SMS reminders let attendees opt in to receive a text shortly before their first selected talk on each event day. Use them when you want to give attendees a timely prompt without sending a message before every talk.
Before you start
SMS reminders are available on active paid HeySummit plans.
HeySummit currently sends SMS reminders to supported mobile numbers in the United Kingdom, United States, and Canada.
Attendees outside supported countries can still save their mobile number and opt in. They will not receive reminders until their destination is supported, even when your account has credit.
Each attendee must enter a mobile number and opt in during checkout or from their attendee profile.
Your account needs enough SMS credit for the reminder to be sent.
Turn on SMS reminders
Open your event dashboard and go to Event Settings > Email & SMS.

What attendees receive
An opted-in attendee receives one SMS reminder shortly before their first selected talk on each event day.
If an attendee selects several talks on the same day, HeySummit does not send a separate SMS before every talk.
Attendees can opt in during checkout or from their profile. They can opt out by replying STOP or by changing their profile preference.
Message and data rates may apply.
Understand SMS credit
Each sent reminder uses SMS credit. Current USD costs are $0.08 for the United Kingdom, $0.017 for the United States, and $0.022 for Canada. Accounts billed in another currency see the converted amount in their billing currency.
The Success plan includes $50 of monthly SMS credit.
Included monthly credit and recurring purchased credit renew each calendar month and do not accumulate. Monthly credit is used before one-off top-ups. Only the unspent balance of a one-off top-up carries forward; standard one-off credit does not expire.
All active paid plans can buy additional one-off SMS credit. One-off credit does not expire.
From My Account > Billing > Manage Capacity, you can buy credit manually or enable automatic top-ups. Automatic top-ups require billing details and a saved card.
If your balance runs out, SMS reminders pause until you add credit or a configured automatic top-up succeeds.
A sending attempt can initially debit SMS credit. If the provider confirms a supported non-billable rejection, HeySummit automatically credits that amount back. This does not mean every failed or undelivered message is free, and it does not promise refunds for historical attempts. Adding credit does not enable reminders to unsupported countries.
Check volume and delivery
The SMS Reminders panel estimates sends from the current schedule and attendee opt-ins.
Your account's available SMS credit is the normal sending limit. There is no separate reminder-count allowance to request. Reminders pause when there is not enough credit for the next eligible reminder. Check your balance and automatic top-up status in My Account > Billing > Manage Capacity. Review the top-up amount, low-balance threshold and spending cap before enabling automatic top-ups.
If attendees cannot see the opt-in, confirm that SMS reminders are enabled for the event. An unsupported mobile-number country does not prevent attendees saving their number or opt-in.
If reminders stop, check your SMS credit and automatic top-up status in Billing.
Before buying credit, check the supported-country notice in SMS Reminders or Billing. Adding credit does not enable delivery to an unsupported destination.
