Calling and texting are very delayed and consume a lot of electricity.

RT, it's normal to answer text messages and make phone calls. It's definitely not the phone. During the trial, three mobile phones were changed, one of which was newly bought. SIM card is also new, but there will still be a delay in sending information, not every time, but this phenomenon will occur after sending two or three cards. I called 10086 and asked, saying that the short message function was reopened, but the problem remained after the opening. The platform number of the SMS receiving center is also correct. Now there is really no way, send a text message to confirm several times before sending it! Can someone help solve it and explain it! ! ! ! !
