Why doesn't the tablet have a phone function? The phone function I'm talking about is: Answer+Call+SMS.

I thought the same thing as you, but later I learned some information, which was far from what you thought.

1, the tablet seems to have added a call function module, which costs little, but in fact, if this product wants to go public, it has to apply for a network access license. For example, any licensed mobile phone you buy has a network access license attached to the back shell, which is difficult to do.

2. There are some shanzhai 5-7 inch tablets on the market where you can make phone calls. These tablets can indeed make phone calls and even support 3G video calls, but in fact, the call quality and stability are very poor. There are two reasons for this. First, shanzhai tablets are cheap chip solutions. First, the product hardware design is flawed, but the cottage manufacturers have no time, energy, funds and manpower to do the testing and quality management work slowly. Then come back. So can those dealers sell this kind of thing without headaches? If the dealer doesn't want to sell it, what's the point of your production?

3. For fun, many basin friends generally hope to make a phone call+smart tablet+cheap, especially the price must be cheap (there are many choices that are not cheap), and basically don't mind "radiating" this thing. In fact, domestic 3G tablet computers basically have serious radiation exceeding the standard ... Omit the figures and don't say much. What else is safe for us?
