For the sake of love, what is the most cost-effective way for Hong Kong and the Mainland to send messages to each other?

Let him buy peoples or 3, and never take China to move. Roaming in Hong Kong and Macao is extremely expensive. It doesn't matter to you China Mobile Unicom can use any card, as long as it can send short messages.

such

Usually you send her a message 1 yuan, and he sends you a message of 0.5 Hong Kong dollars. In fact, the main problem is that yours is relatively unbearable.

therefore

1. Let my girlfriend buy a Unicom China-Hong Kong Stock Connect in Hong Kong and send text messages to each other, which seems to be 20 cents each. It's like bringing a Unicom card, which is what many students around me do. This shortcoming is that it is a bit expensive for China Stock Connect to make local calls in Hong Kong. The most affordable thing is that your girlfriend has two mobile phones, one is peoples or 3, and the other is China Stock Connect, which is specially used to send you short messages. . .

2.QQ Fetion, he can send it to you directly by computer. I recommended it, so that she can have enough balance before each trip to Hong Kong. Of course, you can also charge her in the mainland. The only disadvantage of this method is that only you can use a mobile phone, and he must use a computer.

That's all I know. In addition, my personal opinion is that I usually make more phone calls, video chat on the online interface, and say good night before going to bed in class, so I don't care about this 1, 2 yuan at all.
