This page gives an overview to using our services for '''SMS'''.
 
==Inbound SMS==
This is where text messages are sent to us to deliverydeliver to our customers. We provide VoIP numbers in all UK area codes and some special services (e.g. 0800). However, at present, only a few of the numbers starting 01 and 02 can receive texts properly from most networks. All of our 01, 02 and 03 numbers can receive texts from Three properly. Attempts to send texts to other geographic numbers (i.e. those starting 01 and 02) cause a call to be made and the text read out by an automated system.
 
Where texts can be received properly, and this includes all cases where A&A customers send texts through us, the text will be sent on to you by your choice of means. This is based on the incoming text setting on the control pages for your number.
 
Our SIP2SIM service is also able to receive SMSs.

===SIP2SIM===
If you include a 19 digit string starting 89 which is the SIM ICCID for one of your SIP2SIM cards then the text will be passed to the SIM directly as a normal text. SIP2SIM charges apply for the SIP2SIM side as an incoming text. See: [[SIP2SIM and SMS]]
 
===HTTP===
If you put an entry starting http:// or https:// then we will attempt to send the text to you using HTTP (or HTTPS). If the URL ends with a ? or & then an HTTP GET is done with a set of form fields (i.e. name=value) containing information about the text. If the URL does not, then an HTTP POST is done using URL encoded form data. See: [[SMS API]] for more information.
 
 
==Outbound SMS==
==Other Information==
===Texts to SIP2SIM SIMs===
Using our normal text services setting the destination numerbnumber as the SIM ICCID (19 digit number starting 89) will send the text to the SIM.
 
You can also use the outgoing text gateway using the SIM ICCID as the username and a password as set in the SIM config on the control pages. In this case you do not need to specify the 'da'.
 
===Multipart texts===
Where possible multi-part texts are automatically handled, concatenated before being passed to you, or split from your message in to parts. Unfortunately, not all of the systems to which we interconnect handle multi-part messages sensiblesensibly, and this can result in a multi-part message being delivered as multiple separate text messages.
 
===Itemised billing===
If you have a presentation number set up for your VoIP, this will be used unless you specify an originator. You can specify the presentation number, or the main number.
If you ask us, we can allow sending of text based originators on a per account basis. You will need to be an established customer. This can be withdrawn at any time.
 
===UTF8 Character Sets===
The SIP2SIM service does handle all of the GSM character set options, including the 7 bit character set with escaping, the 8 bit character set, and the 16 bit character set with UCS16 surrogates for full unicode.
 
Internally we convert all messages to UTF-8. If we are sending messages to your own gateway or email they will be in UTF-8.
 
Our outgoing SMS carriers to external mobiles do not support everything, sadly, and so some characters may get lost on the way. We can only suggest testing yourself to confirm.
 
Sending SMS to the SIP2SIM service can be done via our gateway/api and we accept UTF-8 which we will convert as needed in to the necessary GSM character coding scheme and split for multi part messages automatically.
 
 
===SMS error codes===
 
This is a list of internal error codes which may be shown on CDRs if something went wrong:
 
* -201 no target found for incoming SMS to customer
* -204 error while HTTP posting to customer's server
* -202 and -203 invalid destination email address
* -301 no destination number
* -302 and -303 no SMS content to deliver
* -304 this is a status report, not a normal SMS
* -305 message billing error
* -306 too many message parts
* -702 failed to route message - possible if sending to a totally invalid number
* -801 and -802 are decoding errors while packing to TPDUs
