DB Mail is working with other carriers but not sprint

Question

So the database mailer sends the sms to Verizon, att, Cricket etc.. but when sending to a sprint phone number using messaging.sprintpcs.com they receive a text with what looks to be the message encrypted.

We have tried with with different sprint users and different phones. All the same results.

Thank you for your time.

My issue was that @body_format of the sp_send_dbmail was set to 'html'. While other services were okay with this, Sprint has strict character limits that were causing issues.

DECLARE @BodyFormat nvarchar(20) = 'HTML'

IF ISNUMERIC(SUBSTRING(@EmailTo, 1, 7)) = 1
    SET @BodyFormat = 'TEXT'

EXEC msdb.dbo.sp_send_dbmail
                @profile_name = 'Profile',
                @from_address = @EmailFrom,
                @recipients = @EmailTo,
                @copy_recipients = @CC,
                @blind_copy_recipients = @BCC,
                @subject = @Subject,
                @body = @Body,
                @mailitem_id = @MailItemID OUTPUT,
                @body_format = @BodyFormat;
