I use the mobile phone number of China Mobile, and I know the other party's number. How to send text messages to Italian mobile phones? Do you need to start any business?

If it's just a text message, it seems that it can be sent directly. But when sending it, you should add'+international code' in front of the other party's number. Please note that this+sign must be added. Because'+'is an international prefix identification sign when doing international business. If you can't dial'+'on your mobile phone, it's the same to change the'+'number to' 00'. ...

For example, the international code for Italy is "39" ... Then, you must enter "+39 Partner Number" ... or "0039 Partner Number" ... It doesn't matter. ...
