Häufig gestellte Fragen (FAQ)

ASPSMS has provided a numeric originator function (normally a mobile phone number) since 2001. ASPSMS continues to provide that function generally, but unfortunately some of the operators have begun to block some of the numeric originators in their GSM networks. Normally blocking emerges only when using a local inland number is specified as an originator.

ASPSMS is informing in its network list about the GSM networks with restrictions for numeric originators.

If there is a restriction with numeric originators in a specific network, the SMS behaviour is not always the same. Scenarios below are possible, when sending with a numeric originator to a restricted network:

• SMS with an inland number as an originator is not going through, but SMS with originator number from abroad is going through without problems.
• SMS is going through but the destination network automatically changes originator to a specific short-code.
• SMS is going through without problems.

Unfortunately ASPSMS cannot do anything about these restrictions, because it is implemented directly by the specific destination mobile operator. ASPSMS recommends users to test the specific numeric originator, when sending to networks which are marked as restricted.

For these networks with a numeric originator restriction, ASPSMS recommends clients to use an international numeric originator or purchase a global two-Way number from ASPSMS, which can be used as a numeric originator.
