Why can't iphone6 send text messages?

If your mobile phone can't send short messages, you can try to restart or change your mobile phone to test whether there are any of the following situations:

1. SMS center number is not set correctly. Please re-enter the correct SMS center number.

2. There is no signal or the battery of the mobile phone is insufficient;

3. The system is busy during the peak period of holiday SMS sending. It is suggested that you try again later or avoid the peak period of sending.

4. The sending format is incorrect.

5. The short message sending time exceeds 24 hours;

6. The mobile phone shields the short message sending function;

7. Blacklisted by SMS;

8. Insufficient quantity balance;

9.SMS inbox and outbox are full.

If the above reasons cannot be solved, you can contact the local manual customer service or go to the business hall to confirm whether the SMS function is enabled and hand it over to the staff.

Introduction:

Short Message Service (SMS for short) refers to the text or digital information directly sent or received by users through mobile phones or other telecommunication terminals. The number of characters that users can send and receive SMS at a time is 160 English or numeric characters or 70 Chinese characters.

In 20 14, China Mobile announced that it would create a new service entrance for users in the era of mobile internet through "unified communication". This move is interpreted by the industry as: giving up SMS and embracing unified communication.

China Mobile's "New SMS" will be charged according to traffic. As part of the unified communication service planning, informed sources revealed that the service is expected to be unveiled in the middle and late February this year and is expected to be commercialized before the end of 20 15.

Advantages:

First, the transmission channels are smooth.

At present, gateways and cards can also be used for short message group sending, but the arrival rate of sending is not as good as that of short message group sending platform. The reason is that the SMS sending platform has many sending channels and high sending arrival rate.

Second, the operation is simple.

The short message group sending platform used in the network background can independently write relevant text content according to the needs of the sender, which is simple to operate and convenient to modify. At the same time, unified transmission also ensures the accuracy of information.

Disadvantages:

First, the information capacity is small, which is less attractive to people.

Short message platform is boring because it can only be edited by words and lacks corresponding picture material. Moreover, with the proliferation of short message advertisements, the reading rate is not necessarily too high. The sending cost of MMS is too high.

Second, it is difficult to collect terminal data.

SMS platform needs corresponding numbers to send, and how to collect these numbers and how to send them to those customers after collection has become a very important issue, so the customer coverage of SMS platform is not necessarily comprehensive.

Third, the number and time of sending are limited.

Generally, the number of SMS platforms is limited, thousands or even tens of thousands. It is basically impossible to send messages after 8 pm, and its flexibility and management are not as good as that of SMS power grid.
