Red rice mobile phone has a signal to send text messages, but it can't make phone calls or surf the Internet.

First, the common reasons why mobile phones can't answer the phone and their solutions are as follows:

[1] Check whether the mobile phone is in arrears, and suggest to pay for recharging;

[2] Check whether the mobile phone is set with call forwarding, flight mode on and call barring. Suggest canceling and try again;

[3] Check whether the function or signal of the mobile phone is normal, and suggest to change the mobile phone or try again;

[4] If roaming to other places can't be used, it is recommended to check whether the local network signal is normal and whether roaming permission is enabled for this number;

[5] Try to restart or change the phone to see if you can answer the phone;

[6] Take the mobile phone card to the local business hall for testing or replacement.

2. If your mobile phone can't surf the Internet normally, please check the following:

1. If you don't restart your phone after upgrading to the 4G package, you won't be able to use the Internet function normally.

2. Confirm whether there is a network. I suggest you use it in a place with strong signal.

3. Check whether there is any phone bill in the account. If the balance is insufficient, it needs to be recharged before it can be used;

4, can be turned off for 3-5 minutes, restart the phone and try again;

5. Check whether the USIM card is inserted. If it's plugged in and still doesn't work, I suggest you go to the business hall to check whether the USIM card is faulty or not.

6. If the traffic reaches the peak in that month, the network will automatically shut down. We suggest you pay attention to our SMS reminder or inquire about the package product description.
