Tata Docomo's network upgrade has made us one of India’s largest 3G/2G mobile operator with 1,84,000 sites, covering every nook and corner of the country. With this upgrade, we will be gradually phasing out our CDMA network so you will need to switch to our GSM network to enjoy our expanded network coverage or port to another service. To switch to Tata Docomo GSM, all you need to do is get yourself a GSM handset and walk into our nearest store to complete the migration in simple steps:
SMS PORT < Space > 10 Digit Mobile Number to 1900.
This code can be generated while roaming as well.
