The newly bought Nokia E63 mobile phone has the correct information center number. Why can't I always send a message?

1, if you can receive the text message, it proves normal. Of course, you can't send text messages, probably because the service center number has been changed or deleted. Check the number of the SMS service center in your mobile phone, generally: +86 138 (local area code) 6500. Please get the number of the SMS center from the local operator.

2. A good signal is not necessarily a normal network. I often encounter similar situations as you said, but it is actually a network problem, especially in rainy days. It will be fine after a while, usually lasting at most 1~2 hours.

3. Dial 10086 to enter the manual service. Please ask mobile customer service to help you solve it. Sometimes it is also a problem such as network restrictions.
