You have been receiving SMS codes: TA-ICICI, AX-Airtel…and wondering what’s it?

Recently, from almost a month SMSs from Banks, Service Providers, Companies have started prefixing something like ID, AT, VK…etc. What’s all this after all!!? Here I am to explain you what it is! Normally these SMSs originates from a Bulk SMS provider where you can use 11 digit Alpha-Numeric characters as "Sender". But there were some security risks in this method. I was able to give a phone number as "Sender" & it appears as that person at the recipient end. Basically there was a chance to send SMSs as a different person! I was actually using this to fool my friends.

But the new TRAI regulation insisted bulk SMS providers to restrict the "Sender ID" to 8 characters. Other three characters should be used to specify who is the service provider & where it’s originated from. Say for example: HDFCBANK sends an SMS to you using bulk SMS provider located at Tamil Nadu which uses Airtel. You will receive it as AT-HDFCBANK. First character specifies which service provider the message is being originated & the second character specifies from which location it’s originated. Here is the table which has details of these SMS codes:

Service Provider Codes:

So, combination of these two constitutes the first two digit of ?Sender? followed by an hyphen (-) & actual sender name.

Tata indicom recently launched Blackberry service, I was curious about what they have to offer. I come across an awsome UNLIMITED tariff plan exclusively for Blackberry users. The plan is called as Platinum 2500 & details are as below:

So you get unlimited local & STD calls, unlimited SMS & also unlimited data usage (internet) for Rs.2500 a month. This is the only ALL UNLIMITED plan which I ever come across & right choice for businessman. Looking forward for similar plan from any GSM service provider like Airtel or Vodafone.

I never thought Tata Indicom is providing such a great service. If you buy any wap enabled handset from Tata Indicom, it comes with wap connection instantly! I had checked in my cousin’s mobile (Haier 1200) it was providing access to all wap sites. As I checked, there were no usage or airtime charges. They may charge you only when you download any content from their wap portal (am not sure). Many stuffs explained in this site can be done with this connection (ex: gmail ).
