Sony Ericsson t707 failed to send SMS.

First try to turn the phone on and off again. If not, try putting the card in another phone. If you can send it on another mobile phone, there is nothing wrong with your card.

See if there are any unsent messages in your mobile phone. If there is, try to delete it.

If it is deleted, just turn it on and off.

If you can't delete it, save the things you want to save in your phone somewhere else, and then format your phone (phone settings-general-reset-reset all).

It depends on what phone card you bought. If the package contains multiple SMS messages, within this range, you will not deduct the money for sending ordinary SMS messages, but deduct the number in your SMS package. Usually, the packet consists of short messages in the network plus any short messages inside and outside the network.

In addition, now China Mobile and China Unicom send text messages, whether inside or outside the network, the text messages are all 1 cent.

However, it should be noted that sending short messages outside the network (such as mobile to Unicom and mobile to PHS) may cost extra.

For example, if your mobile phone is mobile, the package includes 200 short messages in the network and 100 short messages in and out of the network.

1. If you send 100 messages to your mobile phone, they will only be deducted from your subscription. Now you have 100 short messages in the network and 100 short messages in any network inside or outside the network.

2. If you sent 250 short messages to your mobile phone, you still have 50 short messages from any network inside or outside the network.

If you sent 50 short messages to your Unicom mobile phone, you still have 200 short messages online, and 50 short messages in any network inside or outside the network.

4. If you sent 200 short messages to Unicom, you still have 200 short messages inside and outside the network and 0 short messages inside and outside the network. In addition, you have to send an off-line message of 100, that is, 10 yuan.
