Whats the difference between the aerial recharge with the recharge card?
Aerial recharge is more convenience, no matter it is in the midnight or if there are some Chinese around you, you can apply for the service any time. There are no mistakes on wrong recharge card, on language block, on service quality. Recharge card is different; you need to confirm whether it is the right one for your China SIM card. Although it can be found on the corner shops, it is hard to get it anytime when you need it.
