Notes

Some phones and some networks validate the number you are texting from a phone and will only reliably allow texting of a full phone number.
If you have an A&A VoIP number on the same login as the SIM you can set the SIM ICCID on the incoming section of the VoIP number so that texts to that number are relayed directly to the SIM. There is a text charge for this. Not all of our VoIP numbers can accept incoming texts.
If you have an A&A VoIP number on the same login as the SIM you can set this on the SIM config on the control pages so that texts from the SIM are sent out as from that number. This incurs our normal outgoing text cost plus the SIP2SIM text cost, but we hope in future to apply a discount in this case.

There may be a small range of non UK mobile numbers to which mobile originated texts would go directly, i.e. bypassing the normal http posting, and presenting a different sending number.
At present there may be ways for some texts to reach the phone bypassing the http posting (i.e. a hidden number) but we expect to be able to fix this in due course.
Some phones (e.g. iPhones) send SMS to validate services (e.g. iMessage) and these will be chargeable.
