The demand of iPhone users for dual cards has never been reduced. It is too cumbersome to take two phones with them, and it is also troublesome to charge. I used to take two mobile phones out with me every day, but it was inconvenient after all. Finally, I had to leave the number I used frequently at home. Sometimes it was inconvenient to log in an account with a backup phone and need a verification code. Don't ask me why I keep more than one number. Every dual card user has a reason to have to use dual cards. Sometimes another number is reserved only for someone or a memory.

This product I was lucky to try hit my pain point completely. It is an iPhone 6s protective case integrated with communication chip, battery, Bluetooth, independent earpiece and microphone. Except for Apple, this protective case basically has the hardware of a functional phone. Simple white packaging.

The hardware supports Bluetooth 4.0, the GSM network of China Unicom and China Mobile, but not the CDMA network of China Telecom. It only supports calls and SMS, but not data connection. It perfectly supports 6 and 6s. The battery capacity of the back clip is mAh500. It can be used for one day in standby mode. Of course, there are few secondary card phones.

The Sim card slot is a Micro Sim card. If the Nano card needs a card holder, it is attached with a tape.

The family photo is a Nano card holder, manual, and two in one data cable, which can charge the mobile phone and the protective case at the same time.

Compared with ordinary protective case K2, it is a little thicker, but it is far less thick than expected. It is still very thin on the whole. The side is relatively more rounded. In addition, the smooth material feels more or less smooth.

The slot below the camera is the earpiece of the phone case, so if you use the phone case directly to answer the phone, the back of the phone case is close to your ear, which is a little strange, and the sound quality of the earpiece is still available. However, when you use the phone case directly to talk, the other party can often hear the stress of their own speech, So I usually use Bluetooth to return calls with my phone's APP to ensure the quality of calls.

After half a month of use, there have been many places with obvious wear on the shell. It is suggested that the next generation of products can use frosted materials. The sturdy appearance will attract more male users. After all, the target user should be a restless digital home.

It is very harmonious to use my own dual port mobile power supply and two interfaces to charge at the same time without fighting. It is also very convenient to use the built-in dual head charging, so it is more convenient to charge two devices at the same time.

The supporting APP is called IKOS, and the operation interaction is very simple. The power in the upper right corner is not the power of the phone, but the power of the back clip. The operator in the upper right corner is the secondary card of the back clip.

At present, the most perfect function after half a month of use is the dial-up experience, but the experience of answering the phone is not perfect. My iOS 10 6S can't answer the phone at the APP end. Calls can only use the answer key of the back clip and the independent earpiece and microphone of the back clip, and the sound of the back clip itself is too small to hear the electronic sound of DidDidi, Fortunately, missed calls will be displayed in the message.

SMS support is also very perfect, sending and receiving are very fast.

summary

advantage:

1. Portable and light;

2. Independent microphone and earpiece, you can answer the phone even without connecting the mobile phone;

3. Complete APP functions

Shortcomings and suggestions:

1. The APP does not support answering calls well;

2. The phone case itself feels bad, too slippery and easy to wear;

In fact, it is no problem to make the phone case thicker, but the hand feel and appearance need to be more distinctive and textured. After all, as the phone case itself, the appearance is also very important.
