In your FAQ, re question 14: You can now check your balance by creating an account & registering your phone number at the 7/11 Speakout website. Then logging onto your account will show you your balance/expiry date.
You can also add more than 1 phone number to your account, so if other family members have speakout phone numbers, you can check their account balances/dates.
BTW, thanks for a great website…very helpful…
