SMPP 3.4 Protocol Specification Archive
For archive purposes, I’m posting a copy of the SMPP 3.4 Specification here. The SMS standards organization that created the specification has disbanded, and there are plans for their web site to be shut down. This doesn’t mean that SMPP is not still important for SMS. It remains the de-facto standard for application based SMS messaging. It’s just that the SMPP v3.4...
Read MoreProvisioning MMS Short Codes on the NowSMS MMSC
When using the NowSMS MMSC as an operator MMSC, one frequently asked question is how to provision short codes for MMS content providers, or Value Added Service Providers (VASP). The MMS specifications from the 3GPP define MM7 as the standard protocol for Value Added Service Providers to interface with operator MMSCs. Since many MMS content providers are existing SMS content providers, it may help...

Read MoreConnecting to an Operator MMSC with MM7
While NowSMS can function as an MMSC for direct MMS message delivery, this is not an option for most content providers, as most mobile operators block MMS message delivery from any MMSCs other than the mobile operator. In these situations, it is necessary to submit all MMS messages via an operator MMSC, or a service provider with operator MMSC connectivity. (For more information on how MMS works,...
Read MoreDynamic SMS Message Routing with HTTP Callbacks
If you need control over routing to particular SMSC connections, the logic that NowSMS uses for SMS message routing is described in detail in the following article: https://nowsms.com/routing-sms-messages-to-a-specifc-smsc-route For some installations, the routing control offered by NowSMS does not provide enough control. For these installations, an HTTP based callback exists which allows an...
Read MoreTON and NPI Settings for SMPP and UCP/EMI
One of the most confusing issues involved in setting up an SMSC connection is when your SMS service provider requires specific TON (type of number) and NPI (numbering plan identification) values. In the majority of cases, you can ignore any requirements that your provider has for these settings, because NowSMS uses intelligent default values. For SMPP environments, these are the rules that NowSMS...
