On the market, often flooded with a large number of dual sim phones, and many consumers just know that the phone can be inserted two cards, direct calls, and you really understand the meaning of it?

In fact, in addition to dual SIM, the market's mobile phone want is also flooded with a variety of double, here I will first to explain to you!

dual Card: As the name implies, two cards, broadly speaking can be inserted into two cards can be called dual-sim phone. But there are bugs, some phones have two sim slots, but only work one card at a time! This is in essence still capacity is! Cottage Phone long tricks!

Two SIM card slots may not be able to insert two cards at the same time work, remember to remember Oh!

Double : This is more than the dual sim, meaning is very simple, is that there are two cards can be at the same time standby to answer the phone! Double to be destined to have two card slot two card!

Dual mode: Two different modes of support, but we remember that many phones are two-mode, but dual-mode is not necessarily able to work at the same time, for example, millet Typical version, is capacity is dual-mode mobile phone

This is a common 2G and 3G 4G network format, casually support two, is dual-mode mobile phone!

There is only one SIM card slot that can be plugged into a telecom card or can be plugged into a mobile GSM card! This is called dual-mode capacity is mobile phone!

It is necessary to note that dual sim phones are not necessarily dual-mode mobile phones!

For example, this Mann ZUG 1 mobile phone, is can dual sim, but it only supports two GSM mobile phone card! Simply put, you have two mobile GSM cards, just plug it in!

Finally, of course, it is also the most critical, that is, of course, double-pass!

The so-called double-pass, is the dual sim on the basis of more advanced features!

Simply put, the conventional dual sim phone, although in the standby time, two mobile phone numbers can receive the phone, but when a number is connected, another number will not be able to enter, and you will be completely undetectable, so for some business users, it is more difficult! Some phones are not to be missed!

And this double pass is often the dealer most reluctant to tell consumers, you have heard, dual sim to single-pass the saying? Or do you have a channel, Multimode single-pass saying? Obviously not, but, as long as it's not a double pass. Once your phone is answered, the other number is automatically considered to be busy. The most abominable is that there are many users with more than 10 years of dual sim phone can be completely in the dark do not know, the original own so many phones have been missed!

This is my use of ZTE's N986 special production of a video, that is, when a telephone connection, another number also has a phone when the situation, we can not tell the students, you may own at home on their own mobile phone to do this test! Do not really answer the phone, as long as there is a call prompt on the qualified, nor charge!

All this is by the telecommunications company expensive tariff, the chaotic package force! To put it simply, the most common use of dual SIM double-mode double-pass is, the field of a number, a local number, avoid roaming fees! The roaming fee of the pit daddy! Call a number, answer the phone for a free number. Work a number, life a number! One number on the Internet, one number on the phone! In short, the advantages of dual SIM is indisputable! But the only disadvantage of dual SIM is that the model is too small, the configuration is too bad, the price is too expensive. I believe if you have searched the mobile phone, you should understand what I mean! In fact, like n986 such a model is really less and less ~~~~~~~

In fact, the dual-SIM dual-mode dual-pass in modern sense, in fact, based on the OFDM technology on the basis of software radio! Audio or the audio!? Just go in after the full digital DSP software to separate the spectrum! I believe the price will slowly come down!

This is my N986 mobile phone double shell set. Finally hope that more and more friends, can enjoy the dual SIM dual double-mode dual-pass mobile phone blessing! Also look forward to the transfer of the network to the early popularization of the business, I believe this is the true gospel of our mobile phone users!
