The number of telecom customer service is 10000, and the number of mobile customer service is 10086, which belong to two ownership halls. Of course, there is a charge for you to call telecom customer service with your mobile phone card. The standard is to deduct the local call charges. Under normal circumstances, for example, if you call an ordinary mobile phone number, you will be deducted 20 points per minute, and if you call telecommunications, you will also be deducted 20 points.
Personally, if you want to solve the telecom problem, you can see if your friends or relatives have used telecom mobile phone cards. It is free to use their telecom mobile phone card. I can ask you what you want to know. If you are in a hurry, you can only make a normal call.
I hope my answer can help you. I hope it can be adopted. Thank you.
