Shock laga kaya? This was really a shock for me, because I recently purchased a LYF mobile exclusively for my data usage purpose. In that time the retailer, jio office and jio customer care executive assured  me that I will get a PREVIEW offer for 90days. Also I checked in MyJio app and confirmed, In that It was clearly mentioned that FREE UNLIMITED usage will be provide till Novrmber 27 2016. Now reliance showed their true color,

I am already on Jio Preview Offer, what is the impact on my plan? Will I not get the unlimited offer any more?

If you are an existing Jio Preview Offer customer, you will be automatically migrated to the Jio Welcome Offer on 05th Sept, 2016. As a part of this Offer, you will continue to enjoy unlimited HD voice & video calling, unlimited SMS, high-speed data and access to a host of Jio premium apps till 31st Dec, 2016.

4GB daily limit will not be burden for many users but for heavy users like me its quite embarrassing more over  THEY CHANGED their WORD. They assured that preview offer is for 90 days but they deviated from their statement
