LG- Inspur can't send short messages.

There is an information security center number in the short message function of the mobile phone. This number is provided by the operator (the mobile card is provided by the mobile company ... Unicom card is Unicom).

You can call customer service and change it ... I don't know your mobile phone. I use the smartphone Nokia N97.

If you have a smart phone, it may be that downloading the software caused the virus, so you can format all the phones, provided that you back up all the important things!
