On September 1, 2020, Verizon began imposing a surcharge of $0.0025 for every outbound SMS message segment on its toll-free phone numbers. We pass this fee through to you with no additional upcharge, and the fee appears as a separate line item on invoices.
Starting July 1, 2021, both T-Mobile and AT&T are also applying carrier passthrough fees for traffic terminating on toll-free numbers, on both SMS and MMS messages:
AT&T SMS Outbound: $0.0025/message
AT&T MMS Outbound: $0.003/message
T-Mobile SMS Outbound/Inbound: $0.0025/message
T-Mobile MMS Outbound/Inbound: $0.01/message
