Nokia 5230 SMS card

Try using another card on your phone. If it works, it's the card problem. If not, it's the phone. If there is something wrong with the card, call the manual service or go to the business hall. The problem with mobile phones is that you can't send text messages. The center number of the mobile phone can't be used (manual call center number), and there is the problem of setting (this is for your own use only). Seriously, the SMS software is not working. If the software doesn't work, you have to brush it. You can download other SMS software to try before brushing. You can brush it or not. It is not good to bring your own software.
