I work in Guangzhou and often make long-distance calls to Foshan, Shenzhen, Shaoguan and other places, as well as Changsha, Wuhan and Kunming. Is it better to use mobile or Unicom?

I suggest you use Unicom's wireless phone. This tariff is cheaper and better because it is a formal business service industry.

Mobile local charges are ok, but not suitable for long distance.

The telecom package fee of 139+ 1 can also be 0. 15 yuan/minute.

As for the IP phone you mentioned, it is actually a callback card business, which is illegal but not illegal.

The biggest feature of this service is that it is slightly cheaper than Unicom wireless phone, but it is more troublesome to operate. The cause of the failure is as follows:

1, the calling number usually cannot be displayed or a number is randomly displayed, giving customers a bad feeling.

2. From time to time, there are unstable calls or toll-free calls with slow response, which can only be connected after several operations.

Half of the 3.9 cents will be charged in 48 seconds.

To sum up, my suggestion is obvious.

Of course, I don't have wireless phone service here All I can do is give some advice. But if you have any questions, you can leave me a message.
