The Decline Of Local Mobile Shops in India ( Rise of Online Mobile Phone Shopping)

The Online Shopping Market has already becoming a fat guy gradually. But the latest trend created by Xiaomi , a leading Chinese brand in last few weeks has made a huge threat not only to the leading smartphone manufacturers but also the Local Mobile Phone retailers.

Indian consumers are rapidly moving to the Smartphone technology. Leading manufacturers from various countries all over the world realized this phenomenon and laid their foot in Indian mobile phone market.



Nokia's era is already came to end as they refused to switch over Android technology . Nokia's Market is gradually acquired by Samsung by introducing variety of Smartphone variants.

Side by side some other companies like Micromax, Xolo, LG are also developing their brand images in Smartphone market.

decline of local mobile shops

But, the sudden Entry of Xiaomi with their Unique marketing strategy has created a huge threat to the leaders running in the race. Xiaomi has sold about 1 Lakh unit of Mi3 in 5 weeks and 40000 units of Redmi 1S in 1 week . They sold in "Flipkart Only" Strategy.

Apart from this , the major segment going to be affected by their strategy is Local Mobile Phone Retailers.
In recent Interview , Xiaomi official reported that 20 to 30 percent of mobile phone price has to be given to local retailers as Commission.

But if they sell their product directly in their website or Flipkart, customers can be get benefit as they do not cost the commission cost from the customer.

This will lead to a big decline of the local retail shop segments and this can be compared to the decline of local town cinema theaters at the time of rise of Television Era.

Likewise , when online recharge system introduce, the local recharge card business has almost disappeared.
Rise of Mobile phones lead to the decline of Local Public PCO phone centers.

Now, it is the time that comes to Local Mobile retailers. Unless , they make a alternate strategy there is less chance to survive against the online shopping.


Android Phone: To change SIM 2 slot into WCDMA 3G Signal in dual SIM smarphones

What is WCDMA sim slot : 

In Dual SIM smartphone, only one SIM slot can be activated with high speed internet or WCDMA means (Wideband Code Division Multiple Access) . In some smartphones, it is interchangeable. But in some smartphones, primary sim is WCDMA / GSM and secondary sim is only for GSM (low speed internet  connection like 2G, EDGE)

dual sim slot switch 3G android

If it is clearly provided that  SIM 1 Slot is for WCDMA and SIM 2 Slot is of GSM type, then this procedure will not work most probably.
The only solution is to swap (Change the sim cards between the slots and use your desired 3G sim card in Primary SIM 1 slot.

Mostly dual SIM phones with high end specifications has this 3G Switching option and phones in low entry level market doesn’t have this switching option and they have primary SIM as 3G and Secondary SIM as 2G

If you hope that your phone specification has both slots can be used as 3G then we can proceed further.
Here we have to note that at same time we can’t enable 3G in both SIM slots.



How to set sim2 as wcdma:

So, If you want to convert Sim 2 Slot into 3G, you have to set SIM 1 slot as GSM, then set SIM 2 slot as WCDMA or 3G
Likewise if you try to convert SIM 1 as 3G, set SIM 2 slot as GSM first and then enable WCDMA in SIM 1 Slot.

It is better to plan accordingly in which SIM card, you are going to browse high speed internet mostly, then FIX that simcard as a Primary SIM card Slot.

Changing it often may result in confusion and it may also result  in unnecessary loss of talk time.

Will GSM sim work in WCDMA slot ?

Yes, GSM sim will work in WCDMA slot. But the internet browsing speed will be according to 2G speed of the network provider

To change from 2g to 3g on a dual sim lenovo smart phone ?

  1. Go to Settings → Mobile networks
  2. In network type choose WCDMA or 3G only
  3. Now your phone will show H or H+ or 3G signal if it is available in your location.

Future Vision of Google's loon Project and Facebook's Internet.org Project

Internet Giants Google and Facebook have recently laid their foot prints in a grand vision . Yes they aim to spread the rays of Internet all around the world in nook and corner of the living habitats.



Google have started its journey in this project with its innovative loon's Project in which huge balloons will fly over the landscape in a height over than the path of Aero-planes. Those balloons will spread internet signals to the people who set up loon antenna. And there will be signal connection between these balloons itself.

Currently this project is in test phase in NewZealand  with selected number of peoples and Google often reports that they are learning and rectifying lot of things to improve the efficiency and reliability of the loon project.

Soon we can expect the project will be spread in other parts of the world.

Google loon project vs facebook internet org project

On the other hand , Facebook joined hand with huge corporate industries like Ericson, Airtel etc to increase the internet reach among peoples. Their main preference is to spread the internet throughout Africa where most of the nations are still developing and under developed. Internet facility may improve the lifestyle of the continent is the strong belief of Facebook. They have made the vision statement as Making the Internet Affordable

There is no doubt that providing affordable internet among ordinary people will help to develop their lifestyle, provide them the basic services. But critics has also passing comments that the Big brothers of Internet will make a  lot of profit in means of advertisement and there hides a huge selfishness behind the social responsibility.



Anyway, it is a welcoming activity that Facebook and Google jumped into this project, though governments of the countries resists to take such steps toward spreading technology.
