I have been MTS wireless datacard from last 2 to 3 years.Its a good connection if you are travelling a lot and need a good internet connection on the way.I have been travelling from Mumbai to Kolkata and delhi, I have never faced an issue on this connection.It works good in fairly all the cities. I have been using mts mblaze postpaid. comparing to prepaid plans, postpaid gives better plans. Mblaze comes with 3G plus connectivity with faster and smoother internet surfing and downloadings. comparing to its device price it delivers good value for money and features like wifi connectivity etc.comparing to its plans price, MTS provides more data allowance than other ISPs with minimum amount.The only problem with mts is the availability of networks.In some areas it is very difficulty to access the networks.but the company has been resolving the issue by spreading their networks.
