If your telecom operator is unwilling to charge for only one thing either data or calls, you must port away to the fair one.
Internet paves the way to monopolize perfectly. User-friendly disruptive competition is the right way of doing that. Advertising-oriented coercive corporates making any nexus to monopolize any business for not competing in the user-friendly manner is the worst thing they do to the people of any country.
Incumbent telecom operators in India and some other countries, are trying hard for not allowing internet telephony to succeed so that they can continue with their sub-standard ways of plundering people of their money in the name of internet data packs. Instead of competing well with the emergence of Jio, they actually try to prevent all modern benefits to people such as the ability to make calls over Wi-Fi, 90 per cent cheaper international calling, HD voice, and innovations like simultaneous data transmission, video calls, and much more for their coercive corporate interests. A few suppressing states also behave like that but the government of India refrained from entertaining their irrelevant rhetoric.
Mobile data matters most through the smartphone stage of internet age. Calling usage can comparatively be left behind increasing data usage with the internet of things. If your telecom operator is unwilling to charge for only one thing either data or calls, you must port away to the fair one. That is a way users may disallow telecom operators for unfair charging. This may work along with the governments becoming legally vigilant to not let them make any nexus for not competing hard.
