Tata Docomo has launched a new data-only prepaid plan offering data benefit of 39.2GB of 3G data for 28 days under Rs 100. This prepaid plan from Docomo competes with the Rs 98 Data Tsunami plan from the state-run telco BSNL. Having said that, this plan from Docomo doesn't offer any voice or SMS benefits, instead, it's a data-only plan. Notably, it's 3G data benefit as Docomo is offering services under Intra Circle Roaming agreement with Bharti Airtel. Technically, users will be able to enjoy 3G data benefit under Airtel's network. BSNL is providing 1.5GB data per day with its Data Tsunami plan, while other telcos such as Jio, Airtel, Vodafone and Idea Cellular doesn't have any such plans under Rs 100.
Tata Docomo clearly states that this plan is not intended for commercial use and data roaming facility is applicable only on TTL own sites, in other networks, it will be charged as per the base tariff plan. Also, do make a note that post the usage of 1.4GB per day, 10 paise per MB will be charged.
BSNL, with its newly launched Data Tsunami plan, is offering 1.5GB data per day for a period of 26 days and the Rs 99 plan from Docomo is valid for 28 days. Even though the daily data benefit is lower on Docomo network, it managed to match BSNL with two-days more validity. Sadly, both the telcos are not offering any voice calling or SMS benefits with these plans.
Other telecom operators such as Reliance Jio and Bharti Airtel also has similarly priced prepaid plans, but they're combo plans, not just data plans like Tata Docomo and BSNL. Airtel has a Rs 99 prepaid plan with which it's giving unlimited voice calls without any limit, 2GB of data and 100 SMS per day for 28 days, while Jio has an open market Rs 98 plan offering similar benefits of 2GB of 4G data, 300 SMS and unlimited voice calls for 28 days.
