I have a mobile card on my mobile phone, so I can make phone calls and surf the Internet, but short messages are always delayed, especially for telecom users. What is the reason? Urgent! ! Ask a master for advice The networks of these companies are different. China Mobile and China Unicom are GSM networks, and telecommunications are CDMA networks. Of course it will be a little different. As for the delay of SMS, it's usually your mobile phone. The telecommunications bureau will not delay your SMS platform for no reason. Try another mobile phone. If it is still slow, call 10086 to see if you can recover the data. Hanging q on the internet with a mobile phone may also happen.
