"It just works..which is exactly what we were looking for! We've had thousands of phone numbers needing quality validation every day to ensure we were sending our clients SMS messages in the most efficient manner. Leveraging the Data247 API set was a breeze and we've seen outstanding, consistent results. We've saved substantial dollars by avoiding sending messages to invalid numbers."
O ur Text@ service doesn't send text messages but provides businesses with phone data that facilitates the sending of text messages to their customers. It does this by retrieving Email to SMS and Email to MMS gateway addresses of client's wireless phones. Businesses then use these addresses to send SMS and/or MMS messages to their clients via regular email.
Just like all Data247 services, Text@ service provides multiple ways to look-up phone numbers; real-time API, XML, batch file uploads, FTP server, Browser extensions, and manual data entry.

No, we provide you with the SMS and MMS Gateway email addresses so that you can send the messages yourself.
The maximum SMS length is 160 characters. MMS messages can be much larger.
While most people realize they can send text messages via a carrier's email gateway, most don't realize that they can send multimedia messages as well. Many carriers have two separate email domains; one for SMS and one for MMS. Others use the same email domain for both. 
Sending MMS has several advantages. First, the character-count limits which exist for SMS messages (which vary by carrier) don't exist for mms messages. Second, you can attach pictures or sound files to your email messages (the same way you'd attach them when sending to regular email addresses), and your customers will be able to receive them along with your text message. 
Note that different carriers have different requirements for pictures, and if a picture doesn't meet the criteria, it won't get displayed. We've found that making your jpg file as small as possible is important (Linux users: convert -quality 2 inputfile outputfile). Also, we've found that 320x240 pixels seems to work well for most carriers.
                                                  
Text messages sent to wireless phones via email (SMTP) are covered by the Can-Spam act of 2003. This act prohibits sending unwanted commercial email messages to wireless devices without prior permission. The second link below offers a really great explanation, including a good description of what constitutes a commercial message:
                                                  Stop Unwanted Robocalls and Texts
                                                  CAN-SPAM Act: A Compliance Guide for Business
                                                  
The free services (and many of the pay services as well) don't take number portability into account. As a result, when a subscriber for carrier A decides to change to carrier B and keep their same number, most services won't know about the change. For USA numbers, our services will be aware of the carrier change almost instantly.
We've found that when people aren't receiving text messages, it's usually because the phone carriers are blocking them. Unfortunately, each carrier has it's own set of criteria for determining which messages are SPAM and which are not. But usually it's because of one of the following:
                                                  1. Message content - it's possible that certain words in the message are raising flags, and are making the carrier mark the message as SPAM.
                                                  2. Messages sent per hour - If a large number of messages are being sent out at once, this could also raise red flags. If you have a lot of messages to be delivered which are not time-sensitive, it's best to throttle the sending of them as much as possible.
                                                  3. IP address - Sometimes the IP address that is sending the message can be blocked by some carriers. For Data247's Text@ service, the IP address doesn't matter because you're sending the message via email.
                                                  4. Email address - Carriers may block an email address, or an entire web domain if they believe SPAM messages are coming from them. If you're using a business email account (as opposed to a free Yahoo or Gmail account), there are things you can do to increase your email's reputation. Here's a link to an article which may be helpful for this:
                                                  How to improve domain reputation for better email deliverability
                                                  If you are using a free email account, you may want to try using a different one, or switching to a business email account and following the suggestions in the above article.
                                                  
No, we don't offer any guarantee. But, we get the carrier-lookup information from the carriers, so the carrier data should be extremely accurate and up-to-date.
                                                  As for the SMS and MMS Gateway Addresses, we do our best to keep these up to date. However, there are some carriers we do not have the information for. In fact, a few of the smaller carriers don't even offer email-to-SMS/MMS Gateway Addresses.
