Dual SIM Dual Standby Problem 20, Dual SIM Dual Standby Issue

There can be no such thing as generating memories.

Your old phone, good with wifi.

The new phone is not good with wifi.

There is an easy way to tell. Isn't the new phone bad.

You put the Unicom card and the mobile card, on the old and new mobile phones, and switch them. If you still use a new mobile phone, it is not good to use wifi.

It can basically be judged that the function of the new mobile phone to connect to wifi is not good.

Or in addition, you can next the testing software to see if the wifi function is good?

My guess is,Your mobile phone may be a customized version of Unicom,It is limited to 3G or 2G with other networks,The speed naturally can't go up。 Your broadband is mobile or telecom.

As a practitioner in the mobile phone industry, I usually come into contact with a lot of mobile phone products, and I often carry a few mobile phones in my bag. But when it's not necessary for work, I still prefer to use only one phone for the following reasons:

1. Now the vast majority of mobile phones are dual-SIM dual-standby, although I have three or four mobile phone numbers, but the commonly used ones are only two, and a dual-SIM dual-standby mobile phone is enough. And most of the flagship mobile phones this year are true full Netcom, that is to say, two mobile phone cards can switch traffic at any time to go online, as a main user of telecom numbers, this year's full Netcom mobile phone really brings a lot of convenience. If there is no traffic on one card, just set it up and switch to another card, so you don't have to worry about the telecom number having no signal after changing to the supplementary card as before.

2. Nowadays, many dual-SIM dual-standby mobile phones have the characteristics of large screens and large batteries, and some mobile phones even have built-in 5000mAh batteries, so that even if two cards are inserted and used at the same time, there is no need to worry about battery life. And if you use two mobile phones, you usually have to pay attention to charging the two mobile phones, which is more troublesome.

3. The problem brought by large-screen mobile phones is that they are inconvenient to carry, especially in summer, if men go out without a backpack, they can only put the mobile phone in their pants pocket. If you carry two mobile phones with you, you won't have a place to put your wallet, keys, or anything. Even if you carry a bag with you, it is quite inconvenient to put your mobile phone in your bag to receive calls**.

This should be a new phone problem, why not swap the phone card? Generally, it will not be the reason for the SIM card. Swap the SIM card and you'll know what the problem is.

In addition to copycat machines, domestic brand machine radiation and other indicators are controlled within the allowable range, and Lenovo brands are recommended.

Dear, I'm glad to answer for you Answer source: The disadvantages of double SIM double stupidity are as follows: First of all, its first disadvantage is that it consumes too much electricity.

Since the dual-SIM dual-standby mobile phone needs to run the functions of two mobile phones at the same time, the power consumption is very large, and the general dual-SIM dual-standby mobile phone is very power-consuming. The second is that the dual-SIM dual-standby hand-sharing is easy to confuse the two cards when using them, resulting in various errors.

<> introduction: 1. This type of mobile phone will generally set a main card and a secondary card by default;

2. When you hit **, there will be two dialing number keys, which represent two card dials;

3. When sending a text message, after answering the text message, there are two send buttons, corresponding to two cards;

4. The main card is generally used by default, and if you need a supplementary card to access the Internet, you need to switch to the dual SIM management in the settings.

Note: Phones that support Dual SIM can use two cards at the same time.

The main card of the mobile phone has two meanings:

One is that a number is divided into two cards, but the supplementary card can only be used for data services such as Internet access, and SMS and ** are not available;

The first hand mountain stupid species is a**inside, there are two different numbers, and the two numbers share this**.

When the primary cardholder selects the base**, the additional cardholder can share the voice, SMS, MMS, data traffic, Wi-Fi duration, pre-deposited credit refund or free credit and other benefits in the primary card's base**.

Dual SIM dual standby, in layman's terms, is two SIM cards standby at the same time, can be connected at the same time without interfering with each other, the existence of dual SIM dual standby mobile phones always reflects its practical side.

There are two types of dual-SIM dual-standby phones:"Dual SIM single pass"and "Dual SIM Dual Pass".

1.What is a "one-pass".

Generally speaking, a mobile phone can answer the incoming calls and received messages of two mobile phone cards, but it cannot answer two mobile phone cards at the same time. What we now call Dual SIM Dual Standby is actually the meaning of "Dual SIM Single Pass".

2.What is "Dual Pass"?

Dual SIM dual pass refers to a mobile phone, that is, when you pick up ** there is another card at the same time ** also comes, then you can also pick up another mobile phone card **, this is called double pass, if you can't connect it, it is not double pass, but it is still double standby.

What is the difference between dual SIM and dual card?

It can only achieve dual SIM standby at the same time, not simultaneous calling, which is the so-called "single pass", which is not the actual sense of dual SIM dual standby. When a dual-SIM dual-pass mobile phone is on a call at one number, there will be a prompt when another number has ** coming in, and the user decides whether to answer it.

Dual-SIM dual-standby technology was officially applied to mobile phones in 2005, Yulong Coolpad launched the world's first dual-SIM dual-standby mobile phone Coolpad 728, so far the company that has most of China's dual-SIM dual-standby technology patents is China Unicom and Yulong Coolpad, of which Yulong Coolpad's dual-SIM dual-standby technology is the most mature, most of its mobile phones are using dual-SIM dual-standby dual-network dual-pass technology.

Mobile phone can insert two mobile phone cards and can be on standby at the same time.

Dual SIM dual standby, that is, a mobile phone can be on two SIM cards, that is, there are two good numbers, and the two numbers can be in standby mode at the same time, that is, they are all turned on, and you can receive any call.

It's that mobile phone supports two SIM cards at the same time, and both cards are standby at the same time, and they can be entered**.

The real dual-SIM dual standby is possible, such as Yulong Coolpad's. The others are all on standby together, and it depends on the phone whether they can be answered at the same time. It's okay to punch in.
