15% of wireless subscribers from major carriers in the US are willing to try direct-to-bill mobile payments, amounting to over 30 million people. This would displace over 9.1 billion debit transactions per year, valued at $760 million per month in debit transactions across the large carriers. Consumer sentiment around direct-to-bill mobile payments is similar for the major carriers, with most consumers not ready yet due to preferring credit or debit cards or not trusting their mobile provider.
