No. The TSTT gateway is still down. Messages are being sent via an international gateway. Unfortunately, that gateway only supports Digicel and b-mobile GSM phones, so TDMA cells won't receive messages from this site.

You can integrate SMS into your system using one of our Application Programming Interfaces (APIs). directSMS have a number of APIs in the following technologies: Java, SOAP, HTTP and PHP. All our APIs come with supporting documentation and sample code. For further information, please check our developers page.

In general, a gateway is a program that allows systems using different data formats to connect to each other in as transparent a way as possible. In an SMS message gateway, one end of the gateway is connected to a mobile telephone network, over which SMS messages are sent. The other end of the gateway can be connected to different systems or services. These most commonly include mail systems and IP networks.

There are many applications that can use an SMS-to-IP gateway. Basically, the objective is to extend to the GSM network the functionality of client/server applications that currently run on IP networks, and to facilitate the access to various resources from mobile telephones that have the ability to send and receive short messages.

You will not be able to send/receive SMS messages if you are using a non-TSTT SIM. The TTCS page about GSM service in Trinidad and Tobago provides a list of coutries where TSTT GSM customers can roam and send/receive SMS messages.

If you plan to sell products or services on the Internet, you need to have an online payment gateway. A gateway transmits sales from your web site to your financial institution using a secure network. When a customer orders online, the transaction is sent encrypted from your shopping cart to the gateway, which then does the authorizing of the credit card information and returns the approval back to the site.

For Australian mobile numbers you must enter the destination mobile number in the standard 10-digit format, i.e. without a country prefix. For international numbers, you must enter the number in the international number format, i.e. the country code (preceded by a "+") and then the mobile number without the leading zero.

No problem, just send an e-mail to sms@pcmeasure.com. Examples are available for integration into various programming languages, so the process should not be time-consuming.

CIMD 1.3, CIMD 2.0, SMPP 3.4, UCP/EMI 4.0, SEMA SMS2000 OIS protocol for SMS centers over Radiopad and X.25 and several modems and mobile phones through AT protocol

a GSM device, Alamin supports GSM modems that understand the extended AT command set and support text mode for sending SMS messages (PDU mode isn't supported at present, but there are plans to implement it) or Nokia telephones supported by the Gnokii project (http://www.gnokii.org). Whichever GSM device you choose, you will need a connection cable to the serial port of the computer. If one isn't available, an infrared port in both the GSM device and computer is needed.

When the SMS gateway goes down, there's no notice of when it will be back up. It could be minutes, hours or even days. In rare instances, the gateway could be down for weeks. With over 15,000 messages being sent per day, that would mean queueing up all those messages and retrying delivery periodically until they can be delivered, or until it expires (after 4 days). This would be a huge toll on bandwidth, storage space, and CPU time.

Then modify your notificationCommands.

Of course. Authorize.Net offers an add-on module for transmitting check payment information. Contact us for more information.
