications stand out and get noticed.

  • Verified messages will be funneled through separate, priority channels, improving delivery.

  • Verified messages are more likely to be read, trusted, and acted upon by consumers, improving response rates.

  • We are all consumers ourselves, and it will ultimately improve our own quality of life.

These fees are not singular to smrtPhone, but rather will be incurred on any technology platform that is used for business messaging. All VoIP and cloud based phone systems are considered A2P. (Read about other types of messaging besides A2P here).

➡️ Don't forget: Unregistered traffic is not guaranteed to be delivered or delivered in a timely manner, and it will incur higher per-message fees than registered traffic.
