We recommend a good call tool, which is more meaningful than QQ.

This tool can earn points through hanging up, or directly recharge, and then exchange points for calls.
If you do not have a call charge, the tool provides 3-minute free calls every day.
In addition, the domestic call cost only 0.08 yuan, which is much cheaper than other methods.
The most important thing is that you do not need to bind anything or a valid credential. It is safe. This is why I registered it.
The procedure is as follows:
1. registration address: shutter Registration
Or click the following advertisement to register:

2. Activate it in the mailbox after registration (it seems that Tom's mailbox cannot receive the email, and I have a friend who has encountered this problem, haha, there is definitely no problem with 163.com anyway)

3. download and install the shtter software after activation (no virus exists and many students are using it)

4. Log On with the registered account. Everything is OK.

5. A machine hanging a number too slow too waste it, don't worry, just found multiple open: http://www.91files.com /? Jemcotl1_a863bi50ax
The download is a green version. From now on, you need to register more credits and call fees.
