Why can’t my Sony Ericsson w580 phone send text messages?

Hello friend, there are only two situations for the situation you mentioned:

1. As mentioned above, it may be the short message setting of your mobile phone. The "SMS center number" setting inside is incorrect. Take a look and correct it if it is wrong. If it is not wrong, it is the second situation;

2. Usually the SIM card used in our mobile phones, that is, the small card is a small chip. , when it receives and deletes information for a long time, it will occasionally damage the function of the SIM card itself. The situation you mentioned seems to be a malfunction of the SIM card. Usually the possibility of such a malfunction is very small, but It still exists. You can go to the local regular mobile business hall and bring your valid ID, or use the service password to ask the mobile company to replace you with a new SIM card. Changing the card does not change the number. This is the free service scope of the mobile company!

If you have any questions, you can dial 10086 and press 0 to find manual service. I believe they will give you a satisfactory answer! ! !

I wish you a happy life! ! ! ! ——HAPPYDBW
