When traveling to Hong Kong, can I send text messages to my mainland friends when I buy a card? How much is the charge in Hong Kong? How much do my friends charge for texting me?

I often go to Hong Kong. Hong Kong card can talk freely with mainland friends and send text messages to WeChat. The phone bill is only a little more expensive than that in the mainland, and it is almost the same when converted into RMB. Generally, an ordinary Hong Kong card costs about HK$ 65,438+000. There is a phone bill of 60 Hong Kong dollars in it, which is basically enough for three to five days. In addition, RMB in 78 yuan is now equivalent to HK$ 65,438+000.
