The mobile service providers now have the greatest possible challenge ever – competing with the tariff. So do subscribers – choosing the best tariff and the widest coverage. Now both are possible with the help of dual SIM phones.
Recently MTS launched its operations in Karnataka. The tariff is so attractive that I shifted to a new technology – CDMA. But I now carry two phones – MTS for outgoing voice calls and Idea for SMS. This combination will help me get the money I invested on the new CDMA phone (which was 1.1k) in just 3 months.
Going forward, the best option is to buy handsets with multiple SIM support options. Karbonn KC555 is one good option, if you want dual GSM/GSM or GSM/CDMA option. Plan your tariff such that you can divide your STD, local and SMS between the two different networks and get the most out of money.
Another new challenge would be posed to the service providers when TRAI allows subscribers to retain the mobile number while switching the service providers. Many people stick to a service provider even though they may not be happy with the service for one reason – change of mobile number. This scenario is going to change very soon.
