It seems that Clickatell.com has changed their pricing for US customers.
In the past they offered an inexpensive solution ('shared short code'), and a very expensive - high end solution where you have your own short code. $1700 set and $900 per month.
I have now heard from two new customers that Clickatell.com's inexpensive solution is no longer available for US customers.
RBPro has no support built in for Short Code as the requirement is new, and I am not prepared to spend the outrageous sums that Clickatell seems to want from US customers now.
I am currently looking at switching to textmarks.com, but I cannot say how soon that will happen. see update below
## UPDATE ##
SMS in the USA is now off the table, indefinitely.
My research with alternate SMS providers in the US has hit a brick wall.
The opt-in requirements of US carriers are extremely strict, apparently this is exactly how Clickatell got their 'shared short code' shut down.
US carriers require the recipient to opt-in by one of a couple of different means - none of which can be handled by RBPro.
Sprint has cut off carriers such as Clickatell (a global sms aggregator) from allowing shared short code messages to be sent.
Whats a shared short code?
To save costs, carriers such as Clickatell allow smaller companies to use a shared short code because they can't afford the really high costs of getting their own short code ($900 a month and up).
Sprint claims that it is to prevent spam..
## UPDATE OCT 10/10 ##
Looks like RBPro SMS might be coming back to the USA. I am working on adding EzTexting which is a US only solution (well US and Canada but Canadians are better staying with Clickatell) It will cost more and require you to jump through some hoops in the form of justifying you usage.
The plan now is to implement EzTexting in RBPro 2.0.
Clickatell.com will remain for non-US customers.
