Why does my mobile phone telecom card show that the sender is 20 after receiving someone else's short message, and the content of the received short message is a symbol? Then there is a picture.

According to your description, the message you received is unrecognizable, so you don't need to pay attention to it. It's all spam messages, and there is no basic sending number. I suggest you delete the message as soon as possible, I hope it will help you! If the above information can't solve your problem, you can also log in to Anhui Telecom Tianyi Store (/shop/) to consult online customer service! Now Tianyi Store gives a 4.5-inch large-screen mobile phone at a great value, and you can enjoy the lowest price of the whole network. You can go and see/iphone/ext/4.5 big/index.html.
