Here’s how SuperPhone buys, manages, and assigns phone numbers on your behalf:
Multiple Phone Numbers
When you create a SuperPhone account, you are prompted to choose a number in your preferred area code. Choose your area code wisely because SuperPhone spins up a new a new number in that area code for every group of 500 people that text you.
Why the need for multiple numbers?
As you scale up your network and start to send/receive texts from hundreds of people, most telecoms will automatically blacklist phone numbers and prevent your messages from getting through.
Groups of 500
Carrier blacklisting is purely volumetric, meaning that your number gets flagged when you’re texting more than a normal cell phone user. Having a separate number for each group of 500 people who text you prevents this and ensures delivery. SuperPhone automatically does this work for you in the background.
Having multiple numbers also increases your rate of delivery — sending 100 messages via a single number takes 100 seconds, while sending 100 messages via 10 different numbers takes only 10 seconds.
New Assigned Number Auto-Message
When SuperPhone assigns a new number to someone who’s texting, they will automatically receive a message telling them to save the new phone number. You can also choose to send your contact a dynamically generated vCard so they can easily save that number for you. Learn more about customizing that auto-message in our Setting up via Desktop video.
How Much Does Each Additional Number Cost?
This personal method of staying in touch with large groups of people is extremely affordable ($1 per number/per month in the US) and ideal for 2-way messaging and relationship building.
For every group of 500 people that text you, you add $1 to your monthly bill. For 5,000 people, you’d be paying $10 ($1 for each of 10 numbers) monthly for your number pool.
