I don't think this is possible. You can send raw SMS PDU's with Diafaan SMS Server to send WAP push or picture messages to a mobile phone but I can't imagine that you can send SIM card commands via an SMS message from another phone or GSM modem. That would make the mobile phone far too vulnerable for attacks.

For this kind of functionality you almost certainly need direct access to the SMSC of the mobile operator that provided the SIM card.

The Clickatell 'Communicator / Central' login is available for older accounts but if you send a request to Clickatell they might be willing to enable this for a new account as well (they did this in the past). When Clickatell switched to the new platform, binary messages were not supported so we could not add this to the 'Platform' option in Diafaan SMS Server. But the current documentation suggests that this now is an option so we will test this out and add it to the new version of Diafaan SMS Server if it works well.

A number of services support SMPP but often only upon request and sometimes only for large accounts. According to their website, Clickatell also supports SMPP for large accounts. We often use the MessageBird SMPP service for testing, they can set up an SMPP account upon request. I don't know if MessageBird requires a minimum message throughput for SMPP.

When you search Google for SMPP services you will probably find a few available in your own country that you could contact.
