Telecom, mobile, China Unicom, which card is more cost-effective? I only answer the phone and send text messages, and my friends are all from Henan.

If you want to use 3G, I suggest you use Unicom ... because Unicom 3G signal is really good. ...

If I just make a phone call, I prefer to use my mobile phone. ...

After all, big brands are trustworthy. ...

I have a classmate who uses Unicom card. Usually, there is no difference between us. ...

It's just that I often send you text messages when you still have the balance of your phone bill, saying that you have stopped working and need to pay ... My classmate finally had to change his card because of this ... and the service attitude is really bad. ...

Telecom ... My home is in Luoyang ... It's not easy to find a place to charge the phone bill ... There are too few ways out ... It takes more than 20 minutes to pay the phone bill by bus. ...
