Unicom network, Huawei P8QQ always can't send information. What should I do?

If WeChat or QQ group chat can't be sent, it is generally related to the signal. If the signal at that location is not very stable at that time, it may not be able to send or receive it in a short time. Please try again another time. If it appears frequently, change your location or change your mobile phone. If the location is used normally, it may be a signal problem of the location, so you can contact the local customer service for feedback. If there is no problem with changing the phone, it may be the original phone. You can check the settings or change your mobile phone.
