I am using China Unicom card and I want to make phone calls (long chat) or send text messages to mobile card users.

Compared to China Unicom, the price must be higher.

It is recommended to consult the customer service phone number, the customer service can also handle the business.

The best way is to apply for a "SMS package" that can be used both inside and outside the network. It is convenient and affordable, but if you have a lot of text messages, call customer service 10010. I have never used China Unicom, so I don't know. Can I handle it through customer service?

If you replace China Unicom with China Mobile, I know China Mobile’s cheapest text messaging service “M-Zone”. However, there are many people on the network, and M-Zone’s rates are relatively higher than China Mobile’s “Shenzhouxing”. It is expensive, so China Unicom cannot take advantage of it. The best way is to apply for a "SMS package". The customer service number 10086 can also handle the business.

As mentioned above, in fact, China Mobile is better than China Unicom in that it is more diversified, such as Fetion. SMS is free, but the other party must also activate the Fetion function, and according to Different regions differ. In some places, Fetion charges a monthly fee and cannot be sent to China Unicom and Telecom.
