Though internet companies want people to use smartphones and apps, the fact is that smartphones are not very reliable
For example the Itel A25 purchased more than one year ago cannot be used since it is difficult to unlock it.
It appears that a wifi network is used to hack the smartphone and prevent unlocking
Since the phone cannot be unlocked, all the features are wasted
Additionally the mobile phone connection costing Rs 479 for 28 days is also getting wasted
So the domain investor is forced to purchase a new smartphone, spending more money
Since the smartphone was mainly used for mobile internet , switching smartphones will not require much change, if apps were installed it will create more problems.
