My mobile phone has no card. What software should I download to make a phone call?

Hello, I'm glad to answer your question. You can download a WeChat. As long as you have WiFi WeChat, you can make voice calls. I hope it helps you, but the next card is better. It's more convenient, because many software registrations now need to provide your mobile phone number. "Super SIM card" has three advantages.

First, the combination of software and hardware. In the past, the mobile "SIM" was only the user's identity sign, and the KB-level data storage was equivalent to the "key" of the service. However, the "super SIM card" combines software and hardware, has NFC function (unlimited short-distance connection), and becomes a traffic card and car key, and the mobile phone can still be used with zero power.

Second, it is safe. In the past, security issues were mainly account numbers and passwords, and mobile phones could provide verification codes through SMS to achieve the effect of cross-verification. However, the existence of cloud services and "pseudo base stations" makes the cross service of short messages unsafe. The "super SIM card" has stronger user identification ability and is directly bound to the user's APP!

Third, low cost and high efficiency. Now is the era of electronic information, all kinds of electronic products can be seen everywhere, especially electronic authentication cards such as access cards and meal cards. There are tens of thousands of domestic users, and the cost is extremely high, and the decision-making cost of users is also very high, which will waste a lot of time; "Super SIM card" plays the role of resource integration, which not only reduces the cost, but also improves the efficiency.

Mobile phones are the era of everything.

At present, the mobile "super SIM card" has been released. Although there is still a period of promotion, the three advantages have already made users feel excited. The 5G era is the era of the Internet of Everything, and various mobile smart gadgets will appear in life. If the mobile phone uses the "super SIM card", it will open the era when the mobile phone is everything.

Smart phones are undoubtedly the "king" of mobile smart devices. Mobile has added fuel to the flames and launched a "super SIM card", which has a unique vision! 5G is the wave of technology in the future. Under the tide, many companies will be frustrated, and many companies will ride the wind and waves. Mobile company's "super SIM card" may make operators make a comeback! China Mobile's 4G network is relatively the fastest, and it can be used all over the world, but it is easy to be harassed by fraudulent short messages, with few packages, high fees and average network speed. ... for reference only
