At this time, 160 characters is the industry-supported standard maximum for text messages across all carriers/mobile service providers and phones in the U.S. In Canada, 140 characters is currently the maximum. 

Some smartphones such as the iPhone and the iMessage app have supported longer messages for years, but there is still a small percentage of wireless subscribers who rely on older phones without those capabilities … and the governing body that regulates these standards hasn’t changed them in several years as a result.

An easy workaround for this issue is to set up a message flow: First, use a keyword’s auto-confirmation message to provide the main content and include a link to a website or other media where the rest of your message, call to action, coupon, form, etc. is hosted.

Alternatively, you can use a keyword’s auto-confirmation message to provide the main content, then go to Messaging in your dashboard and create a series of autoresponders that are timed to provide the remaining content in your preferred sequential order.

You can pre-schedule autoresponders to go out a few hours, days, months, or even years in advance!

Pro tips:

  1. Be sure to leave a 1-2 minute delay for your first queued autoresponder so your subscribers don’t receive the autoresponder content before they receive your auto-confirmation message.
  2. Similarly, a good rule of thumb is to leave at least a 1-2 minute delay between autoresponders to allow time for each message to be received and read before your subscriber is interrupted by the next text in your message flow.
