I want to travel to Hong Kong for 7 days and get a temporary card there. I can't afford international roaming calls, not to mention the traffic. Who can recommend which is better?

According to my experience, I suggest you buy Peoples's calling cards (prepaid cards, ranging from 50- 1 10, valid for half a year) at the local 7- 1 or OK convenience store in Hong Kong. According to years of observation, it should be the cheapest calling card in Hong Kong to call the mainland, with a charge of HK$ 0.25 per minute, which has included all the expenses. This is the first time I found this card. This calling card is a joint venture of China Mobile, so it is very favorable to call China, which is most suitable for traveling in Hongkong for more than three days. Remind parents not to buy calling cards in through trains, airports and railway stations. The price will be much more expensive and there is no discount. Suggest going to 7- 1 1 or OK convenience store in the city. These stores will also provide 50 yuan-denominated calling cards, so that they will not be wasted.

In addition, this card can also be used in Macau (calling China), and there may be some roaming charges, as long as it is short. According to my previous experience, I haven't used up the phone card in 50 yuan for 10 days, and I made several calls to my friends in Hong Kong, so I can still use it when I go to Hong Kong after half a year. If you continue to recharge, the validity period will be extended for another half year.

It is recommended that you take two mobile phones with you, one is a personal calling card and the other is a domestic calling card (there is no charge for receiving domestic short messages in Hong Kong). When you see a domestic call, you can reply with someone else's calling card. This is the best deal.
