T-Mobile Jumps on the A2P 10DLC Bandwagon

Last January, Verizon introduced us to 10DLC, or 10-digit long code — a messaging solution created by mobile carriers for A2P (application-to-person) communication over local landline numbers. While most businesses were using these numbers for business texting, they were actually only intended for P2P (person-to-person) SMS traffic between family and friends. As texting over long codes grew increasingly popular, Verizon saw an opportunity to make 10DLC an attractive option for businesses, while also ensuring that the channel would be one that users could trust — free of spam and unsolicited communications. 

AT&T then followed suit in late 2020, and adopted a set of formal standards and registration processes for 10DLC numbers to better understand who’s using 10DLC for A2P and what  they’re sending across the network. This meant requiring businesses to register their brands with a third-party partner, in order to be vetted and assigned a “trust score” that determines message throughput. If a business decides not to register their brand and continues using their 10DLC phone numbers on the AT&T network, they will eventually experience disruption of service. 

Now T-Mobile is also jumping on the 10DLC bandwagon, and while there are still a number of things to be confirmed, here’s what we know so far:

  • Beginning Thursday, April 1, 2021 all outgoing and incoming SMS traffic to T-Mobile destination telephone numbers sent over the local A2P channel will incur a $0.003 surcharge. MMS messages will incur a $0.01 surcharge. This is in addition to the existing 10DLC surcharges that are currently being passed through from other carriers, such as Verizon Wireless, AT&T, and UScellular.
  • T-Mobile is leveraging the same campaign registry as AT&T, which means if you’ve already registered your brand with Plivo, you don’t need to take further steps. If you haven’t registered, we recommend doing so as soon as possible directly from the Plivo website. We don’t know the exact date, but T-Mobile does intend to block traffic that terminates in their network for any brands that aren’t registered in the coming months. In addition, any businesses that register after April 1 will incur a $50 activation fee from T-Mobile, which will be reflected in May’s invoice. Customers who are registered prior to April 1st will have this fee waived. 
  • Rate limits are not going into effect on April 1; exact dates are yet to be confirmed. We do know, however, that instead of throughput per minute (TPM), T-Mobile will be assigning each business a daily message throughput. 
  • T-Mobile hasn’t disclosed any information about campaign classification, but where throughput is not sufficient enough for a business after the vetting period, the business can opt for more throughput by paying a higher fee. 

If you’re a hobbyist, an independent developer, or a very small business, you don’t need to complete any registration at this time.

Details are still forthcoming, and we’ll update this page as soon as we have more to share. In the meantime, we recommend that all businesses who send a high volume of messages register their brands as soon as possible.
