1, most of the standard cards of Shenzhouxing are charged with 50 phone bills, but I suggest that you dial 10086 to manually check the balance of the number before buying at the agency, because some agencies will help you open some businesses and deduct your fees, regardless of your mobile home ~ text message is 1.5/.
It's troublesome to make a phone call: 12593 20 points for local calls and 30 points for domestic calls, but you can't use replay, just redial 1 minute. Very tricky. I don't need an ID card.
2. China Travel Card, one card per day, please consult mobile labor for details. I know this card, but I don't know the cost. Text messages 1.5/.
3, you can consider the dynamic zone. If the monthly rent is activated, it can be used for half a month, which should be no problem. The local call is 25 cents, and the long distance call is 35 cents plus 1795 1. SMS 1 cent/article.
At present, making long-distance calls is not roaming. It's from somewhere else. You don't need an ID card to buy the above three cards at the agency or mobile cooperation office. However, the cards bought at the mobile cooperation office are very expensive.
