Reliance Jio may still be far away from starting its commercial operations, but the company has already made its presence felt in the market. Before the nationwide roll out takes place, Reliance Jio wants to optimize its network, and to do so, it has already come up with 4G Preview Offer where customers using 4G-enabled Samsung or LG can get the Jio SIM card and use all its services for free for 90 days. Now, multiple reports are indicating that the preview offer has been opened to everyone. As a part of the package, Reliance Jio has also bundled offering unlimited HD voice calls, unlimited high-speed internet access and downloads and an unlimited access to Jio app ecosystem for 90 days.

Multiple reports suggest that some Reliance Digital stores are offering Jio 4G SIM cards to any customer using a 4G smartphone. While Samsung and LG users will have to download the MyJio app and generate the code, other smartphone users can just walk in to the store, submit documents and get the Jio SIM card. The only catch is you still need to install all the Jio apps on your smartphone, so it would be better if you install them from here on your Android smartphone before reaching the store. It would also make sense to call your nearest Reliance Digital store before landing up there since many have not received any update from Reliance Jio about the offer being opened up to everyone. We contacted some Reliance Digital stores in Mumbai and they said that they haven t received any such update, yet. We have also reached out to Reliance Jio, and waiting for confirmation. In case the Reliance Digital Store in your city hasn’t received any update, these are the other ways you can get a new Jio connection along with preview offer.

Reliance Jio is trying to differentiate itself from other operators by focusing on three key areas — VoLTE HD voice calling, high speed data and content services. The company has already rolled out its app ecosystem — available across Android and iOS platforms. Let s take a quick look at these apps and what they do.

MyJio: This is the core app where you can find all details about your account such as your tariff plan, account balance, data consumption, recharge, profile, and more.

JioJoin: The app works in conjunction with the JioFi 2 or your Jio SIM card — allowing you to make HD voice calls, even from a non-VoLTE supported smartphone. As of now, the app is only available for Android, since all of the iPhones on sale now are LTE enabled. You can also send and receive text messages and chat with other Jio users with stickers, emojis, send files and more.

JioBeats: It is a music streaming app just like Hungama Music, Gaana, Saavan and Apple Music. The service has a collection of 2.5 million HD songs in 20 different languages including Hindi, Gujarati, Bengali, Tamil, Telugu, Bhojpuri and more. In terms of genre, you can choose from Gazals, Jazz, Hiphop, Party, Rock and more.

JioOnDemand: The app lets you watch OnDemand movies, just like Netflix, BigFlix, Google Play Movies and other services. It also includes popular TV shows such as Tarak Mehta Ka Ulta Chashma, CID, The Kapil Sharma Show, Aadalt and more.

JioPlay: It is a live TV steaming service that lets you catch all the live TV shows on the go.

JioSecurity: Android being an open source platform, it is also highly prone to a large number of viruses and vulnerabilities. We recently came across QuadRooter vulnerability that allowed hackers to take control of Android smartphone by gaining root access. Powered by Norton, JioSecurity app aims to keep your Android smartphone save from such attacks.

JioChat: Just like WhatsApp, WeChat, Hike Messenger and others, the JioChat is an instant messaging app. The app let you make voice and video calls, and chat with users. You can also send stickers, doodle, share files and do a lot more using the JioChat Messenger app.

JioMoney: The JioMoney app, as the name suggests, is a digital wallet that lets you pay for different services such as landline and electricity bills, mobile and DTH recharge, send money to recipients and more. You can also pay at participating merchants without having to carry your credit or debit cards. We did try out the app and here are our initial impressions.

JioDrive: The app is a one stop shop to all your data storage, backup and recovery needs. JioDrive users get 5GB of cloud storage space to backup photos, videos, contacts, SMS and more. The best part about the service is that you can also access it from multiple devices — including your smartphone, tablet, desktop PC or laptop.

JioMags: Reliance Jio has two apps JioMags and JioExpress News. While the JioMags lets you read all the popular magazines and comics, the JioExpress News app is similar to Flipboard and News Republic letting you read all the latest news from tech to sports, business, lifestyle, health and more from variety of online publishers across the globe.

Do Note: Access to Reliance Jio suite of apps is free and zero rated at the moment (which means, you are not charged for the data downloads). However, there is no word on the pricing after the end of preview offer. It is something that we will come to know after the commercial launch of Reliance Jio 4G LTE services takes place.
