About the charge for mobile phones to Hong Kong?

Why did I say so much? Didn't send it up? Say it briefly.

I started a general roaming in Hong Kong and Shenzhen Mobile. Roaming itself is free, but calling (3 minutes faster) and texting (more than one piece) are expensive. Receiving text messages is free. The opening is mainly for mainland friends to contact me, because I can't call Hong Kong directly.

Travel generally buys a disposable mobile phone card. You can sell it as soon as you enter the 7 1 1 convenience store in Hong Kong. It costs 25 cents to call the local mainland. You tell the clerk to buy 25 cents from the mainland, and they will know. The minimum face value is also 68.

It depends on how big your mobile phone is when you come. If it is much bigger, I think it is more convenient to buy a local card.
