Default vs Specific Carrier

Default error codes are taken from the SMPP specifications (hex error code is also included for reference). Each carrier's implementation is slightly different, and we have highlighted any carrier-specific nuances in the rows below as follows: Yellow=Sprint, Blue=AT&T, Red=Verizon, Gray=Interop.
