What if Apple 5s can't send text messages? How to deal with

IPhone5s can't send SMS: SMS function is not activated, which may be due to lack of Internet access or mobile phone arrears.

Specific operation steps:

The first step is to check the center number.

Enter "*#5005*7672#" in the dial, and click "Call" to see the SMS center number set by iPhone5.

Step 2: Set the number of the SMS center.

Enter "*5005*7672* SMS Center Number #" in the "Dialing Keyboard" and click "Call" to complete the setting of SMS Center Number (for example, Shenzhen Mobile * 5005 * 7672 *+861380075500 #).

Just restart after setting, remember to add +86 before the SMS center number.

In addition to the powerful 64-bit A7 processor, the iPhone 5s released in the early hours of September 1 1 and 20 13 has been greatly improved. IPhone5S supports touch ID on the Home button, and the sensor is built in the Home button.

With the patented technology of TruePrint, AuthenTec products can read the active layer under the skin surface (where people's fingerprints are really located) and realize extremely accurate and reliable fingerprint imaging. This subcutaneous reading mode enables AuthenTec sensor to cope with common skin surface conditions and truly read all fingerprints anytime and anywhere. Through TruePrint, AuthenTec produces the smallest sensor on the market, but its security, privacy and convenience are not inferior to larger sensors.

Touch ID needs to be completed by the Home button, and its sensor is built in the Home button. Next to the home button (it becomes flat instead of concave like the previous Home button) is a stainless steel sensing ring, which can be sensed when the user's finger approaches, and the sapphire layer on the surface of the Home button will act as a lens, so the user can let the mobile phone sense the presence of the finger without actually pressing the button.

The thickness of the touch ID is 170 micron, which can detect 500ppi images in real time. Apple officials even said that it can scan 360 degrees in all directions, which can ensure the recognition of different directions, and because the touch id allows you to add multiple fingerprints, it also knows the people you trust. Fingerprint data is stored in a special location on the A7 processor. All programs have no permission, and will not be uploaded to the network, nor will they be backed up with Apple ID. Only the touch ID can call the data inside, thus ensuring security.

IPhone5S fingerprint recognition function Simply put, fingerprint recognition is only a security function, and the Home button is still the original Home button, which can also be pressed for operation. The difference is that fingerprint identification can now be realized on the Home button, which makes it easier and faster to authorize related operations. As for the actual use, it is to unlock and change the system password. However, because Apple will not open this function to third-party developers at present, it ensures security, but it also greatly limits the scalability of fingerprint identification.

Apple iPhone5S continues the classic design of iPhone5, but in order to differentiate itself, Apple added a gold version this time, and also provided a dark gray and silver version (except the previous black version). On the screen side, the Apple iPhone5S is equipped with a 4-inch screen with a resolution of 1 136*640 pixels and a ppi of 326. In terms of body size, the iPhone5S is 123.8*58.6*7.6 mm and its weight is 1 12 g, which is basically the same as the previous iPhone5.
