How to call 10086? It doesn't exist, and I can't send text messages.

1. Check the signal strength indicator on the display and the map of the network operation area. If the signal is weak, move to an open position, if in a building, move to a nearby window.

2. Check whether the network selection settings are correct. Try to manually select or try another network.

3. Check whether restricted calls are displayed. Check the call barring, fixed dial and closed user group settings (if any).

4, whether to reach the upper limit of the phone bill, query the phone bill.

5. If it still doesn't work, please reset the upper limit with PIN2 code or contact your service provider.
