There are several reasons why your subscriber may get an error message when trying to opt in to your list. Error messages are related back to the user's or cellular provider's side in most all cases. The following list of errors are common among all SMS marketing platforms and short codes.

Cellular Service Blocked/ Unavailable/ Not allowed - Provider Error
    •    Message returned: Can vary depending on service provider. The typical returned message reads, “Service Blocked, Service unavailable, Not allowed, or service access denied." 

1. To resolve this, the potential subscriber must call their cellular provider and ask for short code communications to be unblocked.
2. This is rare and usually only seen about 4% or less of all subscribers

Cellular providers short code communications down (Highly unlikely) - Provider Error

1. REPORT THIS IMMEDIATELY TO Info@SlickText.com
       •    This is very rare but can happen. When this happens all short codes can be down for a particular cellular provider across the nation. If a customer can text into the system but does not receive an auto reply, this could mean their service is delayed or their provider is experiencing an outtage.
       •    There is nothing you can do about this, as it is an issue with the provider’s service.
       •    One sure fire way you can tell a provider is down is that you can still send and receive a short code message on another provider like AT&T or Verizon.
       •    After the provider is back up and running, the auto-reply will be delivered.
       •    Wait times for the provider's fix can range anywhere from 15 minutes, hours, to even a day or two.
       •    Reasons for providers being down or delayed can include system updates, over burdened traffic, slow service, no service area, or other.
